The dreaded gas smell

hoodooman · 07-27-2015, 01:00 PM

i'm turning into a posting machine! 05 1600 classic. I'm getting a gas smell when I ride sometimes, and when the bike is parked in the garage i'll get a wiff sometimes also. i recently went on a long ride with some family and the rider behind me said he thought i was running rich. then another rider rode behind me and said the same thing. now, how could my bike be running rich when there is no fuel controller installed? The engine is totally stock, with cobra long shots and the marble trick to stop decel popping.

I also jacked up the back side of my tank to inspect the weld on the tank mount tab. it looks totally fine. No paint missing, bubbling, cracking or signs of any kind that the weld is bad.

I checked out the hoses on the tank as best I could with having the tank still mounted.

What else should I check?

When you lifted your tank to check the hoses for fuel leak did you turn the key to prime the pump . I found I had a leak at the hose going back to the tank . It's only held by a compression clamp. Priming the pump adds pressure to see where your leak might be . You can prime the pump as many times as you need to and watch for drops of gas. Also check for leaks at the fuel injectors as well . I had a O ring go on my rear injector that I replaced . All is good now !!

This should give you a good start . Others may have more ideas to help you find your issue .. Good luck

thanks! those are great ideas. i'll try it out and see if i find anything.

welp, no such luck yet. my 1600 has quick disconnect fuel lines so they do not use hose clamps. i did prime the pump several times and looked around. didn't see anything. so i took the tank off to try and look around more, still don't see anything... guess i'm gonna put er back together tomorrow and just continue riding the rest of the season. it's been like this for about 9,000 miles this past year so hopefully she'll keep on going!

Yessir, I cleaned and reoiled my K&N a few hundred miles ago. one odd thing, when i took my tank off, i had to put a hose with a shutoff on the fuel pump. it wasn't gushing fuel, but it steadily dripped. maybe that could be causing a problem? shouldn't the fuel pump not leak at all once disconnected?

When you reconnected your fuel line snap connector did you hear an audible click? If not it may not be locked on tight to the tank connection.

With age, that quick connect doesn't hold a good seal. I converted to the hose going directly to the tank nipple using the hose clamp. Same with the other hose with the pressure clamp. Use a real clamp, fresh hoses, check the routing to make sure that there's no rubbing or hose kinks.

What gas mileage do you get from your bike. If its actually running rich, or leaking fuel somewhere, I'd expect your fuel mileage to be well less than usual, about 36mpg for general riding. My 1600 Classic at best gets a bit over 38mpg
