If i park my 1979 cx 500 it leaks gas out of the drian tubes that come out of the carbs,the bike runs fine and dose not leak when running. I craked open the little side screw to drain the gas out a bit but makes no differce. .So i have to shut my petcock every time. Harbri.

Well first you should shut your petcock off everytime. That's why it's there.



If both are leaking then most likely you have a crack in the overflow tube in the carbs. It's easily fixed with solder.



But you could also turn your petcock off with your bike on the centerstand, drain the carbs, turn the petcock to on and tap the bottom of the carb bowls with the handle of a screwdriver. Then see if they continue to leak. If so it's your carb bowls.

Harbri, would you take a few minutes and edit your profile to include your location, and edit your signature to include the bike model and year.



You have made several posts on various issues, so if you can give us some history of the bike, it will make it easier for us to help.



From what I am seeing in your posts, you have quite a few issues. In the case of this leaking gas, I highly recommend a full overhaul of your carbs. Go to the Quick Reference thread in the General Discussion area to find a whole lot of great information.

Quick fix....ride at 55 mph, turn off fuel, until engine starts to cough, then open fuel tap.



This allows the needle and seats to operate almost all of their travel.



Also, shameless plug for Larry's carby book, most bikes haven't been touched in years, and the carbs are to blame for 75% of all issues, even some "electrical" issues.

That's a nice shameless plug. Last week I think Larry said he was down to 9 books. But don't worry he's printing more and I believe in color.

I just got an 81 GL500. It does the same thing but hasn't run yet. I thought I'd write this before I do the carbs.



Where have you guys found the best deal on carb kits, i.e., most complete, best quality, best price.



Next.....and I can't think of a better place to put this.....



Both of my other GLs run well but have a notable lag of go on the very low end, Just starting off in 1st. gear they lag a second and as soon as I begin to open the throttle they leap forward. Is this common to the CX-GL carbs and has anyone figured out a way to make the transition from idle to low speed without the sudden lunge ?



I was imagining longer transition slots in the throttle bodies but wouldn't want to mess up my carbs unless it was on proven advice.



Thanks Gang

I am by no means a carb guy, but thats is not normal sounding to me, both my CX500 and GL500 were/are not showing any signs



of lagging off the line, sounds maybe like air jet? Dirty carb? Larry....calling Larry....where are you?
