kl600 head

klr650 and kl600 have any interchangeable parts, i got 86 kl 600 that needs a head, exhaust cam seems to have lost oil and scarred up cam journals and intake valves hit pistons, 600 parts seem to be hard to find. 650 head wont fit? I'm not familiar with these at all. Anyone have a head or can point me in a direction to find one or have mine fixed. I think biggest deal is cam journals in head chewed up a bit. Maybe find used 650 and bolt it in?

Thanks for any help.

These guys have repaired many oil starved KL650 heads. Call them. (Whoops, don't know what happened. Distracted posting?)

I think @Ian H in the UK has installed a KL650 engine into a KL600 frame. Click on his name & read his threads & postings. Maybe send him a PM.

I jest, but . . . glad a "cottage industry" exists, fixing grenaded KLR heads.

Realistically, the only reason for the LAST bearings in the engine to starve for oil, is a Lack of Volume in the sump!

Maybe you ought to replace piston & rings while you are that close & take a REAL Close look at the underside of the air filter box.

Dirt ingestion leads to massive Oil Consumption. Foam air filters MUST BE oiled after cleaning.

IMO, new piston & rings would triple its life expectancy. How much did the useable cylinder head cost?

Did you happen to notice the size of the tiny oil port in the cylinder head oil pipe banjo bolt? A single 1/16th inch hole! The oil inlet near the exhaust pipe is also the same Tiny Single 1/16th inch hole.

I'll suggest that you should drill the Inlet by the exhaust pipe to 2, 1/8" holes as well as the cam shaft feed 2, 1/8" holes. Drill the LH transmission feed to a single 1/8" hole.

This may slightly reduce some excess oiling of the cylinder wall & piston rings which can be partial cause of excessive oil consumption.
