The DR650 thread

Hoe lyk dit nou!

Die thread is maar stil!

cam chain, is there a way to measure to determine if still in spec?

Heard a slight tapping/slapping sound and thought it was my cam chain, but after inspection the guides, sprockets and chain seems to be in perfect condition.

Are your valve clearances in spec.....when engine is cold?

yes, checked those, all in spec.

sound is there cold and warm

I've had a slapping sound from 'Piston Slap' on a bike before but that normally gets better when the bike warms up.

Is there an automatic decompression setup on the DR650 cam. Wonder if that doesn't have anything to do with it.

Took the head off last night, and inspected the barrel, not even scuff marks, so would have seen signs if piston slap was present

Look, I'm no boffin on these DR650's but from what I understand, they have a nicasil barrel and piston wear isn't in the common problem list. What is the mileage?

I had a Honda Dominator many moons back that developed a clicking sound. Turned out to be the valve seat had come out of the Cylinder head and was making the noise. Maybe check how solid your valve seats are still....if the head is still off.

head came off to replace the valve stem seals, so the valves will be checked.

Well the bike is apart now so you can't do this now but what helps to locate an issue is put the tip of the screw driver to different parts of the engine and the other end to your ear, kinda like a stethoscope. This helps to localize the noise and give you a better indication where to look.

still think it might be the chain, looks can be deceiving, but a measurement never lies.

Maybe you should make sure your cam chain tensioner is working correctly. I know on the early DRZ's, there were issues where the tensioner was not long enough so the chain would stretch to a point, still within service limit but just past the extension of the cam chain tensioner and then the cam chain would become loose and a problem.

Google it or contact Lecap to see if it's a problem.

I imported a 25l Acerbis tank for my DR, but it only fits on 92 to 95DRs, not my 91. Anyone interested in it?

[Matie spero]

Good to hear from you Matie!

Is there not a balancer shaft, that is chain driven?

Kilometers on your DR?

Mooibly!

Hi Chopper, been a while!

not that I am aware off, will check.

I see there's copper or copper plated washers on the 4 bolts that tightens the head.

do you replace these or can they be reused, could not really see any crushing of deformation, but I have this idea that you always replace copper washers?

It pains me that after all these years you still do not know that there are almost no similarities between your DR and the later DR650's. Yours is basically a 80's DR600 with increased capacity.

Hey guys,
Long time since I've been on the thread, my accident damaged DR650 is still available, looking for R10k for the complete bike.
Cheers,

I'll replace them if engine not assembled yet.

Your local brake & clutch should have them in stock for cheap.

Sommer get some sump washer (alu) while you are there.
