Worth it?

I was going to get an exhaust sooner or later. And I figured when I did I would be getting pc3r, fans, etc.

I guessed with install the total would be between 1000 and 1500.

Well the racing season is over so THE mechanic is back, (worked on Hayes attack suzuki superstock motor and opie caylors motor/sponsorship).

I asked him how much to install A muzzy kit. He said he would rather not. He felt he could build a more reliable motor.

For 1500 he says he can get 10-15 percent increase in hp.

For 3000 dollars he will get 20-25% increase. He says that is the best he can do with very mild boring, he does not want to do any major boring or displacement increases for reliabilty reasons.

I figure 1370 muzzy gets 210 hp If you take 175 as hp with a pipe(I think they run theirs with a pipe to produce those numbersI could be wrong though) that is a 20 percent increase.

So with pretty much the same displacement as stock I should be getting 195 hp or so with out the pipe. Plus say ten more when I finally get a pipe.

DO I save up and additional 1500 or just get a pipe now and wait another year or so?

I dont know how I am going to decide, god knows I can not control the power I have now. I will someday get nitrous but not really interested in it right now, I want serious all motor power for some awful reason. :twisted:

Why are you guys so hooked on more power and speed?

You remember when you was a little boy and you played with little girls and now as a man you play with women? Somethings you just won't go back to after you ride a ZX12R.

I can't see how for 1000-1500 with parts and labor he can get 10% more. Maybe he has a secret way of plating cylinders after boring that don't cost nonthing.

I checked into big bore kits and the small big bore kit runs close to 1500 for parts alone. about 195hp

The big kit runs almost 3 grand and its 225hp I have no current ref but I'd think the price has not dropped.

Doing the mods in this site and running cam2, degreeing cams you could change power to show up top and gain 10-15% on good air day.

Maybe he's shrinking the size of the intake ports to increase velocity/horsepower. This "secret" is really starting to take off. People are getting BIIIIIIIIIIIG gaines from microporting. A little JB weld on your ports and BOOM! About a 7-10% increase in power.

Well see this "new" technology in stock sportbikes in about 3-5 years I bet.

Big HP from smaller intakes? Sounds like some more of that Motoman crap to me.

Close up your intakes and you'll get more HP alright...at 5000rpms. But it will choke at 11,000rpms. You might as well bolt a 600 head to the 12.

Im with workman on this one... Air+Fuel=HP... Fuel-air=rich condition... especialy at higher RPMs... maybe im just old school in my thinking but porting a polishing a head has ALWAYS posted better HP numbers, for me... However I have heard alot about smaller exhaust tubing leading to better torque.. but at top HPs loss.. :twisted:

Well see this "new" technology in stock sportbikes in about 3-5 years I bet.
We'll see!! 8) Velocity stacks have been used for many years to produce an increase in the speed of the air coming in. Don't know if it's new technoligy, but maybe refound. I actually installed a couple of stacks (28mm) off a YZF onto my RGV (32mm carbs) and went up in jets size by reduceing the inlet. We'll see. 8)

Seize the day.............live richer tommorrow!!

I know he said he would be porting, and he said he would be messing with the angle of the valves. removing counter balancer.

Most of the money for parts, he is taking the stock part and having them lightened balanced etc. He is also adding some total seal rings to lessen the amount of blow-by.

The labor part goes into finding the right angle for the valves and right valve springs etc. and installing and removing the engine.

I dont think he is kidding/stretching about how much power he can find. He is attack suzuki's engine guy.

I am trying to figure if this will be a better street bike than say a 1317 or 1370. I know alot of people use those for the street but I remember reading that they run hot in traffic, (as if the stockers dont run hot enough in traffic. ). A pro for the big bores is the gain in torque, a pro for his mods will be the bike wil probabl become more like an 00 or 01 with a very quick revving motor with a sharp peak at the top for hp but probably losing some torque down low.

It is such a hard decision for me at least, both are definetely good options, price wise they are roughly the same.

well he must be working on the cheap

i would also want to know in specificity
EXACTLY what he is going to do....

the EXACT protocol he is going to use

reasons being
if he is going to bore(???) your existing cylinders
is he going to replate them...??
what type of pistons will he use.....aftermarket maybe???

& the 1 that really gets me
how is he going to change the included valve angle of the 12 r head
or are you talkin about getting a 5 angle valve job
(big difference )
which please...?????
i think that he wont be able to change the included valve angle !!!

if you are going to modify your engine
a reasonable expectation of HP is to be expected
thats a direct result of his expertise/protocol

he should be specific
in what he's going to do & how
the dyno tells you if he did it correctly
& time will only tell if reliably
not $$$$





good luck

Removing the counterbalancer will only net you 1-2 HP. Is it really worth the extra 1-2 HP on a street bike considering the vibration? Not to mention the extra vibration tends to shorten engine life.

I agree, on the counter balancer thing, but he is having the rest of the parts balanced so the counter balancer should become less of an issue.

I will check with him to see exactly what he meant by change the vavle angles.

I will also try and get a list.

(maybe I can even get him to write some if it does not give the increase I promise it is free!) just kidding He has access to a dyno So I am pretty sure we would run a before and after.

I will try and get more info tommorow.
