Cheers
This is common advice on new MXers with titanium valves. Can't see how it would apply to a 1990 DR650. Is that really what it says in the factory manual?

A good valve job with modern equipment will make for a great seal without any lapping.

It can be done by loosening only one side of the triple clamp. Same for the handle bar clamps. only need to loosen one of the 2 clamps.

Thank you ProCycle.

Yes, at least my manual does. It is not "RS" specific, but for the '90-91 DR650. I confirmed with another ADVfreak with the same bike and his manual says the same. States something about leaving a soft surface and the valves will seat themselves in the first few minutes of the engine running. Strange thing is I called a dealership stateside and their book for a '90/'91 makes no mention of not using lapping compound. Dealership here says they always use lapping compound and likely never look at the book either.

Modern equipment is going to tough to find here in Costa Rica. So my dilema is to lap or not to lap ? Brand spanking new valves are OEM and I have no clue what they are made of. Also, what happens if you do lap where no lapping is required?

Your two cents and everyone's as well is always appreciated.

So, my poor DR has sat in the garage all winter. It'll start, then die after about three seconds. Used fuel stabilizer when I put it to bed. Ideas?

I doubt you could do any harm by lapping the valves. If you went crazy with the lapping compound and a drill motor you could possibly wear through the hardened coating on the valve faces. Any sensible amount of careful lapping won't hurt in any way.

I wonder if the manual actually says (or means) not to grind the valves? Since the late 60s most Japanese motorcycle valves are made in such a way that if you re-grind valve face of a used valve you will remove the hardened coating and the valve will wear out in short order.

We lap every valve in after a valve job just to confirm valve seat location and a good finish from the cutters. I doubt you could lap enough by HAND to move any material. We use mostly use a "4A" compound which is fine. We never use anything courser then a "B" which is considered medium/fine.

I have ground motorcycle valves as well with no problems. What you have to watch for is if the black hard nitriding is on the face of the valve. If so it was hardened AFTER being ground. But, if the face of the valve is not black it means the valve was hardened BEFORE the face was ground. If it is not black to begin with I go ahead and grind it. We actually grind every valve (even new) for automotive stuff. Mass produced valves are often out of round more then you would think.

I've seen the do not lap on motorcycles an foreign cars for the exact reason you stated- for seat in purposes. I can only guess why. 14 years building motors- every valve lapped- and not one leaker; so I'm going with what has worked for me.

I'm with ProCycle- Lap them boys in and start burning gas!

I can't believe someone actually was able to get that thing off. I started with a screwdriver- moved to the hand impact, moved up to the air impact, on up to the torch and air impact. At that point I decided it was there for good and I never need worry about it coming loose in an atomic blast. Decided I really didn't want it off anyway...

Yeah, no reason to remove it anyway.
