Ok Kiddies, Uncle Thump had an idea. probably a bad one, but it might help out with some of the carby questions that will always plague minis...
My idea is thus.
Using the template below, and the "ADVANCED REPLY" option, fill out all the details ON YOUR SPECIFIC BIKE, and please list your BIKE MODEL, and CARBY TYPE in the heading, so that searches will bring this thread up easily.
List engine size, carby type, carby diameter, Jetting specs, and type of jets used, eg Keihin or Mikuni style, engine specs ie: standard or modified, and if it's modified, WHAT modifications have you done, and the area in which you live.
(we want exact I/D's on carbies, not "it's a qenuine fake mikuni 30mm")
The idea is that others with carby issues, or looking to upgrade carbies, can look through here, find a similar set-up to what you have THAT IS RUNNING PROPERLY, and can use your settings as a base guide to set up their bike. The idea of having where you live, will allow some idea for different altitudes as well. (cheers Dready, good idea mate!)
REMEMBER WHAT WORKS FOR ONE BIKE, MAY NOT WORK FOR ANOTHER, HENCE THE REASON FOR ACCURATE DETAILS.
This thread will only have specs of riders bikes. any questions you have, for members with setups similar to yours, PM them if you have queries, or post in techmasters. Any non-relevant or off topic posts will be deleted, we want to keep this thread as relevant and on-topic as possible.
Thanks guys, and please, those of you with accurate details, and well-jetted bikes, please add to this thread!!

china boy sounds like you need to richen out your jets, basically if needle clip is all the way you need to go bigger, needle should sit in the middle 3 grooves

yeah china i think you'll find a 12.5 way too lean on the pilot... 20 would be closer i reckon....

Hmm... seems like we can see a bit of a pattern forming on jetting, especially with the OKO 26mm's...
seems everyone is running 36 or 37 pilots, and 96-100 mains...
