We all know how hard the jet kits are to find for these...one just the slow jets work the mains look way different and dont fit. I think an ez way to look for replacement jets is by the diameter of the jet thread? From my measurements the main jet bore diameter is 6mm? Dunno thread pattern and the idle jet is 5mm? I can find keihin jets tht claim for other bikes but are the right diameter but have different bolt head sizes from 7mm to 8mm to hex heads, if this makes a difference? Ive read the shorties are the same or interchangeable with the longer stock idle looking jet (sorry idk the name) , is this true? If so if it fits is the diameter of the jet all that matters? Im jus going to to prob jus drill out the stock but its b great to habe backups. Thanks for any info i guess my main wuestion is why does the stock main look long like the idle but reolacements are all short?
