help in tuning

[johny55]

Hello. I`m a new here on the forum. I have a serial Banshee from 2001 and I think about tuning-engine. I`m going to buy: Exhaust FMF Fatty, V-Force 3, a set Dynojet 280,CDI Dynatek, Boost Bottle, filter TwinAir. I want buy Cool Head Pro Desing. And I have any question for you. Will be good head with 20cc Domes to a serial cylinder with pistons and carburetors? Because I don`t want that pistons knock against head decline attaintment performance Banshee, but I want that compression will be bigger. Whether this head give some power? Whether worth change head, if I think about growth power? Maybe leave simply orginal head?

welcome.... first off, save yourself some money and do not buy the boost bottle or jet kit. the boost bottles do not do anything for performance, and are highly known for tearing the rubber intakes and causing a bad airleak that could melt the pistons. as for the jets, simply buy jets on individual sizes, instead of paying 10x as much for a kit. as far as picking the correct size, we will need to know your elevation and ridding temperatures and can get you in a close range. now for the coolhead, it will add some good power. the dome size will also depend on what your elevation is and what octane fuel you are running. i can tell you that 21cc domes will be safe anywhere, but, you may be able to run even smaller and gain more power, depending on your circumstances.

I would NOT use a pro design cool head, you have to change out your head studs to use these and there are alot of good heads out there that you do not need to do this. You can break one of the studs off, or the threads can come out of the cylinder then you need heli coils. And i don't like the coolant flow in the pro design cool head, it allows the coolant to just shoot over the top of the domes instead of making the coolant go down into the cylinders to cool them.

My head hurts!!!

 

What octane of gas are you wanting to run?

What is your elevation?

What type of riding will you be doing?

Why do you want the CDI? Is the stock one working ok?

Is the bike all stock?

Do you have the crazy looking boxes (tors) on top of the carbs?

For the Boost bottle and the price of the jet kits. You should be close to having a timing plate and impeller.

Ok.So Boost Bottle don`t buy better because something maybe will damage in ATV. With this CDI I think change on sports oneself for example Dynatek or Procom. But must I to arrange something after instal CDI? But if I put on expiration FMF Fatty, either flow nozzles, so and CDI delivered the goods. Banshee I will be go a petrol 95 octanes, mainly en course and at intervals en public cross track. I spoke with mechanic and he told me that also good I can aplair a serial head about 2mm and also to wind up power. Is it true?Do I have exlude torso over carburettors? Desirable that you will write me how I can to install in Banshee that wind up power, because I`m not from USA but from Poland and I will must to order anything.

I tried google translator and heres what I got:

But I have to arrange something after the installation of CDI? But if I put on the end of FMF Fatty or flow nozzles, so the CDI delivered the goods. Banshee will go petrol 95 octanes, mostly en course, in the intervals of public en track cross. I talked to the mechanic and told me that I also have a clear head aplair series of 2mm, and the elimination of power. Is this true? Do I have to exclude the body of the carburetors? Preferable that you write me how do I install the Banshee, that the termination of power, because "I'm not from USA but from Poland and I will be nothing on the agenda

 

Maybe if you can use the google translator from Polish to English we will able to understand you.

Im lost as a virgin on prom night!

[AKheathen]

well, i believe that is the result of google translator, actually. ok, from what i got out of it....

1 boost bodles are bad, ok

2 the dynatek ignition is a verry nice peice, if you need it, because, yes, you can change different timing curves by flipping the switches, and it increases spark energy on your stock coil for better firing and starting.

3 the dyna will just plug in where the stock cdi belongs and work perfect, but you have the option to connect more to it.

4 the cdi will NOT correct the jetting for the pipes. you still have increase the jet size to match. same thing if you change or remove the airbox.

5 you can mill the head for higher compression, but you can only go as far as .030" before you also have to re-cut the chambers, or else the piston will hit. you can also buy a "coolhead" "power head" "hemi head" which you can buy domes of the size you want. the domes are the chambers. i say you want 20 or 21 cubic centemeters (cc) for 95 octane, but your elevation can change that size.

6 i believe you are talking about the tors delete. it is a good thing to do. they do fail and shut off your spark. the big peices on the top of the carbeurators get in the way and put extra weight on the rubber intakes, also causing them to crack. it is simple to do if you have patience and do not rush the repair.

 

and, finally. tell us your riding temperature and elevation and we will tell what size fuel jets to install in your carbeurators.
