hey i was jsut wondering has anyone here built up their KLX yet, im talking not exterior mods but cam jobs, port and polish jobs, carb swap/tuning, fabrication, etc.

I was readig up on these little honeys and was kinda disappointed to hear they only push 18 HP. then i also read ona site that i moronically forgot about team green building theirs up to ge pushing about 34HP.

SO i got to thiking , if you added a muzzy full sytem, removed airbox snorkle, and rejet the carb. how much estimated HP would this turn out?

 

Also does anyone know of a location to purchase a BAMF exhaust like this one?

 

Maybe two to three HP ...F

 

that is di****able,lol

oh well, any idea on say mabe +10HP?[sm=feedback.gif]

 

just removin the backfire screen and airbox lid alone gets ya 1.5 ponies..................

 

The closest one here to 30 hp would have to be NoBrakes and that's with 81CC's of overbore and a pumper carb, and I'm not too sure if even that it would be at 30hp. I think the stock 300 which has more aggressive timing is in the low to mid 20's. I saw it in a dirtbike article comparing the XR250, DR250, and the KLX 300.

 

I think it can be done as it seems the motor in the KLX shares a lot of capability with it's brethren.

Compression, cam timing and flow will always make a motor delivery more power.

The question is, just how much do you need?

With the "Grapevine Mod Package" in, the bike does become a lot more rider friendly. According to the dyno runs I've seen, your talking about a 25 to 30 % improvement for not much money.

Might want to give it a try.

Raw power is not the only thing that makes an off road bike. Suspension is a big part of it and the KLX is spot on there.

 

In addition to what others have said, it doesn't take a whole lot. A few HP doesn't sound like a lot, but when you only start with 17, you can really feel the difference with adding a few more.
