jrhendryx Posted February 26, 2008 Posted February 26, 2008 what size are the stock carbs on the 1977 xs650? what are better options? mikesxs.com is a great place for anything related to the xs650, and also some of the other xs models. he has some aftermarket carb setups and i think he also has some big bore cylinder sets.

jeepurz Posted February 27, 2008 Posted February 27, 2008 runningvm 34's roundslides on two xs's, I buy a lot from mikes , never a problem, but on carbs try 650 central, especially if your running a modded motor , 650 central will send them tuned to order for your mods, you wont have to tweek them . no experience with mikes dleorotto's so I cant say how they compare. hope this helps. http://www.650central.com/
jeepurz Posted February 27, 2008 Posted February 27, 2008 also, your carbs should be bs38's, and should look like this.
socalyamaha Posted February 28, 2008 Author Posted February 28, 2008 well, heres what i'm trying to figure out. i know MC companies send there bikes out in to the world running lean. so my question to you all is: should i stick with 38mm carbs and increase the jet size? or buy a brand new set of 36mm Mikuni's?

I know 1980's and later are lean, but I think that 77's were not.
jeepurz Posted February 29, 2008 Posted February 29, 2008 you will absolutley love roundslides, easy to tune great throttle response. http://www.650central.com/ linked mine together with a peice of threadrod, youll have two choke levers but only one is needed to tickle it.
