What is this?

[Steve]

Much appreciated, Steve, but I felt it best due to my inexperience to learn how to do it the right way. I ordered the tool from RevZilla, and should only take a couple days to get here (its supposed to be nasty here tomorrow anyway), once I know what shims I have, I'll go .05mm over, and run down the street to the local shop that has the shims I need. A few other projects (cleaning the carbs, finding a way to get the god-blessed intake boots off) and she should be ready for the road (again...)

Why would you "go .05mm over"? :-k

The clearance usually decreases, meaning you will need THINNER shims.

May I suggest you read the last part of my sig and contact me accordingly.

Yeah I had a brain fart, and thought I had to go over .05mm, but its actually under. Still waiting on the valve shim tool (plus been busy with school) so I don't know what sizes I need just yet

Has anyone checked to see if the petcock he has on there is or isnt Vacuum actuated. I tried taking out the innards and using the petcock as a gravity only petcock---basically just a on/off switch for the gas. On my 79 750 this was do able without pluggin any internal holes in the petcock to prevent gas flowing when on prime---See old threads on this subject----But my petcock was too old and the seals on the switch part of the petcock wouldn't hold so I went with a new vacuum actuated Z1 petcock.

I also plugged the vacuum hose while playing around with my old petcock and from what I see of spywalkers current set up gas should flow in at least run and res both---But they would have to be manually shut off --just like a Pingel---When not running the bike to prevent overflow of the carbs

Without seeing the inside of the petcock can't tell anymore

Good Luck!!

Right here, is the smoking gun:

It be vacuum sucked like a Kirby...

The valve clearance check will be later this afternoon. How will I be able to tell what shims are in it now (i.e. are they labeled or am I going to have to borrow a set of calipers?)

The shim sizes should be labeled on the under-side, but usually a couple will have worn off. Best to have some calipers or a metric micrometer around if you can.
