Wow....good job. Just a question, I see orange sealant. Back in the late 90s I bought a tube of sealant from my Deere dealer. They followed the trail of substitution and it ended up being some orange stuff made by GE. Would this happen to be what you used?

Warm starts seem to be an issue with these. One of mine, if you stop along the trail for over 5 minutes you better plan on 30 minutes. Backfiring doesn't sound normal. My mind goes to a lean condition when I hear backfire but it could be an ignition timing / flaky CDI issue also.

That looks correct to me. Here's that portion of the wiring diagram. The black wire of the CDI is connected tobthe with wire in the harmes and the brown wire if the cdi is connected to the black and white wire in the harnes. The reality is when the key switch or kill switch is in the position to sto...

- The white sealant was factory sealant. - I've not used the permatex case sealant but some have said it's similar to the Yamabond and Threebond case sealant. - I've only ever used the Tiawan pistons (SPI, Lemans, part Unlimited), so no comment on pistons. - Your thought on returning the 2 intake oi...

The dome of the Invader heads were shaped differently. The Liquifire engines were supposedly "de-tuned' to improve longevity. Those that know way more than me about squish bands will recommend using the Liquifire head with the aftermarket pistons available today. Eventhough I do have an Invader...

Welcome. Looks like you have quite the project there. Don't be afraid to ask questions. The air boxes in the one photo appear to be for a Kawasaki Invader. The Invaders used a very similar motor with a few small difference. Cylinder heads is one of the differences. I believe the liquifire heads have...

About two weeks ago Larry and I made the trip to the Ogemaw Hills Vintage Snowmobile Show. Last time I went to this show was literally a few days before the world shut down for the RONA. It was good to return, I've always enjoyed this show / ride. This year was by far the largest number of sleds I h...

What model and year sled?

As always great writeup Brian.

I know several have seen this one before but thought I'd share. I bought this modular helmet in 2013 and had a local graphics do the wrap. It honestly didn't turn out quite like I hoped but for what they charged me I'm OK with the results. It has made two trips to the RWTC....lol. 20250227_193658.jp...

As I was passing through the shop today I grabbed a shaft from a 80 Liquifire project (same shaft and bearing). The splined shaft should be hanging out of the bearing roughly 0.400".

It's been quite some time since I've worked on chaincase stuff but on my Liquifires I know the shaft does not come to the end of the RA014RRB bearing. The inner race width of the bearing should be about 0.844". The secondary shaft is turned down to go through the 7/8 ID of the bearing race. Tha...

Can't wait for your report. I've been thinking about making the trip out there again.

Looking good.

All of the bearings should only have a flange on one end.
