ness Posted July 29, 2004 Report Share Posted July 29, 2004 My riding season will be over in a few months, so over the winter I'm wanting to do something to the Banshee to get a little more power. Because of trail restrictions where I live I need to keep away from aftermarket pipes. My Banshee engine is stock with the exception of a Noss head with 21cc domes. I was throughly impressed with the increased performance from the Noss head, and am looking for a modification that will offer a similar power increase without sacraficing gobs of reliability. Any sujestions?...and please remember I will need to keep the stock exhaust setup, Thanks. Quote Link to comment Share on other sites More sharing options...
racer Posted July 29, 2004 Report Share Posted July 29, 2004 i know you said you need to keep the stock exhaust setup but what about some PT mids? They look almost identical to stock, especially if youre just some two-bit park ranger. that'd give you tons more power. Just have them PCed or painted a high temp black and call it good.

ness Posted July 29, 2004 Author Report Share Posted July 29, 2004 therail, couple questions. Who makes PT mids? Would they be significantly louder than stock? Do they have spark arrester, or hush kits available? Thanks. Quote Link to comment Share on other sites More sharing options...
Hockey390 Posted July 29, 2004 Report Share Posted July 29, 2004 lighten the flywheel, remove the airbox, add a K&N filter... It all depends on how much you want to spend. Your mods are going to be restricted if you use the stock exhaust, but if you MUST keep it then you have no other choice. Out of curiousity what are the restrictions and where are you located? I know that here in Michigan it just needs to meet the forestry guidelines, which are spark arrestors.. Post a price you want to go with, then people can suggest what is best. Also what type of riding are you doing? Low speed? Mid range? Racing? That will all determine what mods. Quote Link to comment Share on other sites More sharing options...
racer Posted July 29, 2004 Report Share Posted July 29, 2004 as for who makes them i dunno . but i do know that duncan racing is a distributor for them. they do have silencers, but im not sure about a hush kit. i also dont know for sure how much louder they will be than stock but i sure it will be. someone who has a set get us informed here.

ness Posted July 29, 2004 Author Report Share Posted July 29, 2004 Hockey390, I live in Minnesota. I used to have private land to ride on, but farm was just recently sold. If I would have had 4.5 Mil I would have bought it. So now I mostly ride in State Forests where there are noise restrictions of I belive 98db, and forestry approved spark arrest. I have never even seen an enforcement officer out at the trails, but am paranoid that after driving 100 or more miles to the trail I'll get checked and will have to drive home with my dick in my hand. Most of the trails are through the woods, and it is a rare ocasion to even get into sixth gear. I do a lot of on the gas hard then off then on hard again. Kind of point and shoot, bring it back down then hammer it again so I don't need top end. I was prepared to spend around 5-6 hundred.

Wassup350 Posted July 29, 2004 Report Share Posted July 29, 2004 (edited) I would invest in some FMF Q silencers and some gnarlies or fatties. I think those pipes would suit you well since you ride trails. The gnarlies will give you more bottom end power and have similar or more then stock top end from what i understand. https://www.fmfracing.com/products/catalog....?CategoryID=101 Thats the gnarlies https://www.fmfracing.com/products/catalog....?CategoryID=113 And those are the Q silencers which are said to be at 96 DB which is us forest legal or something like that. https://www.fmfracing.com/products/catalog....0&ItemID=020145 Fatties http://www.duncanracing.com/atvproducts/index.phtml?id=1 PTR mids You may also be able to fit the stock silencers on aftermarket pipes, you probably wont see as big of a combination as a silencer/pipe package, but you will still see power increases.

sredish Posted July 29, 2004 Report Share Posted July 29, 2004 (edited) OK, you want stock pipes, that's fine. The only other thing that I can think of that will get you decent amount of additional power is: Pro Design ProFlow air filter plate with Uni or k&n filter. This is more a necessity than a want, due to the crappy stock setup. Trinity 33mm Single Carb. Will do wonders for your low to mid power and enhance your top end too. This is the one big thing you can do for power and keep your stock pipes. VForce Reeds, these will help the flow of air through your new carb (see above) and enhance overall power. After all this, you still need some power from your stock piped shee, get a real mild port & polish done. Not too much, because your stock pipes can't breathe enough for a lot of porting. Later.

mrmatt Posted July 29, 2004 Report Share Posted July 29, 2004 You can use stock silencers with the PT mids. But, like Wassup said, you may not get all of the potential out of the pipe. Since you don't want to change the exhaust, you have a couple of options in your price range. 1. Porting 2. Reeds + Advance Timing + Aftermarket Air filter Quote Link to comment Share on other sites More sharing options...
frocashmoney24 Posted July 29, 2004 Report Share Posted July 29, 2004 i def say go wtih a filter, +4 advanced timeing, and some reeds, that'll get you up to about..250 bucks-300 depending what you buy and where, then i say you drop the other 300 on a set of used toomeys, and get te hush kit, which makes the pipes as queit as possible, and puts spark arresters in, there legal in everysingle forest ive ever heard about Quote Link to comment Share on other sites More sharing options...
ness Posted July 29, 2004 Author Report Share Posted July 29, 2004 Thanks everyone. I'm going to look into the 33mm single, and an air filter. I looked on Trinity's web site and they briefly describe the performance of this set up. Sounds like what I'm looking for. I just have to do some more research on it because I don't understand how the performance is gained from the stock two carb set up. Quote Link to comment Share on other sites More sharing options...
sredish Posted July 29, 2004 Report Share Posted July 29, 2004 I just have to do some more research on it because I don't understand how the performance is gained from the stock two carb set up. more and more efficient airflow, especially at lower rpms. the cylinders do not fire at the same time, one fires then the other, on a 180 degree cycle. with a dual carb setup, the air rushes in, then stops, then rushes in, then stops, very very quickly, from one cylinder/carb to the other. with a single carb, there's a constant flow of air coming through the carb (hence the name, constant velocity kit) and this provides a more efficient flow to the cylinders especially at lower rpms, therefore boosting power. also, the larger bore increases overall flow. that's the jist of it anyways. there's loads of posts on the single carb setup, search some here.

ness Posted July 29, 2004 Author Report Share Posted July 29, 2004 sredish, ok that helps I think I have a better understanding now. The advantage is better flow, and more fuel. So the trinity is a constant velocity carb, what is the stock carb system called? Quote Link to comment Share on other sites More sharing options...

So the trinity is a constant velocity carb, what is the stock carb system called? actually, the carb isn't a "constant velocity" carb, but the way the intake works with the carb, it receives a "constant velocity" of air/fuel so they've named it the C.V. kit. I call the stock carb system, "shitty". Quote Link to comment Share on other sites More sharing options...
Wassup350 Posted July 29, 2004 Report Share Posted July 29, 2004 I call the stock carb system, "shitty". Right on man!!!! I will never go back to the stock carbs, anything is better than those hunks of shit. I've had so much trouble with my throttle sticking on those things. Single carb is way easier to tune also, the air box adaptor is kind of a pain in the ass though Quote Link to comment Share on other sites More sharing options...
