I have a couple of motorcycle carbs laying around. Nice ones. I have a pair of FCR 41 mm carbs. This is what the high end race bikes ran before they went FI.
Here's my dumb idea... I have a set of 2 into 1 manifolds, and some carb spacers that fit them. I can have a muffler shop weld me up a 45 to the manifold and then I can use a silicone hose to mount the carb to the manifold. I can then make some sort of brace, but I will need to figure that out once the manifold is done. They have two place cable wheels on them already so I can make a single cable with the motorcycle adjuster on the first carb, and then an adjustable crossover cable on the second. Sort of like the new cable linkage that people are making for the regular Weber carbs. These carbs are new, highly adjustable, and jets are available freely at any motorcycle shop. Can anyone blow holes in this idea? Why won't it work? The only thing I can think of is that the 41's may be too large for my stock 2 liter. I could build a bigger motor later if that's a problem (IMG:style_emoticons/default/smile.gif) Any thoughts? (IMG:http://www.914world.com/bbs2/uploads_offsite/www.spracing.ch-9147-1304391327.1.jpg) This is a 39, but the carbs look the same on the outside other than the sticker. |

Got my manifold tubes bent this morning, and have all the hardware to mount the carbs. Just need to get the tubes welded to the flanges on Monday.
Next week I will be starting on the bracket to hold the throttle cable to the case, and then I can work on mounting it to my stock 914 cable. I think I am going to pick up a set of the FCR idle mixture thumbscrews. They replace the idle mixture screws in the bottom of the float with thumbscrews so you can make adjustments without a screwdriver. That should help me a ton since I am not sure I will be able to get a screwdriver in without loosening the carbs and twisting them up. I am starting to look for an O2 sensor for tuning as well. Progress is happening. |
