Cam degreeing
Hi guys.I haven't posted on here but been around the forum for quite awhile. I was looking for cam numbers to degree my stock cams to on my 2000 ZX12.I plan to occasionally drag race it and ride on the street.It's not my only bike but I'd like to keep it as usable as possible for everyday reliability.That's why I'm keeping stock cams and springs.The rest of the bike is full Muzzy stainless exhaust with oval titanium muffler,K&N filters,PC3.
Thanks for your time and input.
Mike

105 105 is a good place to start

Thanks Scott.
That's actually where I have them on my ZX7R.I thought that might be a good starting point but I wanted input from all you guys with experience with these beasts.

Could you guys give me a little advice on the clutch set up.I'd like to have it live as long as possible under dragstrip use.ANY help you can give me with it would be awesome.

105/100 gives good torque. If you do a search you kind find all sorts of data on this subject in bikeland....

From my understanding all stock oem clutch parts are the way to go, Nox is the clutch man i believe, Most important thing will be to double check ur stack height, i m at the tall side of the specs n havent had ne problems wit slippage, i also have heavy duty springs from schnitz racing. If u dont have a repair manual, get one, most of what i've seen is by the book as far as maintenance, torques specs n etc. I'm sure u can find a free manual on here as well

Thanks for the quick reply.
I've got the manual and understand stack heights,etc.Are the 2.0mm steels still the way to go?I'm wondering about the clutch hub.I've got the stock 2000 hub in it right now.What's the better path to take?Install a 2002 or newer hub and drill it for clutch plate oiling or spring for the Muzzy hub?With everything installed am I still unable to hot lap this bike?Are there ANY clutch fixes to enable it to be run with short cool downs or do I need to plan to pull and oil plates every pass?
Thanks for the help,
Mike

Do the Muzzy hub. It's completely de-bugged and reliable. Follow the directions.

do a muzzy hub, or modify one to do the same thing
yes 2.0 steels
stock fibers
being able to hot lap will depend way more on your launch style than whats under the clutch cover

I'll be hauling the bike to the track in an enclosed trailer so as to not unnecessarily beat on it on the track days.I'm figuring launch RPM to be 3,800 to 4,400 range intially.I'll also soak the plates before the first pass and give lengthy cool downs until I work out what it can take.Does it sound to you all like I'm in the ballpark?

gearing, WB, weight?
2 step?
lock up?
no need to soak, just get them a little wet with your finger when you put them in

I have an mtc lock up for it.Still new and in the box.After looking at the video of your dad's bike on the two step,I have to admit I'm liking it.I have no idea what's involved in setting that up but I'd like to learn.
Wheelbase: 61 inches
weight: unknown bike is stock bodied with muzzy exhaust,I weigh approx. 200 suited up.
Gearing: 16fr,46 r

I'm pulling the head and oil pan this weekend to check the engine over.I don't believe anything is wrong with it but I want to be sure I have no scored cylinders or wasted bearings at the start of this project.
I have a spare head and stock cams in a box.Is it worth changing the intake cam right now since everything is going to be apart and I have the parts.The labor is also free.What kind of actual gain can I get out of the swap?
Currently the engine is stock.
Thanks for the help,
MIke

the 2 step is very agressive on the clutch, im not sure if i would want to use one at only 61 in wb.
to get a lock up to act like that you need to run really light static spring pressure and just enough weight to hold the mph.
if its mostly a track only bike and you have an air shifter i would suggest going up 1-2 teeth on the rear to gear it even lower, easier on the clutch, and feels like more Tq.
i cant say for certain on how 2 intake cams will work as i did that allong with a bunch of other things one winter. you will probably need at least 1 adjustable cam sprocket though.
something else to get your clutch to live longer is a properly working rear suspension with a decent amount of squat

I've got an air shifter and re-gearing is no problem.Bike still has stock shock.I'll probably have to make do with that until the end of the season at the earliest.Just can't afford an Ohlins or Penske at the moment.I have adjustable cam sprockets too.I'm an aircraft mechanic and have no problem getting into the guts of a project like this one.

I've got adjustable cam sprockets for it and I'll be putting the cams in it this week when I go thru the engine.The gearing change won't be an issue either.I do have an airshifter on the bike as well.I'm 99% positive I'll be calling Schnitz this week to order the deep first gear for the 12,too.
Unfortunately I'll be using the stock shock for at least the reat of this season.I just can't afford a new shock right now.So I might be fighting the suspension a little.

Ive been 8s on my stock shock. I have a revalved resprung shortened shock to try this yr after i get my bike finished.
i set dads bike up with a stock shock that had the same treatment for this season. Trac did the work, way cheaper than a complete aftermarket unit. its working pretty good, a few more tweaks and i expect a lot better ETs

That's good to hear.I really appreciate the help with this.I'll be trying to get the bike together and running by this next weekend.I don't know if it'll be done but I'm gonna try.I'll keep you updated with what I find in the engine and how everything goes together.
Thanks again for all the info.
