I have never had so much trouble, and some weird stuff going on.
Recent PMA failure led to reg-rec blowing and battery fry-up. So, Fixed it, and I'm on borrowed 3-phase reg-rec until Hugh's replacement gets here.
While all that was going on I tinkered with everything trying to find problem. So when I found it, I went back to square one. Checked cam chain (perfect - nearly new anyway); valve clearances (spot-on - checked and re-checked); timing (Boyer - accurate and all in order; plugs (cleaned and checked gap); in-line filter (cleaned it); wiring (checked everything, twice and more); new HT leads; checked ohms reading on plug caps (within tolerance)
Then put carbs back on - and tried to start. Only fired after many many kicks (what happened to first/second time?). And when it started it was hovering. So, checked all the above again (all in order).
Must be the carbs so took the beauties apart. Pilots 27.5 cleaned and seated correctly; same with mains (135 is a bit high, but worked for me so far); needle on position 2, floats 25mm, good gaskets; then I noticed one needle jet not tight in position - so I took off thos 76/77 BS38s and put on my 78/79 BS38s. I've got through pipes and UNIs so replaced 27.5 pilot with 30, kept main at 135, needle position 2. Mix screw 2.25 as guide; tried floats at 24 as per carb guide - didn't like that, so 25mm and bingo, fired first time.
PROBLEM - the bike does not sound right and is not running right, and I can't get it running back to it's smooth self.
SYMPTOMS - I get it running decent idle while on side stand but when I bring it up the engine stops.
TRIED SO FAR = I tried dead cylinder. Left cylinder co-operated while I tested the mix, but right cylinder just stops when I pull plug cap. Tried dropping pilot to 27.5, but started hovering (jet too small), so back to 30. Tried advancing timing, but starts to hover on the idle when I drop the rpm.
HELP! there is an solution to this problem out there - there is always an solution.
