200 HP Chase Begins .... Now Completed 14 Months In. WooHoo !!

Just a guess here, as I have not "yet" got that far into one of these engines. It looks like you use a good amount of lube on the cam bearings, and even have a smear on the tappets. Maybe if you assembled completely dry, took measurements, got the right shims to make everything happy, THEN assemble with all the lube, and check no more. Just sayin.

I'll tell Scott that he's being paged

The clutch is back in.

The shim clearance has become a problem. Every time I take the cams out to redo a few shims I get totally different clearances all through the valves.
I have done this 5 times now.
This is very frustrating. Why do I get different clearance numbers when I reinstall the cams ? How do I get it right and keep it right ?

I must ask are you using over the shim buckets like stock or have you switched to the busa stuff? And are you just performing the shimming or is this with the chain on ?

 

[Neville Lush]

Are you measuring the clearance at the exact bottom of the base circle of each cam? Do you have the cam ladder bolted on?

Measuring with cam at bottom with tips facing directly away from stock shim over bucket. Chain on. Cam ladder bolted to procedure described in book.

Here is the video of the moving valve clearances.

I need some instruction guys. I have installed the manual cam chain tensioner from NLR.

What is the correct procedure for tightening the cam chain with this manual tensioner ?

How do I know it is at the correct tension and not too tight or too loose ?

 

[idk]

If it's too loose it rattles. If it's too tight it breaks.
Happy to help.

go 1/16 with wrench, 1 or 2 flats and lock down,

Not sure what one or 2 flats means?

Not sure what one or 2 flats means?

The flat on the nut, 6 flats i belive on this nut makes one complete turn and that would be too tight after snugging up finger tight, tomorrow i will take a picture of NLT
