If I had been more awake, that's what I would have done – only shortened the left, instead of both sides, and got more twist into the x-over installation. I've a feeling that I'll revisit this some time.
Maybe tomorrow I'l post some pictures that I took of how it all lined-up.
I only had a short test run last week and haven't had time to do any more with it it since, but I still think that it's pretty loud out on the road. The 'half lidless' air box adds a bit to the noise too.
What can I cut-up next?
Enjoy
