02 Aprilia sr50 odd starting problem

[skeverd]

Hello, i have an sr50 which has been running great for the past 9 months or so.

I last started the bike yesterday and let it warm up. However, today it decided not to start.

Ive gone through the usual checks - fuel, oil, spark, compression. all seem fine.

However the bike refuses to start. worse more, there is now a somewhat high pitched 'squealing' sound some the exhaust also, which only decided to start a while after trying the rectify the bikes problem.

Has anyone else experienced similar or has any ideas of the problem?

i appreciate any help available. Thanks.

squealing sometimes means bearings are knackered

the starter pinion gear hasn't got stuck or fallen off has it /?

well the engine does turn over when using the starter, where its stuck or not i'm nor sure, however the kick start doesn't start the bike either. =/

Would squealing from the bearing just start within a matter of seconds?

Also, surely the engine would still run with worn bearing? considering it was fine when i left it and now has an inability to start?

would you be able to get a video of the sound ?

what was the compression you got reading ?

ut seemed easily enough, though i only did the finger testing, yea i shall post a video tomorrow

(my old Honda seemed to have less compression when i used to do the same test and that ran fine)
