Quick question. I recently rebuilt my carbs and went through the 3000 mile tune up and things were running pretty well. I decided to pull my plugs and see how they looked and I was definitely running rich. I measured the gap on the old plugs and they were at about .025 I bought new ngkd7es plugs and gapped them to .060. I had a difficult time getting it started after the plug change but once it was on the road it ran better than ever. Absolutely no hesitation and pulled hard. I only ran it a few miles and noticed while idling I was getting a little smoke out of the exhaust that I never had before.
BIke is very hard to start and if I give it any gas at all it wont start.
So I threw the old plugs back in and it fires right off, no smoke but doesn't pull as hard and the little hesitation is back.
With the old plugs I was running about 2 turns out on the mixture screws but was getting some popping when coming off the throttle hard and had a small hesitation when getting on the throttle. I went to one turn and the popping went away but the hesitation persists. I do have a couple of holes in my exhaust that could be causing the backfiring. Sorry for the novel. Any ideas are appreciated.
