Spoke to gas gas today, they say it sounds like it is running rich and to try a smaller jet. Failing that to try another cdi unit and carb from another bike to try and isolate the problem, any offers? Will post if I get a result

I have an 04 280 pro that has the following problems: Sometimes difficult to start, if i am lucky on 2nd kick Just off idle speed engine runs erratically (especially when on slow sections), but fine when throttle opens fully. These problems have been like it since new but i am now getting annoyed by them. Carb has been cleaned and all jets checked and blown through with air line. Gone through various settings on tickover/air screw/needle but none appear to change things. New plug fitted. Air filter cleaned etc. Any one else had similiar problems and how did you solve them. Thank you

I have just had the same problem with mine It was the seals in the slave cylinder that had worn slightly allowing air in but not to leak fluid so like you was having trouble diagnosing the problem. (see water pump thread for related advice ) I have been told that using synthetic oil in the gearbox causes problems with the seals, not sure about this but there will be someone on this forum that does

I honestly can't believe the council are in there right minds I can completely agree with the council wanting to get the excessive noise issue resolved but closing it only effects the majority of people who dont have noisey bikes. What sort of people can do this to trials riders, do we have to start resorting to terrorism to start getting the support we need from these people. When you look at all the support they give to groups they consider to be a threat to society and then look at the way they treat generally law abiding hard working people it makes you wonder if it is all worth it . As for ideas get a petition together with as many user groups as possible that benefit from this venue. Get in touch with your MP and the police try to get them on your side, after all they dont want bikes riding illegally do they Try to come to an agreement with the council to allow continued usage and you in your turn will stop all noisey bikes using the land, if thats the problem? More often than not its used as a global excuse for ridding society of the evil breed of people in this world that just happen to like bikes (Its about time all the manufacturers worked together to stop this at source rather than leaving it up to a few thoughtless/selfish induviduals ) I'm starting to rant

What do you mean the right 2 slots! Is there more Will try again tomorrow when my patience level gets back to normal

Hello all I have a 2004 gas gas 280 pro and have taken the water pump off so that i can replace the seals in the clutch. Can someone tell me the best way of alligning the pin in the pump shaft with the slot on the drive gear, i can no longer stand the stress of trying to locate it I have also noticed that when you wiggle the shaft water drips out. Is this normal? I have probably got water in engine now thinking about it I have got to renew the bottom gasket on the barrel any advice on things to be careful about? Thank You

Have i stumbled on to the blue peter site by mistake How much will they sell on eblag for

I have been doing quite a few miles on my 04 280 pro on trails and tarmac. Are there any problems i should watch out for apart from the normal routine maintenance? Does it have any detrimental effect on the piston rings as i am not sure how often these need to be replaced.

i have and still have the same problem with my 04 280 At one point the pickup was actually rubbing the flywheel and it stil wasn't happy starting. I have since been told that it may be the idle jet (need a slightly larger one) but i haven't got round to changing it yet Failing that it may be the cdi, spark plug or the lack of effort when using the kick start

i had a similar problem on my 04 280 It was cured by spening a long time tapping the hydraulic line from the engine up to the master cylinder whilst slowly pumping the lever until all the bubbles stopped.

i would have thought that all risk assesments are the same for all trial events they just need to be modified to suit any different venues (site specific). I think damage limitation is the big thing nowadays, whenever you go to a motorsport event it will always say it is dangerous you spectate/participate at your own risk. Surely the ACU have someone to do the risk assesment for you, dont they?

probably deliberately so just in case things did go wrong. they can then say you misinterpreted what was written, so the blame falls onto someone else. Or am i just being cynical Always cover your a***.

Always keep your bike clean in the right places, not just because she will look pretty. I would rather spend 10 minutes on the chain and sprockets than wiping the mud of the plastics. A clean bike is always worth that little bit extra and you get more respect from the majority of the other riders. I hope your mates arent as slack about there own cleanliness

I would assume its because when the casing is hot the expansion causes the bit that was rubbing to move away from the flywheel. (the "bit" is a technical term ) Glad its sorted i thought it was aomething serious.

sorted noise
