Has any run the 1570 kit in a street bike yet. I have everything and will be tearing bike apart when I get home from Iraq. Also what about the balance shaft eliminator.

Run the muzzy and carpenter 1570's on the street all the time. They will run warm and you will need to run daul fans pull 2 degrees timing and run mrxo1 fuel if you do alot of stop in go. Out on the open road they do fine! Remember you dont have to rev these motors hard and they will give good service life. They are by no means the optimum tour motor but if you keep the maintenance up they do fine for street duty. They are also very hard on rear tires. LOL If you have the the extra coin you will want a good head porter as these motors love better breathing.

Thanks, just with the standard bolt on stuff its hell on the rear already. I was already going to talk to my guy that ports my big chief heads for the outlaw 10.5 car and about boring it for me. you have any idea how much power the 1570 motors make. Well 16 days left over here on this trip so I can't wait to get this thing apart. I think after this the only thing left will be to put a voodoo short exhaust on it.

Outlaw105, I hope you will post pictures as your build progresses.....1570.....I don't need one , I don't need one, I don't need one...Ok, Maybe I do..LOL

I agree with Romans, a build thread is just what this forums needs, with lots of pics.

Muzzy claims 240 hp with his build which includes cams,head work,etc but i never had one make over 220 and this was with a carpenter motor. Don't put to much stock in HP numbers with the 1570 14's, the big numbers that matter are the
torque these things make!
The last one i did with bobs head,lightened/balanced crank, no counter balancers made 218hp and 152ft lbs of torque.
The bike runs 8.50's on motor with a 220lb rider that runs in bracket racing and the bike runs the same damn near every pass. Real consistent street/strip bike. I don't like to say anything negative about other peoples choices when it comes to their perf, parts but i have not had any luck with the ex system your considering on the dyno or track with theses motors! Breathing is something these motors really respond to and a sidewinder is the best,but not practical on the street for most. We have good luck with the AH and the new ct series shortmeg, the latter makes more torque across the rev band then even the M-14 sidewinder [IMO] the best sidewinder out that i use. Again nothing against your choice of ex,system' it just wouldn't be my first.

its been so long time working overseas no time for anything. Well finally took the bike to Adams Performance to have the 1570 kit installed should have it back by April.

By APRIL? DAYUM!

I'm running a 1570 with a garage ported head and muzzy cams. Like bill said, it makes 220hp. I can ride mine on pump gas, stock timing, single fan. But I also have a sidewinder, and as Bill said, its not the best street exhaust. THerefore i don't ride on the street much.

Balance shaft eliminators? NO! Not if you're going to ride on the street. Mine is HELL, it vibrates everything and makes it a very unpleasant ride.

Colby won't like it, but go with a competition cnc head/cam package and either 47 or 50mm throttle bodies. You will have to spend more coin, but they're making 254hp on a 1540. According to their predictions (they haven't tested on a 1570 yet) the 1570 will make over 260hp at the wheel.

BTW, my builder had my 1570 done in about a month. I know Adams is a busy shop, but april is a bit overkill.

Oh and unlike bill, i will tell you straight up.. brock's makes the most power, is the best flowing, and GOES THE FASTEST when it comes to exhausts. If you put that doo-doo exhaust on, you'll probably restrict your 1570 to about 180hp. That thing is junk.. in my opinion of course.

The head is going to carpenter. its a street bike so it wont see a sidewinder wanted to run their oil pan but you have to run a sidewinder so I guess the factory pan will have to get modified for clearance. Also got the muzzy cams. Thanks for the info on the balance shaft was going to have them eliminated. The April time was set by me in no hurry heading back to Afghanistan so was just wanting it back before I left again. Damn if only makes 250hp I'll put turbo pistons in it and hang a hair dryer off it. Kind of sounds nice 1570cc's with a turbo... Got me thinking now....

The 3 mil bore will never last with a turbo. Too much cylinder pressure you'll wash out the area between cylinders before you ever get full throttle.

With the carpenter head and muzzy cams, through a street exhaust you'll be lucky to get 220hp out of it.

