144cc big-bore kit for Kawa 125 models?

  1. Has anybody tried to fit the cylinder and piston of the KLX140 onto the 125cc street legal model?
    Both have a stroke of 54.4mm but the off-road version has a 4mm bigger bore (58 instead of 54mm) giving it 144cc compared to the 124cc of the enduro.
    20 extra cc is about a 15% increase - should make a difference!
    Seems to me that this would be a quite easy and cheap conversion using Kawasaki factory parts.

    Any thoughts?

    Btw, the off-road exhaust fits onto the enduro, looks good and is not too noisy.

  2. If you've got the time & money there's no replacement for displacement........go for it!! Any reason why you didn't go for the klx250 in the first place? I got a D-Tracker250 & think it's a bit underpowered BTW & have dabbled with the idea of a BB kit.......is a man is never happy with the power he's got...lol

    Seeing as you live on Phuket & letting a bunch of @#$***# at Kawasaki (Phuket town) loose on your bike might be a little scary. I have watched them assemble a top end on a ER6 & a torque wrench was never used at any point!!! I know an English mechanic in Chalong with 30+ years of experience behind him, with pretty much a full machine shop of engineering equipment. Let me know if you want an introduction.

    cheers joel
