i have a newb question

[ballsdeep]

i'm relatively new to the banshee scene. im currently deployed to afghanistan but when i went home for R&R i was lucky enough to find a 2003 banshee in amazing shape for $2500. the bike is a beast but like anyone i wanna make it faster. i see people talking about boring out 4mm and so on. what exactly does that mean, how is it done?

Boring a motor is often more detrimental than leaving it the way it is. Without getting too technical, the larger the bore, the smaller the cylinder transfer area. Not a considerable loss in performance, but it is worth noting and definitely not worth bragging about. If anything I would stay away from a motor like this because if you do hurt a piston...chances are you can't bore it to fix it.

 

A 4mm/7mm/10mm/etc is referring to the overall travel that the piston moves up and down. By increasing the stroke of a motor you can greatly increase the performance of the motor.

thanks! i feel smarter already

wats done to it now ?

if its stock, some pipes, timing plate, cool head with smaller dome and air cleaner setup will give noticeable gains. if thats already done, porting will wake her up.

 

theres always something to do to a banshee to make it faster.

as far as i know its only upgrade is the the exhauste.. im a full CPI exhaust. alot of people are telling me to switch toomey, but i like the way it looks and sounds already plus im not trying to be like everybody else!

 

what is porting?

[06specialedition]

If you have all your major bolt ons like, pipes, reeds, cool head, timing plate..etc. You can get it ported and will make a huge differance. I had Brandon @ Wildcard Racing do mine and he is a site sponsor on here

Porting is when you change the size, duration, shape and angles in your intake, transfer and exhaust ports in your cylinder.

This way you can modify the power output in your motor.

Porting is something that should always be done by professional builder.

...something like that.

You dont bore out a 2 stroke to make it faster. You only bore out usually to repair a harmed cylinder.

 

I hear that all the time from ignorant 4 stroke people.

 

CPI's are good pipes. Very high in demand and can offer some good money if you chose to get rid of them. They arent really best for non ported engines. However, they will work fine. And if you never had much time on a bike with anything else, you probably wont notice the difference. The pipes(along with other factors but pipes are very important) determine how the powerband acts.

 

CPI's are more of an inframe drag pipe. They will rev higher than toomey's but come on(by come on i mean when the powerband hits) a little later in the rpm range.

 

Before you start ordering all sorts of goodies, just take time to get acquired with your new machine. Enjoy it, make sure all your fluids are ok. Check for loose screws etc. You can learn a lot from these forums but anything you have questions about feel free to ask. Sometimes, people might unwillingly give you false info. But that's on any forum. Luckly, one of us will steer you right.

 

Now on to porting. It's one of the best mods for your money you can do. There's many companies who do it. Some people including myself chose to swing from a builders nuts due to satisfaction of their work etc. Research and go from there. Again, enjoy the bike as is before tearing it down to get the cylinders ported.

 

Welcome to HQ and thank you VERY much for serving our country!
