Hi Guys
First post here and a problem for you to solve.
My 99 'busa that I aquired recently has a very annoying trait. When the bike is in gear at low RPM the engine is very hesitant to rev, then all of a sudden the revs will build. It almost feels like a non fi bike when you replace the stock exaust and filter, and drill the airbox but don't re-jet. I know what big jap 4s feel like at low revs (had a GSXR1100WR before) and it is not supposed to feel this way surely?
If I try to blip the throttle while on the clutch all I get is a brief burp then the revs seem to die. This doesn't happen when the bike is in neutral by the way.
This is becoming very annoying and possibly dangerous as when pulling away at less than 2500RPM I get absolutely no power then all of a sudden it all kicks in. Also happens if I let the revs drop below 2500RPM while not pulling the clutch (very low speed corners). I roll on the throttle and the bike hesitates before the power comes in. The natural reaction to the power drop is to wind on more throttle which makes the eventual power spike even worse. The only solution I have discovered so far is to never let the revs drop below 2500RPM but as you can imagine with a bike a powerful and as tall geared as the busa is somewhat difficult round town.
My bike is bog stock with 6000 miles on the clock. It was serviced the day I bought it by a main Suzuki dealer.
Any ideas? Is this the fault of the ignition retard that I hear so much about and so would fitting a TRE (or doing the resistor mod) cure it? Is it something else wrong?
AFAIK no mods were done to the bike and susequently removed before I bought it.
