Fuel Injection. 4 Years, 7 Months ago  
I have a 2005 Road Star. Has anyone tried to convert this bike from carb to fuel injection ? Any idea of cost to convert. Tired of popping and back firing. Local shops can't get it right.

Can't be done! An injected enfgine has several sensors that the computer reads to do its job. You could remove an injection system and replace it with a carb; however, to be injected an engine has to be built for the purpose.

It's really not so much that the engine has to be built for fuel injection, as a system can just be bolted on, but as Clifford correctly states, all of the sensors and electronics for it have to be added, as well as a high pressure fuel delivery system to the injectors.

Don't despair... your carb can be tuned to work correctly. And with the help of the savvy carb guys here, you can do it yourself for less than $100.

Re:Fuel Injection. 4 Years, 7 Months ago  
Oh, and let me add this, too... when I modified my intake and exhaust, and knew I'd have to rejet... I trembled with fear at the thought of it, but because of the info I found right here in the clinic, I bought a jet kit off eBay, followed the directions, and darn if it didn't come out just right the very first time!

They have had to un carbon the velves 2 times ($750) each time. The first one was covered by warrenty. The jets where changed 3 times. Still poping and back firing. The bike only has 11,000 miles on it. Inside of pipes ar covered with black smoke. The only change I made was taking out the baffels in the muffler.

I mean this... no kidding. Start over. Get a jet kit, and do it yourself with the instructions from the carb gurus right here. It'll work.

Whoa! Wait!!! You only removed muffler baffles???

Odds are great the carb should not have been touched. If you only removed baffles, it did not need to be rejetted, and you're probably very rich.

Do you know how the bike is jetted? If not , can you find out? Dealers (and anybody else that follows the directions from the jet kits..) jet them really rich. Are you comfortable working on your own bike? If so , we can help you get it right. BB
