Kind of wasting your time even bothering with the different header then.
I had a header wrap for almost 8 years and no problem with rust. If you are going to leave the airbox stock dont bother with a jet kit. All you will end up with is a over-rich plug fouling cylinder washing fuel using bog machine. If your machine sis out in the rain than i certainly wouldnt recommend wrap. I am pretty sure the heat in the exhaust keeps this nice and dry. Just my 2 cents worth!

And you live where.... that gets how much rainfall anually, with an average humidity level of what?... and you go riding in the rain how often?... VS. where the original poster lives?

As for the rest... I think Teddy pretty well covered how wrong that was....

Incredible arrogance in a forum full of people well versed on this specific machine.

Where i lived back then was Iowa. I certainly appreciate your arrogant comment, I like it when people speak their mind. I have experimented a little on my own bike with the dynajet kit that you all say doesnt work well with Kat's. Also that K&N's dont work well. Not sure what level of experience you have with intake velocity during valve overlap, and effects of open exhaust and tuning but it appears as though
i may need to move to a group that does more than just jet kits on stock bikes. My apologies toall did nt mean to offend. This is not my first rodeo!

Almost forgot to add about a carb article i read on here stating that you cant ruin an engine from jetting too rich, cylinwer wash? raw fuel in the crankcase cutting bearings? rings eaten up from cylinder wash? All I am saying is there is a lot more to tuning an engine. Not trying to be a know it all, but if what youre after is performance and you are going to dive into a stock machine, theres more to it than sticking on a loud exhaust and thinking its faster because its louder. Last post from me which will make you happy! Good Luck and maybe we will meet at the strip or on the track someday.

There's also more to engine tuning than slapping on a Dynojet kit and some K&N's....... If you were really concerned about running too rich, you'd think twice about that goofy taper on the Dynojet needles. I wish I could have met you at the strip, when I had a running machine.

If you assume this group does strictly jet kits on stock bikes, you may want to take another look around.

Tchau!

looking forward to it

You know my intent was nt to get intoa pi**ing match with anyone, i love motorcycles just like the rest of you. I tuned myy dynojet kit with a sniffer and a dyno where i work. I certainly realize that everything we discuss is subjective
and we all have our personal preferences. Thes needles are stepped for progressive enrichment until the main jets take over. Mine runs great and if you prefer the Ivans kit I respect that. Ive built quite a few engines over the years, everything from cylinder porting and polishing, degreeing cams and tuning by cylinder pressures.
I think that I have certainly have earned the right to comment on jet kit tunung.
Great discussion though. And i respect everyones experience with the Kats thats why I joined to learn a little about what you all have done with your machines.
Truce Man!

I run 87 GSXR 750 cams, Bandit 1200 header, no mid-pipe or muffler, and a Factory Pro jet kit and I still have the stock airbox and stock air filter. I guess I'm wasting high-11 seconds at a time.

Granted we're talking about a Pre here and I have a Post.....Anyway, point I'm trying to make is trust these guys....they know what they're talking about.

I was looking at putting different cams in, are the 89 and 90 the best to put in?
Thats pretty respectable times. I ran a 91 zx7 back in the early 90s and if i recall i think i ran 11:17 at around 122. you have a pretty impressive list of vehicles up there. When the hell do you find time to maintain them all? After looking around there are some pretty interesting bikes on here. I am liking my cat more and more every day. At 42 its a great bike ergonomically.

89 GSXR750 are the most aggressive Suzuki cams that will fit in. 88 GSXR750 cams have a slightly less aggressive exhaust cam, but they're much easier to find (as all of the Katana 1100's used identical cams to the 88 GSXR750). Pretty much any cams from an oil cooled GSXR with forked rockers (4 lobes per cam, instead of the 8 lobe cams from a shim model) will work, and will be better than the kat cams.

BTW- This is my last Kat. I'm in the far lane. [email protected] Sorry about the quality!

I used to run in Illinois, Cordova, Byron, Great Lakes Dragway in Chicago and Earlville Iowa. Thanks for the info, we have some great salvage yards in Phoenix, guess i will go hunting. Thinking about a 771 piston kit. Dont want the 13:1, hard to find a 12:1 kit. I will let you know how it turns out. Awesome drag videos right up my alley!!!

Not to step on any toes here... I realize an inline four moves a lot of air at high revs but in comparison with my old v-star 650 and my vtx 1800. The total air filter surface area on the kat 600 is probably twice that of the v-star 650 and close to equal that of the 1800. I could see where there may not be a need for an aftermarket filter.
