Thats more like it

December when ones mind turns to snow. Sadly its not cold and theres no snow yet but whaddya gonna do?

Last weekend I tried firing up the '98 Jag but she was a no go. I farted around troubleshooting for awhile and finally found that the fuel pump was failing to chooch. This was a big setback, I'd intended to spend the day replacing the track but ended up troubleshooting the day away...
I guess this finally makes the '98 fit in around here, getting its chance to be a dead sled.

I was ordering Christmas presents on Amazon anyway so I added a Mikuni square, single output pump kit to the order. Tonight I finally had time to get the kit in place. Turns out the square single output pump is REALLY simple. There are 4 screws to take it apart, 2 gaskets and a diaphragm and that is it. I replaced a couple fuel lines while I was there, its amazing how long the original lines last. I put some tygon (yellow) lines on, we'll see how they last. The clear hose is usually the worst, it gets hard and doesn't seal. Blue is second best and yellow is supposed to be the best, we'll see. I need to get some clamps, they didn't come with them stock but you might remember a couple years ago on the trail with my El Tigre when the fuel line came off one carb. If I'd kept pressing on when that happened there could have been a nasty fire...

Anyway I got it all buttoned up and on the 15th crank just as I was about to lose hope it fired up. Ran rough for a little while but finally smoothed out. I think there might have been a hint of this problem last spring when I bought the sled, it would run but would occasionally stumble and the sled would about pitch me over the handlebars, now its much smoother. Next step is to put it on the trailer and get it over to buddy Chuck for a track replacement. I dunno what the previous owner did but the track is missing a bunch of lugs, looks like somebody got after it with a hot knife.



Earlier in the day I'd gotten the '91 Jag running, that one also needed about 15 pulls but no other real work. I think it needs some clutch work, it was awful hard on gas last winter. I'll ask Chuck to take a look at it too. Last Monday I got a SAM pass for it so that sled is ready and legal to ride. The '98 still needs to be registered, I'm hoping this Friday I'll get a chance to run down to Worcester...

Working on sleds in August?

So unlike me, I usually wait until it gets cold, then I have to rust to get stuff done...

Anyway last winter I tore the engine on the Pantera all apart and then lost interest since it snowed so much. Now I'm back to working on the tin.


Initially I tried to cheat this and paint it a bunch of times with high build primer and that did take out some of the rust pits but it would have taken a year of painting and sanding so I finally mixed up a bunch of bondo and filled the pits giving the whole surface a thin coat. I knocked that back and it it with the high build to fill the scratches from the 100 grit sandpaper I was using. Bondo clogs sandpaper bad but 100 grit works better. I need to knock back the primer with some 320 grit in a block and then I think I can prime it one more time and paint. I'm not looking for perfection here but something way better than what I had.

Need to do the pipe while I'm at it but I've found that high temp paint needs a good clean surface to stick to. I did my '70 Ski-Doo pipe back years ago and it just flaked back off quick...

More putting away

Two weeks ago I managed to get the rest of the sleds put away. The '98 Jag fired up easy, its got a weird bog at part throttle that seems almost like ignition cutting out. It seems to go away as it warms up but as I've only ridden it around the house twice on the grass I'm not sure what to think of it yet. The Grand Touring fired right up too. I was surprised, after sitting for a couple months I expected the battery to be dead.

Sadly the Polaris Cobra fired right up but played its game of running only on one cylinder. I think thats got a leaking needle in the mag side carb. I'd forgotten and left the gas on and the bottom end on that side had a bunch of gas in it. Interestingly when that sled fouls a plug it FOULS a plug. I'm 1 for 4 cleaning them. My final effort involved carb cleaner, a torch and sandpaper. I did finally get it running right on both sides so I could get Seafoam gas additive into both carbs.

The Jag and Cobra got washed and waxed. I used some "Wet and Black" on the plastic on the Jag which seemed to darken it up some. Like the '91 I managed to get the windshield off the '98. It uses the same kind of screws as the older sled although it also uses some o-rings. I broke a couple of the o-rings so I'll need to replace those in the fall.

