Hey everyone! Sorry for the double post, I heard great things about this site, so I thought Id post my question here. I just bought a Cyclone that had some starting issues.. I got it started after cleaning out the carb and changing the gas. First off, the previous owner put a Vance and Hines exhaust on it along with a S&S Super E carb. It is not jetted as when given a quick open throttle, the bike dies out(if held there). I'm not entirely sure how one sounds normally, so I cant tell if its erratic. However it runs a lot nicer when its hot if that means anything. I just bought a high range jet kit so I could start jetting. I also just checked the spark plugs and I was definitely in need for new ones. They were both entirely black when pulled. Which I assume means its running Rich, but with the throttle issue I could have sworn that meant lean  Another thing I noticed is after high revs, some smoke comes out of the breather tube. I'm not sure how much smoke is supposed to come out, but does it make sense the higher I rev, the more smoke comes out? Would really appreciate the help, Thanks.. M2who | ||

The proper air fuel mixture is what you need. It sounds like you are dumping a crap load of fuel when you get on the throttle. I am sorry but I do not know much about the S&S addition to these bikes. I would call S&S they are very nice with customer service and they do KNOW BIKES. | ||

If the bike has sat for a long time, the breather tube may be just moisture boiling out of the crankcase. Speaking as somebody who has restored a LOT of bikes in various conditions, old stock carbs are hard enough to get cleaned and jetted right. Aftermarket carbs would be a whole 'nother level of pain. So like Bert says, see if S&S can get you in the ballpark to remove that as a variable, then try and chase down other problems (like getting the carb clean and looking for intake leaks). It's doable, but it may take a LOT of time and you will develop a lot of expertise. It took me months to learn to do it well on 2 stroke dirt bikes, and I can't count how many times I've pulled, cleaned, rejetted, and replaced carbs. | ||

Smoke from the breather isn't really normal but if it has been running REALLY rich for a long time, the oil may have been fungled up with gas. Does the oil in the tank smell "Gassy"? I'm thinking once you get it running right and change the oil, it may improve. | ||

Can you get it to run long enough to take it for a ride? If so, go for a nice 10-20 minute ride with little to no idling (difficult, I know) and check the plugs when you get home. Their color will let you know what problem you are having. | ||

For the most part, I'm believing you are all right. It seems like I am choking out the engine since the past two plugs I've used were black from the carbon. I will get in contact with S&S to see where I'm at. In the meantime, with this given knowledge how should I get my carb? I dont know what 42 means or anything like that. I know the sizes based on what it says on the bolt, like 0.031 or main jet sizes 0.77, etc. My main jet is currently at 0.77 and pilot is at 0.033 | ||

San s should be able to tell you what jets to use or at least get you close | ||

I run an 89ci S&S motor with a "G" carb, .0295 pilot, .068 main. That's a lot more air and much less gas than you are trying to do. Look at your accelerator pump with the air cleaner off. Turn the screw in/out until it doesn't work, then back it off until it just works a little. Start there. Here's the manual: http://assetcloud02.roccommerce.net/files/_sscycle /8/9/5/510-0251_super_eg_series_shorty_carbs.pdf | ||

Livers, I posted a new thread (http://www.badweatherbikers.com/buell/messages/476 23/790109.html?1469283999). My main jet is 0.72 and my pilot was at 0.0295. I changed the pilot jet 2 sizes up to a 0.032. it throttled a lot better with the bigger jet. When I cracked it open (the throttle) it wasn't bogging out. It did have a slight delay, but wasnt bogging out 90% of the time. I was adjusting the accelerator screw when it sputted, carb farted, and died. I haven't been able to get it started since. I did a plug test and found there is no spark now. There was fluid on the plugs when i pulled them. I also charged the battery, it should be at 12.6-7V since I drained it trying to start. It turns over, but don't want to start, not even with starter fluid. I might have blown something when the carb farted as someone said. When I have the opportunity I'll work my way down the line and see if the ignition coils are okay. | ||

I apologize for not adding the disclaimer about checking the pump action with the motor NOT running. I assumed you knew what you were doing, my bad. | ||

lol not necessarily, kind of just jumping in. | ||

A wet plug will not fire, we used to heat the tip of the spark plug with a propane torch till it was good and hot to burn off the gas. | ||

Well I called S&S cycle today. They told me my jets were too big and should try a 0.0285 or stick with the 0.0295 (depending) and try a 0.68 main jet. Now this makes since my plugs were showing a rich condition but the carb was showing lean conditions. So I'm going to change the jets to a smaller size when they come in, however does anyone know what size air bleed I should have? currently 0.68 is in the air bleed and I have a Vance and Hines SSR exhaust (I think thats the name)? |
