First let me tell you what's been done. Ported heads, 10.5 to 1 pistons, stage II kit, pcm III, stock pipes with V&H slip-ons baffles cut down to about 6". The bike ran fine for about 3 months after the headsand pistons were done. Then it started to run real rich and shut off at stoplights. Took'er into harley and the said "something" was out of adjustment, bike ran a little better. Bought the pcm III had it dynoed and she ran great. Drove around for a couple months wenton atrip and 100 miles from home it started runnnig only at full throttle around 75 to 80 mph. Then at 20 miles,I could only go 50 mph pouring out black smoke. Oh it also burned a whole tank in that 100 miles. Anyone have any ideas? Thanks.
