spyder Posted November 1, 2009 Report Share Posted November 1, 2009 Im working on a '94 Banshee for a buddy of mine because he doesnt do motor work or tuning, and doesnt do this kinda thing at all. I do.. BUT Im not a banshee head. So Im comin to you guys. So heres the list, the way I picked it up. '94 Banshee Bored .030 over (brand new) T5 pipes Boyesen reeds (brand new) 270 mains Stock pilots Havent touched the mixture screws yet Uni air filter with extra breather holes cut in the box. The end result?? 1) Idles pretty smooth, but a little high. 2) Has NO throttle responce. The second I touch the throttle it either falls on its face, or has no powerband rev. Im at sea level, temp is running in the mid 50's lately. My question to you guys is.. If any of you are running a similar set up, what are your carb settings so I have a base point to start from. Pilot and main size, mixture screw settings from closed, spark plug and gap, intake set-up, and what reeds your running. Any info besides what I find in the search bar would be sweet. If someone wants to chime in and save me some time *high five* to you. I cant drive the damn thing because someone else play'd mechanic and pulled this thing apart (when it was re-built), now the clutch doesnt want to work correctly. I have great spring back pull but it acts like theres a plate or 2 missing in the basket. I can deal with that.. But I need it to rev and run correctly first before this thing goes out. The top end from what I can see is all done correctly and it fires right up, its just totally useless after that. Thanks in advance guys Pix of the fog machine Its actually .030 not .0030 lol dont ask..... Quote Link to comment Share on other sites More sharing options...
bansheesandrider Posted November 2, 2009 Report Share Posted November 2, 2009 I am guessing here but I would try 290-300 mains, 27.5 pilots, adjust the mixture screws for the highest idle speed and then adjust the idle speed screws for the proper idle speed. Does it still have the TORS system? If so unhook it by unplugging the wires on yhe black box on the left side of the frame under the gas tank, unplug the wires going to the tops of both carbs and also the thumb throttle on the bars. This will disable the system, if you want to remove it completely you will have to drill and tap the carbs for idle screws and get new carb tops and a throttle cable- it is available in a kit. Since it is a 94, it should not have the park brake rev limiter. Also, make sure you don't have any air leaks. Good luck. Quote Link to comment Share on other sites More sharing options...

pr0blumz Posted November 3, 2009 Report Share Posted November 3, 2009 X 2 on the tors. I agree. Quote Link to comment Share on other sites More sharing options...
Rodneya Posted November 3, 2009 Report Share Posted November 3, 2009 Look at the pictures, there are no TORS. You can see the carb cap in the second pic. Try going bigger on the main, and get the clutch together so you can do plug chops to check jetting. Quote Link to comment Share on other sites More sharing options...
RILS Posted November 3, 2009 Report Share Posted November 3, 2009 (edited) Im not sure what you have going on with the clutch but put some 27.5 pilots 320 mains and put the needle 3rd clip from the top.Set the airscrew 1.5 turns out. Get it to idle it should with this jetting ease into the throttle 1/4-1/2 way see how it acts on the needle should be pretty close. Then run it wide open in 4th gear for a few seconds dont let off pull in the clutch and hit the kill switch at the same time and see what your plugs look like. That should be pretty close to but u might be a little rich with that lid. Go ahead and check your pickup gap to your flywheel I use a business card or whatever thickish piece of paper I have on hand to set the gap .015-.020 is the number. That should get you up and going you will have to go into more detail on the clutch situation. You can get you some starting fluid and spray around the intakes and base gasket to check for airleaks.

Thats the kinda info I was lookin for.. Thanks man. Ill snag some jets and run it.. Also Ive delt with ALOT of carbs and havent seen any like these, on the outside of each carb theres a brass flat head screw with a brass lock nut on it. This is the idle screw on these correct? Theres no spring behind it, just a rounded off edge.. For some ungodly reason this thing was converted to twist throttle too..

AKheathen Posted November 6, 2009 Report Share Posted November 6, 2009 yah, those are the idle screws for the3 stock carbs when you remove the tors caps. and, that's not the right way to to a plug chop. you get it up to operating temp by ridding around, then stop at a strait stretch and put in new plugs right away. start it, and instantly run it through all the gears, or as many as you can wot, (10seconds minimum) and pull the clutch and kill it and roll/brake to a stop without letting the engine tun over. change the plugs again and go read those ones. the point is to get the reading by only runnung on the mains. if you do a search, you can find the writups on how to do a plug chop, and read.

Toomey Banshee Posted November 7, 2009 Report Share Posted November 7, 2009 With the box with no lid on our 99 and T-5's we ran 330 mains, 30 pilots, dont remember clip postion. Check and make sure the parking brake is disconnected. Also check that the tube connecting the 2 carbs is connected, free of blockage and no holes.

Ill check that connecting hose out and se if theres any pin holes in it.. But this quad is definitely acting like its starving for fuel. Ill have to play with the jetting with the numbers you guys are throwin at me to see what will work on this turd. Round about how many turns from closed are those idle screws usually set at? Just so I have an even base point to start with.. Thanks guys Quote Link to comment Share on other sites More sharing options...

dajogejr Posted November 7, 2009 Report Share Posted November 7, 2009 With a lid on and hole drilled in it...I think you're closer to your jetting than people are giving you credit for. We run 270 to 290 here with a stock air box, no lid. Make sure ALL of the TORS components are removed and disconnected. Check all electrical first. It has no throttle response...he's not on the main yet. I think you're going to find one of two things, electrical or an air leak. Quote Link to comment Share on other sites More sharing options...
rubberneck Posted November 7, 2009 Report Share Posted November 7, 2009 i agree, with the uni filter and vent holes, at sea level i run 290 mains and 25 pilots. if you go to pods then you need to step up to 320-330. start with the needle in the middle and airscrews 1.5 turns out. Also make sure the carbs are synched properly both at idle and with the throttle cracked open. Make sure there are no air leaks Quote Link to comment Share on other sites More sharing options...

Thanks guys This was when we had the pro design plate and a single foam filter. Stock bore. The bike was jetted spot on then. Ran hard as hell. I agree with Dajogejr about the electrical issue though. When I first put the Toomeys on it acted very similar to what you're describing and it was the TORS. Acted up again a short time after that, again acting similar, we unplugged the parking brake and it was fixed. Quote Link to comment Share on other sites More sharing options...
