So well at least its starting to look like a motorcycle again. Im currently waiting for a new cam shaft to arrive, so while im waiting i might as well put some of the steering head and forks back together.

I put new tapered bearings in the steering and it feels great, very very smooth. New risers and to be honest im super happy how its starting to look. nice and clean. Cant go wrong with black on black

I bought some new Renthal bars (silver to break up all the black) and could not resist putting them on and start making motorbike noises!!! braap! braap! braap!

Ok so i need some advice please.

I am not sure how to install the cam chain tensioner, perhaps im over thinking it. im not sure how tight it needs to be.

so i just screwed the smaller one all the way in.
please have a close look at the pic, you will see what i have done. what is the general rule when installing these cam chain tensioners.

Any help would be great, thankyou in advance.

The smallest part in the very center is a floating rod.  The 10mm nut outside of it is the adjuster.  The big nut is the lock nut.  You're not going to over tighten the 10mm to start, but when the bike is running you adjust it until the floating rod bounces 1 - 2mm.

Hi miller , that's great thanks for the info.
When you say "bounces" do you mean it will twist back and forth 1-2mm?  And then I just adjust the 10mm nut either in or out until the rod does this?

When the motor is running, the center rod bounces in and out like a sewing needle.  If it's loose enough, it almost looks like it's going to shoot out.  So, you're adjusting until it protrudes no more than 2mm.  You can stick a wrench over it and it will tap the wrench.

Ok here is todays update:
I installed a new upgraded oil line today, its suppose to feed more oil directly to the rocker arms.

I set the valves at:
Inlet valve: 0.09mm
Exhaust: 0.15mm

(Instructions from the oil line packaging say that because the engine will be cooler. Exhaust should be 0.12mm but i dont have a 0.12 feeler guage. mine skips from .10-.15)

If anyone has any thoughts on these valve clearance settings please let me know.

(ignore the gasket silicon, when it dries i will be pulling the excess off)
