stock Jet

Comments On Oct 06, 2014:Sometimes its best to replace the stock pilot jet on a bike you bought used. In this case I needed to go back to the stock size. Never hurts to have some new bronze in your carb.

gets the job done

Comments On Jul 23, 2014:Needed to go up one pilot and bought a 42. Upon opening up the bottom of the carb the previous owner had already installed a 42. Paid for shipping the second time to get a 45 which works great on this bike with my modifications to the box/pipe/filter.
For the price I should have picked up a few the first time to save shipping. I did this with the main, but failed to do it with the pilot. You can buy two of these for the cost of shipping alone so it just makes sense to get more than one.
Easy in/out, works flawlessly.
