Yes he did do the dyno work on my MC28, I had a shagged chain at the time and a sticky back brake, he said I would get more power by replacing the chain than any other mod!!! I had a chain on order at the time and it came a day later.
Whilst the bike was completely stock except the JHA pipes it was making a whopping 48.5 bhp, after the flywheel was added it went up to 51.5, torque also went up from 23.7 to 24.1. He reckoned I could see an increase of about 4bhp when I sorted the back brake and the chain. The curve is really quite funny, you can really see the tight spot on the chain. I am tempted to go for a ride up there just to see the difference now the chain has been replaced.
I have not set up the HRC card yet and am not sure if I am going to , only wanted it incase I loose the standard one as they are getting harder to get hold of. I dont really want to go chopping up the loom.