I took pictures of the Ski-Doo but I doubt I'll get to sell it this summer. Probably I'll hold onto it and sell it once the snow flies again this winter.

The track on the '98 Jag isn't fantastic so I asked the guys over at Vintage Sleds if I should get the same again or go bigger. The sled came with a .75" lug track but for about the same money I can go 1", 1.25" or 1.5". The consensus seemed to be 1.25" so I'll save my pennies and pick one up later this summer. Hopefully it'll make for a nice ride in powder snow which will be real handy if we go to camp this winter which is something I really want to try to do.

Stuff is still going on

Yeah the season is over, the snow is gone, the rains have come, well the rains SHOULD have come but haven't. That doesn't mean the sleds get neglected, or it SHOULDN'T mean the sleds get neglected...

Saturday I got some time to start putting the machines into storage, step one was to pull the windshield off the '91 Jag, the windshield comes off that sled easily so I pull it, otherwise the tarp will pull on it all summer and fold it in effectively ruining it. Then I added a couple ounces of Seafoam gas additive to the tank. I've been adding Seafoam at every fill up so this dose wasn't all that important, I also managed to run the tank down pretty far the last time I rode the sled so I didn't use very much.

Then I scrubbed the sled:

I used normal carwash soap and my normal car scrubbing sponge. This is a chance to give the sled a good check over, look for anything broken or needing attention. I found some cracks in the fiberglass of the hood but nothing too bad. The I fired it up and ran it around the yard to its summertime spot. I was very pleased in that it started right up no problem. That got the engine warm and helped dry out the hook and engine compartment. Then I waxed the hood and put two yogurt cups with mothballs in the footwells to keep the mice away.

There are a couple more steps, I need to stop and get a tarp for it, the canvas cover I have will get killed by staying outside all summer. Then I'll start it one more time and turn off the gas so the carb bowls empty out some. I'll shut it off before they run out, 2 stroke engines really don't like running out of gas. The bowls will still have some gas in them, theres nothing I can do about that but having them half empty will help to keep varnish from building up on the jets and causing trouble.

Finally I'll hose down the whole engine compartment with WD40. This gets rid of any remaining water and puts a water resistant coating on the metal parts. I did this last year on this sled and I was very pleased with the results. Its especially important since I don't have covered storage for the sleds although even if I did I think I'd still go ahead with it. I wish I'd been doing this on the Pantera, if I had I wouldn't need to repaint the tinwork...

Its not a dead sled but...

Picked up a new-to-me sled yesterday,


Its a 1998 Jag 440 with just over 3100 miles.



Its in good shape although the hood is broken a little at the hinge:


The guy claims the wind caught the hood while it was open but he's repaired it with some tin on the inside and fiberglass on the outside. It looks like a decent repair although I'll keep my eyes open for a replacement hood. It'll also need a track in a year or two, I priced the sled with that in mind...

I bought this sled because my '91 Jag beat the snot out of me last winter. When the trails were nice and flat it was a nice sled to ride but when they were bumpy it wasn't. This '98 has at least twice as much suspension, this is the last generation of the Jag, they stopped making them in '99, its got the FastRack long travel rear suspension and should be a much more comfortable ride. Its got aftermarket plastic skis with good carbides so it turns great. Starts real easy, and with a single carb its easy on the thumb and should be pretty easy on gas.

Overall I'm excited, this sled should have all the good my '91 has plus be more comfortable to ride a win overall.

Call it

What a winter its been but as I write this the snow here in north central Massachusetts is about gone. They tell me theres still riding up north but sadly I have no time for that and honestly with such an epic winter I'm about all done. I did something like 300 miles this year which is a record for me. To get to that mileage we had at least two 50 mile rides which are also records never mind having just an epic amount of snowfall.

