My FIL has his two-seat powered parachute in my garage. Everytime I look at that Rotax 582, I think saw.

JJ, haven't competed againist or heard of any other 500's around besides the ones I've built. I do know Randy Irwin who hangs at Horners and from Cottage Grove. He built a Honda 450cc 4-stroker hotsaw a couple years back. Don't know this other guy.

I saw this one run up in Oregon in the spring. I was offered a chance to run it, but I chickened out..... lol. I did run two of his other hotsaws though.

IIRC, he said that he had built this saw himself.

Another point on bikesaws, look at those saws Dennis has pictured. The massive job of the conversion has already been done, just a simple tweak now and then will keep them competitive as long as there are bikesaws. Kartsaws did away with regular saws, bikesaws did away with kartsaws, is doubtful there will ever be a power plant that will put a well designed bikesaw on the shelf. Two stroke engine development has reached it's peak and now are being phased out.

i remember it. madhatte ran it, he had a pretty big grin on his face.
Is that one a snowmobile engine? It sounds like a JLO engine.

No, I think it is a 500cc Honda. In person it sounds COMPLETELY different than in the vid. The volume was deafening.

Its a CRF dirtbike motor. I believe he bumped the compression as well as a few other mods.
He runs 404 high tooth.
In this run we had Bob's Farleys neighbor threatening to call the cops because it was so loud.
I was too close and the sound overloaded my cameras mike.

It still sounds pretty awesome. I'll bet Bob's neighbors have wanted to call the cops on more than one occasion.
I saw Rupedoggy's bikesaws, he's got some sweet machines, a 250, a 325?, and a 500?.
Stihl made it's own hot saws and .404 high tooth chain to go with them at one time.Redirect Notice
I think this is them? Maybe someone else knows more about this.

Yeah, that's Randy Irwin. CRF 450 Honda. He phoned me quite often when he was building that saw.

I'm pretty sure Jerry's 175 hotsaw is a honda, and was originally built by Chaunsey Varney. That saw has been around for along time. I first saw it in the back of Chaunsey's pickup with his other bigger Honda at Loon Mt. N.H. STS in 94 or 95.

Well it's about time to start another thread with some Hotsaw video. Here's an example.......TJ Bexten making test cuts to decide which hotsaw (250/310) to run at the West Coast qualifier March 2011 at San Louis Opisbo, Ca.......250 1st/310 2nd
We saw'd the doug fir rounds in half for testing......gave us more of the true time in the wood......then went to white pine to test the chains. TJ didn't have much time at all cold start racing a bikesaw when these video's were taken. Most all his cutting came from hot start cutting with his 500. He cuts log for a living and is a skilled chainsaw operator, so he was a quick learner.......and now days is making runs in the low six's.

These cuts are in Western white pine, much softer than the doug fir. The 310 and 1/2" chain cut it pretty good, the 250 with 404 is to hungry. Ended up filing one more time but still found it to hungry. We now have the depth height right on the money, but more than half of the chain had to be filed back. Not a good design and very expensive when you loose half the chain right off the bat.
Dennis, is that the 404 high tooth? I had heard the depth gauges looked really low but 'd never heard from some one that had ran it.
