Hahahaha hi Eddie. All this speculation and problem solving over throttle pull length . . . I'm running two identical 13mm SHA carbs (or at least that's the plan right now) so this will not be a problem for me. I did order one of the CNC halves that Tyler linked to in my WTB thread. If this build goes well I may do the dual carb dirty deed on my grande as well . . . but use a much bigger carb on the small half. The pinasco limits you to an 11mm hole in the small side of the crank. So IMO anything much higher than a 13mm carb is largely useless. Similar to the restriction on the stock spigot (but hey at least you have two of them on a dual carb setup). But, the CNC halve shoots right up in front the bearing/crank altogether so you can go pretty big on that carb. I was thinking of potentially pairing that with the new 46mm malossi and stock cases cut with their purpose built cutter. But that's all later on, maybe.
Brian said he is hooking the throttle for his separate carb up entirely separate, kinda suicide style I guess? Smash on the NOS at full throttle kinda style maybe?
Whoever mentioned malossi throttle splitter leaving you stranded . . . the one that came with the pinasco seems to be really good quality. I don't really see it being likely to fail. The little cam/slider fits nicely in the sleeve and it seems to be machined well for normal sized throttle cables. Yeah some soldering will be required but that's all fun. However I could see it being cool to just have a hard soldered Y shaped throttle. It may prove to make the sleeving and routing challenging but maybe even less of a chance of failure.
I've attached some pics of the splitter, I think it's really damn cool. And a pic of the engine mocked up kinda, just for fun. Was considering making a separate build thread but I think I'll just keep updating this one and encourage other dual carb vespa peeps to post their progress as well.
