anton Posted March 27, 2008 Report Share Posted March 27, 2008 Just bought a 1989 gas gas 250, it needs a bit of tlc but not sure where to get them, I need fork seals and the front brake caliper is seized so may need a new one ( brembo), also general items such as air filter,brake pads and also is there a parts of service manual out there for this type of bike. Any help would be great, tried main gas gas dealer but dont seem interested.Anton Quote Link to comment Share on other sites More sharing options...

The overseas freight might be tough to swallow, and as in any old NOS parts, you'll be paying for inflation and "storage" from the year of manufacture. GasGas is good about retrofitting updates so you might be able to use parts from a newer model that is more commonly available. Sometimes, contacting Trials clubs can be a good source as someone may have a parts bike for sale. Trials riders don't throw away anything....

peterb Posted March 28, 2008 Report Share Posted March 28, 2008 Hi Anton, I also have a 1989 250 GG aire in my collection, not a bad bike for the year. Forks are Marzocchi, seals are 35x47x7, same as a 70's Bultaco Sherpa. You should be able to free up the front caliper using the brake lever, squeezing out the pistons. I have a Brembo seal kit here but probably would like to keep a hold of it. There is no service manual for this bike, feel free to use the forum for any particular questions, or you can always PM me (personal message) and use my email address for help. Brake pads are the same as used on the 95 330's, should be easy to get hold of. Linkage bearings similar to later mid 90's bikes. Clutch plates differ slightly to the 330's, but you can easily fit these with a little filing of the tangs. The 89 internals are well made, quite sturdy, massive kickstart gears. I replaced my cylinder thinking the nickasil had gone porous (looked like surface pin holes all over) but the new one was identical! Pistons are still available but take an age to deliver, you can use piston rings from an earlier 250 Sherpa - can't remember now if one was a dykes and one plain, best to check first. Crank seals are same as 330, readily available hi temp viton. If you are really stuck, I have a new air filter here and maybe a transport method to the UK - one of our riders is off to the SSDT in 3 weeks. Footrests are terrible, best to weld on a set of Hebo pegs but mount these as low as possible and as far back as possible. Bye, PeterB.
