    I need a new "clutch boss" but nobody can get one as they are on backorder from yamaha for at least a month supposedly...



    Ronnydog used TTR clutch on his big motor build... Can I just buy the clutch cover and clutch assembly from a TTR (which one? 125? 225? 230? 250? any?) and bolt it right on?



    It looks like there are TTR125 clutch covers and clutches on ebay for ~$40 each, so if I could do the whole swap for $80+shipping that would be way cooler than not being able to get the tw200 part forever

    Ehhhhh it is the TTR125 parts that are cheap on ebay.. Don't even see any covers for sale for the 225 and it looks like that is what Ronnydog was using.

    Info:

    The TTR125 clutch cover will not fit on the TW engine.

    The covers from the bigger TT/XT engines (max. 230ccm) will fit.

    Operose, the shaft spline on the left is the TTR and on the right is the TW. I used the TTR shaft with the 6 speed. I do not know if there are dif years with dif shaft splines or if the XT225 will work. Clutch cover I used is the TTR and it fits.

    Thanks Ronny. I've probably dug too deep into the wallet for the bike already this year, so this probably won't happen. Trying to work a deal with mac for a used clutch boss he has in stock.



    This should be very useful info for anyone else thinking about the conversion though!

    Attention,

    it is probably necessary to change the pinions of transmission.

    The ratio is 73-22 or 74-20.

    Is then necessary to disassembling…To keep that d' origin. change 5 disc Clutch, to 6 disc with 6 shock absorber (made Christddel )
