Are there any electrical issues with the XR600R?
There’s an old saying that 99% of carburettor problems are electrical, but the XR600R’s ignition system is largely bulletproof (although pre-’88 models apparently had some stator issues).
What should idle speed be on Honda XR600R?
Honda specifies an idle speed of 1300rpm (plus or minus 100rpm) but that’s probably a little on the high side. It’s all a bit academic unless you’re using a tacho, but adjusting by ear generally works out fine (too high or too low should be obvious, you’re aiming for a consistently smooth idle where you can still tell it’s a big thumper).
Why is my Honda XR650R engine leaking?
The answer is two-fold: 1) the motorcycle had an incomplete “uncorking” job with a partial “Honda Power-Up Kit” installed and 2) a leaking aftermarket air filter had seeped abrasive dirt into the air stream and through the engine’s intake system.
What causes Honda XR650R engine to Pitt?

How old is the 1990 XR600R adventure rider?
The 1990 has been well maintained since new but thrashed pretty hard and has never had any motor work other than clutch plates and stator. Even drowned it in a river about 8 years ago but just did 7 oil changes to get the water out.
