guys

I used to ride my Bultaco only now and again (didn't have the GasGas then) and I think it took me almost a year to get trough 1 litre of two stroke oil. It never worried me...

with all the above. JUST DO IT!

Here's how to: Some remarks: - don't over do it with the amount of grease, the exces grease will find it's way out and maybe contaminate your brake disc. - Use special water resistant grease: MX shops and mountainbike shops normaly have some - Be VERY carefull when you pry out the seal as not to damage it. - And, as stated by Charlie, make sure the side of the bearing where you have removed and re-installed the seal, is on the inside of the hub.

Would this happen to be an All Balls bearing kit? I had such a kit for my steering head with extra seals for other brands of bikes which were useless to me...

Normally the bearings have seals built in like this one:

I had to give up because my arm got sore from the heavy GasGas clutch lever, but it was fun nevertheless

Damned, now I'm in the mood for dancing instead of trials!

It's a floating disc so yes, it's normal that there's a little play

I used to run my 315R at 80/1 (and run my GasGas the same) and when I removed the barrel it was very well oiled. Your comparison with gearbox oil makes no sense. And here's another well informed opinion: http://www.gasgas.com/Pages/Technical/measuring-pre-mix.html

I don't think there were much engine mods on the later model, but I would go for the later models, the better brakes are worth it imo

You're kidding, right?

In what other sport can you buy a bike that was ridden by a world champ!? Take good care of it :-) How much does the bike weigh with all of those steel parts?

Somebody going to this event? I am... http://www.msig-gressenich.de/

Do you close the fuel tap each time you put your bike away? If I didn't do that, my 315R used to be hard to start...

Yes I was there with my Bultaco, I'm a member of the club in Genk...

Aha! Another belgian, nice, now I'm not so lonely anymore between all the native's

Me too I was also wondering about decent ventilation
