Hi guys,
For some reason I do not have any luck finding a set of main jets for my stock 2003 Yamaha Zuma carburetor.
The carburetor is a Tk 14mm carb. If I am right the main jet has 6mm threads.
I am looking for jets from 80 and up so I can get it tuned well for a new pipe.
Could anyone help me with finding a jet kit online?
I am located in Europe so it would also help if the webshop was in Europe to keep shipping fees minimal.
P.S. I am sorry if this is the wrong section of the forum for a question like this.
Thanks

mikuni 11/22 jets will fit or dellorto 6 mm fit
Just buy a large range because a yamaha 80 does not flow like a mikuni 80.
I found for genuine mikuni I needed about 5% larger 85 to get better cylinder temps as the 80 .
If you are running stock air box with a pipe and kit low 80s to mid 90s will get you in the right place .
If you are going open filter get some get some that you another 10 points

I have a large set of 6mm dellorto jets that I have from other projects but if I remember correctly I have tried using 6mm Dellorto jets in the stock Zuma TK carb and I had no success.
Are you shure that 6mm dellorto jets work?
I will give it one more try then.
I have an Athena 70cc kit and the reason I am looking for jets is because I have aquired a Gianelli Extra V2 pipe and would like to try it out to see what can be gained with that pipe. And yes, I am running the stock airbox.

I bought this set from Amazon Glixal Jog 50cc 72cc 1PE40QMB... www.amazon.com/dp/B06XHY4Y9H?ref=ppx_pop_mob_ap_shareHope the link works. I’ll see when I post reply. It goes by 5’s up through the range. For fine tuning you need smaller steps but for most things I think going by 5’s isn’t horrible. These jets fit my stock Chinallorto |

Thank you guys for the links and advice. I will try once more with the Dellorto 6mm jets that I already have. I must have done something wrong the last time I tried the dellorto jets.
If they do not work I will have to source one of the jet sets linked above.
