checking valves at 500 mile first service

[gwtexas]

Been considering doing some performance upgrades to my KLR such as airbox, exhaust, etc. I don't really have a big need for more power, it's just one of those "better to have it and not need it" sort of things for me. My questions are: 1) How much power do i stand to gain with these sort of modifications? 2)Are there any negtive side effects? 3)Are the modifications worth the expense? Thanks, Greg

My Opinion... 1. Not much 2. Poor MPG 3. Its your money Dooden A15 Green Ape

Mine has airbox screen removed, airbox inlet snorkel removed, 160 main jet, No Toil Air filter For convenience- no reason to believe it improves performance) which has provided a small improvement in acceleration and increased the useable RPM range. It now revs nicely to 7,500 RPM. Mileage seems about 5% or a bit less but hard to tell exactly as I use the increased power so that will drop mileage more than if it was run at the same acceleration as before. Steady state running on highway seems not to have dropped mileage as much but I don't do a lot of that so can't be sure.

>2)Are there any negative side effects?

Not at the modification level my bike has.

>3)Are the modifications worth the expense?

Comparing mine to a couple of KLR's with after market exhausts, mine is faster but a sample of two is questionable at best. Mine pulls dead stock KLR's quite noticeably from 3,000 RPM and up. It would pull one with after market exhaust before the mods. IMO the after market exhausts just make more noise which just annoys people. We definitely don't need more people down on bikes! It is hard to quantify alleged performance improvements because most have not done any comparisons but go by the "noisier is more powerful" school of thought. According to some posts here, doing the after market exhaust properly, including proper jetting, can provide some improvement. IMO if you really need/want more power the big bore kit sounds attractive but keep in mind that you are whipping a very sick horse............ Might be far better to buy an different bike to ride when you need the extra power. Norm [Non-text portions of this message have been removed]

Dooden nailed it, IMHO. About the only mod I've heard of that doesn't wreck your mileage is drilling the slide to help the throttle response. -- Blake Sobiloff http://sobiloff.typepad.com/blakeblog/> http://sobiloff.typepad.com/klr_adventure/> San Jose, CA (USA) [Non-text portions of this message have been removed]

I put in a Dyna jet kit, a Big Gun exhaust, a K&N filter. I switched back to stock on the exhaust as the Big Gun pisses people off and has no spark arrestor plus you have to repack. I changed the K&N for a Uni filter as I trust foam more. My throttle response got better with the jet kit and carb mods. But the money I spent would be better served on suspension and brake mods. You didn't buy a race bike. Criswell

I'll apologize now if this seem like I have a bad attitude. I just don't understand the big deal in having a quiet bike. At least not in my area where the HD's and Ricky Racers zip up and down my street all hours of the day and night with loud ass exhaust notes. Now granted I have yet to hear a KLR with an aftermarket exhaust but I'd be willing to bet that they are no where near as loud as the idiots in my area. I can understand if you live in a quiet area outside of town, rural type setting. but in the suburbs I'm going to crank it up. I didn't buy a bike to ride it on egg shells. Kerry Snip I switched

Kerry, I think most folks on this list would suggest that the idea is to not contribute to the overall motorcycle noise problem, especially when there is not much to be gained performance-wise by doing so. Steve SuperTrappin', but bein' sensible about it in Norman, OK. ---- Kerry Stottlemyer wrote: I'll apologize now if this seem like I have a bad attitude.

Have you considered areas that allow you to ride your bike, lets say trails that are shared with perhaps horses or close to campgrounds, and now loud bikes with no USDA spark arrestors are riding around basically pissing off other folks to have paid to camp in a relative quiet place or paid to camp where they can take horses and ride the forest roads/trails only to have bikes going by scaring the horse which they are sitting upon endangering them and the horse ? "as the idiots in my area." you said that not me, I can not understand why somebody would take a lets say HD that comes with a nice sounding exhaust IMO and put something that sounds like straight pipes on it. Same goes for the pick up trucks modified to the point its only use to driving it on the street. Nice sounding exhaust is one thing, but just loud for the sake of being loud to me is stupid. I wish my KLR had a sweet sounding exhaust with more tone and somewhat louder is ok, but megaphone window rattling loud is just noise to me. I think fines and violations for such noise are acceptable, heck I have lived places where if a LEO can hear music coming from your vehicle you are pulled over and given a ticket, who wants to hear your trunk lid rattle and shake. Same should go for vehicle exhaust noise IMHO. However I have heard a few KLR's with aftermarket pipes that had nice tone and were somewhat loud, but not ear piecing loud that maybe if my stock pipe was toast I would'nt mind installing as a replacement providing it had a approved spark arrestor. Just my thoughts, from a rural area with many places I can ride without pavement under my tires and unless I am seen, I can almost bet I am not heard either. I bought a KLR cause I planned on riding in all types of places, pavement, street, trails, swamps, forest roads, logging roads.
