I have a 2005 KLX250 which came with a new Kawasaki 300cc big bore kit to fit. I am planning to fit the kit and my question is does anyone know a suitable jet kit to go with the 300cc conversion, would a Dynojet Stage 2 kit for the KLX300 work ok, I would think it would but has anyone had experience with this conversion? My KLX has a Staintune pipe and the air box lid has been removed.
Any advise would be appreciated

 

The stage 2 will work fine. I was curious on your year model. Is this a U.S. model or something else? I have an '06 and installed a factory KLX 300 jug and piston. It was a great addition. It works well with aftermarket exhaust.

 

Assuming your bike runs properly now, with a lidless airbox, it probably already has the DJ2206 kit in it.

 

Its a Australian model, Seems to run OK with the lid removed but I don't know the history of it from the guy I bought it from, he bought the bike with the new kit supplied to him from the guy he bought it from. The bike has only done 3500 k/m. Paid $2600 AUD for it so with the new 300cc kit I think I had a bargain so will buy a 300cc Carby Stage 2 kit for it. Love the bike great fun on the dirt, not the best on the Hwy. But had a Yamaha Vmax before that so bound to feel the difference :-)

Thanks for the feed back
