Ash and his brother Rob were a huge help all day
I needn't have worried, the noise man just laughed when I pitched up for testing. So the whole morning was written off, trying to (ahem!) tune the exhaust with baffles and lots and lots of gaffer tape....
It got quieter with each successive modification, but he still wouldn't let us out. And if I'd have run for more than a few minutes, the tape would surely have melted. However, all wee needed was the "Pass" sticker... And anyway, with so much backpressure it barely ran at all! I managed to buy a couple of new, more restrictive baffles. You can see them plugging up the cans here:
These met with his approval, but then hen the noise man tells us "Oh you were right enough, we whould have been testing at 4000rpm, not 5000"..... So I've missed the mornings test, and I'm thirty quid down.... oh well...
Ash removed the baffles for me, skilled motorcycle engineer that he is!
Anyway, after a bit of fiddling with the timing, she ran, well enough to test.
Dave Bennet took few shots, just so you know I'm not telling fibs! Check out his blog on the Yamatax he's building for Ash.
So she runs, but the carbs need a bit of fettling now. We kind of ran out of time, but managed to get an approximation of base settings for the carbs, the ignition timing and the chassis. And I am in no way to be considered a test rider...!
However, I'm very pleased about the motor. There are many people who have contributed to Friday, and I know its not even a race, and I was slow-slow-slow, but even just a test feels like a victory. So thank you to all who know who they are! Will post soon on the minor fettles before the next test at cadwell, on the 15th May, the day before Round One.
