I may do the 300 conversion later in the year. I should just be able to bolt on an EC300 cylinder with powervalve assembly, head, and piston kit without machine work, correct? Did you change the power valve governer spring or ignition module? Thanks.
I disagree to a point. I went from a 250 to a 300 this year. I stalled the 300 ALOT the first race I ran. It was very tight terrain.
Never had the problem with a 250.
I installed a non-resistor plug and kicked the idle up a 1/4 turn and NO MORE stalling!
The governer and spring can remain the same, but the main powervalve flap must be different to match the larger bore, correct? I'm just trying to research the project parts and cost at this point. Thanks.
I completely agree with bgdawg's intial post - including the SHOUTING. The GasGas 300XC is very stall resistant in stock form once you get it jetted. If you expect it to pull along at idle in gear, then you will need a larger flywheel. Overall this machine is AWESOME (intentional SHOUTING). The handling and power delivery are flat amazing.
Warning: only test ride a GasGas if you can afford to buy one or you will be disappointed when you have to go back to your other machine.
clw The xc 300 has a small flywheel and is very quick, for moto-x or harescramble and all one needs to do for tight, real tight, woods is add the flywheel for even more torque riding!!!:D
