took flywheel cover of all looks good in there . what do u think i should try now . i need help hear guys a bit stuck what to look at first .

Rear wheel bearings is my guess, check for play in the rear wheel as the sound could be traveling with the chain.

it happens when the bike is sitting out of gear also so its not the back wheel i don't no what to look at first think i will give lampoons a call see if they can help

A well used Beta could develop a good clutch whine. I have heard a few and owned one once. Was never a problem, but was out of the norm. I hope this is your noise. Good luck.

He states this as a scraping of gringing noise, so pull ple plug out and rotate the motor by hand with the flywheel to listen to it and what may be rough! Feel for excess play vertically and laterally in the flywheel as well. Main bearings may be in question if this noise is present with clutch in an no rotation of trans parts. Thoughts,

checked the clutch last night and the water pump also / the bike has stopped making this noise it is a whining noise and not a scrapping noise . anyway it has gone just now not sure what it was

Maybe yon noise is a wee kelpie in yer heid LOL Glad it has subsided.

Ta the noo

Check the inside of the waterpump cover to see if the impellor shaft has been touching - we had a couple with casting imperfections that needed grinding off so that the shaft didn't touch as the motor got hot. - ( Took us a while to figure it out as it came & went )
