yes. fitted those clear resistors, and there was still very slight bouncing, but it was much removed from that video.
Its worthy of note to those considering this that the Philips screwdriver is indeed a #2, and needs to be at least about 200mm, it also needs to have a fairly low profile shank, as I tried with a magnetic snap on one with variable heads, and that wouldnt fit down the gap!
I also tried it with a halfords pro screwdriver, which went down ok, but was so tight in the gaps that i couldnt get the angle required to get onto the screw correctly (which risks rounding it). in the end it was an el cheapo screwriver ive had for about 5-6 years which has a very narrow shank which turned out to be the perfect tool for the job, typical!
On the up-side, the bike seems much better now, it is revving much more responsively and smoothly all the way through the revs, the clutch action seems slightly smoother (that may be in the mind though?).
The idle is still very slightly lumpy, so I think I will change the plugs/oil filter/air filter/oil, and then balance the cars again, this should solve my issues I would have thought, I need to do it anyway as im not sure when it was last done.
Thanks everyone for their help, a good purchase is the carbtune, its a nice bit of kit
