does anyone have any ideas on how to run duals on an brute?

only seen it a few times, with the way our gas tanks are it's very close... custom built from the ground up kinda thing.

Yup, either too close to the tamk or in the tire's way on the right side. Theother way is both on the left side like a over/under shotgun kinda thing. Works good though.

I know that LTE makes duals for the Prairie. Over/ under on the left, just like NM states. I am not sure if they have an application for the BF750.

AM, check out this twobrothers setup. Homemade pipes, and it might have a problem rubbing, but sitting there its looking not too bad.

Looks, and sounds, good. I guess you certainly could make up your own pipes. Pipe bender and mad skills!

ok a think im gone do it i have the welding skill seeing thats what i am. but i went to measuring on it and if i put 28s it going to be super damn close but i guess if i pull it off it will be bad ass.

i thought about puting them side bye side but it would be really close iand over an under would be hard to because of the spring im prolly gone raise the top pipe a inch and a half and try to fit the other in under it on top of the spring. but i also seen a guy withone on right and left it was on you tube and it sounded like a damn harley just wicked as hell but i will let yal no if i pull it off with pics and vids.

Can't wait to see it! Make sure that you get lots of pictures.

wheel spacers? to keep it from rubbing? when running two pipes meant for one engine. does the lack of back pressure affect the engine?

Oh yeah...rejetting is necessary and if you let it out easier, you have to let it in easier for balance...more jetting again.. and if the back pressure falls below a certain amount...like .002 oz, scavenging falls off enough to possibility make such a flat spot between idle and transition, you might need an accelerator pump to stop the popping. Might be able to richen the pilot or slow system to overcome that though. Sure would smell rich though I think.
