Rite I know this subject has been done to death but I couldn't find anything that described what's going on with mine

Changed my solinoid as it packed up a few weeks ago and all was well

Went out the other nite and the bike wouldn't start when I stoped for a ciggy .jiggled the solenoid wires under the seat and all was well started off the switch .

Gave it a bit of a hammering when I got home it was a but tappy but I've read the rotax lumps do get a bit tappy when hot tried to tighten the solinoid wires but they were tight ,put it in the garage . Next morning I tried to start it and the engine wouldn't reach top dead centre stopped short and killed the solenoid. pulled the plugs out and shorted the solenoid And it spins over fine. Ploughs back in and the plier tips shorting the solenoid actually glow but it won't turn over . Battery is fine acording to the optimiser and have stuck some jump leads on aswell . Any ideas would be massively appreciated cheers james
 
Two possibilities come to mind that would be worth looking into.

  1. The cable connection at the starter motor can corrode and become resistive. Be careful when working with this connection so as not to spin the terminal stud and break the connection inside the motor. While you have the cable off, see item #2.
  2. The battery cables themselves, as well as the cable to the starter have been known to have terminal lugs that are poorly crimped. The electrical connection between the copper conductors and the lugs themselves is poor and becomes resistive and/or intermittent.



In both cases, excessive voltage is dropped across these resistive connections rather than across the starter motor where the power needs to be. The starter motor is robbed of the voltage it needs, and thus the current through the windings is insufficient to do the work at hand. It is enough to heat things up, but not enough to crank the engine over.

Do a search on starter motor issues and you'll find the details of it's construction.
