Posted January 8, 201213 yr Ive just fitted some heated grips to my 1999 FZS600, went about a mile up the road and got a missfire. Rode back home and it seems cyl 4 is not as warm as the others. I took the tps off and put the ign on and the needle went up to 3000 then zero and then 3000 and keeps doing this every couple of seconds. Any idea what this may mean?
January 8, 201213 yr Are you saying you've left the tps disconnected ? If so this is why the tacho is doing this as 3000 on the tacho is an error message for the tps.
January 9, 201213 yr Author Hi, YPVS TONE, yes its all sorted now thanks. I drained no4 float bowl out and alls well. I disconnected the tps to see if a code would show up, if maybe I'd knocked something off when fitting my heated grips. It was just a coincidence that after I'd been playing with the wiring, that I had a fuelling problem too!! Thanks anyway
