Ok im prolly going to get a 240 kit with the moneys i get from x-mas. i got a few questions... 1) when i have it ported i want to have it ported to the max right? 2)my bros friend has ported tons of bikes and quads but i think i want to take it to a machine shop would there be any difference in hp from the kid to the machine shop? 3)do i have to get a bigger carb for a significant hp difference? i was readin a magazine where they did a test on hi-per carbs and they only added like 2-3 hp for 2-400$. and 5) can i use my regular pipe and do i have to rejet?
thanks guys
chris

yea, you need a bigger carb, intake, if you still have the stock exhaust youll need a new pipe/silencer, probly a new clutch (after you smoke the stock one with the 240's hp) a new air filter, dude if youre quad is all stock, you better have some serious cash. i think CT racing has a 240 kit that comes with all that stuff for like $1000.00, otherwise look around on ebay for used stuff. might save you some cash.

edit: why do i need a bigger carb? in the magazine they tested the carbs on a 440ex with pipes and it only produced a few more hp over the stock carb when it was on the 440ex..i know i need porting and polishing but is a carb that big of a deal?

remember that your engine is a big pump. the more air/fuel it takes in, the more power it puts out. Grab a 34mm carb..big difference. You can use a stock, but your only wasting power that you have already paid for in the 240 kit. BTW, get a strong clutch...my stock lasted one day with the 240

Get it ported, you won't notice a big difference with the 240 without porting.

Guys - It's unclear to me what you mean whan you say you're buying Vito's 240 kit, and porting and polishing...

Do you mean you're paying $249 for the kit
$??? for "Installation"
$??? for "Porting"

I guess, depending on what installation runs you, you may be getting a decent price.

I just want to make you aware that the ports in the new Big Bore sleeve are already set at what the 240 kit needs to run strong (In essence, the sleeve is Pre-Ported. After the sleeve is installed, the installer should match the ports to those in the sleeve to do the kit properly, and this fee should be included in the installation fee. If additional port timing is requested by you, then it'll cost$$$, but unlike other kits, the Vito's kit, for all intensive purposes, comes Pre-Ported - all ya gotta do is match'em up!

if i were you i wouldnt buy a vito's. send your engine in to Trenga Racing. you still need to have a carb,pipe/silencer... and all that but they will do a great job. they have been dealing with blasters for 9 years and they do all the machining thats needed to get the power you want.

you pay $249 and all you get is the kit from vito's. Then you pay another $160 and they will install it and port it. Plus shipping charges apply to both costs.

When I said get it ported, I meant if you can ONLY get a 240 kit, OR porting, get the porting, you will get more of a power increase with porting alone, than a 240cc bore alone.

You need to visit trinityracing.com or ctracing.com. They both have really nice bore kits. Their kits include the carb,pipe,240 and instalation. I would check it out. Also they make the best pipe available and their kits give the maximum amount of hp a 240 kit can give.
