Can anyone tell me what size this jet is?
« on: April 29, 2019, 10:13:51 AM »
So this jet this jet was in my 750k7 from Mr. PO because of the breadbox filter and no-baffle exhaust on it.  The whole bike was fine until about 2 weeks ago, and I've fixed everything wrong (flout needles, accel pump, points, coils, plugs) but then it started to run too rich.  I had to put in some 110s from my old rebuild kit, but now it runs too lean.  Trying to find out what size this one is since it doesn't follow the standard numbering of keihin jets.  Thanks

looks like it reads 122.5, but that isn't a stock Keihin jet so how accurate that might be is questionable.

+1,

If your jet number is equivalent to .1225 a #31 drill bit blank gauge will pass through with no resistance. A #30 will be a no go, if you have a friendly machine shop around.
