I did it! I cut my muffler off and added a new one.

The #130 jet hole was smaller then the #120 i took out of the bike. Why ?

They either gave you the wrong jets or you're eyeballs are mistaken.

I would just go back.... or go to a different shop... and get main jets that look just like yours.
At this point, just use e-bay. Buy a handful and then help out others by giving your extras to people on the board who need them.

I would send you what I have in my drawer, but I don't have anything bigger than a 122.5, which I don't think will do you any good.

I took out the jet holder too just to make sure my eyes arent buggin. Lol

Jonathan, thank you very much for good explanation. I learned a lot here

Ok, i went to suzuki dealer and they said thats the only jets they have with that part # even tho the manual has different #. I need an after market jet or jet kit or carb kit worth $80+ . I aint doing that. I asked him to ask the mechanics there to see if they have one, they do not have one..so i asked the mechanics to check
what size threads the original was and they said there are hundreds. I said get a thread gauge. They didnt want to. I walked out disgusted.

Have you tried any small engine repair shops. Also try different brand moto shops for the part if you have the correct part number.

Thanks alot guys for all your help. I went to a motorcycle repair shop and they had a #128 main jet that they opened to a #130 ( so they say) i didnt see them drill it bigger so i have to take their word for it. I put it in the bike and notice NO differnce yet. Didnt get into 4th or 5th gear or go on the highway. But i do notice the motor is extremely hot, hotter then ive ever noticed. And has a smell of very hot oil.

So you've been at this for over a month now. I have a solution to your problem. Do you still have the original GZ muffler you cut off? If not, get a stock one and put it back on, put in the stock jets, the bike will run fine and you'll be happier in the long run. And the bike will be better off too. :poke2: :poke2: :neener:
