Boy, I got here just in time.... 8)

(great pics, BTW)

First, where is your manual? It should tell you that the paint mark on the bolt is supposed to line up with the small groove in the threaded hole...at the 3:00 position.

That is TDC for the piston on either the compression or the exhaust stroke. Now you gotta find when both sets of valves are completely closed....

So watch when the intake valves open (piston going down) and then close. When the intake valves close the piston will start going up on the compression stroke....now, line up the paint mark at 3:00 and adjust your valves...

See, what I mean about shortcuts?

Okay, here's the "rest of the story...."

The paint mark and the groove in the hole are for tune ups and regular maintenance. You see them at the red arrow.

With the case removed, there is another mark for TDC. This is located on the top of the rotor and lines up with a "V" shape that is cast in the crankcase (kinda silly that the blue arrow covers part of it...what can I say?).

copy greg thanks, thats what i figured. im having a bit of trouble squeezing all the tools into place, but i imagine with a bit of finesse i can get in there. now the screw should be tight with the .005 feeler before i snug up the bolt correct? im having to jam it in there pretty hard now. the diffrence between .003-.005 is hardly even noticeable on the feelers themselves.

Yeah, it might have been nice if the engineers had made that cover a bit bigger so you could actually see and work in there at the same time...plus getting the tools around the frame. But you're on the right track, and with patience you won't have to do this for a long time to come.

success! i think. lol

it sounds lots smoother, i can only hear the tick if i try too. idle is fine as well.

its still cutting out after idling for a while or if i try to give it gas. then it wont restart unless you let it sit for about 5-10 mins, then it will do the same thing.

hmmm. any ideas? check out this pic here of my diaphram slide. that doesnt look normal to me.

You officially have a galled carb slide. THAT is why I run two stroke oil in every tank. Don't know why it works, but it works. Polish it with a filthy dollar bill, reinstall, and add some oil to the gas. Will work for awhile while you wait on the new slide to arrive.

lol, quite an interesting fix. any suggestions on a place to order a new slide? also do you think this could be the cause of my bike cutting out after a few mins of idling?

Try BikeBandit or RonAyers. Or the dealership if need be (choice of last resort).

Odds are the slide was causing the problems. It's pretty common to the Japanese bikes. Even the mechanical slides will gall and stick. Angry

Sure wish regular carbs were still made for motorcycles. You know, like a Weber sidedraft without a slide system...

It can't be THAT hard to fit a 240Z carb...

How deep are the marks in the slide? Picture is just a bit fuzzy.

I guess I'm thinking along the same lines as Greg - that doesn't look bad enough to worry about to me - I guess I consider the black coating as sacrifical - on the mikunis I have when the slide was dragging it has acted different than you describe - normally hangs on the way down, doesn't close the main jet at ldle to mid throttle and floods the devil out of the engine - good cleaning of the slide and bore take care it - I use electric contact cleaner and a clean clean rag to do it

But you describe an engine happily at idle that just dies and will not start for 5-10 minutes - I might pull the air box to carb intake tube so I could watch the slide and see if the slide is acting correct.
