update..i got the brakes working again it seems the shim i put in was causing it as i had no play in the discs..anyway i broke her in a bit today. im still not happy with the brakes tho..they are on slightly so when im a neutral its braking automatically, the brakes only come off when i open the throttle up..the thing is though i cannot get good brakes without the brake arm already applying pressure to the disc as i just dont have enough pressure from when i pull up on the brakes ive tried everything..1 other problem i had is when i did brake the engine would sometimes cut out if i didnt keep the revs up but i think that is an idle adjustment i might need.
