Author Message   S_one_n Posted on Thursday, April 18, 2013 - 09:05 pm:        looking for a front pulley for s1   Littlebuggles Posted on Friday, April 19, 2013 - 12:41 am:        How many teeth do you want on it? I have a couple Sportster pulleys sitting waiting for a machinist to cut them down. I think I have a spare 28t, and maybe a 29t. Since my jobs get "backburner status" I've got no problem taking it back from him, just means he doesn't get a cut for me selling a low weight version. If it will suit your needs I don't think I paid more than $25 for it and can pass it on to you for that plus shipping. -Mike (Message edited by littlebuggles on April 19, 2013)   Littlebuggles Posted on Friday, April 19, 2013 - 04:21 am:        Here's some figures for your consideration, copied from Serialk's X1 winter rebuild thread in the Old School section... Some figures from UKBEG site on ratio's: A = 29 TOOTH B = 55 TOOTH This is the "normal" UK spec and gives an overall gear ratio of 3.034. Top gear - 24.02 mph/l000 rpm giving a theoretical top speed of 163 mph at 6800 rpm. Fourth gear - 20.36 mph/1000 rpm - maximum speed 138 mph. Third gear - 16.80 mph/1000 rpm - maximum speed 114 mph. Second gear - 12.19 mph/l000 rpm - maximum speed 83 mph. First gear - 8.93 mph/1000 rpm - maximum speed 61 mph. At 80 mph in top gear the engine is running at 3300 rpm. A = 29 TOOTH B = 61 TOOTH This is the UK engine sprocket with the US rear wheel sprocket to give an overall gear ratio of 3.366. Top gear - 21.66 mph/l000 rpm giving a theoretical top speed of 147 mph at 6800 rpm. Fourth gear - 18.36 mph/1000 rpm - maximum speed 125 mph. Third gear - 15.15 mph/l000 rpm - maximum speed 103 mph. Second gear - 11.00 mph/l000 rpm - maximum speed 75 mph. First gear - 8.05 mph/l000 rpm - maximum speed 55 mph. At 80 mph in top gear the engine is running at 3700 rpm. I believe the stock gear on (U.S. model) tube framed Buells is a 27/61... seems like anyway. Pretty sure I've got that 29T, now that I think on it a bit, can prolly swing by the shop and check on it this weekend if you're interested.   S_one_n Posted on Friday, April 19, 2013 - 09:06 am:        I'm interested in the front with either 27 or 29. I have a 61 rear. Thanks for the help and info.   S_one_n Posted on Monday, April 22, 2013 - 03:50 pm:        I grabbed a new one on ebay. Thanks