Ok dont know alot about motorcycle engines but how can a stock motor with just some basic mods and a power comander make 200 hp but you add 200+ cc's and only make 20 more horse power come on I just don't think so.... If it works anything like stroking a big block then I would tkink it should make more power I was looking for more like 275 but like I said not up on motorcycle engines. I guess we will see just bought another engine so if this 1570 is a terd then it will be turbo time....

outlaw elaborate please what basic mods can get the the 14 to 200rwhp? thanks

Dude, I'm telling you because I have one. With that head cam package, Running through a street exhaust, you will be lucky to make 220.yes, you can make 200 hp on a stock size motor. No, you can't make 275 hp with a 1570.

Competition CNC did the head cam package for rickey gadsons 1540. You already know, there are things on that motor you and I can't buy. Comp cnc is making the MOST power out of anybody.

Rickey's bike makes 254 hp on race gas and a ti-winder.

I am telling you, right here and now if you turbo the 1570 it won't live through break in. The cylinders are way too close to handle the cylinder pressure of a turbo.

But hey, obviously you know more then I do. So build your 275 hp 1570 and then throw a turbo on it. Be sure to keep us updated. And after you ruin your block, let me know how much you want to sell your pistons for. Wouldn't hurt for me to have some spares.

OK please read again I SAID I DONT KNOW MUCH ON MOTORCYCLE ENGINES. I was just applying what happens with a V8 engine when you stroke one thats all. I was saying I was just thinking that the same theory would apply more cid or cc's you would think would = more power I guess I was wrong. but hey I'll see you a whole new motor. I just bought a new motor in Miami and already looking in to which turbo kit to install. So relax buddy I wasn't trying to say you didn't know what you were talking about. but tell me how can a 1540 make 250hp and a 1570 will make less and on my previous post I'm pretty sure all I said was that was what I was looking for not what it was going to make I have no freaking clue what it will do. That is why I was saying if it doesn't perfrom its getting a turbo I understand all about turbo I have a outlaw10.5 car 372in small block with a 114mm turbo hanging off it. SO yes I agree about the 3mm overbore not able to handle the cyl. pressure. So again that is why I bought another moter. So make me a offer for a Adams built 1570.

i dont want another 1570.

in case you were missing the main part, the carpenter head with muzzy cams won't make much power, ESPECIALLY through a street exhaust.

The COMP CNC head/cam package would probably make 245-250hp on a 1570, even through a street exhaust.
I'm sorry if i came off rude, i just don't think you're understanding what i'm saying.

The muzzy cams are fine.. For a stock motor, or for a 4 mil stroke/stock bore, or for a 2mil bore/stock stroke, maybe even for a 2x4 (although now you're pushing it).

If you go bigger then that, you at least need WEBB race cams. Competition CNC has WEBB custom grind their cams, they're specially matched to their heads. Their heads include a +1mm valve job, and a ton of other shi* that i don't even remember. YES they're very expensive, over $5k if i remember right. But as far as i can tell, its the best way to make big power from one of these engines. Colby was making 230(ish) in Rickeys bike, Rickey swapped over to the comp cnc package and made 254.

I just don't want you to make the same mistakes I made. Unfortunately, you already have the 1570 kit, and you already have the muzzy cams. If you hadn't already had them, I would have recommended a 1540 with a competition CNC head/cam, 47mm throttle bodies, carrillo rods. Even with that engine, you could have hung a turbo off the side (competition cnc does a slightly different package for turbo motors). I'd trust that exact motor to around 475 or MAYBE 500 hp (i'm not sure how strong those cranks are).

Regardless, I hope you enjoy the new motor. Don't let me fool you, the difference is night and day. It will be an amazing bike, and you'll need to invest in a tire company. But if you want to make the MOST power, get with competition cnc.

And, if i may offer some advice.. IF you want some help building the turbo motor, or advice, or tuning.. Call Walter Sprout with ECS performance. Tell him "Slow" from Oklahoma sent you. He's from Florida (i think?) and he's a genious when it comes to modern sportbikes, TURBOING, and tuning.

No problem, I do thank you for the advise and all the info you filled me in on. I did pick up that other motor for a grand with less than 3000 miles on it. so will look into building a turbo motor with it. Saw you bike you have for sale looks good. Let you all know what Adams can make with it.

Bike made 236hp spinning a 240 tire. Bike is for sale now major lower bask surgery doesn't like sport bikes.
Thanks everyone for all your advise on this build. have a set of Falicon rods and a Adams Low profile pan bunch of other stuff someone come get this its a blast on the street.
