Hi guys
Have a 98RMX250S and it shat itself on monday! Rode it for about 3 mins and it locked up whilst hooning down a strate. First thought was that i had siezed the top end as when i slowly pushed the kick start down it sounded a little ' grindy '. but once it had cooled down when i pushed kick start down there was still good copmpression and the ' grindy ' noise seemed to be coming from the bottom end. not a very loud noise but happens once on each cycle
So after removing spark plug and exhasut im pretty certain the top end is ok and have also drained gearbox oil and that is all clean too.
Removed fly wheel cover to check for up and down play and there is only a very tiny bit of movement. SHould this have heaps of movement if the bottom end is buggered??
I will eventtually strip it down to find the problem but thoight id ask first for some ideas first
Cheers!
