paradisej Posted January 17, 2013 Report Share Posted January 17, 2013 I have a 87 shee that is stock bore, with a dune port job, stock carbs, and Bills pipes. Is it worth changing to a single carb set up? If so why, and what are the benefits? Thanks Jason Quote Link to comment Share on other sites More sharing options...
04_blu_shee Posted January 17, 2013 Report Share Posted January 17, 2013 No top end power from a single...Banshees love to eat, give it seperat feeders and let er rip Quote Link to comment Share on other sites More sharing options...
Rustynail Posted January 17, 2013 Report Share Posted January 17, 2013 Benefits, easy to tune, no synching only I jet to change for summer/winter riding. If your just doing trails and stuff they work ok, but not worth the high dollar price tag. Quote Link to comment Share on other sites More sharing options...
BigRed350x Posted January 17, 2013 Report Share Posted January 17, 2013 No top end power from a single?? Please explain in great detail which single carb setups you have ridden in which there was no top end. What kind of carbs, jetting, manifold? I run a single carb on my motocross bike and there is nothing wrong with top end performance. Paradisej, to answer your question, no, its not really worth it for you to switch to a single carb unless you are having issues with your dual carbs. Smaller dual carbs work great for mid range power, and there isn't much of a power gain down there when switching. The main benefit is what Rusty said, they are easier to tune. Dont let anybody tell you a single carb banshee doesnt run good, though. a single carb banshee doenst run good. Quote Link to comment Share on other sites More sharing options...
lms1977 Posted January 17, 2013 Report Share Posted January 17, 2013 I had one but now that I sold all my old parts to my buddy and he put the stock carbs back on it runs better everywhere with twin carbs Quote Link to comment Share on other sites More sharing options...
MarineNYC Posted January 17, 2013 Report Share Posted January 17, 2013 a single carb banshee doenst run good. X2. I ran the trinity system for quite some time. Then switched to dual 35 pwk. And wow. Can't believe I was missing all that fun for that long. Quote Link to comment Share on other sites More sharing options...
paradisej Posted January 18, 2013 Author Report Share Posted January 18, 2013 Thanks for all the great advice! I think I will invest in some better carbs and reeds. Thanks again Jason Quote Link to comment Share on other sites More sharing options...

trickedcarbine Posted January 18, 2013 Report Share Posted January 18, 2013 There are many 2 cylinder 2 strokes out there that run great on 2/1 manifolds. The only reason most people think banshees can't run good on them is because the only readily available bolt on manifolds are fucking garbage. Trinity = restrictive junk. Although their concept was a good idea. The new chariot is better, but still not much better. Graydon had their Proline manifold but even that was pretty poor. If you are serious about the swap, do it with an old 440 exciter manifold. Takes a little modding but it's like a single plane manifold for your big block. It works, but it requires a 39mm carb or bigger. My buddy did one on his clean up only 4mil build and it pulls plenty friggin hard for a stock cyl 4mil that hasn't really been ported Quote Link to comment Share on other sites More sharing options...
BigRed350x Posted January 19, 2013 Report Share Posted January 19, 2013 Why in the hell would you build a 4mil without getting a good port-job? Fail. Quote Link to comment Share on other sites More sharing options...
Larry's Shee Posted January 19, 2013 Report Share Posted January 19, 2013 i actually have one of these intake manifolds with boot for sale. How much for your fuel injection? Quote Link to comment Share on other sites More sharing options...

spurdy Posted January 19, 2013 Report Share Posted January 19, 2013 Let's see a picture of that intake Zilla. I am putting a single on Ethan's motor for hime to start with. Running a 33 PWK behind a set of PT mids on a little ported 350. Not sure how long he'll ride it like this before he'll want to step up to a set of duals with some inframe drag pipes but I think this will be a fun little torque motor for him for awhile.

trickedcarbine Posted January 19, 2013 Report Share Posted January 19, 2013 Why in the hell would you build a 4mil without getting a good port-job? Fail. Simple, he was shy on time and cash. Plus he was afraid to have some one fuck it up with out doing more research. So he just adjusted the heights and did a clean up. Quote Link to comment Share on other sites More sharing options...
spurdy Posted January 20, 2013 Report Share Posted January 20, 2013 Zilla, I've got a Trinity one and I don't see much difference in the intake tract on that one over the Trinity. How are they so different? SP Quote Link to comment Share on other sites More sharing options...
