Where to buy jets for Mikuni Carb

[frostyflammable]

I have a 34mm flat slide and with my setup (420cc with stage 2 GPS kit) the engine seems to run very nice until about 3/4 to full throttle, then it seems to bog down, and the spark plug seems to suggest it’s running rich. I also see some black smoke coming out the exhaust. I moved the c clip all the way at up and that helps... rpm went from 5800 to 6500 before it starts to complain but I think my 250 main jet may be a tad big.

I looked at GoPower Sports https://www.gopowersports.com/mikuni-main-jet/ but this one does not show as compatible with a 34mm.

So basically where can I get some good jets, probably 240,230 and a few more on the smaller side to try and tune this thing.

Thanks.

I got mine off eBay. Just make sure your main jet looks he same as the one in the pics they are selling as there are multiple different sizes and shapes.

If you can’t find them on eBay try- jetsrus
Good people and you’ll know that your buying genuine mikuni- not cheap china jets that may or not be the size your looking for.... just trying to help
