Ok manual says bring #1 piston to TDC , check to make sure timing mark is lined up. Why does it say to check clearance on #4 valves? I thought you check valves when piston at TDC= valves for that cylinder closed.
Valve clearance check
- Thread starter onehelipainter
- Start date
you can check 8 valves in a rotation.onehelipainter

still says nothing about checking #1 valves when #1 is at TDC

Ok, when No 1 is at TDC COMPRESSION stroke and firing, you check all 4 valves of No 1, check exhaust valves on No 3 cyl, check inlet valves on No 2 cyl
Then rotate crank 360 degrees and then check all 4 valves of No 4 cylinder, exhaust valves of No 2 cyl, and inlet valves of No 3 cyl
This sequence enables you to check all 16 valves in only 1 rotation of the crank.
This is to help you understand the best and simplest way to check valves.

Ok how do reset the Cct? This one has no bolt at
the rear.
they are over due... bike is at 60k mi last insp,was at 24kHow many km are they due at is it 45 thousand km ?
Is it ticking?
I suppose sometimes they can tighten up too...I met a guy one evening who has a copper '99 bike and had it since new, it has 125,000kms on it and he checked the valves at each required interval and has yet to need adjustment.

I was @ work in a high school fixing stuff as usual. Just made a few minutes of time to explain the quick way to measure it out.
Had to do it twice as camera couldn't see the green marker from its fist point of view.
Cam chain tensioner I believe has oil preasure driving it on the bird. Haven't had to service one yet. I'm also to tired to go crack the book open in my hot garage currently.

Every 24,000kms . . . so 48,000km is the 2nd check.How many km are they due at is it 45 thousand km ?

I will say this . . . every Busa we service from new has a full service history and very very seldom is a valve shim replacement/adjustment required.
My own Busa, with 115,000kms on it, had 3 out of 16 'borderline' clearances, on the tight side, but still within spec only just!
So they are very well set up from new and reliable through their service life, as we all know
