no air/fuel adjustment?
Having carb issues with my 2016 Pitster Classic 125 Pro (Skyteam ST125-6B) it is running lean and I'm not finding any way to adjust it. The pilot needle valve has no adjustment grooves like the older carbs. There are only two screws on the carb. A throttle stop and a float bowl drain. WTF? Do I have to swap pilot jets just to change the mixture? HELP!

Perhaps this would work for you: http://www.ebay.com/itm/24MM-MIKUNI-...wasUDw&vxp=mtr
There are measurements in the description section that you can compare with.

I just got a SUPER FAST reply from Gary at Pitster Pro. He stated these new carbs are tamper proof as per EPA/California Emission Regulations. I knew when I saw that spaghetti-fest of emissions this might be a nightmare. That explains why there are no adjustments to air/fuel mixture. Not sure what I will do now. I guess I have a $2000 CT70 clone to park in the garage and just look at. I'm thinking the Honda dealer was right. I should have kicked in a couple more thousand and got a bike I could ride from the showroom with no labor involved.

Thanks for replies. Waiting to see if Gary has any ideas. I'm assuming I'll be replacing this tamper-proof carb, or playing musical chairs until I find a pilot jet that will work. I'm about two minutes from rolling it to the street and selling it for best offer.

If you will read a few of other carb problem fix's you will have a nice running bike. the sealed bit is just a brass plug that you drill then put a screw into and pull out. If the float bowl has security screws they can be removed too. New carbs are not expensive either if you can't run a drill/
