My bike came with the K&N installed and the paper filter in the box. K&N's are not the best for filtering - read the Motor Oil thread and you'll find a significant difference in oil contamination with paper vs K&N. On another board someone noted that the bike will run smoother in the lower rpm range with the paper filter, so today I installed the basically new paper filter today. Guess what, the bike ran smoother in the 1,500 - 3, 000 rpm range, maybe not quite as snappy in the mid to upper range, but it still lifts the front wheel with ease in first and second gear.Keld said:WHY??????
If it's that lean, you'll know by hearing pops and backfires upon deceleration and some very heavy lean-surging.wbeck257 said:being too lean can cause detonation... that'll cause some damage.
Well, a normal motor usually makes a "brop brop brop brop" type of noise when engine breaking. It's just hard to hear because of the stock exhaust. If it's just loud tones of deceleration then I think it's normal. I usually can tell, mostly with Harleys, when someone tossed full pipes on there and didn't re-jet. When they downshift of brake, you can here a loud and obvious backfire. My freinds and I usually turn to each other and laugh.knowpain said:I get popping from the Arrows when engine braking. It is a rythmic pop with no loud backfires. I think it is normal.
Hehe, exactly what I said, but nobody seemed to notice.Norm said:Trying to read a plug that's be idling is a waste of time. For any meaningful reading, you need to do a plug chop. Unleaded fuel also makes it difficult, you can't tell much without looking at the ring at the base of the insulator, that's why they make those cool looking magnifiers (kinda like the type your doctors uses for your ears). Reading plugs is pretty much a black art.
