SepiasSoul I haven't jetted my bike, I've thought about it but haven't done it. I still have the stock headers and a crappy slip on. I'm trying to figure out if the 89-96 FZR1000 will fit my bike since the V&H manufacturers part numbers are the same.

Z_Fanatic Does your bike have full system exhaust and jet kit as well? Airfilters cost about $25.00 for my bike through bikebandit.com or local dealer. Air filter for older bike should be cheaper, for example, for my '90 FZR600, it was $10-15.

SepiasSoul My bike loves the gas to and hates mornings. It took me 15 minutes to get the idle right this morning and it hated the choke. Hopefully my V&H is the problem with my bike, its being replaced very shortly with either an Akra(fingers crossed) or a Micron(any opinions on microns?). I've never paid more than $25 for my air filters so I'm guessing their either a really cheap aftermarket, or since they were put in by a guy who drag races bikes constantly, its the OEM.

Lord Duckhunter There is some science & art to installing a jet-kit properly.

However a properly jetted bike will be a tad bit cold natured at first. As the engine temp gets hotter the A/F ratio gets richer so you jet them to run properly at normal operating engine temp. This means that when the bike is cold it will be a little on the lean side & requires the use of the choke to get it started & then as the engine comes up to proper temp the leaness goes away & the mixture richens up to where it should be optimally.

But as you described if you don't do it right it just makes things very sluggish or causes hesitations etc...

Z_Fanatic Yeah, my wallet wouldn't justify paying $50-70 bucks for an air filter, which wouldn't last as long, and isn't as efficient doing its job- filtering.

I am more of a mpg = performance guy, that's why I didn't even go for aftermarkets gearing to save some gas. No doubt it would also throw off speedo inaccuracy even more.

I had a jetkit and full vance & hines exhaust installed in my old FZR, a monkey must have done it. Because the bike was horrible to start, and after 1/2 hour of choke and throttle, it would sip fuel like gatorade while riding. Even having it as a first bike, I could feel in fact it made the bike slower. The bike was asthmatic constantly.

After I got my SV and F4, I never once had to use choke.

Lord Duckhunter Simply put you will never go wrong with OEM filters.

Sometimes aftermarket high flow filters do work & offer appreciable gains, most of the time they hurt the performance more than the help it.

SepiasSoul So your vote is OEM filters, even with out a jet kit or FI system?

SepiasSoul Whats wrong with K&N filters? I dont have them in my bike, but everyone seems to hate them and I'm curious as to why.

Lord Duckhunter It's kind of a tricky thing, cause you have to listen to & feel the motor to get it right. You are basically looking for a good healthy lope to the motor without it being a fast idle kind of thing...

There is a pretty wide range of adjustment on the screws that will work for you even if not optimal, but if you go to far one way or the other then you will start to notice problems like hesitation at very small throttle openings, or a miss when you blip the throttle or even a strange dip in power when you upshift through the gears just as you crack the throttle back open etc... If anything weird starts to happen at very small throttle positions then you've probably gone too far on the adjustments

Oh & also stay away from K&N air filters on that bike!
