That's why I said ray was great...

Is this felt at idle, or when riding? You're sure it's the motor, not loose hubs, loose chassis bearings, junk exhaust hangers, sloppy axle, etc?

What's done to the bike? Any mods that need jetting changes? And what are your jetting specs

They're great!

Not my pro design.

I was at a hard scramble on a ski resort here in Michigan. Somebody had a Bill Balance Edition XC 450 and had a pretty decent 4 mil set up in it. He was cookin' in the wide open stuff and the hills, but couldn't really ride hard enough to hang in the woods. Said it was his first year racing XC..... I asked if he posted here and he said he never heard of it.

That's not a good thing. And I hope people aren't compensating you for those habbits.

JEEZUS!

^ and? Where can you get nice mint rears for less?

Yes ^ look at Macdizzy's page for photos and instructions on squish test.

There are unite a few companies that sell different shifters. Pro design, IMS, mod quad, etc.

Awe sheeit..... Bucky ain't skeerd.

It's pretty easy. Pull the coolant hose off the clutch cover to drain coolant. I do that to get as little coolant in the cylinder as possible.Loosen the coolant hose clamps on front and rear of the head. Pull small vent hose off top of head. Remove 10 nuts. Lift top plate off. Yank the small o rings around each stud so they don't bind up when lifting the shell. Now lift the shell off. Domes may stay in or flop out. Doesn't matter. Discard all O rings. Use clean shop towels to soak any coolant out of the cylinder. Spray the bore with WD-40 so it won't rust. Use clean rags and brake cleaner or laquer thinner to clean the mating surfaces and then begin re assembly. Place the larger o rings in the bottom of the shell. Use a SMALL dab of grease to get them to stick in their grooves. Place the domes in the shell with their O rings. Flip the shell and domes and hold the domes from the top side. Slide it down the studs. Stop at about 1/4" and look to make sure O rings are still seated. Drop the shell and domes down. Insert small O rings over each stud. O ring the top plate and slide it down. Finger tighten the nuts. Some won't do this part, but it helps seal multi cylinder set ups. Loosen the base nuts just a touch. Step torque the 10 nuts in OEM pattern or from inner to outer studs. Tighten up coolant hoses and vent hose. Check squish & compression. Fill with coolant. Check for leaks. Put plugs in it and fire it up.

Ya, no offense. But you're OP, you're a big dude. Single arms set up for you is sketchy at best. Especially if you wanna run whooped out hills. Don't forget open enrollment for health care is in the next couple weeks if that's the route you choose.

^ big socket = 32mm

^ not sure if that's legit? But things go bang on the other side of the piston, so not entirely needed if you use sealant or LOCTITE on the outer race so it won't spin. OP, why do you think they won't fit? They come with them correct? They are rubber and stretch. Just picture in your head how you can walk it over the journals and in between the journals so it can stretch up around the rod. It's fine. I'd imagine little Asian ladies in the factory are putting them on in a matter of seconds.

^ haha

Troy is spot on. You say you want a drag bike, but right now you have a trail bike and a weak one at that. Troy has a pretty common and effective combo wrote out from motor to tires. That is probably the best route to go. Gonna have to do a lot of research if you wanna go fast consistantly for bracket classes. Also, yes to your drag and hill set up. Just build a suspended set up you can bang the hills on then put struts on for drag day.

Sweet. I was looking at those and wondered what the read outs would look like. Good info. I appreciate it.

Should be good to go

Ya

Small aluminum plug? Clean it with brake cleaner, push a new plug back in with LOCTITE sealer/thread locker. Make sure the vent on top of the case at the rear motor mount is actually working.

Yeah.... But I get where he's coming from. Can they design a hell of a shock. Hell yeah. But when it comes to having it set up to your bike, weight, ride style, etc.... I doubt they are taking banshees out every weekend to the dunes, motocross track, and trails to learn exactly what the shock needs before it's sent to your door.

What data logger is that chart from? Does it read off a simple sensor on the clutch side and output side of things?
