Hi Paul,It will be obvious if you've opened up the bypass holes sufficiently. You will see a clean hole which is larger than its neighbour. If the bit hasn't gone through all the way, you'll sort of have a smeared opening where the bit has not completed the cut. To check, take the drill bit in your fingers and offer it to the hole. It will slide in and out a few mil which will again be obvious to tell. Remove/fit the throttle cables with the carbs out to the side of the engine, not while they're in place in the stubs. You can balance the bank of carbs on your left knee while guiding the cables in to place. Takes me about a minute to do both using that method. Mike, is it possible to go too far and knack the carbs? I ran the drill bit around for a good minute or so but didn't push forward too much just let the drill do the work.
thanks mike. im going to take the carbs off again and check in a coupla weeks. When looking down the throats I could barely see the holes, even with glasses and good light. my old eyes aint all that now im older. ive ordered one of those LED lit magnifying glasses off ebay (along with a long reach 3mm t bar), and I figure now ive done it once getting the carbs on and off isn't such a big deal. Im also making up a template for the floats..i used a ruler with 14mm markd off but struggled to get a good line of sight in practice, so just want to recheck that too. im about 95% certain its ok, but I wanna be 100...
It was fast before, and it was good before. But now, its definitely faster, and its definitely better. God I love this bike...
