Brilliant job Phil, have you taken it for a quick run up the road yet prior to it being completed?

Actually just back in after a 25 mile round trip to a local bike meet Mark. Its on full advance as per initial Boyer set up instructions as rev counter not back yet (as per previous post) as needs to be timed at 4000 rpm - so accelerates quite cleanly but towards end of the ride was popping at low revs/tickover on over run. Need to check the plugs for colour tomorrow. Also need to stick a bit more heat proof barrier on the fairing sides as its getting hotter than I would like. Otherwise, suprisingly little to adjust.
Handles better than I expected - front end miles more solid than my standard K2 (just on second hand progressive springs)
Biggest problem was my full face helmet - had to push my head constantly up to avoid looking at the top lip of the face aperture!

that is a fantastic job mate.  i bet the neighbours were pleased....

Its not that loud with the K0 baffles in actually - just 'throaty'

They do ride surprisingly well, can only be the weight loss and firmer suspension I guess,  you’ll find it’s limitations on bumpy corners as obviously the suspension is primitive compared to modern bikes, simple fix though, avoid bumpy corners! but I was amazed how planted mine feels on reasonable road surfaces
You and I both on the crackling and popping on overrun, mines gotten really bad of late, I’ve checked for air leaks on the inlet rubbers, they seem fine, I’ll have the carbs off this week and check the primary circuits are clear, after that it’s maybe my 40 year old Piranaha unit or maybe exhaust valves?, anyway I need to give it a dose of looking at.
PS are you fed up with having to answer the “did you build it yourself mate?” question yet?
PPS if you don’t want to shell out for a new helmet you could always have you eyes lowered!

Mark, ref the forks on bumpy bends, Andy from Goodbits (he is a member on here) does cartridge emulators which I might have a go at next year

Could well be worth fitting, basically as far as I can tell the damping just gets overwhelmed over a series of small bumps at speed, had a hairy moment at the TT when I came into a bend a bit fast (it was a tighter bend than it initially looked) and basically I just bounced around it, got very close to the kerb but got away with it (more luck than judgement), tbh I don’t usually ride mine very quickly it’s more show than go!.

Well I set today aside to fix the crackling/popping, took it for a ride to remind myself of how bad it was and guess what it’s running fine, no idea why but not arguing!, I’m going to the Norton burn out on it tomorrow at the Norton factory so no doubt it’ll start playing up again on the way there!, does anyone have any ideas as to what the issue is/could have been?
PS took this out for a test ride yesterday, great handling, brakes but just not quite impressive enough on power to warrant the 25k in my opinion (and I haven’t got 25k to burn of course), it’s unbelievably loud with those open megas, like setting car alarms off loud!
