Greetings.
I have an '85 Vmax, with a '96 engine, kerker 4-2-1 exhaust (I think), and Stage 7 kit with alloy tubes replacing the V-boost.
It starts easy, runs smooth, pulls fantastically through the revs and gears.
However, if I gun it hard, after it pulls like a freight train and I back it off at (around ) the speed limit, there is a (huge) flat spot when I go to put the power down again. This goes away after a short while, and is fine if I open it up again immediately.
I have changed the fuel filter, checked the fuel tank vent (OK).
Fuel lines are a soft grey rubber (stock I think).
I am suspecting the fuel pump, which operates, but as I have read here that does not mean a lot.
If I ride quietly, no issue at all.
I have waited 10 years for a V-max, and well worth the wait!
Solder wire fix was essential, as well as the earth wire mod.
15w oil and no air in the forks help, but new (progressive?) springs are next
Many thanks for the heads up in those areas..
Help? :ummm:
