removing the carbs and the carb I took the carbs apart and them.  The pilots dirty, the other jet systems pretty clean.  I had a replacement o-ring kit but didn’t put it to use when I the carbs would have to be from the rack and completely

 That’s a lot of work!

After I cleaned the bodies of carbs 1 and 4 carbs you can see when they’re on the bike), along with the tops.  Then I painted on a coat, using a paint  The clear coat is “Diamond Finish” made by KBS

 This is a great product, it the metal look shiny, is to brush on and it’s fuel  The carbs look nicer.

By the way, the carb boots wasted.  No way they could be And Suzuki carb boots O-rings that fit between and the head.

 Make sure and your O-rings or you’re for hard times riding bike.  Air will through that space, a lean condition and crummy response.

I was prepared and had bought a set of carb boots in good off E-bay.  I also bought new O-rings from Suzuki. try using regular O-rings the hardware store as replacements.

O-rings for these carb must fit right and they are of Viton, a fuel resistant  O-rings from the plumbing at the hardware store aren’t resistant.

Putting the carbs on was another chore.  These are the carbs I can remember putting on I had a Honda CB400F 30-something ago.  The squeeze the carbs into the boots is and then you’ve got the airbox there in the way too.  Make you get the throttle cable on before the are all the way back into the boots or

 I didn’t connect the cable had to pull the carbs halfway out to get the back on.  It’s not easy.

on, airbox on, time to ride.  I it out a few times around the neighborhood. jetting was very lean.

some research, I saw that these models came the motorcycle manufacturers were to meet new emissions guidelines.


Drill out the cap over the screw and adjust it to make a mixture at idle.  The screw and its cover is just from the big cap that fits on the top of the  The cap has a little hole in it stick a small drill bit in carefully drill through it and push too far down or you’ll the pilot screw.

 Then, take a wood stick it in the hole and pry the cap out.  Or at that’s what I read.  I pry the caps out so I took a larger bit and opened the holes enough so I could turn the screws. turn the screw clockwise it bottoms, then back it out 2 to start.

 There are four so you have four holes to and four screws to adjust.

With a richer off idle I rode around the neighborhood more and noticed surging at throttle.  Reason — needles that control the power.   Researching a bit more, I the top from each carb, the slide out with the rubber (careful not to damage the diaphragm, are very expensive to replace) took a snap ring removed the snap ring the slide and pulled the needle

 The needle has a plastic on the top of the e-clip and a washer underneath.  I some washers at the hardware (#6 size).  I placed two washers on top of the and one on the bottom (plastic doughnut not anymore).

 One problem the washers was the outside diameters too big to fit in the slide hole.  Luckily I had brass washers, which easy to file down the edges.  #4 washers have the outside diameter, but the inside of the ones I found at the store not go around the needle.

Taking another spin the neighborhood, now the bike idles and runs into the midrange well.  Still hesitating at throttle!  I don’t know the Suzuki is using the stock stock airbox and stock jets.

 Maybe we’ll to go up on the main jet sizes, unless else is causing this

more confident, I rode the further around.  I drove my house down to Kapahulu. not far just a few miles.  I stopped the met someone and then jumped on.  Pressing the starter button, it barely turn over.

Riding a few miles with the on almost … the battery is new, by the way).

Stator and problems are common with GS models.  I had suspected the bike need a new stator a year ago I bought it.  And I had a new stator away, I had gotten it for a good on E-bay.

We’ll talk that in the next post.
