OEM petcock. Is there a difference?

[razor02097]

Yesterday riding home the GS had an unexpected sputter... I had to turn the valve to reserve at only 80 miles! Usually I can get to 110-120 miles before reserve. I recently replaced the petcock with an OEM NOS unit. Is there any differences between petcocks? My other theory is I didn't fill the tank all the way after replacing the valve...

I don't know if the part # was superseded because I got it from bike bandit during the 15% off promotion.

The amount of "reserve" left in the tank will depend on the height of the pickup tube on the petcock. Did you compare the new one with the old? Were they the same height?

Some petcocks have reserve kick in at higher fuel level; my original (I think) petcock forced me to "res" spot at 1/3 tank if I was in hilly terrain. Replacement unit will run to 1/4 level with no problem.

I didn't do that I know I should have... I guess I will have to pull it back out to compare...
