yes sir i would agree... if oyu look for ZR440 artic cat carbs theya re VM 32 and sometimes 30's it is a race sled so they come stacked... i had no idea till i built one this winter for myself.. you can find the carbs pretty cheap... also pulls up under snopro 440 race sled... help ya find em a bit cheaper
Ill check with tim to see if we may have any extras in the shop... he has like 5 of these sleds so i bought one off him and build one for myself this winter... ill check tomorrow when i get in the shop

if you make your own manifold man do me a solid and save the demensions you come up wiht... i have a CB500 that is going to get a 4 to 2 conversion on the carbs

You know I'm loving this. Nice job on the tubing. Did you modify the dyes on your hf bender? Looks like you got -0- flattening. have you tried your carbs in there yet? Keep in mind where the low point on the tank will be. I tossed around the idea of making the front the low point on mine. Decided against it but it would make for some nice long (copper ) fuel lines ;D

Mari- thanks man. Pick it up. Ive been snatchin all the reasonable bikes around here ive been findin on cl.
Troy-thanks brother. Told ya it was a lot like yours. The kinker, what i did was, took a piece of 1.5" conduit and cut 5" pieces. Stuck them on the rollers and dies the "cushion" the tube. The piece on there is 1 3/8" i had layin around to see how bad it would be. Also the rollers were in 2nd to last holes. The bottom does have all the litttle divots. Ima step up to a 1.75 backbone. As for the bungs, i wanna do rear. But if i use the sidedraft weber, ill use front. The colors are already picked out. Rootbeer and brass/copper. As to the copper. Ive been playin with sweating pipe. Will that withstand the heat/vibes from the motor?
