I found the needles on both sides stuck in a round hole. I cleanse them both then reinstalled them. Then put everything back together. Now the bike runs great. It idles good. And the clutch works great.

Ryanstalin, glad you got it sorted out.  Yep, carbs are confusing but when you have tinkered with them a lot, it's second nature.

Those are some dirty float bowls.  Looks like brown sugar.  Wow!

yeah this bike has previsously been through mud, a long time ago. quick question, is it recommended to change out the oil, what kind of oil and how many quarts?

bombsquad83

Mud doesn't enter the float bowls (unless your whole bike took a dip).  It's most likely gunked up old fuel you are seeing there along with whatever particles of rust and whatnot that came through from the gas tank.  You should really clean all that junk out with some carb cleaner. You don't want it clogging up your jets or your needle valves again.

jestercinti

Simple answer:  10W-40 Motorcycle oil.  Make SURE it's designed for motorcycles.  Buy 3 quarts.  You will need a full 2 quarts and a partial third.  When checking oil from the dipstick, place on centerstand and DO NOT SCREW IT IN, just drop the dipstick in the hole, and check level that way.

Look at the Wiki for more info:  http://wiki.gstwins.com/index.php?n=Maintenance.EngineOil

PLEASE tell me that you cleaned out the brown sugar from the bottom of your float bows AND the rest of the inner workings of the carbs   :icon_eek:  It was unclear in your last post.

I did clean everything in hot water, degresser and qtips. It did have some rust dips. But other then that its good to go. I will be getting oil tomorrow. It's mobile 1 fullly syn 10w40.three quarts.  It's 9.97 a bottle. But I get a 10% discount.

jestercinti

Good   :thumb:  Keep us posted.  And change the filter too, not just the oil.

Ryanstalin

true, can I buy the filter at walmart? whats the part number?

jestercinti

Fram CH-6000.  I don't think they sell at Wal-Mart.  Have only seen it at Advance Auto Parts.

Fram or OEM.  That's what I use.

Okay Ill get it all tomorrow. btw I added some tinker lights, caution they are bright.



Ryanstalin

well Im back. it doesnt have any gas getting to the right carb, so now it has no power. did I not seat the float needle right?

bombsquad83

I have a feeling that your needle valves are sticking.  Not really surprising based on how nasty your float bowls were.  No matter how much you clean those valves they might just keep sticking.

Ryanstalin

But the left carb has plenty of good. You can even ride the bike. But its still lacking the power like it did have.

Ryanstalin

I cleaned them again and its running like it should right now, worried that the needle will get stuck again

They will.  You will need to order OEM needle seats.  DO NOT buy aftermarket.  They say that they fit, but don't.

Also, make sure that you clean inside the hole where the needles go.  Otherwise it will stick again for sure.  You can keep cleaning them, or buy new.  Go to bikebandit.com, or go to your local dealer.  They are expensive, but think of the well running bike you will have when it is all done.

Depending on where you live, you may be down for the Winter.  Good time to work on the bike.

i live in the south, it doesnt get cold til around feb. and I cleaned them again, but they are stuck again. I cleaned everything this last time. it seems like it has good power to the left cylinder tho. think I could get away with ordering one set? and maybe from ebay, if theres any oem on there.

jestercinti

eBay is also good.  Look for Pinwall cycles.  They are in Ohio, but they buy wrecks and parts bikes and part them out.  Quality stuff, and they are from Ohio (like me) so it can't be all that bad.  Pinwall also tells you the make and model bike it's off of and the mileage.

I'd try new or gently used OEM ones.

K&L = aftermarket = probably no good.  OEM means Suzuki parts.
