dynojet kit
ill soon be purchasing jardine hight mounts from a friendly forum member, and i will proceed with purchasing a new k&n air filter and a dynojet kit in an attempt to pump up the performance of my bike ever so slightly. this may be a dumb question, but i just dont know as much about street bikes as i do dirt bikes. do you have to take the carbs out of the superhawk to install a jet kit? if not, is it worth it to keep the carbs in the bike while installing the jet kit? thanks guys.

You must pull the carbs to install a jet kit. If it was me, I'd install the cans and see how it ran first. Past that, I'd lift the carbs up off the manifolds so I could access the vacuum chambers and shim the needles (no need to detach everything else from the carbs).
Even if I was doing a full rejet, I'd stay with the original air filter.

im going to get a k&n OEM filter replacement. its what dynojet suggest for a filter anyways. ill definitely be throwing the cans on first. if i can save the money of not having to rejet then i will. im probably going to remove the PAIR as well, so i might just end up doing it all anyway. we'll see though. thanks.

I've got no experience with the K&N on the VTR. I do have cans, dynojet kit and tried the BMC filter before going back to the oem one.
Based on stuff I've read on old threads I'd guess you can install cans without rejetting or at most a needle shim, but if you go with the K&N you'll pretty sure need to rejet and be lucky if you get it right the first time.

That's the smart way to go, one step at a time. It seems to me that unless you install a full exhaust system, or MAYBE race baffle cans, you probably don't need to rejet. Maybe shim the needles for throttle response.
I know ten years ago, when people (like Erion Racing) were building 130-150 horse power VTR racers, they reported than NONE of the aftermarket airfilters they tried (K&N, BMC, BMC Race etc.) helped to make any more power than the OEM one.

Speaking of Dynojet, I saw this Dynojet Power Commander 3 USB, but I thought this item was not compatible because the VTR was not fuel injected. Can someone clear this up?

Ordered me one, installed it and the bike goes like never before. The big bonus is you can adjust the unit to suit conditions without having to swop jets. Just the Turn of a screw on the side of the airbox, and the bike is richer or leaner.
Believe me it works.

The DynoJet Jet Kits are pieces of crap. Ask any experienced mechanic and they will agree. The Flo-Commanders are very nice. I've been looking into one for awhile now. Everyone I know that has one loves it.
...I'd say throw the cans on...but leave the carbs the way they are.

I had the DynoJet Kit in my SH. I thought it ran great until one of the mechanics at my shop (has been working on Honda's for over 50 years) told me to let him rework my carbs. I gave him the bike...and when I got it back...he handed me the jet kit that had been installed and told me not to worry. I hopped on my bike and DAMN...it was soooo much better. No jet kit....BMC filter....Two Bros. exhaust. Not sure what all he did...but it can be done without a jet kit. It just takes the right mechanic who knows every little thing about bikes.
My SH runs like crap.

"I had my local guy keep y bike for three days. SHe screams like a raped ape. Pushes 125 HP on the Dyno and 75 FT lbs of torque after 3200 RPM constant. It is retarded the amount of power she produces..."
he did a whole lot more than just install a jet kit to get that kind of power out of a VTR...

Ok Ok Ok.... I will find my Dyno slips.. Just need to rememeber which foot locker I put them in. As soon as I find my dyno slip i will post on here... I also have a K&N air filter a full TB exhaust. I really need to check the CCT's cause I'm not sure if they have ever been replaced... Hey does the front on go out from lack of oil from doing wheelies? I know it sounds stupid but I normally hang em for a mile or better... Is this not good for the CCT in the front cyclinder? Please advise and I'm getting to that Dyno slip.
