big bore kits??
OK people I need some insight... Plz only people reply who have tried themselves and are in the know... I find a lot of people who just like to give an opinion reply way to often....sorry
Anyway I have a 04 zx12 that I drive on the street as well as drag race. when racing the bike its lowered, stretched, geared, air shifter and slick...
1st question: I run a 7 inch slick.. Is this overkill?? can I get away with a shinko or m/t shootout? If I go with a shinko will I get more mile per/hr than with a slick? If you suggest a shinko is there a particular one I should go with, considering I would use that for drag only not street use. I have a seperate rims for racing and then street. Would like the stickiest one available.
2nd: Im thinking of going with a big bore kit. From what I can see a 1270 kit seems about the best solution for street and drag. How dependable is it for street use and how much real power extra will it make? Also I have a full titanium muzzy pipe, pcIII, if I add the 1270 kit how much rear wheel should I expect?? and would a shinko still hook up with it???
3rd: If I go with a tiger tail, should I.?? and will it allow me to lower the bike much more than the stock inner fender and still be able to use it on the street?
thanking in advance

190 +- STD HP DM I still have the article in the Magazine where You Installed the kit and got about 180+ SAE HP If my eyes have failed me or that was a one off Magazine let me know! I do know for sure the Torque always goes up! Two different Bikes two different Dyno's both 2000 ZX12's Both 1270 Kits and both made over 100 in Torque and between 177 and 181 in HP (SAE HP)

oh man! Meyer and Hill on big blocks! I have an 02 ZX12R, full stainless muzzy and PC3r, street use only. I'm looking at a used 1270 kit, but am very apprehensive about buying a used kit without knowing what to look for. Any advice would be appreciated.
Also, I'm wondering if having the dogs undercut would be necessary for street use?

1st: slicks are only really needed if you're running a wheelie bar. you need the extra traction to keep from spinning too much when the weight shifts to the bar
2nd: for better power on the 1270, get some headwork. stock, the head makes plenty of torque in the lows to mids, but for hp it needs to breathe up top
3rd: let me know how that works out for ya. i'm looking at them too...

Yes ,Vince that was accurate but was early in the development cycle. It seems to me that several users have reported high 180's over the years and a few 190's (with cam nice head work etc.) If that's not correct , I apologize for my optimism!
I'm afraid I may tend to state what's possible, rather thah what "just happens" !

let me try.
1st.. yes slick is overkill, shinko ultra soft great all around, MT shoot better hook but much shorter life. With two rims, pick your favorite street tire and a MT for the track if your can trailor to and from the track.
2nd 1270 without the base gasket is good for 3-5 mph in the quarter and about 1.5 tenths.
dunno hp numbers.
3rd tiger tail gives you a little not much but won't rub a hole and burn your CPU wires.
no problems on the street.

No disagreement here! That is why Apples to Apples need to be compared. I to have seen high 180's and low 190's but they were STD Numbers. I KNOW that high 180's in SAE is possible, just personally never saw it! Of course most important is how it was installed (The rings are a Witch to deal with) and even more important is the Initial break in to seat the rings! Done right great kit and good running! DOne wrong you may have less than you started with!
Like I said, no matter what they did or did not do, They ALL Make more torque! 2 to 5 more on all of the ones I have personally seen on the dyno.

Put it this way Vince....the 1270 properly installed w/o base gasket is easily worth 20 h.p. and 15 ft. lb. TQ. STD, SAE, or uncorrected! Before and after, same dyno.
Of course you will need to feed the fuel to the 1270!
