Tuning Carbs

some say it takes a zen to do it right,
but really you need one or three special tools. the hardest one is the tube thingy...(sorry the name is there just can not get it out). about a $100.usd item
it shows you how much vacuum is at each carb.and from there (pending app) one or two tools to do the adj on the carb's.

but if you do not have the tools needed or the skill to turn a wrench then off to the shop and pay the piper. :ugh:

mechanical adjustments are easier to do and can do them at home, with a little knowledge.
but computers take big money..as you get to pay a shop for everything.

unless you have that $50 million dollar computer, adapters and software..as well as know how to work with it.:eek5:

K you asked for a carb tune theses guys are trying to tell you how to sync the crabs. First do a full carb clean, be sure to put every part back where the manual says. The R1 engine is strange, most engines run richer settings on the inside cylinders, this bike runs leaner settings on the center two carbs and richer on the outer two. Once those are perfect set your float height, meaning make sure all of your floats sit at he same height when they are just barely touching the float needle. Then the idle mixture screws, i would go slightly richer then stock due to strict epa standards. Lastly is the carb sync, you can do it and no it doesn't take millions of dollars of computers to do. Its simple vacuum adjustment.
 
Depending on how how accurate you want to go you can also use a non fluted end of a drill bit to sync em. (This is how a lot of guys do it on sleds) The vac tool is fairly simple to build and like 20 bucks for parts. Personally I would get a carb rebuild kit also and put all new gaskets on em for peace of mind.
