Good day. I have a gsxr 1100m. It keep on blowing the no 1 plug. Can the replacement of the tanktap be the problem?

It sounds like its possibly a bad regulator/rectifier. I have posted a link to a video on how to test your regulator. How to test 2 plug Regulator Rectifier for K6 K7 GSXR 750 600 1000

Send the unit to a good service center and you will save yourself a lot of frustration and headaches- let them have those.

No but this should be an easy one to trace the problem since its the one hot lead from the battery to the switch. follow it and you should be able to find where it grounded to the frame pay a close attention around the steering area where the wires come from the farme to the ignition swithc.

if its fouling out then you need to move the needle down or use a smaller jet. Stage 3 are a full rich adjustment. Maybe fo to stage 2,

I lost 40 miles to the tank when I put a stage 2 in my 1100 sabre. Regained half that when I adjusted the needle and came down one number on the jets.

my 1993 gsxr wp is running rich and only doing 25 mpg, ive changed the air filter and dropped the neddle a notch but is still rich. any ideas cheers<!-- from fixya rte -->

sounds like the audio stage riving the channel has a short circuit on it.need to go through the amp stage
