The Motion PRO stuff is top shelf, well designed, well made, and looks pretty on the tool wall, too.

Throw a wet rag over the top to catch the sparks and one down inside. Set your welder like you're trying to weld something and get some penetration, don't lay a cold bead on top. Use a MIG or stick and weld a bead about 1/3 of the circumference of the race on one side or even less on 2 sides...

I might be intersted if the cost isn't crazy high.

That's the best part ! Can't lose that. Inline bikes are a nickel a dozen.

Maybe if it was an inline 4 ?

Tranny's not wide enough for 6 gears that can handle MrMaxx's torque, LOL. Already has issues.

I would consider a different differential comparable to a different rear sprocket. Not an "as shipped stock" machine, just regeared to suit the application better.

52 years ago or thereabouts I was tinkering with my buddy's Suzuki 124 dirt bike and took it for a test run through the neighborhood. I had welded up a tuner for it (no aftermarket tuners back then) so it was obnoxiously loud. I met a cop and decided I could lose him in a field about 1/2 mile...

That works well but it's kinda hard to do on a steering head. Plus, both materials are steel so the race will grow at a similar rate to the frame.

Sorry, I didn't even bother to read your entire post - I was in a rush to head out to -5F to get the machinery running. My experience is the same method as your's but when cool, the race usually contracts enough to lift it right out. If not add some weld.

I'm not familiar with the race removal on a V max but a well known trick in a truck or trailer shop is if you have a welding machine nearby (MIG is best), lay some wet towels all around to catch the splatter and run a small bead about 1/3 of the circumference right on the race in a couple of...

Do you guys worry about any shavings or debris going in ? Set it at TDC on the exhaust stroke and blast it with a small air hose inside the chamber 25 times ?

LOL, you probably won't see Santa for months - he and his elves are staying at my cabin in northern MN sending out e-gifts, flying through data on my terribly slow Hughes Satellite service. 60 in TV's take hours !

If this outfit spent tens of millions (USD) on their system, they MIGHT be close to the reliability, longevity, and performance Yamaha built in. If we didn't have ethanol in our fuel, the OEM setup has the potential to run perfect close to 40 years after assembly and tens of thousands of miles...
