Greetings,

I've noticed lately that my 02 ST with 15,000 miles is starting a little harder (turns over 7-8 times before igniting as opposed to 3-4 times). Also, After decelerating from cruizing and adding just a little bit of power the throttle control seems a bit eratic in that it has a tendency to jerk forward.

This problem leads me to believe that the idle/fuel mixture is out of wack; I've checked the air filter and it looks clean.

Could a TuneEdit diagnose and resolve this kind of problem?

Have any of you encountered a similar situation, and if so, what was your solution?

Thank you in advance

Did you have your valves done at 12K miles? What about having the throttle bodies sync'ed?

I did have the 15,000 mile service completed; however, I'm beginning to question their thoroughness. They did say they checked the valves and no adjustments were needed, and I do not hear any excessive tapping.

I can only assume the throttle bodies were sync'ed.

Guess I'll need to take it to my new dealer here in PA.?

Mine seem a little tough on the start. It has the original battery. 15k on mine.

Maybe it's about time I put a new one in? :???:

The battery seems fine. I noticed right after replacing plugs from winterizing it started right up rearing to go. But now it struggles to start and when it does catch, it seems to be a strain to start.

I'd run a batter test. Cheep and easy to do.

Maybe I need to expound on the term, "struggles to start".

The starter turns over great and doesn't even begin to slow; however, it takes approx. 10 secs for the fire to light the gas as though it has a week spark or...?

Could a low battery allow for a proper starter 'RPM' but not give the needed juice to the coils?

Nevertheless, Battery Test...Will do...Thanks for the suggestion.

This may sound simple. However, maybe you got a batch of bad gas?

Otherwise, it almost sounds as if your plugs may be fouled a little. I've never had it happen to me, but it appears that one of the plugs in the Sprints will often foul. Especially if it's kept outside.

FWIW

was this right after winter storage?

I second the try fresh gas suggestion. drain and replace.
never encountered with my current , but in my dirtbike days it happened.

Bad gas is a possibility; especially since it started a little better this morning (took approx. 5 sec. of cranking to start).

I did not winterize, but I replaced plugs with new in March. I have put on 500+ miles since then. It had ran and started great that whole time until about a week ago.

I've never encountered bad gas, but am beginning to believe this is the case. I only run the good stuff, but am not familiar with what gas companies here in PA are rated better than another in quality. Any RAT members here know?
