Travis2626 Posted February 13, 2018 Report Share Posted February 13, 2018 So my 1975 ty175 will start right up after sitting for about a day but after riding it for a bit the bike will die and not start again for a few hours/overnight. If anyone has suggestions about what the problem might be it would be greatly appreciated!! Quote Link to comment Share on other sites More sharing options...
jonnyc21 Posted February 13, 2018 Report Share Posted February 13, 2018 Last time I had a problem like that it was a bad ignition coil. Could be a bad spark plug as well. good luck. Quote Link to comment Share on other sites More sharing options...

Yes a bad coil will heat up after use then tip over,plugs well I find in lawn movers ,chainsaws,scooters and ride -on mowers they don't appear to last long....a fuel quality thing,not really sure?.

lineaway Posted February 13, 2018 Report Share Posted February 13, 2018 Try a new condensor and file the points before trying anything else. 3 Quote Link to comment Share on other sites More sharing options...
jonnyc21 Posted February 13, 2018 Report Share Posted February 13, 2018 Good point, I forgot about the fact that a 75 TY175 would have points. I agree with lineaway, condenser and points then check your coil. Quote Link to comment Share on other sites More sharing options...
2stroke4stroke Posted February 13, 2018 Report Share Posted February 13, 2018 At that age the low tension coil can give trouble too. Quote Link to comment Share on other sites More sharing options...
guy53 Posted February 13, 2018 Report Share Posted February 13, 2018 Have you tried to loosen the fuel cap when it dies ? Guy 1 Quote Link to comment Share on other sites More sharing options...
Travis2626 Posted February 13, 2018 Author Report Share Posted February 13, 2018 Where is the condenser located? I just put a new ignition source and ignition coil on the bike. It has a fresh spark plug also. Quote Link to comment Share on other sites More sharing options...
section swept Posted February 14, 2018 Report Share Posted February 14, 2018 Depends where the previous owner fitted the condenser, it could be next coil or still in original position behind flywheel/mag. Check carb breather pipes not kinked, crushed or blocked. Fuel tank cap breather is this clear as guy53 suggested. Full ignition check, contact face condition (dark royal blue colour on contact faces indicates condenser ? Air filter is this clean and unrestricted/ bunged up with crap etc. Is exhaust relatively clear and not carbon loaded or oiled up. Piston is compression good and not too noisy piston slap wise, rings could be gummed up and causing running issues. At the end of the day diagnosing running faults etc is very difficult at a distance but hopefully you have enough to go at. Let us know if you sort the problem??
