Update: I decided to purchase a brand new Comet 208306A 102C clutch. It has the negative 0.20" offset. According to Comet this is the clutch I need for my 1981 Trailfire 440. I got it on Ebay for $166 shipped! I couldn't pass it up at that price! It is supposed to arrive on Monday. I know this ...

Howdy All, I am back working on my 1980 Liquifire track and suspension swap into my 1981 Trailfire as the snow is all gone now. I am in the process of preparing the suspension. The previous owner of the Liquifire really cobbled up the rear upper idler assembly. He used 4 spacers on the assembly. See...

Update: First I would like to thank Schavejdsnow for helping me solve my problem! Thanks a million John! So here is what we found out. The Comet 102C Clutch (Incorrect Clutch) that was on my 81 Trailfire can't possibly be the correct one. This sled has has had numerous things done to it by the PO an...

Howdy all, I recently rebuilt the 440 and now have 26 miles on the rebuild. I am slowly working out all the bugs on this sled and having fun doing it. I noticed the clearance between the primary clutch backing and the vertical framework that the crankshaft passes through is very close. Probably 1/32...

Well at least you got it running and got to ride it. Make sure the rubber carb mounting flange is good. Check the two bolts for tightness and the rubber clamp too. Check with ether to rule out a vacuum leak. By the way if you don't have the factory air box get one! Running without it will result in ...

Have you checked the float level? It may be off since you picked up the rear end and it died. Do you have the technical manual? The float adjustment procedure is in there. While holding the carb upside down the float arm should be parallel with the carb body. Make sure the floats actually float in f...

Howdy All, I purchased a nice Trailfire Backrest Kit about 3 years ago and have a question regarding it's installation. Do I need to drill a hole in each side of the tunnel, just to the rear of the seat strap attaching bolt, for the grab bar to mount to? I don't see a hole in the tunnel on my 81 TF ...

A few things to check. * Make sure you don't have a sticky or frozen throttle cable. * Make sure the threaded cap, where the throttle cable connects, didn't loosen up. This would raise the slide valve and needle causing increased RPM's. Happened to me once. * Make sure the air screw is set to 1-1/2 ...

I just noticed you are in Pacific Junction, IA. I’m just on the other side of the river at Beaver Lake! That was some storm! I spent 5 hrs digging me and some neighbors out. After that, I tried riding my TF 440 on the lake today but there was 6” of wet slush under the 8-10” of snow. All on top of th...

Sure sounds like the choke is not adjusted correctly. To adjust correctly you should have at least 1/8" of free play at the choke lever on the dash with the lever in the half choke position. With the dash lid closed, adjust the choke while simultaneously trying to tug on the choke lever on the ...

Make sure the crankshaft is nice and clean and rust free before you install the crankshaft seal. Make sure there are no ridges in the crank either. Otherwise the seal can become damaged during the install and have a shortened life. I just installed new seals on my TF440 during a rebuild and used a l...

Those are great pics! I wish we had a snowmobile trail system here to ride to cool places like that!

Howdy All, We received another 5" of snow on Tues night so school was cancelled. I stayed home with the kids, so we decided to take out the 81 TF 440 for a ride on the lake. :sled: . We rode 8 miles and I now have 18 miles on the engine rebuild. Here is a video that my 9 yr daughter Piper shot....

Thanks everyone! That clears that up for me. When that day happens, and I need a tow, I will know what to do.
