jrhendryx Posted February 26, 2008 Share 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 Share 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/ Link to comment Share on other sites More sharing options...
jeepurz Posted February 27, 2008 Share Posted February 27, 2008 also, your carbs should be bs38's, and should look like this. Link to comment Share on other sites More sharing options...
socalyamaha Posted February 28, 2008 Author Share 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. Link to comment Share on other sites More sharing options...
