SD and Gus;

You got a # for R&D?

Super;

Whats wrong with Barnetts?

[Super Dave]

I don't know it off the top of my head.  I'd google it, and you should be able to come up with it.

Well, what's wrong with the OEM ones?

I've seen the Barnetts have big adjustment problems.  Seem to expand very differently.  Maybe someone else has a better answer.  But I've had to experience the problem on the one Harley I rode, a vintage CB750 race bike, and a current production race bike that I had.  Maybe it's different now, but I have too much good luck with the OEM stuff.

I have recently tried a clutch from DP Brakes, but it's a completely different material, so I'm kind of excited to see how that works.

Well, today I got to play with it.
Thought I'd be able to split the cases and pull out the gears, but NnnOOOoooo...
In Yamaha's infanite wisdom, they decided to put 2 bolts under the # 2 & 3 cylinders.
So I had to pull the head and jugs first. Guess it was a good thing though. Cam chain seems loose, bends to the side quite a bit.

Time for an overhaul I guess. There wasn't any noise, so should I mess with main and rod bearings? Rods seem to have nominal movement.
I do think now is a good time to change the rings since it is apart and do a valve job. Any suggestions on who to go to for head work?

Thanks.

Just to let all know, PSCook sent me a tranny and a flywheel I needed.
Today I had sent off the 2 trannies to Orient X so they can do their magic.

I took my head in to the shop for a valve job, after they got it apart, I brought it back home and ported it. With my race car engine building experience, I figured it would be easy. After I was done, I took it back to the shop for them to cut the seats and finish the rest.

Now, I understand fluid and air dynamics but, from what I was told, after the fact which I did, you are not supposed to knife edge the area between the valves. Why? Yes, aircraft wings have a rounded leading edge and a sharp trailing edge. But, I believe that since I am not tying to "fly" though the air, I am directing the air. How can this be bad? Please explain.

If someone knows differently correct me, but I believe I heard it's to stop the atomized fuel from partially seperating back to a liquid state?

sorry was late posting it my mistake it was roadracer22

[resurection]

I believe the knife edge ,aims the flow and causes unwonted turbulence.
The atomised fuel responds best when the mixture is completely and smoothly enveloped around valve circumference .
More like filling room with fumes that will be sucked out when door is opened,as apposed to aiming a hosed  stream of gas into the corner.

[Ducmarc]

all the 996 style ducati heads are knife edged in the intake port and they work pretty good .

[Noidly1]

What would it be if it where extrude-honed? Round or sharp? Smooth for sure.
That's If one could even afford to have it done.
