My Sportster is leaking gas from the carb!
Hey everyone, I just picked this bike up a couple weeks ago and I noticed a problem. It's a 2000 XL 1200 Sport. It has gas leaking out of the accelerator pump rod area. It leaks a good bit because I have gas sprayed on my pipes after I'm done riding and it puddles up when I'm not riding sometimes. Maybe it is when the float bowl is full? Is there a way to fix this? I seen this system and was wondering if it would solve the problem? http://www.boyesen.com/twinshot-vtwin#q3 Any help is appreciated! Thanks

I was going to pull the bottom of the carb off but those pesky brass screws are easy to trip!! Looks like I'm going to work on this when I have more time on my hands. I figured buying an older bike was going to mean it would need some work but I didn't think it was going to be this much. It's still worth it in the end though!

Hang in there Tex, motorcycle carbs are all pretty much the same, and pretty easy to disassemble and reassemble. You can do the accelerator pump without taking the bowl off.
What brass screws are you talking about?
The jets and idle mixture are brass, float bowl and accelerator pump screws are steel as well as cable mount screws and topcover. Never had a problem with stripping anything on a carb, myself.
Just be careful with the vacuum chamber diaphragm.
You can do it!!!!

I just ordered a carb rebuild kit which will get here in a couple days. John, the float bowl and accelerator pump screws are brass on my bike. Not sure why, maybe it's because it's an older bike? They seem real tight and I know I stripped the head off the one. I'll just take them out and replace them with some steel screws. I got the basic mechanical know how so all of this won't be much of a challenge. I did just get my carb rejetted by a guy since I wanted him to dyno tune it while he installed the jet kit. Getting the bike running close to perfect wasn't my skill level.

Interesting, my bike is a bit older (1991) and has the common steel screws, someone probably changed them out. Put a drop of WD40 or similar and let them sit for a while or longer, then try them.
Harley owners love to customize, I've swapped a lot of the crappy stock bolts for allenhead or buttonhead stainless, maybe the guy before liked the brass look.
BTW, If you had it rejetted, the float bowl was recently taken off, so maybe the mechanic who did the rejet should have checked the accelerator pump too, and mentioned the brass screws.

Yea I don't know if he swapped them but I don't like it at all. The one screw that I stripped the head seems like the threads are stripped too. I guess I will have to drill and tap that one, if thats the right way to do it? Eventually I would like a replace a good many of the screws that have rusted heads.
