If you ever have any tuning work done check it out before you pay. We have just been ripped off by a so called race prep specialist,Fatman on a Yamaha???. Invoiced for a tuned engine only to find out it is still the same as it left the factory. The same person also invoiced us for fork work done by WPS and was paid but they have informed us that they have had no dealings with him and the forks are stick stock. The moto is check it out.
You always get one bad apple in every barrel

Was the engine never dismantled or anything, or was it just ineffective tuning?

It was never touched, and the forks that were supposed to of been done by WPS and paid for are still standard
