Posted March 7, 200718 yr If a Fazer engine is supposed to be a de-tuned Thundercat engine, how do you go about re-tuning it to get the Thundercat performance?
March 8, 200718 yr Think there's a bit more than just a fiddle here and there, It's probably got softer cams on it. To be honest there's not a huge amount of difference anyway ... both are de-tuned R6 engines.
March 8, 200718 yr Moderator Yep....gotta agree with Chris here Softer cams & possibly smaller carbs are usually the changes that Yamaha does to different models with basically the same powerplants.
March 8, 200718 yr Author Oh well, looks like I'm stuck with it as it is then. My back and neck wouldn't be able to handle the riding position offered by the Thundercat or R6, whereas I'm ok in the sit up and beg position on the Fazer. I suppose I could always go for the XJR for a bit more muscle, but that's just so much heavier to haul around.
