Yea and you notice he isn't on here explaining himself someone should pm him n see what he says, it sounds like he's going to lose a lot of buisness from this

I made a post else where asking about who should do my motor work. I said I was looking at FlowTec and (Project Blaster, Factory 7) I noticed replys said Kennedy.... is he Project Blaster, Factory 7.
I notice on this post people are saying Kennedy. These pictures his work?

hey lonewolf...in your other post i made a comment about having flotec do your work for you cause i have seen pics and he's good.....this is the reason why i reccomended flotec to you !!..lol..those p&p pics here are terrible ..
Mrbrocco...did ya get it together yet? how was the turn out ?

yeith luckily mine doesnt look that bad.
i know he said he doesnt polish the intake he roughens it up because it provides better mixture before entering the cylinder

well my thoughts are that i try and stay out of these kinds of situations ,frankly its none of my business i try to respect to the parties involved ,ill just say hopefully theres some resoultion for everyone affected in the matter
The intake and transfer ports are never polished. There are two reasons for this.
1. The fuel will stick to a smooth finish; this causes fuel/ air separation
2. A smooth finish will cause turbulence. Why are golf balls rough? To help eliminate turbulence. What does turbulence do? It causes drag or friction.
The exhaust port is the critical port; it sets the entire engine up.
So why do people focus on the intake port so much; they simple do not have the experience to know better.
The paint in the intake is not going to affect the power; raising the intake window to the boost or 5th port is not going to increase the power output as well.
I could have sand blasted the intake and then cut the intake; would you have gained power; no. It would have looked better; do you want a intake that looks nice or a engine that makes twice the OEM power. That set up with a Shearer pipe and 35mm carb, and timing set at +4 is good for 33hp
The cylinder head is not just milled; it has real combustion chamber design. Look at it again; hey it’s got a squish band cut at the correct angle and length. It’s even got a tight squish clearance, not the .100 to .125 inch clearance from the OEM.
The couple of people that said; you don’t know until you run it, are correct
How would someone know were the exhaust and transfer timing are without measuring it, or placing a degree wheel on the crankshaft? That’s the critical numbers.
The spark plug thread hole; I can say I honestly do not know. If I would have pulled them out I would have taken the 10 minutes to repair the threads.
If you want a polished intake; have someone else do the work. If you want a cylinder/ cylinder head design that makes big power through out the entire RPM band; then send the cylinder/cylinder head my way. I will not waste my time polishing anything; but the exhaust port. That’s the only port that needs to be polished.
When the cylinder was sent to me, the cylinder sleeve was cracked between the main and secondary transfer ports; I gave him cylinder that was not cracked.
If you want to dyno that set up on your blaster; you’re welcome to stop by. If that cylinder/ cylinder head design does not make 30+hp; then I will reimburse the fuel cost to get here and back.

i also wanted to add that FLOTEK DID NOT polish my intake, i did, thinking it could only help, that pic started a war on another site, i was pretty much told the same thing, as in kenndys post about not polishing the intake, and just polishing the exhaust.
kennedy, im pretty sure that most of the members that want ur work have no idea that porting pics mean nothing, thats why they PM you, u do know ur sh*t, but IMO, isnt presentation also a big part of the sale, honestly what would anybodys first reaction to a port job pic like that be????
and just so everyone knows porting pics dont mean sh*t!!

pittboss45, what I was getting at was who cares what it looks like. does it work? I remember in the 80's I was going to Daytona to road race, I had a 2 stroke and when I got my barrels back from the porter I thought my god they are ruined, put the bike together and about pooped myself, scared me to death, fastest thing I ever rode.
I agree !With all the people on this site you are selling a product "kenndy power" at all times,in your post ,or in your products presntion. Looks are every thing.Even if they dont make power.Looks can make or brake you!!!
i agree w/ the things that gonzo is saying.....i don't think this brocco kid knows a whole lot about engines.
i'm not a 2stroke genius by any means, but between my blaster and my 4stroke street bikes, and all the time i've spent talking engines w/ kennedy on the phone (he's become a pretty good buddy to me over the last few months), i've learned enough to know that taking off too much on a port/polish job (either on a 2stroke or 4stroke) can be a LOT worse than not takin off enough.
brocco, unless you're running a 35+mm carb and ported reedcage (or a vforce2), you wouldn't benefit at all from having the intake ported any more than kennedy's standard. think about it, what good does it do it drink from a bigger cup if you're sucking through the same tiny straw anyway?
i see that you're plannin on getting a larger carb and a-m reed cage. well, if you're running a trail port job then kennedy's intake design will flow plenty. now if you wanted a drag design and you got that intake, then maybe i could find fault in it...but for a trail port design, esp since you're not running a drag exhaust, i think you're upset because you didn't get what you were expecting, but do you have a degree from formal education in this stuff? how many years of experience do you have working on engines? how many thousands of dyno runs have you pulled?
these guys (not just kennedy, but all the builders on this site that help us out and make this forum such a great resource; pittboss, flotek, wildcard and others) are far more educated than you or me. and they can usually justify the way they do things w/ some very reasonable logic.

Kennedy, Nice work or not, presentation plays a bigggg part. Its not about you making big power, its about you making it look that way.
So if it looked like it was going to be really powerful, but then it wasn't at all, would you be satisfied??
