Albie1200 30th September 2005, 00:21 You will have to take the carb off to drill out the mixture screw plug. As far as jet sizes, read jetting 101(much better description than I can give). RoadKingMoe 30th September 2005, 00:41 Literally hundreds of Sportster owners, some who had never turned a wrench before, have successfully used these instructions (http://www.sportster.org/tech/carb/rejetting.shtml) for Stage 1 rejetting. Not everyone winds up with the recommended starting point jet sizes after final tuning. daesdaemar 30th September 2005, 00:50 I drilled out the mixture plug, adjusted the mixture screw, and replaced the pilot jet without taking the carb off... maddog 30th September 2005, 00:54 I drilled out the mixture plug, adjusted the mixture screw, and replaced the pilot jet without taking the carb off... I did too. It would be a help though if you had a bud to hold the carb when you're drilling a hole in the plug over the mix screw. I helped a few guys with stage one jetting. What worked for them was a #45 slo, 2 and a half out on the mix, and leave the main alone. xena 30th September 2005, 00:58 You said jet kit but which one? Theres a lot of them, but the kit itself should come with directions and a basic starting point for your particular application. I removed the carb because I put in a dynojet kit which involves opening the top and working down in there. Some acrobatic people may be able to do that with the carby on the bike, but not me. thatbikerguy 30th September 2005, 00:58 Tnx. for the speedy replies!! I'll check out the links now.

I just did that with my wife's Hugger, as well, but you have to be careful not to scratch the rocker boxes, or pull the choke cable or hoses too tight. Mr Jimi 30th September 2005, 01:01 I hope this helps you? Stevo posted a ( jetting 101 ) and here is the link, I hope it works for you? if it dont do a search in the search box on here http://xlforum.net/forums/showthread.php?t=4465 RoadKingMoe 30th September 2005, 01:10 :doh I've got the Screamin' Eagle "Dynojet Kit" :smoke Just MHO, but if you haven't opened it, I'd take it back and just buy a #45 slow jet - 27170-89 and a #175 main jet - 27090-89 and a #180 main jet 27114-88 thatbikerguy 30th September 2005, 01:26 Just MHO, but if you haven't opened it, I'd take it back and just buy a #45 slow jet - 27170-89 and a #175 main jet - 27090-89 and a #180 main jet 27114-88 What about the spring and other crap that comes in said kit? :doh RoadKingMoe 30th September 2005, 01:31 I don't believe in changing the spring... or the emulsion tube... or drilling the slide... (see my rejetting instructions) or for that matter changing out or adjusting the needle unless the dyno results tell you to. I've done those things and didn't like the results. I've also fixed driveability problems for many by having them put the factory spring back in (or replace it if they cut it) and buying a new diaphram/slide assembly if they'd drilled it. thatbikerguy 30th September 2005, 02:33 Okey, dokey!! thanks, wish me luck... Whenever I decide to do this. thatbikerguy 30th September 2005, 02:48 So, The carb dosen't come completly off. Good!! tcspannerwrench 30th September 2005, 03:06 So, The carb dosen't come completly off. Good!! it simply pulls out of a rubber boot i left my cables conected although i did scratch the valve cover just wrap a towel around the area to avoid this. also i agree take the jet kit back i got a 45 slow and a 190 (stupid dont do) for two bucks a peice from a indy shop i also used a 5 for a dollar washer to shim the needle but i wouldnt do that untill you do the slow jet only then follow stevo's jetting 101 balpo 30th September 2005, 03:37 You can read my experience under the NRHS forum for tax paying on a rubber mount 1200. You can do it, but READ READ READ Stevo's and other accounts first. Make sure you've got all the tools, parts and supplies first. And soak any bolts or nuts that you have to remove in PBblaster overnight. Moker 30th September 2005, 03:57 Just MHO, but if you haven't opened it, I'd take it back and just buy a #45 slow jet - 27170-89 and a #175 main jet - 27090-89 and a #180 main jet 27114-88 stupid Q is there a way to check what you have in now? are the jets labled? xena 30th September 2005, 04:27 Yes Moker. The jet size is stamped on the top of the jet itself. The numbers are small, but they are on there. http://i12.photobucket.com/albums/a203/sporty04/stock175.jpg RoadKingMoe 30th September 2005, 04:37 TBG has an '03, so that's pretty well known. Kev posted some size numbers out of an '04 manual, but they look to be the same as the '03... maybe a misprint. I'm curious as to what part numbers an '05 or later manual would show for the jets. If they aren't some new proprietary Harley items, you can look them up on nightrider.com. Moker 30th September 2005, 04:48 thanks, appreciate it :) |
