Any DR650 sexperts here?

Someone I know (me) just bought a very new (to me) DR650. There is some minor tidying up needed and the only thing "major" is the cam box leaks.

Apparently the PO had some sort of recall (?) done and it had leaked ever since. Why he never addressed it is beyond me but I have to do something about it before I start riding it....

Cam box come off in the frame or does the engine have to come out?
Looks like Yama bond.... (yes I know, he has a copy of a shop manual with the bike but I am wanting to know now....)

The box oon top of the head that also attaches to the top if the frame. It is probably the upper cam bearing/rocker shaft assymbly. Looks to be sealed with
Yamabond and it's oozing enough to be wet and stinky but not enough to make it
past the first few fins on the head.... Such a clean bike it's silly to be leaking....

It's a '03 with huge ammo box panniers, 4 gallon tank, big seat, windshield , skid plate and big rear rack.... very surprised how quick it is for a single.

Yes. You should be able to take it off while still in the bike. Just make sure you torque it properly and in the right order.

New gasket should stop the leak. No need to remove engine from frame to replace. Yamabond is not needed if installed properly, maybe only a touch on rubber half moon plug.

Check your cylinder base gasket material. Stock is paper and known to leak, fix is to install a later year metal gasket (2006 up) but you'll need to pull the cylinder off to replace. If not leaking I wouldn't mess with it but just be advised.

Check your Neutral Sending unit under the clutch cover. Many have had the screws come loose very quickly. Remove screws, clean and loctite is a permanent fix for most.

Remove your upper chain roller, especially if you plan to ride off road. These have been broken off by many leaving an ugly hole in the frame.

There is no gasket for the valve cover. Just sealant.

And my neutral light stopped working and it took me over an hour to fish all the stuff out of the motor lol. I got lucky.

Also remove the upper chain roller like he said.

Also of you want a better flowing stock header you can grind the weld inside it.

Thanks! I have done a bit of reading and it looks like the PO did the NSU and upper roller. The oil leak is nasty and needs to be fixed. I'll have the bike and shop manual tonight.

New scooter for me that will hold 2-18 packs of Bud Light Lime! Yea!!!

I agree with everything magicman said, and to clearify, use yamabond or ultra grey hi torque RTV, making sure the surfaces are clean. And again, there is no gasket, or "half moons" on the Dr
