IT LIVES!!!!
Picked up my barrels on Saturday morning (yesterday) spend 6 hours in the shed. Only the bottom end was in the frame and had to add the complete top end, mag, dyno, inner and outer primary etc and six hours later, ready to run. I spent 45 minutes spinning the motor over until I saw oil return to the tank and then gave it a prime, a kick and got a backfire. Thought to myself I may have timed it on the opposite cylinder so I swapped the leads and it started first kick, settling down into a perfect idle, no more awful bottom end noise!.
All that is left to do now is adjust the clutch and run her in!
Cheers fellas from one very happy A10 owner!!!
