Hurricane left running
« on: October 08, 2017, 08:12:07 AM »
I started one of my bikes and got side tracked and left it ticking over l realised nearly two hours later it had stopped but wasn't siezed l charged the battery put in new plugs and it started but smokes a lot more than it did before what damage if any do you think I may have done it wouldn't have just stopped as it has a fast tick over so it definitely got hot thanks very much
Kind regards
Alan John

My guess is that you were just short of seizure, and probably damaged the rings and bore. You'd probably find on dis-assemly excessive clearance between the rings and the cylinder, and noticeable scoring on the pistons and cylinder.

It may have gotten hot, but it could be simpler.  Many bikes don't generate enough current to keep up with ignition use until 2000 rpm or higher, especially older bikes. The Bridgestone 175s have notoriously poor charging systems, so check compression before getting too worried. Depending on the state of your battery, it may have just gotten low on voltage and no longer fired the plugs well enough. The excess smoking is curious as overheating a 2-stroke shouldn't make it smoke any extra unless it got so hot (into the 400+ range) it damaged the right side rotary valve center seal and pulls oil from the transmission.
