LT250r Big Bore

[xKroniK13x]

Do they exist? I know TRX250r's have the ESR310 kit, do they work on an LT? Is there something comparable?

My dad has always said he wishes his was around a 300, so I thought it'd be cool to find a kit.

unfortunatly not any more, ftz usedto offer one, and im sure some of the big names did, BUT the lt250r was faster straight line out ofthe box than the trx's were, just didnt handle as good.
in all reality he dont need a big bore for power

drQ or aaen pipe ( aaen is very simmaler to the dr q and well less than half the price of a q pipe) 38-39 mm lectron carb, vf2 reeds or a simaler rad valve set up, pro design usedto offer a cool head with differant dome for them, and they can still be found,
getthe jetting right and dial in the power valve ( im assuming its a 87-92 motor)

or do all the mods listed to a 87 motor since the 87 made the most hp stock anyway,

or a lt500/250 hybrid id love to go this way just not in my budget right now! a rm250 swap is also a option, and has been done and looks sweet, with the right side dirt bike pipe,

i dont think there is a bolt on kit available anymore.. you can bore like .120 over and use a polaris watercraft piston that get you some more cc's. there is also another way af using a thicker la sleeve and i believe a yz250 piston that will get it over 300cc's. ftz used to do this setup.

if he calls ftz they may still set one up for him..i believe i heard of someone having them do one a few years ago. it is not going to be cheap though.

i talked to ftz a few weeks ago and there not offering anything for the lts not even pipes.

i know on a stock lt cyl you can go 100 over with a yz piston, iv also herd of the polaris watercraft set up, i personnaly dont truth the idea ofmit but if it works it works
