TRX250R motor swap?

[motorhed]

whats up? ok so heres the deal i just cracked my second case half in two years on my 86 TRX250R. i love this motor when its running good but it has honestly given me a shitload of aggervation. the rest of the quad is in awsome shape and now im thinkin about an upgrade. i took the 250 motor out and before i go through all the bullshit of splittin that case again and buyin new parts i started to ponder putting a bigger motor in there. what im cerious about i guess is does anybody know of an easy engine swap for more power with minimal alteration to the existing chassis? i know u can make just about anything fit in there but im a college student and funds are kinda limited and im shootin to have this thing up and runnin by next spring. im considering any sugestions at this point i just want to go faster! thanx

well if you wanna stay with a 250cc id say get the counterballanced tecate motor from the 87-88 T4, they are the most powerful 250cc atv motor available, well unless you get one from a tiger 250 but that would be hella pricy. i you wanna get a bigger motor put a zilla motor in there and if you wouldnt mind the crazy vibrations you could stick a cr500 or kx500 motor in it.

i was thinkin about the zilla motor my buddy had one that thing was fast as hell how hard would it be to mount it in the 250s chassis though that what im worried about

i dont really know, probility not too bad, just gotta make some mounts and probility get a pipe made for it