My last ride was actually several weeks ago, I went out by myself for another 50 miler. Angie was willing to go with me but the snow conditions were less than idea for a liquid cooled machine and I was worried the Ski-Doo would overheat. The Jag just ate up the miles no problem and most of the places I rode we nice and flat so its less than fantastic suspension wasn't a big issue. After a whole season of riding past it I finally found a spot lots of people had taken pics of and Ben had told me about:

Looks to me like some sort of railroad or maybe a trolley had run through here. This runs down through the Birch Hill recreation area by the parking lot and I think the tracks must have continued down into Lake Dennison park. I didn't realize it before but I can see them as tracks now.

The Jag seems to get about 10-12mpg limiting me to around a 50 mile run which is fine as thats about as far as I can stand. The sled has good front suspension but the rear end only has a few inches of travel. I've started looking around for something newer with more suspension. Randy tried to warn me about that last year but I didn't listen. My plan is to sell the Ski-Doo and Jag and get a pair of newer machines like a Z440 or newer Jag DLX, or maybe a Polaris with an Xtra 10 or Xtra 12 suspension. Something I can ride on the whoops without getting beaten to death.

Stupid trailer

Seems like I've had to fix my trailer just about every time I've used it this season, clearly its due for a major rebuild in the off-season.

You might remember last time the passenger side taillight fell off. This time it was the license plate which was fortunately held to the trailer by the wiring for it's light.
Heres an in-progress pic of the repair:



I actually had to do a fair amount of work for this one, the bracket that held the license plate was just gone, a piece about twice the size of a quarter was left along with one of the bolts that held the plate. I ended up having to cut that bolt (and the palm of my hand while I was at it) to get the plate back off.
The repair was fairly simple, I welded a piece of corrugated pickup bed repair steel to a piece of 1/8" flat stock, then drilled holes for the plate mount and welded the flat stock to whats left of the trailer. The welds are NASTY, there wasn't much to weld to but if you can't make 'em look good make 'em big so they won't fail.

In the end I actually made the corrugated part too big because I didn't pay attention to how the plate light I'd bought mounts:

I'd added the tab on the right to hold the light which actually mounts perfectly above the plate. Oh well, I'll fix it when I fix everything else. Using a big plate like this will keep the license plate from getting bent as much.

To weld in the plate I needed to remove the tail light and of course the stud spun, so I ended up cutting the nut that held it on so that had to be replaced as did the plate light.

Monday night I went to the snowmobile club meeting and on a challenge I decided to ride in. About halfway to the parking area I hit a big bump and the running lights went out on the trailer. The brake and turn signals still worked though. Since I didn't have far to go I just kept going.

Today I finally took time to figure out what was happening. The first step was to prove it wasn't my truck which was easy, put the meter on the plug at the truck and it was fine. So then I went to the trailer and removed all the bulbs with the meter connected and set for resistance. In a normal world the meter would read some level of resistance while the bulbs were installed and open circuit (1 on my meter) when all the bulbs were removed.

In the pic above the bulbs have been removed and the meter is still showing a connection. Since I had recently worked on the trailer I automatically assumed my work to be faulty. I pulled the new tail light and let it dangle from its wires, when dangling its not grounded so it couldn't be the short. When that didn't help I was starting to get worried about one of the wires where they come down from the hitch. I got under there and started looking around and thats when I noticed the running lights under the tail of the trailer. When I got under the tail I found the wire running to them had been pinched in a piece of angle iron that had been used to strengthen the failing rear crossmember. When they'd welded in the angle iron they captured the wire between sections of weld, what a dumb move.

Those running lights had never really worked anyway so I just cut the wire. They're in a crappy place, under the tail of the trailer so they get whacked on the ground when the trailer is tilted. When I rebuild the trailer I'll flush mount them to the rear of the trailer and weld a frame around them to keep them from getting hit. Thats how my last trailer worked and it was a pretty good system. I'll use LED lights which are thinner and less likely to get hit anyway.
