R1000 Posted November 13, 2007 Share Posted November 13, 2007 It seems there is finally a solution for carbed bikes that provides the perfect air-to-fuel ratio, all the time. I can’t use it since it would make my bike too powerful considering the expensive mods that are already done . Don't make the same mistake as me and; port the head, change cams etc. to increase power, which is just a waist of money when there are better solutions. http://www.thunderproducts.com/dial_a_jet_techpaper.htm Anyone brave enough to admit using this kit ?

CxBXR Posted November 13, 2007 Share Posted November 13, 2007 Im not sure "The end of fuel injection" is the correct title, how about "The beginning of fuel injection" This system is ages old, & from what I hear are a pain to dial-in properly, lots of time tuning them old carbs. Was/is widely used on drag/racing bike's, designed to richen midrange & top-end. Dial-A-Jet has even been successfully installed on fuel injection machines. One Arctic Cat dealer wanted to run performance pipes on a 580 EFI. The existing fuel map worked fine on the bottom end and midrange; however, the top end was extremely lean. Dial-A-Jets were installed on the throttle bodies. Fuel was pulled from a remote float bowl (available from Thunder Products) attached to the return line of the fuel injection. Dial-A-Jet cured the top end lean condition. The set-up worked great, yielding a crisp broad power band! The Dial-A-Jets could be adjusted for temperature, altitude, engine load, or fuel quality. The installation was simple and effective. More than 3,500 trouble free miles have been logged on this machine. Quote Link to comment Share on other sites More sharing options...

silverbird1100 Posted November 13, 2007 Share Posted November 13, 2007 I just ordered them for my F4. Seems pretty legit, if it actually works I can't imagine how awesome it would be to not have to fuck with my constantly bitchy carbs. THANK YOU R1000!

tomek Posted November 13, 2007 Share Posted November 13, 2007 I was interested for a second,but I need something that can lean the mixture.We have carbed yzf1000,it runs like crap in high passes of the Rockies.But this device works the other way,,,,,,,,, Unless I tune it for 10000 feet and use Dial a Jet for my "normal" elevation,,,,What you say cbrxxquad ?

runner Posted November 13, 2007 Share Posted November 13, 2007 A comprehensive test would be good. Maybe MCN (Motorcycle Consumer News) would accept the challenge... Quote Link to comment Share on other sites More sharing options...
cbrxxquad Posted November 14, 2007 Share Posted November 14, 2007 The one I had enriched with increasing flow due to eduction. What you need is a needle that is larger on the end to lean at 3/4 throttle and a smaller main. Quote Link to comment Share on other sites More sharing options...
