pastyman:
sorry but i have another couple of problems that i hope you can help me with please

1. when i squeeze the front brake the lever is extremely soft, so i thought no probs it just needs bleeding - now here's the problem, as i was bleeding the system i noticed that the wheel was moving does this meen that the wheel bearings are shot

and number 2 is I eventually got the bike running and when i put my hand on the exhaust downpipes i noticed that only 2 of the pipes are getting hot. Now initially i thought that it was one of the coils but then realised that it couldn't be as it was 2 pipes that were adjacent to each other

Now i have replaced the spark plugs, HT leads, and checked the carbs and dont know what else to do

Please help

cheers
pasty

Seamus:
With the front brake, is the caliper set correctly? It is a floating unit that operates from one side with a pivot to apply the second side. Possibly a seized pivot, Do both sides move when you apply the brake?
As for the engine, which two pots are not working? The carbs are fed in pairs via two petrol pipes. Are these flowing fuel to all the carbs?.
A good place to start

pastyman:
with the brake only one side moves
with the pots - as im sitting on the bike its the 2 that are on the left

K2-K6:
With the brake caliper, If you undo the two bolts holding the caliper together and move the parts out of the way then you should be able to move the arm easily with your fingers on it's locating pivot that's still bolted to the fork. If this is not possible you'll have to free this for the brake to work properley.

If it's siezed too close to the wheel it'll have the effect you've felt in that it pushes the piston too far back into the caliper when released so that too much lever stroke is used to move it into a braking position. It'll also bind when running unused probably.

pastyman:
a1 advice thank you - it was exactly what you had described

with the other fault it appears that somebody broke into my garage and undid the 2 jubilee clips that hold the carbs to the engine  :-[ ;D :-[
