07 1k transmission problem

[fbmbks]

Last winter I switched to an 03-04 trans and it seems to be slipping, I get on it hard in first and the revs will get higher and you will eventually feel it catch, I'm 90 percent sure its the transmission and not the clutch bc it has a brand new clutch in it, any ideas?

I don't see what could be causing it to slip inside the trans. pretty sure your looking at a clutch issue. did u properly adjust clutch or maybe try bleeding the clutch lines

[Mr.Grey]

This is most likely a clutch issue. If its not properly adjusted or not enough spring pressure for the power it's making it can drive through a brand new clutch. Trust me I know I've done it many times on a stock hand clutch and a brand new drag pack in my bike.

What kind of springs do you have? Of you are running stock you should try some Brock's stiff springs for added pressure. And if that's not enough you can shim the springs

agree with above
tranny is 2 gears meshing together
either in gear or out,,,

Hmm, guess ill mess w it this spring, it does have stiffer springs and it's a stock motor
