I got my carb parts from a local Suzuki dealer. You can also get parts for this machine from www.worldofpowersports.com or www.bikebandit.com. You'll probably have to get varying jet sizes from the local dealer, though.

Hint: If you've removed the intake and exhaust port restrictors, the main jet should be a #75. I bought and experimented with a whole range of sizes and that one gave the best performance. I also drilled a few extra holes in the airbox lid to improve intake airflow, since its original hole is smaller than the carb throat. Engine noise through the carb goes up but so does the torque.

What do you think needs replacing that is adding up to $70? A couple of jets and gaskets shouldn't add up that fast.

 

Thats my thinking too. I printed up a breakdown and the parts list that went with it. of my carb. I circled the jets and all gaskets and rubber (anything that could have deteriated) I also marked the float. That was about it, while I was still looking at the breakdown my friend took the parts list and started adding it up. He came up with a total of around $70. This was from a internet parts house (down recall which one) and the shipping was $18. Thats BS! I later compared the prices with my local shop and they were about $1 + higher per item. But, without the rediculos shipping it would be cheaper to get parts locally.

I have done the same mods you just refered too. But, I am running a 65 main. Never tried a 75 but I did have a 74. I couldnt get it to run good with the 74. It kept wanting to bog down. Tried the 65 and man it was alot better, so thats what we stuck with.

 

Take off the exhaust pipe restrictor, too. It's a little cap with a small hole in it on the very end of the exhaust system. That opens the exhaust quite a bit, improving airflow and offseting the additional fuel from a #75 jet. At least that's how it worked for me.

I wouldn't think you needed to replace the float unless it has a hole in it. It's not rubber, it's plastic and should last indefinitely.

 

I just added it up myself, and evidently my friend does not know how to use a calculator. My total was $50. I could probably shave some off of that. You have to buy the whole top assy. just to get one gasket, and its $11.82.

 

Idea: Before you spend the money, try to actually confirm what is really wrong. No fuel getting into the cylinder ought to be a "findable" problem in some way. I know that sounds trite, but I'd want to make sure I was spending the CORRECT money beforehand.
