86 Harley FXRS Problems

[Justin32]

I have an 86 fxrs, and this is what I have going wrong, 120 cc in front cyclinder, and 90 in the back, I also have a ticking sound, maybe a broken spring, and the air blows out threw the carb when u first twist the trottle. Any looking for help on what u might think causes this, and where to buy the best parts for driveability, dependability. Thank from Justin

Did you just get this bike or have you had it awhile?Any history to engine work etc. The clicking could be bent push rod,lifter bearing gone bad, or problem in head. Hard to say.

Could be a bent valve, pull the heads off
