Shorter Slow/Pilot Jets
 
I just received my #48 slow jets from jetrus today...I order the Genuine Keihin slow jets....they are much shorter from top to threads....compared to stock. From the threads down they are equivalent to stock jets....Are these ok to run???? Has anyone has seen this before???

All help is appreciated.....

Did you get a series "21" jet?

Not sure exactly what series...I went to jetsrus.com selected vtr superhawk and bought the GENUINE Keihin slow jet size 48 according to jetrus I should have purchased the OEM equivalent ....I believe the OEM are Series 21

This looks like a good topic to me. What happened when the new jets were installed? Run differently? Improved low end?
