What jetting and settings are people running on their Tubers with a mikuni carb fitted  What main jet pilot jet air screw position needle type needle position accelerator jet nozzle size I have tried a few settings and can't really tell any difference  I don't think this has been really covered and would be interesting to see what you are all running

I think that the attraction of the (Buell specific) Mikuni 42 is that you just bolt it on and it works. I guess that most owners have been pleased with the performance of theirs straight out of the box and haven't had to inspect them too closely. |

Wow, completely different to the link I sent you (wasn't saying it was right BTW). Maybe we should document your findings... How did set it up by the way? Dyno? Plug chop? Arse dyno? |

The standard HSR42 (for Buell) kit comprises 160 main 20 pilot 97 needle Is my understanding from previous conversations I have had with those who would know

That's interesting,keep em coming A #20 pilot might explain why i'm 2 1/4 turns out at my #25 pilot (my kit came with a #30 pilot  )I do have a spare 97 needle and a #20 pilot What does reckonMy carb came with a #70 accelerator pump jet and that seemed way too much too |
