    Twin pipe XPL jetting questions

    Hi, setting up a 02 xpl with twin pipes, miller 49cc dome head with .070 squish, advent ignition. I will be running stock carbs for now due to the fact i have enough $ invested in this build and do not race. I am looking for some suggestions for jetting. I have removed the acc pump. Thanks

    I had Highs 177.5, lows 100 no pumps. Its gona load up if idling too long though. With those pipies you have to give a lot of juice at low revs.But they sing at 73-7500.Make sure the prop isnt loading too much.

    I have a set of rinaldi cages, but the petals are bad. I will have to get some new ones. Think i'll set them up with 100ls and 175hs to start out with. Where should i keep my EGT's?
