With the dry build complete it was hopefully the final strip down finishingh off soem welding and the frame was sent out for satin black powdercoat

Next up the headstock bearings were the old ball race type like a push bike which had seen better days so we have gone all modern with a tapered races. Outer race fitted like it was made for the job.....

The swingarm was rubbed down and given a couple of coats of satin black from a trusty spary can, didn't think the bearing would like 200 degrees at the powder coaters and it was in good condition so........

Putting the engine in is a 2 man job now its all pretty, so awaiting my able assistant returning for his hols and hope to make some good progress next weekend.

As a side note finally joined facebook to see what's going on in the bike world posted a few pics on a site called "BMW 2V Boxer" and seems to have gone down well, looks like there is a drag race series called "The Sultans of Swing" and they are keen to have some new competitors so that's 2017 holidays taken care of......

So jobs to do
#fill with engine and gearbox oil y
#Add fork oil y
#fit tube and tyre + clamp + new brake shoes - well re used old ones as the new ones were not the right type y
#Fit rear brake rod + gear change rod - gear change needed to be modified and still needs a further tweak to get some adjustment y
#stand back and take a bunk of photos y
#rig up a temporary fuel tank and book the rolling road with RM - not yet

So here it is was a nice day so pushed it outside and took a few photos.....

Looking really good! The exhaust is killer!

[Dexter]

Thanks 555, can't wait to hear what is sounds like....

[Dexter]

Bit of an update of sorts as like all good projects there never finished....

Put in all the fluids and checked levels - not sure if the engine oil has gold in it but when its done in the bike may have to see if they give you a credit on return..

The wiring loom had been all laced up but remained untested and RM was keen for me to turn the engine over before any rolling road sessions which sounded and proved to be good advice.

So we jury rigged a battery up (the final one was still to be purchased at this time) by this stage we had also plumbed the oil pressure gauge, bike turned over on the starter button and after loosining the pressure line to bleed it we also had a healthy 80 psi cranking pressure. At this point the managment box was looking remarkably un interested and true to form we should have been seeing an led light flash as the crank sensor passed the trigger

Traced out the wiring and if you can believe this the kill switch which was on a lanyard so if you fall off it kill the engine... well this bugger only made a curcuit with the lanyard disconnected - needless to say this now in the bin so a couple of quick wiring alterations and bingo flashing led :0.

Been speaking to RM and now have 25L of Sonoco race fuel at almost £5 L good job its only 1/4 mile a time... still hoping to get the the RR this side of Christmas and should also have the painted tank and fairing back soon cant.....

[Dexter]

So been a bit of a break what with christmas and all but its not stopped progress, i will just leave this here........
