Good morning all
Last nights practice was cancelled due to bad weather / rain so we all had a well earned evening off.
However - yesterday was most exciting as the boys took the race bike along with engine no 3 up to Slick Bass to have it run in on the dyno and then put through its paces.
The results are brilliant and I am very pleased with my engine tuning work - porting all done by my own fair hands and the rest of it by friends like Gary who shortened the piston skirt and cut a slot in the piston and the barrel to create a boost port.
The engine produces a healthy 29.8 (so lets call it 30 eh!) BHP at 8,000 revs. Compared to engine no 1 which is our benchmark - it is making about the same power and at 750 less revs (important) with a whopping 7BHP more in the mid range just where it counts! Comparing the Dyno graphs is fascinating and engine no 3 should be a massive improvement for places like the mountain mile where its all about torque. So - combine these characteristics with our ex works close ration gearbox and we should have a real step change in this little bikes ability.
So - this morning the sun shines and let's see if practice goes ahead and what we can do this evening.
