kientech exhaust modification

[klr600ca]

Hello, I have an '86 KLR600 and love the stupid thing. I put on a Sauppertrap EAR slipon and opened up the air box. I then put in a unifilter foam instead of the old Kaw filter and did a Dynojet kit. The bike rips now. Thing is , I don't know of any cams available aftermarket for the 600. The KLR 650 and 600 share the same exhaust cams but differ in intake cams. The two bikes share most top end bits but for the intake cam. Just wondering if anyone knows the lift and duration specs for the two bikes. Hope that the lift is a bit more on the 650 and not different in other respects. Could be a cheap upgrade for me.

There probably won't be any.

The manuals only show the cam heights, which are near enough the same. The 600 intake has a duration of 260deg, the 650 intake 268deg. Not a big difference. One day I might get around to trying out my dial indicator gauge on the head to find the actual lift. Mister_T Melbourne Australia

[...] Even a 38mm slide carb would be an improvement, if you could get it to fit above the starter motor. OTOH, an EFI throttle body would have few such limitations... Mister_T Melbourne Australia

Thanx for the input. Opening the air box and replaceing the filter with unifilter foam helped. The dynojet kit helped loads ( put the 5th gear upshift to 120kmph) the EAR exhaust and a 150 main jet took the 5th gear upshift to 140 kmph (86mph). The bike runs real hard now but more is always wanted. I just got off my monoshocked H2 750 tripple and this KLR while fun is taking some getting used to. R

Somebody wrote to the tech help section of Dirt Rider Magazine with a question about resurrecting a KLR600. This magazine is all about little bitty high-performance playbikes, and they said that the 600 was one of the best big-bore dual sports made. I forget if they had any qualifiers to that; I'll have to see if I still have the issue. Krokko -- Dr. J. Christopher Krok John Lucas Adaptive Wind Tunnel Caltech MS 205-45, Pasadena, CA 91125

Hi guys another thread I know im on a bit of a roll and perhaps I should do one job at a time!!! I have found a stage 3 dynojet kit that I am interested in fitting to my bike, I am just wondering what a good performance based exhaust would be to accompany this install as I do still really need an exhaust. Also what else could accompany these installs I am interested in acceleration as the bikes generally arent too good at high speed anyway!

Good Morning, I will just chime in with a quick observation. Don't in any way take this as a discouragement, but: The KLRs are GREAT bikes, but they are not high-performance machines. Most of the people I know, talk to, or read about eventually make the observation that KLR performance mods do not add a ton of extra "umph" and tend to kill the gas mileage. I love my KLR, and I love it even more since I've come to accept it for what it is, and what it isn't. It IS: A rugged, reliable bike capable of decent highway performance and decent off-road performance. With a couple of minor mods, you can get a LITTLE more snappiness out of it. An easy handling, safe bike with good suspension An almost perfect fire trail bike, able to run them all day without complaint An OK touring bike as long as you stick to the 2-laners. Extended stretches of interstate give you numb hands and iron butt. It IS NOT: A high-performance road bike A motocross bike A Gold Wing What I ended up doing was picking up an old Seca II for $500.00 and doing the performance mods to it. The engine, frame and suspesion of a street bike responds better to the performance mods. It only costs about 30 bucks a year for registration and my insurance only went up 9 bucks a month. These are my observations and there are quite a few others that have made the same. Whatever you decide, enjoy it. KLRs are great bikes regardless. -Jeff Khoury
