Hello peoples.. I have a question.. I have a Yamaha SRX250, 1985.. After dropping it off at a mates for a welding repair (exhaust) for a couple of days, when picking it up it wouldn't start... the reason was a stupid little connection to the petcock that had come loose. Anyhow, until we saw that we cranked it and cranked, cleand the sparkplug, adde etho to the carb.. etc. Flattened the battery. My friend is a car mechanic, he has one of those super starter packs that will literally jumpstart a truck. I thought, 12v.. she'll beorright.. Tried ,tried, tried.. Oh sh.. whats that.. connect ..Start!! Rode home. Stopped to fuel up, and when I restarted it.. the starter motor made a horrible whining "im dying" noise. It still started, but it took a lot of convincing.. Next morning.. same. Thinking I cooked the starter motor, I subsequently battled for two days with an allen bolt off another bike skeleton (same model.. for parts) i have so I could swap the starter motor.(the donor was working fine) Put it up.. same horrible noise. Its like it has not enough crank to start the bike, and it takes ages to do it. Im afraid Ill end up killing the battery!! Im going to try swapping the starter solenoid, I think I have an old one in my shed.. if not.. can I just get one of repco, supercheap, etc? Yamaha quoted 140 bucks + 2 weeks. One wrecker said 40-50 another one 10-20. Apparently they are like 20-30 new (an automotive one), so that would look like the better choice.. The solenoid on the bike just says HItachi 12 v..
