Finally got the bike back today, a week of snow and ice delayed the test ride by the dealer but I also decided to fit the kawi vacuum valve springs after they'd finished 80% of the work (customers always right though, eh?) and were waiting to take it out so they had to do a little rework.

Better late than never though cos it rides plus sounds incredible and must admit I scared myself silly a few times testing out the new setup despite the rain (no snow/ice this week at least).

Thanks again Don for the great job.

For anyone interested in the setup, I was surprised to find that they didn't need to increase the main jets at all. The dealer said that the SM+AM's actually come out the factory tuned a little rich (which contradicts almost everything I've read on these and the other forums but what do I know, he did say the new Bonnies are lean out of the box though) and that by swapping in the Thruxton needles and shimming that was enough to compensate for the mods to the pipes and the belmouth/K&N.

Anyway, 10/10 to Don. I recommend his work to anyone
