Norton Rigid 1936 ES2

Bit of carb action which is a sort of side project, not sure if this will end being sold or make it on to the Norton, I know its a race carb without any idle circuit so much like the GP carb which is also on the list time will tell.. first up is a good clean and install a trumpet.

It still has a little bit of work to be done mounting the trumpet but it just looks so cool to my eyes and could not be simpler in design.

Not sure if it will end up on the Norton but time will tell.
 
So when I bought this bike back last April the seller told me it was an ex race bike and had a speedway crank..... so move forward to the bike rebuild and the engine had always had a bit of a habit with smoking so it seemed a good idea to get it checked out enter stage left Andy Savage , several months went buy till my engine reached the top of the
list bit later than expected but no worries. I had been in touch a few times and we had hatched a bit of a plan without knowing what lurked below...so I found a GP2 carb and my Mag was to be sent off for a check and refurb as required we also discussed the float bowl and went with a SU top and a machined bowl.


Later that week I get a phone call that the engine is stripped and wow yes a special crank, aluminium conrod, lightened valve gear, ported head Andy was well impressed by the quality of the parts used and the standard of workmanship - so I was a happy camper. The offending smoke problem looked to have been the piston which was a 2 ring without an oil control ring possibly JAP in origin.
This will now be replaced with a Forged Manx oversized to match the 80mm bore. The crank is currently being balances to match the new piston then built back up with a bore hone and some other tweaks, hoping to pick this up early March so getting excited....
 
Had a great day picking up the engine from Andy Savage following a rebuild, throw the kitchen sink at it...
Sounds like the engine was in really good shape with a host of mods already carried out including a special crank with ali conrod, lightened valve gear.
The main reason for getting the engine rebuilt was is smoked fairly heavily this turned out to be a JAP piston with 2 rings and no oil control ring.....
Its now been fitted with a forged Omega Manx piston the barrel has been bore and honed, new ali pushrod tubes, SS inlet manifold, GP2 carb and rebuilt Mag.
This should get the juices flowing this year with track days and some sprints planned.
Hoping to get the engine back in the frame this weekend and sort out throttle cables and sundries.

 
Very cool !

Just needs some exhaust wrapping, a low canvass saddle bag, and a brown seat and you’ll be bang on trend!

(Last sentence was a joke BTW...)
 
Sun out on Sunday time to break out the painted petrol & oil tank, still plenty to do......



 
Might just be me but the tank seems to have a forward slope on it?
I had to mount some spacers under the front of my 16H tank to get it to sit horizontal.
