Re: Anyone ever fit a set of flatsides carbs?
Not sure I'd want to throw down $4000usd on a motec400 just yet, or ever, but that would be cool to have efi.
Would be really nice on my road NC since I ride up in the mountains where the elevation changes quite a bit. Maybe a motec will pop up on craigslist or ebay.
I just looked over Luke Millers thread again. Those carbs seem like a bitch. Hope he can find the right needles and figure out how to tune them. There's some good photos of those there. I'm guessing you would have to make up some brackets to hold them in place and linkages for the throttles. Doesn't look like there's much to get made up. If I do, I'll look into getting a couple sets made.

If you can get links machined it will be quite easy to do as the flatslides are not the same as the CV's and have a rod with a treaded hole in that the slides fasten to.
Ive re racked FCR's and TMR's and you could easily make two new rods that conect to links.

I think the trick is getting all of them to open up at the same rate.
I also found some more info in this thread with some pictures showing how they're put together. http://retro.400greybike.com/topic.asp? ... hichpage=1
