carb feels like it surges - help...

[Edmund Rowe]

Good people: First I want to say this is a great group! I got plenty of helpful information to my questions that have helped this newbie a lot. My KLR 650 is less than one week old and it s my first motorcycle ever. As I suspected when I first looked into them, I may get something in addition to this KLR someday but I don t plan on replacing it with another bike. Thank God I took (and passed) that MSF class that made me a much smarter rider. Okay now on to my questions: 1) What octane gas do y all recommend? I think 89 will work in it but lower octanes may cause pinging and higher octanes cause more carbon buildup. I was thinking of 92 octane for the first fillup. Which leads to my next question: 2) Anything wrong with using fuel additives? Like the STP fuel injector cleaner stuff that you put in every other tank? I would look up my owner s manual but the dealer still has to ship that to me. Edmund sends [Non-text portions of this message have been removed]

I applaud your enthusiasm and excitement about the KLR. Remember that the KLR is a very "Simple bike". It was made to run on 87 octane. That's just 1, of the hundreds of reasons I love them. You don't need to run more expensive fuel in them, like most other bikes. It won't, and you won't, notice a difference. Except your wallet will, and these days, it REALLY will. I personally don't see the reason to run STP either. To help keep the carb and tank clean, ride the bike almost every single day, park it full of gas when you can, and if you must park it for more than a month, I would use gas treatment, or drain the whole system. I'm just guessing here, but you sound like your going to take really good care of this bike that you just bought. MrMoose A8 (Barbie and Ken special)

Sounds like you need to give it some more throttle.. Or go to a lower gear.. The KLR will lugg along at low rpm's, sometimes caused by the auto decompression thingy.. When that happens, you need to shift down, and give it some juice.. MotorMark KLR650 A13 Warthogg XR250r superfly Stone Mountain, Ga www.angelfire.com/mo/motormark
