[Shotimes] Stiff go pedal - CHEAP FIX

[Ron Porter]

I haven't looked at how many springs my '95 has on it, but the gas pedal
travel seems fine (with the old and new throttle cables). Maybe the cable
and TB mechanism need to be cleaned up a bit?

Wonder what could happen if I just removed one of the 3 springs on the
'95MTX?

Would the throttle stick open?

I think that I would like the lighter operation.
