Ådne95 Posted August 28, 2015 Share Posted August 28, 2015 (edited) Hi! Got a good offer on some 38mm mikuni roundslide vacuum carbs from a Yamaha FZR(i think)1000 today. ~£100 and they come from a bike who has only went about 20k miles no need for rebuild yet, right? There wouldn't be any problems using those on my '86 1100EF? Except maybe having to modify the intake? Also, what size are the original ones? Haven't got the bike home yet, so can't check...

vizman Posted August 28, 2015 Share Posted August 28, 2015 aren't the fzr ones downdraught type? Quote Link to comment
Gixer1460 Posted August 28, 2015 Share Posted August 28, 2015 They are and the spacing at 86 - 92 - 86 is way off!Sorry - walk away from the dark side Quote Link to comment
Ådne95 Posted August 28, 2015 Author Share Posted August 28, 2015 aren't the fzr ones downdraught type?I was told they would work, but thought I'd check here first I'm sorry, but I'm not sure what a downdraught carb is? What differs from other carbs? Looked normal to me, but I'm only used to twosmokes Quote Link to comment

Gixer1460 Posted August 28, 2015 Share Posted August 28, 2015 (edited) Good illustration of differences - ignore that they are Keihin FCR's! _ the angle of the inlet and float bowls is the important thing Edited August 28, 2015 by Gixer1460 Quote Link to comment
Ådne95 Posted August 28, 2015 Author Share Posted August 28, 2015 Aah, I see no, they were horizontal I'll see if I can get a few pictures and measurments of them Quote Link to comment
vizman Posted August 28, 2015 Share Posted August 28, 2015 they might be fazer thou ones Quote Link to comment
Ådne95 Posted September 2, 2015 Author Share Posted September 2, 2015 (edited) Sorry for bad pic, it was all I could get now. They're 6mm further apart than gsx carbs, so I'll just have to make a intake "manifold" with a slight angle/bend On the other hand, I came across a set of 34mm mikuni flatslides from a gsxr, would that be a better option?

Gixer1460 Posted September 2, 2015 Share Posted September 2, 2015 Would be a near stock swop - virtually no mods required except jetting! Quote Link to comment
Ådne95 Posted January 18, 2016 Author Share Posted January 18, 2016 Whoops, forgot I made this thread. Got a closer look at a similar set of carbs the other day, these were off a fzr1100 that has only done ~11000km/6600miles. I opened one of the float bowls, looked brand new. Only 6mm different offset on the two inner carbs iirc. In that case, making a new intake for these would still be cheaper than buying another set of carbs. I might also be able to get my hands on some 36mm keihin CV's from a yzf600r, would that be better? Quote Link to comment
