GZ250 Sluggish, hesitates, slower than normal????

[Todubs]

Pulled the carb and tore it apart, per the shop manual. BTW, inside of carb was clean and shiny. Put carb back on and no change. Still bogging down under load. It starts and revs fine, but when riding, it has the hesitation and is sluggish (same as reported in the start of this thread).

Oil was changed before storing for winter, I usually change it agian before the warmer weather and riding again.

Wife wants to take it to dealer to let them figure it all out, but I would rather save money........

Just a thought, how long has it been since the valves have been adjusted?

if you cant hear the valves tick they might need adjustment, i asked my local mechanic about checking the valve clearance on my bike, he says can you hear them, i said yes, he said do they make a strong ticking sound, i said yes he said more than likley they are fine, when they start to quiet down is when you want to get it checked out.

Have you actually tried carb cleaner in the gas ?? You didn't mention that.
Some of the tiny little passages are hard to get to and easy to overlook.
It would be worth a shot before you take it in.

Put the recommended amount for a full tank in only HALF a tank of gas; run it for a while and sit overnight; if there is any sign of improvement, then fill the tank and pray.

Have we asked about mods.....like pipes or air filter ??
Have you checked the air filter ??

"Oil was changed before storing for winter, I usually change it agian before the warmer weather and riding again."

Tell me why you do that? What are you trying to gain by changing out the clean oil again?


You also could squirt some carb cleaner right into the carb and let it sit for a while before running it, to see if it can clean some junk out.

Condensation in the crankcase can separate from the oil and gum up the cylinder after it sits for a while.

I personally think it's being a little anal-retentive though.

I change my oil before putting bike away for winter.I don't change oil in the spring until 5000 kms.

OCD. :poke2:

There really is NO good reason for doing that for an annual storage of a few months. NONE.

I think it probably got started by someone seeing that as a recommendation for LONG periods of storage......like YEARS....and ASSumed that it would somehow be beneficial for short periods too.

It is not true. Total waste.

That's what I was getting at, but the written word doesn't convey a sarcastic tone (which is probably a good thing).
To me, that's a waste of time and money and resources and environmentally very unfriendly and accomplishes nothing.

The owners manual does say to fill the crankcase COMPLETELY with fresh oil for storage, then drain it and add fresh oil to the proper level before riding. I didn't see a length of time considered storage, but I would say 'over the winter' seems like a long time for it to not be run. To me 4-5 months is pretty long-term for an engine not to be run..
