Engine Noise

Hi all, new to the forum and new to the KLR but not new to motorcycles. I'm an old guy and have been riding for 40 years including some cross country trips. I've owned over 30 motorcycles, the last being a BMW R1200RT.

I recently acquired a 2008 KLR650. I don't know much about this bike but it seems to me that it is kinda noisy at low rpms. When starting off it seems to knock some then quiets down when you get some rpms. Runs strong and otherwise seems good. Noise is only at low rpm/speed.

Is this a normal noise on the this big single or a potential problem?

Thanks in advance for any responses.

John

What oil are you running? The 2008 bikes had oil consumption issues. Since this bike sounds like it is new to you maybe the previous owner let the level get too low. Maybe it needs a doohickey adjustment. Have you looked at that.

Thank you for the response. Oil is Kawasaki 10-40 and is at the correct level. Not know the history, I will be changing oil today. Now for a dumb question....whats a Hoohicky ?

2008! Hummmmm how many miles? They used oil. Keep a close eye on the oil level.

IMHO the KLR650 isn't exactly a quiet engine at an idle, even when everything is OK. My suggestion would be to check the intake and exhaust valve clearances. If the previous owner ran the engine low on oil (not an uncommon thing), the first failure area will be the exhaust camshaft bearings. The exhaust camshaft bearings are last on the lubrication circuit. The first symptom of this type of a failure will be a noisier than normal valve clatter. Worn camshaft bearings allow the camshaft to move away (slightly) from the valves. The result sounds a lot like slightly excessive valve clearance adjustment. This clatter will seem to disapear as the engine is acceleated from an idle. Ask me how I know this!

Many times I have had scary noises at certain RPMs that ended up being loose bolts from the frame or plastics. Keep an ear out for that. And as mentioned, always check your oil consumption on an '08.

Blue loc tite is your friend., I'm making my way thru all of them on mine. On any used bike I'd check every bolt for torque, new bike too and check periodically.
