Sounds like the carbs are starving at speed.

**Anonymous** · 08-13-2002, 12:26 PM

how i can resolve that?

cleaning carb?
changing carb?
....

Dirty or unsynced carb problems are seen during all phases of operation, usually. It may be a clog in the fuel line limiting the flow of fuel to the carbs.

There are also several "jets" that control how much gas flows throught the carbs at certain throttle positions. Uhm... someone posted a picture a while back of which jets open at what throttle position.

My first guess would be a resticted fuel line.

For sure check your feed into the carbs (filter and lines). If not that, you will probably have to get the carbs cleaned really good.

if i go to a suzuki store and i ask to clean my carb, that will resolve the problem u think?

Could be the float levels are set too low. Not letting enough gas into the bowls and when you go faster, they are emptied faster. If you have any kind of mechanical ability, I would recommend you get a book, check out the carb rebuild section of this website and do it yourself. My local Suzuki shop told me it would cost $200 for the labor plus parts to have my carbs rebuilt. I did it myself, and they work just fine. It's a simple process, just takes a little time and patience.

i have the book for my bike but that seem hard

i need to only clean car or change piece in it?

**Anonymous** · 08-13-2002, 05:02 PM

The shop I went to only charged $175. That was for carb rebuild/sync, check valve train, change plugs and check fluids. $175 for parts and labor.

tomorrow i will go to my suzuki reseller to take my fuel filter...
i will ask to how that cost

Fuel filters are easy to clean. Simply reverse the flow through them for a bit. In-line filters I can run a shot of compressed air through them to get a good clean. The in-tank filter can be cleaned with soap and water (its plastic and a very fine metal screen), allowed to dry and reinstalled. If you go as far as to pull the in-tank filter, you might as well clean your tank out too.

Fuel delivery on motorcycles do not necessarily coincide with speed, but has to do with throttle position. You could use more fuel at 70 KPH if you were in 1st gear and full throttle than you would by doing 130 KPH in 5th gear at 1/4th throttle. So, if it's starvation of any form, he should be able to make it happen by just getting on it hard (full throttle). In fact, he should be using LESS fuel on the "motorway" than he would if he was getting on it around town -- during half, to full throttle, acceleration.

OS2, do you have problems making it go fast from a stop sign?

OS2 Pull the petcock from the tank and check the fine mesh filter on the tank side of the petcock.You may have very fine rust in the tank collecting on the screen and when you shut off for a few seconds the rust comes off the screen and you can run for a short ways again.Does this sound like what is happening?

**Anonymous** · 08-13-2002, 05:58 PM

dallyr, is not my fuel filter, it's my air filter. It is a lot dirty i tried to clean it with compressed air but nothing seem to remove....
