Diagnose this chit! - October 21, 2007, 07:58 PM

Bike is on a cycle of 'runs like chit'...'runs great'
Get on in the morning,idles bad...hit the throttle it dies.
Turn it off,turn it back on,runs like a champ.
Turn if off again,runs like chit.Then it runs great again.
Literally,every time the bike runs bad and I turn it off and restart it runs good.Then when it runs good and I turn it off and restart it,it runs bad.

Took me a while to notice the pattern,I thought it was a fuel problem,now I'm thinking it's an issue with the CPU.I friggin hate anything electrical on a bike,can the CPU be reset? Im sure I fugged with it when I screwed up the timing when I put in a manual CCT,but I fixed the timing.

Well you see, Norm, it’s like this…A herd of buffalo can only move as fast as the slowest buffalo. And when the herd is hunted, it is the slowest and weakest ones at the back that are killed first. This natural selection is good for the herd as a whole, because the general speed and health of the whole group keeps improving by the regular killing of the weakest members. In much the same way, the human brain can only operate as fast as the slowest brain cells. Now, as we know, excessive intake of alcohol kills brain cells. But naturally, it attacks the slowest and weakest brain cells first. In this way, regular consumption of beer eliminates the weaker brain cells, making the brain a faster and more efficient machine. And that, Norm, is why you always feel smarter after a few beers.-Cliff Claven

So the 98 is a carbureted model? If so, the carbs are dirty and need to be professionally cleaned.

A quick visual inspection will determine if you have carbs or fi

from a 11/98 review

... turned the ignition and heard the digital fuel injection start up, one of the many changes to the new GSX-R. Gone are the old 39mm carburettors, replaced by 46mm, large-bore, fuel injection throttle bodies. This new fuel injection system constantly monitors the engine, calculating the ideal air and fuel mixture by using engine rpm and air intake pressure. In the unlikely event of an injection system problem the computer will perform a self-diagnostic, which is subsequently displayed on the water temperature tachometer face.
