Ouch! Do you have any gap at all or is the bucket touching the cam?

Any possible solutions besides grinding a little material off the top of the valve stem?

Just scored two heads for 82 bucks shipped, looks like I'll have a set of heads to work some real porting work on this fall.

Smallest shim in my pack (1.20) gives just enough clearance to spin the camshaft freely.

 

[RecoilRob]

There should be a spec for installed height on the valves. Grind the end to comply then shim the springs to get their tension back to where they should be.

 

[JaredP]

That wont work

 

[RecoilRob]

That wont work

Of course it would! If the valves are sunk so far that you can't get proper clearance...besides replacing both valve and seats what other choice do you have?

 

[JaredP]

New heads, that I have coming.

Once you shave the top of the valve, you run into retainer to bucket clearance issues and the shim becomes useless. The bucket is now pushing on the retainer and you can see what problems would happen.

 

[RecoilRob]

Oh! If the bucket makes contact with the retainer....never mind.

 

[JaredP]

New heads are on the bench, valve job and port work round two.

 

[JaredP]

rear head ported polished, valve job completed. Crossing fingers that the cams will shim out.

 

[JaredP]

Got it !

 

[champer]

Awesome! Hope your engine doesn't make noises like my fresh one does

Hopefully I will find out later tomorrow. Got the engine built today after work.

 

[champer]

Nice! Good luck!

 

[JaredP]

Its in, runs. Needs some tuning. No noises, no issues *Yet

 

[JaredP]

Proof

 

[champer]

Nice work! Bike looks great. Jealous of your exhaust, both my track bikes have the older Gen1 "curve all over the place under the engine" exhaust.

 

[JaredP]

Wanna trade? I need passenger pegs back. This high mount isn't exactly A good fit for me.

 

[champer]

Love to - although neither of my cans are in very good shape.

I think Bike 1 might be high mount:

But bike 2 might have a standard mounting point:

For what it's worth, my street bike has a high mount and I just put the right side peg on with machined spacers and longer bolts.

 

[JaredP]

I may have to try that.

 

[JaredP]

I got a build thread now.
