They wouldn't have to change any tooling. I believe the cams come in to the factory as cast blanks. An operator would put the cam blank into a machine that grinds it according to what a computer tells it to. So they should easily be able to machine a different profile by simply changing the specs in the computer.

Well thats kinda what i meant would they do it just for the bb kit. I guess the one way to find out would be to measure a stock 1700 cam and a bb cam and see if they differ.

1700 cam

I have the 1700 cams (so far as I know they are the same cams as the BB kit) in my 1600 motor.
what I observed when I asked the dealer if they could get the parts was: they pulled up a screen (on the parts computer) that had the BB kit with part numbers. the parts numbers for the cams and the clutch springs where taken down and ordered. I will have to look but I must have a copy of the quote somewhere, it may have the part numbers on it.

I do have the original 1600 cams wrapped up in the packaging the 1700s came in (I assume they are the same as what is now in the bike)

When I get home I will try to see if I can locate those pn's. that will provide 2 out of the (maybe) 3 options here.

you need the storm cams part numbers to compare with since the storm is a factory 1700. But you will have to call a dealer and see if they will get you the p/n for the storm. Bike bandit uses thier own numbers, but they don't even have the storm listed anyways. This would be interesting and finally give us a definitive answer. I'm very curious myself.

Interesting on the air filter rubber strip Daz. I took mine off 2 months before my brother without him knowing . For two months he couldnt keep up with me off the line or from 30-100. After I did his and he hit me for being a git , our bikes then went back to being identical in acceleration and top end .

I used a home made seal actually, and i ordered a new one i have yet to get. So i may remove it before i put the new seal on and have a few rides w/o it again to see if it still seems like the top end isn't that much better w/o it. If it still seems like way more low end torque and not a big benefit on the top i'll install the new seal. But the torque seemed thru the roof when i put my home made seal on there. I mean it really seemed super strong. Oddly it no longer does and i'm not sure if thats because i got used to it or because the adaption eventually screwed me out of it. I'll soon know i suppose. But i'm definately getting better MPG with a seal in place.

Yeah indeed mate all things need to be tested. Ill be interested when u get the new seal maybe theres a compromise to be had somewhere . My bro definatly noticed a substantial difference when we got back from the test ride he kept saying how he couldnt believe the difference . Luckily its an easy one to test by just slipping it back on on and off.

I do agree the top end is definatly better obviously due to the easier breathing but I havnt noticed any loss in torque down low but that might be just my uneducated seat of the pants evaluation.

Remember I have exactly the same set up as you with bb kit and short tors and the most important bit the blue white colour lol.

Keep us informed.

Yes, the blue and white is definately the best performance tweak there is. On a related and serious note, did you see that guy's black storm that he posted at the other forum that he had a white strip put on? I gotta tell you, thats now my fav color ! I always loved the black/white combo, but i didn't realize HOW much i would on the bird's scheme. Looks awesome, far better than the plain black which is actually my least fav i think. Only thing is, as much as i like it i would pass at tha chance to swap tank and fenders with him because black is the worse color once it ages. You can never get that new beautiful look back once it's been cleaned a few times and the scratches set in. Otherwise i might be considering having mine painted, thats how much i like it !

Just thought of something druade....you are running the stock #20310 1700/TORs tune aren't you? if so, try dizze's 1st tune, the one thats WITH cat. Thats what i'm running. It's pretty strong. Does eat more fuel tho, at least on mine.
