Looking sharp. [smiley=thumbup.gif]

Regarding your -and other owners- change out of hardware to SS cap screws or other nut n' bolt materials; many of the BMW hardware bits have specific length, non-threaded shanks. These shanks are designed to be load bearing. Replacing them with hardware which has threads within the loaded area is not a good idea. The products so bonded can move a bit during operations due to the less than specified tolerances.

Engine, brake and chassis -all have some bolts or screws that must be load bearing. Performance and safety may be degraded by incorrect hardware. Be sure. Be safe.

Good advice Monte, I am now at the point of nut/bolt selection in the re-assembly and will be taking no chances!

Did the tube seals and o rings on the heads today. used a couple of skewers to compress the rings worked a charm. Cleaned up the heads and checked the bores etc

I've finally received my frame and various other bits back from the powdercoaters and quite happy with the results. Will touch up the bmw logo on the top cover with some silver paint. Now I can start the rebuild!

this may be completely un-needed advice, in which case I apologize for wasting your time but I remembered something in the course of assembling my own heads yesterday that has been a cause of grief for many.
 
Your rocker shafts need to go on such that the punch marked end is upper most in order that the oil feed via the upper studs can lubricate the needle rollers.

If your engine has not run for some time, you should move the rocker shaft down about half the length of the rollers and oil them up so that they are adequately pre-lubed, it is also a good idea to ensure that the oil feed is working as soon as possible after first start.

And, if like me, you have a momentary lapse of concentration whilst applying the start up lubrication and end up with needle rollers all over your work bench. A clean plastic lid  with a small quantity of lithium grease smeared in it is the go - after you wash the rollers in solvent put them on the grease smeared lid and work them round a bit, you only need a hint of grease on the rollers and they will stay in lace as you laboriously put them all back in the race.
 
To anyone wondering, you have the right number of rollers in the bearing when there is a little bit more than one roller's worth of space left, in other words you could put one more in, but not two - that is the way they are designed.

I followed a youtube video by chris harris for replacing pushrod tube seals and setting valves torquing heads and adjusting rocker arms etc. Didn't remove the rocker shafts so oil is still present and checked this by measuring the play in the rockers once tensioned by pushing up and down on the rocker to see the oil squeeze out at the top and bottom. But thanks for the advice

Hi Adrian thanks for the kind words, I have a bit of an update today after a bit too much pondering I started the rebuild! Slow going for me as I wanted to make sure I was setting everything correctly but it almost looks like a bike again instead of a box of parts. To everyone on here that is following I would like to say thank you as it has given me a bit of a boost.

Plenty of folks would still be sitting around looking at a naked frame and drinking beer!  Putting even little bits back on is a huge step forward.  I like the rear turn signals.

That garage looks mighty comfy  ;)

You might find the handling a little too lively now that you have pushed the fork tubes up through the top yoke by that much.  You will have shortened your rake and trail.

It might be better to mount those clip-ons under the yoke and have the tops of you fork stations flush with the top surface of your top yoke, unless you have done something with your fork internals.

Let us know how you get on.

Cheers

May have the steering responses of a trials bike. Should be fun at speed.

Hello buddy,

I saw you got a different fuel tank on your R65. I have a 1980 model R65 (dual shock version), but just canīt "plug n play" fuel tanks from other models, like R75 o R80

How did you manage to fit it there? Did you do any MOD for the tank?

Hi Dong,
As far as I am aware my tank is the original tank for my R65. Its got a bail type mount which locks around the backbone tube and is not bolted in as such. All my relays and plugs etc sit neatly underneath.
