hi, think the engine may have seized on a friends 1998 270 gas gas. any recommendations on who could inspect,/ rebuild/repair, or where to obtain necessary parts at reasonable cost? thanks.

Its pretty easy to inspect it yourself, Drain your radiator then take the four bolts off joining the head to the engine and the part on top of the cylinder joining it to the frame, disconnect the water pipe from the top and pull the cylinder off, you may also need to remove your fan and radiator or just move them up in the frame. If your lucky you may just need new piston rings (about

thanks heathy. not sure on how it seized or why, the engine just died. when we tried to fire it up, it was very hard to kick over, and sounded growly. Any ideas on who does the re-chroming? (we are in south yorkshire)

My one nipped up on the SSDT last week and went out for re-chroming today. See here http://www.trialscentral.com/forums/index.php?showtopic=4305

does the engine still turn over? take your spark plug out and try to turn it over.

hi colly. yes the engine does turn over with the plug out.

If that's the case it may not be too bad. Pull the top end and inspect for scratches/gouges in the cylinder wall and piston. I've seen lots of seized MX motors without doing any damage to the cylinder wall plating.

thanks JTT, will try and have a look next week.
