OK, so I cleaned and re-oiled my K&N in my 5th Gen VFR800Fi this weekend, and the first 1/2 tank of gas milage was unbelieveably low. Some background:
- bike has 30,000mi, 6,500 since I bought it this May
- was getting roughly 200+/- per tank (refilled usually about 4 - 4.5 gallons each time)
- just did an oil change with Seafoam
- also put Seafoam in the gas tank which was 1/2 full (w/suggested ratio of fuel to Seafoam for fuel level in tank)
** cleaned and re-oiled K&N air filter. Put on about 4-5 layers of oil since I was not sure how much to use. Let it dry before starting bike.
Rode it on interstate during trip at 70-80mph for 2hrs and watched the gauge just go to nothing, quicker than normal. Re-filled tank. Not sure if mileage back to "normal" yet.
My question is -- can you put on too much oil on a K&N? How much do you put on the filter anyway?
