Puzzling.

You can hear it jumping in first gear.

My dad drove it for the first time today, he said its in the transmission.

well the clutch baskets are known to be weak in stock form. i wonder hmmmmmm

Why only at 5-6k then.  It would at the very least be everywhere in first gear?

the only @5-6K rpm is puzzling,especially only in first gear. I would think something electrical/electronic.  Is there a power commander or such on it?

No bone stock ECU other then the normal bypasses for sidestand, etc.

it does it at different areas, not only 5 or 6k. It sounds like the chain is slipping a tooth, but I honestly I dont think that is it.

Just seems like it starts when you close to that rpm range. Dont really wanna wind it harder than that as it get more aggressively as the rpm increases.

Im not expert but, I looked at the wear on the basket itself. It didn't have any grooves worn into it allowing the plates to rotate any once in place. They had to be perfectly lined up to slide back inside.

Just quit ridin in 1st gear, problem solved!  PM'd my address for reward $$$   

If its only 1st I'd say gear in tranny.  Which is weird cause 2nd is usually the weaker one.  Sprockets look fine, unless theres a tooth somewhere thats weak.  Chain looks ok unless a link is locked and jumping a tooth, and clutch and basket problems would change gears too.

lol..... Unfortunately,  I agree as well.

ya that article sounds correct just 1 st instead of 2nd.  of course it could still be the teeth on the side of 2nd gear lol

So does this make you "out" on the LS trip coming up?  It's not ok late, I just pu bearing carrier from machine shop today and have to mod the rear for this big ass sprocket I got. New chain and a larger front sprocket will be on order next week.  I really need a good trou or free trip(if that's possible) or wife will never commit to a drive to Idaho.

well the video is marked private so i can't watch it

watched the video of the sprocket wear. the sprocket teeth are a little worn but not bad at all imo. i have seen them wear quite a bit more than than before failure.
