·hi everyone,
First let me tell you this looks like a great site. Very well done indeed!
I just bought a 2001 SV650S with 3k miles on it for my wife. Bike is fully stock. The bike was used very little, and sat for about 4 months before I bought it. The dust that was on it confirms this. It was running rough, but I thought that a simple tuneup and some carb cleaner should take care of the problem.
I have already done the following:
- oil/filter change
- Coolant flush
- Changed spark plugs (what a pain to simply get to the front one.) BTW, neither needed changing, but changed them anyway.
- emptied gas tank, let the bike run with tank off until it used all gas in carbs, and put in fresh gas with carb cleaner in it. Sprayed the carb assembly with carb/choke cleaner, and sprayed some down its throat while running.
- Air filter looked good, so I didn't change it.
After going through a gallon of fresh gas mixed with Gumout carb cleaner, it seems like it is running much better. Full throttle sees a little hesitation, but not too bad at all. Only steady cruise at around 4-6k rpm sees constant (but little) hesitation. There is also a lag, a delay if you will, between when the throttle is opened/closed, and the time the engine responds.
I personally think that carbs needs to be pulled out and cleaned out, and may be a rejetting while at it. I have never done any carb work, but don't mind doing it myself to learn as well. (I do all maintenane myself, including valve adjustments, etc.)
Before doing this, however, I thought I might as well get some info from this board, see if anyone has any other suggestions.
I appreciate the help.
