I have this friend of mine who owns a 98 Speed Triple 509 with injectors. I understand this was the the only year they did this (sorry if misinformed). Ever since he bought the bike it has run rich and badly. He has had it in the dealer a number of times, the have attempted to corredt the problem by remapping. This has just made things worse.
The bike has no airleaks, correct valave timing and adjustment, good plugs and a clean air cleaner.
I have put forward the theory (and I do this as a carb man not an injection expert by any means) that there is a faulty sensor somewhere on the bike telling the brain that the bike is running rich. The dealer has mearly tried to compensate for this by fiddling with the mixture via the mapping process. If he couyld find out what sensor it was a change it all should be well again, with the exception of maybe having a final tune up.
Has anyone else heard of this, any pointers.
The summary of the problemn is - running rich, dosen't do it all the time but does do it often, sometimes runs better when hot.
All help very gratefully recieved, and you may save hime from pulling the rest of his hair out .... :-D
Cheers
Nic
