Re: Airheart Brake Bleeding

All seals for a rebuild of Airheart systems are available on line or at a 'seal' distributor. You will also be surprised how inexpensive they are. Just purchased some myself and I got them in Buna rubber and they work great. I was in question about how the seals would react to my fluid of choice so ...

Re: Airheart Brake Bleeding

If you are attempting to push the caliper piston deeper down into the caliper make sure you remove the master cylinder fill cap first. Watch for overflow at the master cylinder with the cap off as you push the piston down in the caliper. Better get some rags or paper towels handy, just in case. R.E....

Re: mc 92 parts

Any bearing distributor will be able to hook you up with crankshaft bearings.

Mc carb kits, thats a different story. Terry would be a good place to check, if he don't have ebay might. Tilloston carb is a good alternative because they perform very well and parts are easily available.

Re: Airheart Brake Bleeding

Alan Upon further review of your brake system it is advised to replace the copper brake line with the plastic brake tubing. Reason being is that karts 'flex'.
