Hey guys, been visiting this site since early last summer before I bought my S2. I think it was your posts that convinced me to buy it. Well, I think I'm ready to change a few things. Just ordered the Force race pipe and intake tuesday. I've been doing research and looking for a jet kit for it. Having limited knowledge of carbs makes it difficult to find when you don't know what you are looking for. Are all carbs (S1,S2) the same??? Can I use a kit for a Sportster of the same year??? What are my best options? | ||

You don't need a kit, just a 45 pilot jet and about a 185 or 190 main. Set the low speed screw to 2.5 turns. Lots of info in the KV and elsewhere. The Force pipe isn't going to get you much except a lot of noise. The stock S2 has a stock Sportster motor. The stock aircleaner actually flows more air than the Forcewinder intake. Looks better on an S2 to boot IMHO. In order to take advantace of a Force pipe, new heads and pistons would be in order. The stock header and a V&H work real well and sound great. Opinions vary of course.... Brad | ||

If you still have the stock CV-40 carb don't let it intimidate you. It is easy to work on and arguably one of the most reliable ever made. You can see the details on working on it here: http://www.nightrider.com/biketech/hd_cv_mods.htm I did the #45 slow speed jet change on a 2000 M2 and the results were simply wonderful, no other way to describe it. All I did was change the slow speed jet, I did not do any other other work mentioned there (drill the slide, replacing the slide or main jet, etc.). If you find any worn/damaged parts or gaskets you can probably get the parts from a carb kit for a Sportster. If you carb is original to the bike some of the rubber parts like the slide diaphram may be due for attention. If you have the carb off it is always a good idea to replace the rubber seals on the intake manifold. Those harden with age and are a little prone to leaking. Replacing them every 2-3 years is not a bad idea I'm told. The details on getting at the *%$@# bolts to get the intake manifold on and off are in the KV too. It gets easier after the honeymoon. :>  Jack | ||

Brad & Jack, Thank you both for the info and "IMHO" are very appreciated. Thanx for the link, that web site is very informative. My S2 is 12 years old with 6,000 miles on it. I've put half thoes miles on it since August '06. I do think it's a good idea to replace all the rubber seals and gaskets. The V&H with stock header was my origonal plan. But later ($next$winter$) I would like to get Stage II heads, change out the cams, add some timing etc... Thinking "down the road", I ordered the Force exhaust and you can't (so I'm told) use the stock air box. Do you think I would net more with the V&H than stock with the Force intake and exhaust?

You're doing a wonderful thing, keeping that old S2 alive and well and not letting it become a donor for a chopper. We here like to help with anything that keeps an old Buell going. I was perfectly happy with the performance of my M2. I think it had better heads than the S2 but it had all the power and torque I wanted just as it arrived. I changed the stock bread box air cleaner out for a billet aluminum air cleaner with a K&N element. You can see that here: http://users.adelphia.net/~jackerbes/Buell/Buell_M 2.jpg That probably had less restriction than the stock system but the high speed jetting was still okay with it, it did not get too lean. That air cleaner was much better looking and just out of the way of my knee (32" inseam). I did that more for appearance than performance. It was a little noisier at full throttle but I rarely ever heard it. I was getting all the joy I needed from what happens down around 4,500 RPM with an occasional higher spurt. I defer to the performance experts here and guys that have done it on your questions. But it sounds like you're headed for a nice running bike. Jack |
