Need some ideas for my 300 engine!

[Ride300ex]

I have 2002 300ex with jettings and its just not enough for what i wanna do. Ive lately put alot of money in my bike though and want to keep the bike! What should i do for more power? Bore? or would a new engine be better ?
Any suggestions would help!

thanks

Call four stroke tech and ask them, you'll be happy with their answer :D

Ok ill do that .. anyone else have any suggestions!

port and polish, bigger valves bore it out to a 330, a web cam (with hardend rockers) 11.5:1 hicomp piston, bigger carb and an afermarket ignition if that isnt fast enuff 4 u then u need a 450

Give GT Thunder a call and ask about his 350 big bore kit. He is great to deal with and has reasonable prices on all his motor work.

Just do what is done to my motor, I love it!! And liek someone else said, if thats not fast enough then you need a 450 cause this is faster than a 400. All my mods are in my sig.

i had a 300 w/ 11:1 wiesco (stock bore), ported head, white bro's cam and valve springs. and without spending a bunch, it was pretty quick, and was prolly about the same power as a stock 400ex

FST 330 11:1 is awsome.

You'll want to get the full job done. Dont stroke though. No need for it.. the 300's have more than enough torque as is. (they are already a stroked 250x).

Also get a 400ex stock carb off of e-bay to go with the conversion. They are perfect for the 330cc, and cheap to boot.
