My mates '05 gasser keeps leaking coolant out of overflow pipe, and he has to top up regularly. Fan is running ok on radiator and does not seem to be overheating. any ideas anyone, he is filling it till no more can be put in , is this correct. thanks in advance anyone.

Wow 63 views, and nobody can help out, I will have to trawl net.

My riding buddy has an oil leak from seal behind the front sprocket, on his 2005 gas gas 280, obviously he wants to change it. Is there an easy way to get the seal out without doing any damage to engine casing? cheers in advance.

Alright Davet, I had this problem with mine, tried filing clutch basket to stop plates sticking in grooves and changing fluid and bleeding, all to varying degrees of success. In the end, upon close inspection of the discs I found that the fibre on some of them was breaking down and peeling off, so the only solution was a new clutch pack which has solved the problem fully now. So I think you may be experiencing similar problems, hope you get sorted as it is annoying and makes you tired holding bike back all the time.

Cheers, will do that Spike.

Just been given a second hand Hebo helmet, but needs two of the peak screws replacing (broken off) does anyone know where i can get screws from. Had a quick net search but no joy-cheers anyone.

Just replaced them on my mates Gas Gas, cost for bearings and gaskets was over

Cheers Curt, looks like nothing to worry about, thanks for your info.

This was replaced about a year ago and still looks as new.

Never tried to engage any gears, was only checked in neutral. Pulling clutch basket up and down seemed to produce same knocking heard when all was assembled and running.

Update on Knocking Pro, we had a good listen to bike and knocking noise seems to be coming from clutch area, also noise changes when the clutch is pulled in-but knocking noise still slightly evident. When we tipped bike on its side and took off side casing we noticed that we could lift basket of cluch up and down (may be 0.3mm movement) even though centre screw was tight. Should this movement be there and if not how can it be repaired.

We fitted new mains bearings in my mates Gas Gas pro 250 as he said it was knocking, he has just finished rebuilding it and started it for the first time-but he says it is still knocking! I have not been to see it yet but what else could it be? Little end bearings were ok, we checked for any up and down play there. Could it be piston/rings? Help please we just want to get out on bikes again.

Which is the right way round for teflon seal?

We are going to refit main bearings in friends bike tomorrow, I seem to remember something about bearing on flywheel side having to line up with an oil feed hole. Which hole does it line up with and how do we make sure they line up when bearing is tapped in?-cheers.
