250-500cc Rear Brake problem 2001 CR250 Husky

VP makes the 30 year fuel for classic and collectable cars. I think it's just above 100 octane... A VP dealer was telling me about it. If you're going to use pump fuel just make sure you use it up in 90 days and that it has no ethanol and you'll be fine for most bikes so long as it is 93 octane or better. One thing that is beneficial besides the shelf life is that if you tune your engine to a race fuel like VP110 you will get more out of it especially if you mod the head for more compression and advance the timing a bit.

I use race fuel in every motorcycle, chainsaw, weed-eater, leaf blower that I own. I probably spend an extra $300 per year on the fuel but I'm never working on it because of a corroded up pilot jet or a leaking priming bulb or spongy "O" ring, when I could be riding. I often fix my neighbors yard equipment for a little extra cash and 90% of the time it's fuel related.... I use the extra bucks to by race fuel for my stuff.

It has been said plenty already but that thing is in amazingly good condition! I would consider to lubing it up and storing it for at least another decade! On the other hand, it would be great to ride now.

Brake fluid that old could have air/rust/dirt/water etc in it even from sitting. All of them would help the brake to not work. If you can try and back bleed, the little hand pumps are great for this if you can borrow one, even better if it has a reservior so you can see the carp that comes out of it.

Bike is running FLAWLESS now...What a great machine!
