streetshee Posted November 15, 2008 Report Share Posted November 15, 2008 hello lads,ive started my reverse cylinder ypvs conversion on my street legal shee,heres a few pics,welds are rough,i havent ground them yet. im just not sure of the angle of the carbs though? ive got 36mm mikuni tm's and think they can be tilted quite a lot before the floats play havoc cant they? or should i turn the intakes upside down? will that mess up the fuel/air to the boost port? http://s355.photobucket.com/albums/r469/scoobyhunter/ Quote Link to comment Share on other sites More sharing options...

Keyser Soze Posted November 15, 2008 Report Share Posted November 15, 2008 It will work speedy. There is a video on youtube of pretty much the exact same thing. Quote Link to comment Share on other sites More sharing options...

NYUK Posted November 16, 2008 Report Share Posted November 16, 2008 it`s been done. no kinda gain. dynoedge did it 10 years ago. banshee cylinders.made less hp than a normally placed set of cylinders. more work, no gain. just to show it could be done.neat looking set up with the pipes straight out the back.

Keyser Soze Posted November 16, 2008 Report Share Posted November 16, 2008 Wouldnt it be taking a lot more air in? Quote Link to comment Share on other sites More sharing options...
Sheesbest Posted November 16, 2008 Report Share Posted November 16, 2008 because i can m8! Next one mount the jugs side ways and then ride it like a Hog, :biggrin: Quote Link to comment Share on other sites More sharing options...
dajogejr Posted November 16, 2008 Report Share Posted November 16, 2008 Wouldnt it be taking a lot more air in? At the speeds you get on a banshee (70ish to 80) no...it is not enough to make a difference. If this was on a road race bike that saw 120 to 150MPH alot, yeah, it would be worth a couple HP...maybe. As said, John @ DynoEdge here in MI did this a long time ago. If you want it for the "cool, different" factor...go for it. But that's all it's gonna be!

streetshee Posted November 16, 2008 Author Report Share Posted November 16, 2008 yes its just for the "what the fcuk,your engine is backwards m8!" and to be different,ive got an rz gearbox and right side case with oil pump so i dont have to carry oil with me.(cos shees street legal).next on list is zeeltronic ignition combined ypvs in one box.i spent the weekend on my lath(its only small) making a lock up clutch cover,looks sweet,just got to get some plexi glass or something for the cover.

4stroker Posted November 18, 2008 Report Share Posted November 18, 2008 thats awesome man, great job! i like the fact that your out in the shed making your own parts and trying different things yourself! makes for alot more interesting reading than all the bloody "what jets should i run" threads on here! gonna build the pipes yourself? shouldnt be too hard with such a straight run back through the bike! might be a tight squeeze for large chambers though!

streetshee Posted November 18, 2008 Author Report Share Posted November 18, 2008 thankyou,yes im going to make the pipes myself,ive downloaded a cone making software but im not sure yet what pipes to make,i might copy my 916 pipes? ill have to have a doubled back end pipe/s to get it all in,maybe i can loose some length by making the header pipes an 's' shape,then maybe i can get the pipe to sit straight backwards with the tailpipe/s pointing straight into the teeth of everyone behind!! lol.

dirtfreak Posted November 18, 2008 Report Share Posted November 18, 2008 cool set up,with all the fabrication ahead with exhaust etc i would have went with a bigger cc engine,but it should work well. Quote Link to comment Share on other sites More sharing options...
