Suzuki 2007 idling problem.

The very bad attetude mechanic working in a shack discovered after 3 weeks that the air filter was dirty, 2 months later that the throttle sensor was faulty R4000 paid and 4 months later they took the bike to race preperations where fuel pump was replaced and the bike is as good as new. What a shame on Suzuki to not employ the right people or get them training and the client must pay for it.
