Purchased a 02 1800 about 7 months ago. Bike looked/ran perfect. No issues at all. As far as I know all stock except Cobra exhaust. Well I got into a bind and borrowed some money and it was held for collateral for 2 months. My nightmare started when I picked the bike up. Fuel cap missing. Left in rain during hurricane. Got bike home and removed tank. Cleaned tank out, replaced fuel lines, changed filter, changed plugs, ran heet fuel additive for water. 3 tanks of fresh gas put through it. Bike sounds awful. Missing, backfiring, only has about half power. I jumped the fuel pump cutoff relay and only got 2.5 ounces of gas manual says 6.4. Would that be a bad fuel pump or the pressure regulator?
