Looking to fit a 6 speed transmission to my S1W. Anyone done this? Any info on Revtech/baker or any other manufacturer? Anyone got one to sell? All info appreciated. Thx | ||

It's expensive, but fairly straight forward. Baker is the only manufacturer I know of for a 6 speed for Sportsters and Buells. There is a portion in the casing you have to cut away, but baker includes a template for you to bolt in and cut around IIRC. Much cheaper option is to go to a higher tooth front pulley or lower tooth rear. | ||

Or you could also use an '04-'07 XB12 front primary sprocket and chain to lower your ratios about 11%. The trade-off for the primary or pulley change is torque, in the lower gears especially (not engine torque output, but effective torque from gearing). | ||

^^^ +1 / I have the larger tooth front pulley on my S2, it runs great for long distance riding and highway, its a noticeable drop in RPM, but does not change the fun factor at all, and I do not find myself randomly lifting the shifter pedal looking for the next gear. much easier and maybe the same benefit. unless of course you are also after the bragging rights to "..and its got a Baker 6-speed.." yep that's almost cool enough on it's own to spend the money!!! but if you are looking for the cheaper, quicker, easier fix with same benefit, swap your front pulley and press on! of course I have not compared RPM per gear specs across the board for each gear, so not quite sure what a Baker 6 will do for you in the first 5 gears, but of course with the larger front pulley you get the effect in every gear, but I really don't see a down side to it on my S2, in your s1 where you may want to hammer through the gears enjoying all the torque available you might notice a little loss for your top end gain, again, not sure what the ratios are in the Baker 6 though. | ||

Thanks for the feedback, i'd only consider it if one came up at a bargain price but i doubt it will. Revtech website says they do one too but i think i'm gonna try the larger front sprocket. appreciate all the advice  | ||
| Firstbuell |
if it even exists, would you trust a RevTech unit? pricing? | ||

That link is to trans for a Big Twin, not a Sporty/Buell. | ||
| Firstbuell |
exactly even if it was for XLs, do I trust a lower-level chopper site's evaluation of an advertiser's goods? NO! (Message edited by firstbuell on November 17, 2014) | ||

I went from a 27 tooth to a 29 tooth front sprocket on my S3T and love the difference it made. Didn't notice much difference on take off but nice change at highway speeds. Bought it on Ebay for 10 bucks with 10 bucks shipping, it was from an 01 Sportster. Best 20 bucks I've spent on the bike. | ||

I got the Baker kit about half off MSRP from eBay. It comes with the Billet Trap Door, and the Smooth Shift Kit with the bolt-on detent plate. Makes shifting a lot better, practically Japanesish. The rpm drops by 500 at about 80 mph (indicated.) Eighty mph sounds really fast, but its common here for the left lane. To get an equivalent rpm drop in high gear takes a pretty big front pulley...well, I worked out all the gearings on a spreadsheet, just can't find it right now. With 5 front pulleys, two rear, plus alternate primary sprockets, there's a lot of possible ratios. There's also a kit called SportGear, where I think only 5th gear is swapped. | ||

ah yea i misread link, just seeing whats out there. Jayvee I'd definitely be interested in seeing the spreadsheet on the gearings if you find it, i may have sourced an XL6 pretty cheap | ||

I have 105,000 miles on my 96S1, sell it?From my cold, dead hands. I bought it in 1997. I have visited this subject many times over the years. In 2010 I bought an 09 1125 CR. This bike has 23,000 miles now. My conclusion is that the S1 gearing is perfect for city metro duties and the CR for the open road. On an 1125 you can roll down the road all day long at speed and be using less than 50% of the engine. My S1 is dyno tuned using a Mikuni, Crane, D&D, Penske, GP Suspension configuration. My mindset for speed was shattered with the CR. With the prices of used 1125's these days.... | ||

I too, find myself often looking for a 6th on my '02 S3T. Opposite of having to downshift to 5th too often on my Ducati 907IE as it lugged, not quite doing a comfortable 80 mph. Since I do have the Race ECM I believe I will go the larger front pulley. Anyone have an opinion on whether the Race ECM adds to heat factor? I guess I will have to get serious about shopping for an oil cooler. The Race ECM was on the bike when I got it and it seemed to run hotter. I am wondering if it caused the ETS to go out. Unknown how long it was on before I purchased. Thanks for the info guys. | ||
| Phelan |
Odd that the race ECM is making it hotter, if that's the case. Most often the race ECM makes the bike run cooler by squirting more fuel than stock. | ||

Maybe it wasn't the ECM, maybe it was the ETS. The ETS didn't go instantly. The red engine light would come and go randomly. I was forced to get it fixed when it started cutting out and backfiring. There was one busted exhaust mount bolt so I thought there might be a leak. BTW, it would start and run fine then after it got good and warm would act up. Purchase was late May/early June. Went to shop middle of August. With a 2 week delay for Hawaii in July. Had to scratch my brain hard. Was just 2 years ago. The stock ECM came in a box with other stuff when I purchased, so I just had the mechanic change it in case that was the problem. So if the ETS read hot it would add fuel. If it read cold would it cut fuel then run lean making the bike run hotter? Thanks for all the help guys... (Message edited by Ducley on November 21, 2014) | ||

For gearing ratios you can try this calculator: http://www.gearingcommander.com/ | ||

If your ETS is failing, the bike will run on one and sometimes two cylinders. Lots of raw fuel pouring out the exhaust and your plugs will foul quickly. Consider changing out the O2 sensor while you are doing the ETS. Easiest way to remove the O2 is to bust off the back end, then put a socket on it to break it free. American Sport Bike sells both.
