I,ll have to check how it was set up before they sent it out. Cheers

Just fitted one today, came direct from Gas Gas UK so I,m assuming its set up already for the 300, any one fitted one on a 300, mines a 2011 and had to make any setting changes. I,ve not ridden it yet so can,t say mines wrong but I can tell straight away it's gonna need some adjustment.

Hi Thanks for the advice but definatley not that simple I afraid although I wish it was.

I had another look at this bike today, the hard bit was getting to it at the back of the workshop, after all these months of it standing there it started second kick on crappy fuel, unfortunatley the noise is still there i wasn,t that lucky. I tried what you sugested on another thread , started it up , had bike on a stand in gear and held on rear brake while feeding in the clutch and the whine came in as soon as the clutch started to bite. I rode it round the garden for a bit and the whine is constant until you pull in the clutch, sounds really nice for an old bike until its under load.

Hi I,m after bar risers for a 2011 300 Pro, just wondered whats available, i,ve seen the S3 type but they don,t look like they raise them that much and being 6ft 3" i want to notice the differance, the clamps are the hinged type so most of the mx one,s won,t fit by the looks of it.

I need a new silencer for a 2010 280, what aftermarket silencers are there available, genuine prices are over

I know its some time sinse i posted this thread but i,ve only just had the time to get my hands back on this engine for another look and i,d like to sort it once and for all now, i havn,t tried the above yet but took clutch cover off for another inspection, primary gears clutch and kickstart gear idle all have the hardening worn off but no damage appart from that. when spinning the idle gear with clutch removed it does sound noisy against the kickstart gear but weather this is magnified to the amount i can here when running under load i don,t know.

Hi I recently rebuilt a 07 gas gas 280, i had to replace the selector forks which were bent plus one gear and the kickstart ideal gear. Now the 4 gear is noisy compared to any of the others and gear selction between 4th and 5th up and down is very difficult. I,m gonna strip it down again but is there anything you would suggest i look at closly. Cheer,s Daz

Thanks for that ,i was hoping someone would say that as it,s back together now.

Just rebuilding a 280 pro 07 model, got a question , there,s two o-rings on the output shaft, do these both go in from the outside after the bearing, i know the 1.5mm one sits in the spacer but its the 2mm o-ring i,m not sure on. Any help apreciated. should have paid more attention when i pulled it appart.

Does anyone know the correct puller size for an 80cc gas gas, i think its a 19mm x 1mm but i,m not sure.

Your right about the hub type, and I,ve fitted new hub so there's no play either , the noise does seem excessive but until I here another 2000 model I,ve got nothing to compare it against, everything is working o.k so your diagnosis may be spot on. Only thing that is strange if that was the case is that there,s no noise if the engine is not under load, when running through the gears on the stand it's o.k.

Changed clutch bearing today and still the same, only thing i can think of now is that one of the bearings although all are new is spinning in the case somewhere.

stripped it down today and still can,t see anything wrong, I,m gonna change clutch bearing anyway just to rule this out but don,t believe this is at fault, any ideas guys, last option I,ll have to split cases again, just looking hopefully for a simple fix.
