Hi,

I'm having problems with a friends Banshee. My 250R is piped, ported, pro-design head, 38 mm PJ carb with 185 main jet, boyesen rad valve, k&n air filter and I'm unable to reel him in.

I don't have problems with stock Banshees, but his has FMF fatty pipes, trinity head, v-force rad valves, boost bottle, dial-a-jet and boost bottle.

I'm presently running a stock head gasket and just premium pump gas. I think I'll switch to a CR head gasket and run octane boost. Any other suggestions would be appreciated.

Thanks.

Ken

 

I've beat banshees with more than that with my mods....

 

how bad is he beating you? what kind of pipe do u have?

your mods seem to be more than enough to beat him. banshees dont seem to really come alive untill you start seeing some internaly machine work. after that watch out!!! ive raced plenty of misc bolt on banshees and never had a problem beating them and suprisingly most of my wins were because of top end power.

 

your cylinders dont have a good port job obviously. You should walk away and embarass this guy.

Are you running in the sand or on the street? if sand, what tires

what pipe? a smaller carb might help your little motor out tooo

 

250Rs were meant mostly for mx but not so much drag racing due to lowend power. but a banshee was meant for just the opposite,Dragracing and not so much mx, but mine does do pretty good on the mx track, funny isnt it. [img]i/expressions/face-icon-small-smile.gif[/img]

 

my LT50 would beat all your quads, and its stock

 

You must not keep up with drag racing these days huh? Last memorial hondas were running upwards of 76 mph, all under 500cc's. It took the 540cc cheetahs to be able to beat these honda's. So much for slow honda's huh?

Your LT aint got sh*t! lmao jk

i got an lt80 with your name all over it pal

 

Hi,

Thanks for the feedback guys. I'm running a Bill's pipe with a Paul Turner Fatboy silencer. I know it's not a real popular pipe, but I always kinda thought a pipe is a pipe. Didn't think there would be a noticable difference going to a different one.

Not sure if any of you are farmers, but we typically race in bean or corn stubble or sometimes on the road (pavement). The differences in horsepower start to become apparent in 5th and 6th gear. I most often holeshot him as I have better tires and the Banshee tends to spin (on the dirt anyway), but he runs me down in the long run.

Someone mentioned running a smaller carb. I have the original 34 mm I could use. Wouldn't the 38 be better however for top-end power? What kind of gains could be realized through running an ATC 250R or CR head gasket?

Like I said earlier, I usually have no problems with stock to mildly modified Banshees. I ran down my first Polaris Predator on the weekend with no problems as well.

Thanks again for your help.

Ken

 

a pipe is what makes a motor run.

 

Hi,

Two other points for discussion.

I've always ran 20:1 in my 250. Could I get some power gains by running a less rich mixture? Say 32:1? Also, I was running a 162 main jet until I went to the bigger carb. I then went to a 165. It ran fine on this for about a year and a half and then one day seized while cruising down the road at 1/2 throttle in 6th gear. After the rebuild, I went rich to be safe (192), then down to a 185 which it seems to burn fine. But this is a heck of a lot bigger than the 165 I used to run. Perhaps I'm still too rich on the main jet?

Again, any help would be appreciated.
