brake fluid .. dot 3 ?

[johnfzus]

Hope someone out there can give me a little insight on this. Just talked my best friend into buying a '91 klr 650. Bike only has 3800 miles and seems to be in pretty good overall shape. Bought from local Kaw dealer. the problem is when you hit the throttle hard there is a knock, knock, knock in the engine. This only last for a few seconds and then seems to go away. It happens only on hard throttle. it happpens both when you are just revving up the engine at standstill or accelerating. Not sure if "knock" is a good description of the noise or not. Took back to dealer and he said this is somewhat of a trait of a big single. He also said it could be coming from the clutch basket. {I have a DR650 and it does not have this noise} The bike runs great other than this. When under steady throttle it just purrs along. Is this something to be concerned about? Would appreciate your thoughts. John in Ohio

John, Have you checked tha balancer system? This bike has all the bad parts in the system, springs and pins driving the balancer system and thru this the waterpump. The balancer chain may be loose, too, as lots of times the lever has crimped around the bolt, the spring has no tension. Also has the early clutch gearbox system. All is easy to fix - it's a KLR Mike Eagle Mfg & Eng San Diego, Ca.

I just asked about that same noise a couple of weeks ago. I too heard that loud knock when I bought my 94 KLR with 9800 miles on it. It was in very good condition, taken care of by a mature man, and it ran very well. It is totally NORMAL. I hear that same noise on my friends bike and another friend that had one for 3 years said he remembers his doing the same thing. To clarify what noise I am talking about: It is a very distinct knock (not a ping or tick) heard low in the motor. It happens when you just blip the throttle, (about 2 or 3 knocks) or if you are just cruising along and whack open the throttle you can hear it for the next second or two. You can really hear it loud and clear when leaving a stop sign or red light as you feather out the clutch and are not giving it alot of gas. Mine has done it no matter what adjustments I make to the carb, no matter what octane fuel I put in it, and it has done it for over 3000 miles now after putting in a new doohicky and spring. My bike still runs great while flogging it all day long on twisty back roads. MrMoose A8 (Barbie and Ken special)

Yup... I agree with the description of the "knock." I've had that very slight irritation since I bought my KLR 2 years ago at just under 5k miles. I have over 25k on it now and the exact same "knock" is still there. I'm not worried about it. -NM Mark

I don't think there is any problem mixing 3 and 4. It is only the 5 (silicon based I think) you have to worry about. Criswell Barnaby Robson wrote:
