Big Red Performance

[lndy650]

im sure someone has thought of this but this winter im going to attempt to install a 4 valve 350x or 250x head on a big red engine. then use a custom sleeve with a 350x big bore piston making it about a 350....we will see if it works. i also know gears that will fit the big red engine to get more top speed

wow, that would be crazy

[lndy650]

ya im 90% sure i can make it work...

[Russell 350X]

Let us know....sounds interesting.

I want to hear more about these mystery gears...?

[lndy650]

not really mystery gears lol just think about it...

[Thorpe]

Using SX gears...?

the 350x head doesn't line up does it?

[lndy650]

cam chain is on the same side and the bolt pattern is the same thats as far as ive got so far...

[Erics350x]

Reason i was asking is, I tried to put a 350x head on a TRX300 a while back and there was something like two bolts that didn't line up.

It would be cool if that works out. I wonder if the cam chain will fit? I have a couple spare 350x topends if you need anything.

thanks ill see how far i get...you might be right i was just eyeballing the stud pattern but it looks identical
