New banshee, new mods, what jet?

[blaster2006]

heya, im about to buy a banshee from a guy here. and he said if i buy it for the stock price, he will give me brand new set of toomey T5s. and maybe K&N filters. now, ive got a couple of questions.

 

lets say i got only the pipes, i would then remove the air box lid anyway, so thats increasing the air flow, and then i got the pipes installed, what main jet should i jump up to? and should i change any other jets?

 

 

Now, 1 thing i should let you people know, i currently have a yamaha blaster, when i had it stock, i did a plug check, and it was running rich on the stock everything and stock 230 main jet ofcourse, it was running pretty rich, all black the plug was, this is porbably because im at sea level, and its somewhat hot here, its only about 65 degrees F at winter... and way hotter in summer. so when i got my mods for the blaster, which is pipe, reeds, and i put some holes in the air box ( not removed), i moved from the stock 230, to a 250 main jet, my plug checks golden now, it runs decent, but im having some problems at 1/4 throttle, when i rev it from idle - 1/4 throttle, i feel a werid noise... cant explain, and when it reaches half way to full, it sounds perfect... now, im not sure what i have to change but anyway.

 

So im assuming the stock shee is also going to have black plugs already, so when i put the pipes, and remove the airbox lid, what jet should i use? and what other air screw or whatever pilot etc jets must i change to remove this low end "weird power" problem that i have on my blaster?

 

Oh and last question, the stock main jet of a shee is a 230 or 240?

You should be around 300 on the main jet, clip in the middle on the needle, and 27.5 on the pilot and around 11/2 turns ont the air screw.

 

Those blasters make alot of piston noises, you dont have a water jacket around the cylinder to dampen any noises but i don't know if this is what you are hearing or feeling.

stock jetting is around 190-220, I forgot the manufacturer will change it depending on where it's sold... IDK if stock brand new price is worth T-5's and k&n pods, If he charges you 3000 for it I would keep looking because the deals are out there you may just have to look. As far as mods like I said try 290 and do a plug chop that will tell you to go richer or leaner, you don't need to change you pilot for only those couple mods. If you look at my sig. I run all those at sea level and I live in AK so my jetting will be richer than yours due to the coldness and I'm starting out with 320 mains needle on third clip and the stock pilot jet I may have to go to 27.5 pilot , but most likely only in the winter when it's like 20 degrees
