Hey guys got a problem there i have a opportunity to buy a 1981 Suzuki gs 450 s when I went for my visit i tried out the bike and it was running great up and down the road but then next thing it cuts out and backfires. I tried to start it up but it wouldn't run so we left it to cool down for bit then she started again. The problem is when it gets warm it then cuts out im not an expert on bikes but i like the bike its condition in general is pretty dam good its just that problem there is a few things ive guessed it could be starter coil pack,letting in rich juice or possibly the floats or needles into the carb being bent or have some debris on them or possibly the sparkies but they are only 6 months old but then again its been sat outdoors for a while any ideas would be good. its a twin and has normal air box no k,ns it starts great runs great just cuts out say 5 mins of riding or just ticking over simple fix or serious? cheers dave.
