I have a couple hogged out cylinders from my 1986 LT250R and was wondering if anyone makes a big bore kit ?

Trinity racing does big bores for 87 to 92 I was considering a 295 bore but it seemed pricey

talk to piranha pete...search the QHQ forums for his number...u would be amazed at what he is doing...i mean it all costs money, but he does lt big bores with polaris pistons that run up to 320 or more, strokers.....

he's even working on grafting a rotax jug on a lt250r bottom end...

you might also call ftzracing. they show a long rod/stroker too for the lt250 and tecate as well as 250r hondas. Didn't notice it on their website before....

I am currently having CT Racing do a '87 250 jug for me. They are using a 74mm Kaw piston (67mm is stock) for mine. I don't know what the actuall cc will be but it's 70mm stroke x 74mm bore if somebody wants to figure it up. They are also doing TT style porting with 13.5/1 compression and a 41.5mm carb. He says it will be a beast when I get it back. I can't wait.
