+100 I'm with JimmyD. I'd also suspect oil as the culprit if it indeed has factory jets installed. What mechanic suggested "adjusting" the jets? Unless thats his term for changing the jets I'm lost. Most bikes are set to run lean from the factory to comply with EPA emissions requirements and installing the aftermarket pipe normally makes it just a shade leaner. I don't see how the bike is running too rich with this unless you have severely restricted air flow on the intake.
question about jetting
Hi everyone! Well I am back with another issue with the 89 zx-10. Got it running with help from the dealer. Here's the deal, after pulling the plugs and checking they are very carboned up. The mechanic says that the jetting was not replaced, but he recommended maybe readjusting the jets to run leaner. Now, I have a full Muzzy header system on the bike. Would it be best to go with a jet kit or try and adjust stock jets? I have been reading about something called the "Flow Commander" and it sounds like it might be something worth trying. Anyhow I am at wits end with the beast as this last time I rode it I got at least 300-400 miles before the plugs fouled out and it would only run on 2-3 cyclinders. Can anyone offer any advice? Would be greatly appreciated. Thanks!
