I want to thank Scott for the information provided on this common Road Star puking problem. I was recently on a ride with about 12 other bikes (mostly Harleys) in West Virginia. The temperatures were 37 and 38 degrees. It was prime puking weather for the Roadie. It didn't fail me either. It always started but only after a puking session and a black smoke display. It was the most embarrassing when we were leaving the Harley dealership.
Well, after receiving your email, I installed the overflow line on the carburetor and threaded it to below the bike. If it wants to puke now, it will be on the ground and not on the hot engine. I also started using premium gasoline. When you take the Ethanol out of the picture you have really solved the problem.
I did opt to make other impovements to the bike at the same time. I have always felt that my Roadie ran way to hot. Last year I installed a Jagg Deluxe oil cooler. It did seem to help it to run a little cooler but I didn't get the big result I was looking for. After reading other information on here, I decided to pull out my wallet and do something about this. I installed a Barrons big air kit, Barrons fuel pump relocation kit and a Barrons AIS removal kit. It is amazing how this opens up your bike for air flow. The front, left side and right side are totally open now. The bike runs great and there is no more puking. It starts like a bike is supposed to start when it is hot. This is the way it should have come from the factory. You can see the engine now. I couldn't be happier with my Roadie. This is a great forum and thank you for all the information.

Thanks, Scott, for the carb puke fix inst. I'll be using them this weekend.

Glad you got it squared away,its all about the excessive heat boiling fuel out of carb so when you removed stock airbox and relocated fuel pump it opened up large ares of additonal cooling on both sides of the motor . Thats just what the R* motor needed to cool things off like carb etc that stopped the boiling/puking of ethnol'd pump fuel out of the carb's float bowl thru the vent to atmosphere.

NP,good luck and let us know how it works out.

I had my carb puke for the first time. This is how the bike came from the PO. Is this the hose that needs to be routed to the ground? It doesn't go anywhere at the moment, so if this is where the gas came from (I didn't see it happen), it's pouring right on my pushrod tubes and engine.

Yes.
You can get a longer hose, and route it behind the push rod tube, and down behind the decompression solenoid, and zip tie it to the frame.

Glad you worked it out but I surly don't understand....
"Temp in the 30's was prime conditions to pkuke" I would think temps in the high 80's as here in Fla would be prime. Mine rarely Luke's but I left my hose hanging like humbugs and the rare occaision it does..it shoots over my pipes and onto. My HD buddies boots (actually did once) told him he makes my yammi sick!
Second..I'm not understanding the black smoke? Never experienced that either?

Hi Scott, Was glad to read so many posts about the success you've had with the insulating. I too would like to try it out. Just bought a Roadie about 3 months ago and immediately found the puking prob. I've been pulling my hair ever since trying to figure it out. One thing I haven't read about in all the posts is excessive "clicking" of the fuel pump. When the bike starts to "puke", the fuel pump kicks on and starts clicking for a while. Does that sound familiar? Please help! Oh I'd also like a set of those insulating instructions you wrote if that would be possible. vaquero4cristo@gmail.com
Thanks a ton!

The clicking is your fuel pump trying to make up for all the fuel the system just puked out. The clicking is the pump building pressure.

Thanks for the quick reply! Yeah, that's what I figured... so nothing to worry about I guess right? Do you happen to have a set of the instructions how to insulate the fuel system?
