TRX300 Engine Mod's

Thinking more and more about building the engine on my 300.

What are some good engine mods? No B/S mods just pure power mods.

No BBK and no pipe...I want this bike to be as trail worthy and quiet as possible...I've already have my fill of BBK's and annoying pipes.

Heres what I'm thinking of.

'88 or BR Cam

Wiseco Piston

Port/Polish head

Clutch kit (while I'm in there)

BR timing chain

What else do I need...with these mod's will I need a significant fuel upgrade, or will adjusting the stock carb suffice?

I would do all the things you listed and add a jet kit to the stock carb. that would be a fun little quad to ride then

To retain reliability Id probably keep it stock bore. Wiesco HC piston. Big red 250 timing chain for sure. 459/102 cam, or BR/88 if you dont have a lot to spend on a cam. not sure about the port/polish but it should help. Clutch kit (EPI competition?) should make it more fun to take off from a stop but thats up to you.

And then a filter, either a 300EX carb or increase jet sizes on your stock carb.

A 00-06 Big bear HMF or a FO4/FO14 tractor muffler should be added too before jetting.

should be a bad lil bike then.
