locogato11283 Posted January 5, 2011 Report Posted January 5, 2011 Just curious as to what kind of gearing everyone runs on their typical rising surface.. So, let's try this format.. Use this gearing chart.. http://home.earthlink.net/~gellett/banshee.htm Motor: 18mm DM 688cc Max RPM: 10,000 Gearing: 19/41 Primaries: Stock Actual tire size: 20" (Most tires are not as tall as they say on the side) Terrain: Dirt Launch gear: 2nd *Miles Per Hour 1st: 39 *Miles Per Hour 2nd: 53 *Miles Per Hour 3rd: 64 *Miles Per Hour 4th: 76 *Miles Per Hour 5th: 92 *Miles Per Hour 6th: 109 Quote
camatv Posted January 5, 2011 Report Posted January 5, 2011 thats pretty cool 10500 15/40 26inch tire sand launch in 1st 43 1st 58 2nd 70 3rd 84 4th 101 5th no 6th seems right as i tried to gear to hit 80mph in 4th on gps and my rpm was showing avg shift rpm at 10,500 to 11000 overrev and i almost never get the bike into 5th Quote
camatv Posted January 5, 2011 Report Posted January 5, 2011 hmm how about this. 14 41 22inch tire launch in 2nd sometimes 1st 350cc 33 1st 45 2nd 54 3rd 65 4th 78 5th 93 6th Quote
camatv Posted January 5, 2011 Report Posted January 5, 2011 the so called "trail gearing" and why it SUCKS 13/40 20" tire dirt.. 24 1st 32 2nd 39 3rd 47 4th 56 5th 67 6th Quote
bigboybanshee Posted January 5, 2011 Report Posted January 5, 2011 10mm DM Stock ratio primaries 16/41, 1-5 transmission, leave in second Tire height: 22" 300' dirt 2 - 49.13 3 - 59.35 4 - 71.23 5 - 85.2 The calculator seems to be pretty close, I have several timeslips in the 80-82mph range. Quote
BANSHEE HP Posted January 5, 2011 Report Posted January 5, 2011 421 cub 1-5 22'' tire 300 sand 10,900 rpm 15/46 1 - 32 2 - 44 3 - 54 4 - 64 5 - 77 Quote
dajogejr Posted January 14, 2011 Report Posted January 14, 2011 I'd say it's close. Weight has to do with MPH as well... I'm 250..I go through the traps at 72 to 76MPH. I put a 175lb guy on it and it's 76 to 80MPH, same gearing. 10 mil cub 10,500 RPM (Best guess) 22 inch 14 paddle tire 16/47 or 46 gearing 2nd 45.01 3rd 54.37 4th 65.24 5th 78.04 Quote
J-Madd Posted January 14, 2011 Report Posted January 14, 2011 10mm Cub Stock ratio primaries 16/45, 1-5 transmission, leave in second Tire height: 24" 300' dirt Max RPM 9600 (per Dyno this was the peak hp RPM) 2 - 46.86 3 - 56.6 4 - 67.92 5 - 81.25 Same as above, run with 22.2" tires sometimes: 2- 45.29 3- 54.71 4- 65.65 5- 78.53 THis as also about right. The motor will overrev a little with these tires and it will sometimes hit 80 mph with this gearing. I may post some 421 Cubs and a couple of bigger motor examples if I get a chance. Quote
camatv Posted January 15, 2011 Report Posted January 15, 2011 i dont know why but that black bike looks badd ass to me!! Quote
Pasi S. Posted January 22, 2011 Report Posted January 22, 2011 This is mine. It´s not a drag Banshee but I´ll be doing some 1/8 on asphalt and 500ft. on dirt. This is what I use with my 22" RazrII winter tires with 250 ice studs on each rear tire. With stock 14-41 gearing there was not enough power in my motor to turn these tires. -Pasi S. Quote
tiffnaub Posted January 25, 2011 Report Posted January 25, 2011 I HAVE A 421 CUB WITH 22/11/8 HAULERS 11 PADDLES DRAG PORTED LOCK OUT CLUTCH GETTING 85 HP WITH 14/40 ON MY GEARING IM NOT GETTING A GOOD LAUNCH WHAT GEARING WILL HELP ME OUT, BUT MY TOP END SPEED IS GOOD Quote
RadarRacing Posted February 3, 2011 Report Posted February 3, 2011 Your gearing is about right for your 11 paddles. IMO you need more paddle than 11 or have too long of a swingarm. Quote
RadarRacing Posted February 3, 2011 Report Posted February 3, 2011 Tiffnaub, your gearing is about right for your 11 paddles or you could run higher gearing. IMO you need more paddle than 11 or have too long of a swingarm. Also if you are running 85mph in 300' with a 421 I'd seriously question the mph or kudos cuz that's darn fast.I'm guessing that's 400 or so. Quote
camatv Posted February 4, 2011 Report Posted February 4, 2011 85 is flying if the 60 was good. track frame !! Quote
