Another Starterclutch/motor problem

[stevejinde]

Hi Folks.

Well here goes. My 1980 TSCC GS750L or GSX750 as it's known in Europe makes a loud bang when I try to start it and then the starter jams and won't turn. The starter does turn about a half tun first though.
However this so far only seems to happen when the bike is cold, because it'll let me push start it or at least turn the motor over to free the starter by rocking it forwards and backwards in 2nd gear after which the starter behaves normally. I don't seem to have this problem yet once the bikes warm.
Any ideas? Anyone had the same problem?

Yes, I have the same problem. Even after replacing the entire starter clutch minus the big gear behind it. I received a new big gear, but it was the wrong diameter. I need a 35mm if any one wants to trade for a 31mm (brand new).

I pulled out my starter motor and most of the teeth were chewed off. I pulled one out of my wife's bike, but haven't looked at its condition yet. The starter clutch snatches just about every time I start it, but I don't have to do any rocking in 2nd gear.

You'll need a rotor puller and at least replace the springs, pins, and rollers in the starter clutch.

Thanks Guys

Well I'm still checking it out however, one other thing. At the same time as it makes the bang it smokes slightly or emmits fumes from the right hand carb and the bang is from the right side, not the left where the starter sits.... Could it be a sticky Valve? But then only when the bike is really cold (Been standing overnight)???
