On my 1980 Camaro with v-6 burning oil on one cylinder I replaced the standard plugs with single platinum at the time. Went from changing plugs every 6000 miles and the oil burner every 2000 miles to about 25000 miles and the oil burning cylinder every 6000. The plug would be totally caked before any idle degradation or miss. Made it into a street/strip ...

As they are 'pencil coils' on your vehicle, you can transfer the supect coil on to a differant plug. If the coil now works correctly whilst the one it was swopped with starts to 'misfire' on number three plug then you know you are dealing with a fault with No.3 cylinder. Secondly try replacing No3 spark plug with one you have removed and know to be working ...

Like Paulster2 above, I'd like to see what happens when that area of the motor is cleaned thoroughly so we can start looking at this thing fresh.

Remove the plug, check if it has oil on the electrode, or if it's clean. Check the hole for oil on the threads. Perform a compression and ...

When your engine was in its design and testing phase, OEM manufacturers of the various components will have tested and tested again all of the component parts to an exacting standard. You will not gain any advantage by detracting off of this standard. The Brisk plugs may offer some enhancements in a race tuned engine, but the suggestion that a plug without a ...

Peter's on it, all the way across the board. If all those checks test out, then check for a sticky valve on that one cylinder. In fact, adjust valve lash on all cylinders. Then check compression.

Your description is making me question your diagnosis so far, in terms of is it one cylinder affected or all. Because a GSXR should be able to run (badly) on 3 cylinders, and cleaning the fuel cap shouldn't make a difference to just one cylinder. From your description i'd start by replacing the fuel and ensuring it flows freely to the carburettors. (is it ...
