GL1000 carbs reversed!

Postby 75Batwing » Thu Apr 30, 2015 12:27 am



I am giving my 1975 GL1000 a make over. I fabricated a handlebar adapter so I can run 1" Harley Bars and Harley Controls, A Harley Seat, Custom Paint, and now I deleted the center carb plenum box and reversed the carbs so they stick out instead of in. It gives it a really tough look. Just wondering if anyone has ever tried this, and if I will have any problems with performance? I fabricated intake manifold adapters so it reversed the mounting holes so they stick outward over the valve cover, then mounted the carbs. I am fabricating scoop air cleaners to sit on top of them now, and figuring out how to make a push pull throttle rod assembly and choke assembly. I don't think it will change anything performance wise, but haven't seen anyone else even try this. Any imput would be appreciated. Thanks Guys! 8-)

I thought the carbs had been put in their to keep them warm, and out of the way. If you have them sticking out, they would be cooled by the wind - this may be alright in the summer, but when it gets cooler, there may be some problems with fuel consumption. Don't know, but it got me thinking.

Interesting thought, and yes, you might have an issue with carb icing for that same reason. That said, I have seen a picture - somewhere - of a GL1000 with carbs sticking out and external air filters on the sides, so it's certainly possible to do.

Alot of people put vw dual carbs on. It's tricky to jet but done right give you more he and torque. Never seen anyone do it with factory carbs yet. Hope icing isn't a problem. Will cross that bridge when I come to it I guess. Lol

What's you're plan to get fuel to the carbs since there's no plenum anymore? Looks cool but seems like there'd be a lot of stress on the "ears" of the manifold where they bolt to the head.

I will run fuel lines to each carb. I'm fabricating a support bar to attach to the carbs to give them support and to mount throttle linkages off of.

Ram air would be interesting if you can keep the bugs out.
