B. Let him know up front your asking for what it'll cost to replace it....easily

I've been 43 on this

57 mph on a dirt road with my GPS in hand. It was still climbing but I got scared. It's a new build so I'm still working out the bugs

Anyone have some custom wheel/tire packages on their warriors? Post some pics with the size and brand. I wanna see what's out there

Wow. Mine was $799 new in (I'm guessing) the early 70's.

Found a Mongomery Ward sticker on it today while tearing it apart

I took it out for a slightly more "spirited" ride this morning. The bike definately needs to be jetted with the pipe and filter. It doesn't like to start hot. Also I think I'm done riding it until it has a permanent gas tank on it and better brakes ( the factory brake is non existant...

Well, I picked up a new jackshaft and some higher quality bearings. There's a lot less wobble in the shaft now. I took a quick easy spin yesterday and everything seems ok. The shaft never got hot. Thanks for the suggestions guys!

That was my initial thought. Maybe I'll pick up a new shaft and some better bearings and give it another go before I start chopping and welding.

The bearings and jackshaft came in a kit from asuza

When I put everything together, I could feel some wobble in the shaft. I think it was a combination of cheap bearings and both bearings being inside the framerails while both the pulley and sprocket hung off opposite ends of the shaft.

The plate worked great. I've gotta trim it a little to clear a bump in the fan cover.o took the bike for a quick ride. Acceleration was great with the current gearing (14 tooth on jackshaft and stock rear sprocket). I hit 47 mph and was still climbing when I broke something

Made up a throttle bracket today at work. If it actually fits ( and works), I'll make something a little fancier.

Got it running yesterday! Still needs a throttle setup, brakes, a fuel tank, and a different header. I shot it down the driveway once with a tank between my legs and a finger on the linkage....then I decided not to visit the hospital

Haha! Nice. So how's it run? What gearing are you using and what mph is it getting you?

Cool mower!

No. The pipes were rotted right through at the block and the fuel tank was nasty. I just wanted to confirm the motor was ok before pulling the bike apart

We did manage to fire it up before taking the bike apart

I know nothing about snowmobile engines. I looked it up and it's a 338

One week later I found its twin in much better shape
