is there a big bore kit for the quadzilla. I just purchased a 87' 250ex frame for $50.00 just needs an engine and swingarm. I am choosing this engine because it is arguably the fast engine ever put in a quad, and it's 2 stroke, goota love that smell. Anywho I am building one helluva woods racer and any help would be appreciated.
i am sure that there is a big bore kit out there, but i dont know if it will push a zilla to 700cc's. thats a bunch of 2 stroke cc's [img]/wwwthreads_images/icons/smile.gif[/img]
it sounds like an interesting project, good luck and keep us informed.
Well Wiseco offers a 3.5mm over bore kit for this engine, which bumps displacement up to 540cc. However, you may be able to find a company that offers a big-bore cylinder to the Quadzilla, but offhand I'm not aware of anyone.
If you are gonna put any engine in it why not use something else. Sure the Lt500 had the fastest engine in a quad but remember when that engine came out it came in teh RM500 and it was the slowest and most unreliable open classer. so u might bebetter off finding a engine with a better re.
also a 700cc or even a 500cc engine is too much for a 25oX frame...you will shake/break the bike apart.
