I have 2 of these excellent bikes, used on the street because of their weigh. An excellent street bike.
A couple of pointers after reasding some posts.
The KLX and KLR engines are quite different. The only common component is the carb!
A Dyno jet stage 2 kit is the way to go and get rid of the stock exhaust first
Big Gun used to make an exhaust system, unfortunatly no longer available. I think the suppertrap is crap. Thrown one out. There is a firm in UK that makes an excellent, complete stainless steel system. I could pass on the info, but costs about $600. I have one and intend to get another.
Megacycle cams do 3 cam profiles up to full race. The middle profile is probably the best all round power improvement. All this should put you up to about 60 bhp, maybe more.
JW pistons do a 10.5 cr forged piston. I am just fitting one and replacing valves right now.
I used to have a KLR 650, then I bought a KLX...sold the KLR and bought another KLX (my wife rides them as well)
Regards,
Brian

thanks for the info, i have a fcr 39 mm flatslide carb to go on it.
I have recently purchased a yoshi pipe for it , i am fabricating the header to be 2". i have the kibble white valves , springs and retainers. i have put a new ebc clutch kit in it, i am hoping for approx 60 hp. we will see, i have a mate doing the head etc who does alot of sidecars etc. as for the cams , i have to get my cores off to webcams , and have them ground.
i just bought a k and n air filter for it,the piston that i had purchased did not turn up, atv unlimited, nor did i get a refund. whats funny though they kept saying they were on backorder, everything else i purchased turned up with no dramas, who knows?
