best dual carb. performance

hi. i,ve got an 86 xr600r. after market slip on exhaust, opened up air box and k&n air filter. allready have gone up 2 sizes main jet. 127? if i remeber correctly. made quite a difference for the good. my question is with 2- 28mm carbs how can i get the most performance i can out of these carbs? moose stage 2 kit? main jet's are the only thing i have touched. i also may be going to 628 bore soon. thanks for any ideas. tim

i dont think there is any such thing as a jet kit for those.

sounds like youve got it pretty close.

make sure both slides open that the same time.

thanks for the quick reply. i,ve looked around and moose has a kit for 85-87. i,am wondering if this would be of any help. they say a stage 2 kit with up to 8% increase. maybe a possibility? what are the difference's or benifit's from stock ? also the secondary carb is a little offset from the primary (slide), if that is matched up with the primary would that maybe give it a little more? thank you for your advice. tim :thumbsup:

you can bend the fork in the linkage so both carb open the same.ive found that they work best this way.

moose kits are just repackaged dyno jet kits and i dont see it listed.they may have it mislabeled.could be xl600?

      38MM Cast SmartCarb. Purchased a couple years ago for a yz250. Don't have the bike anymore, and it has been sitting around for about a year. Used, but in fine working condition. You can also purchase a different needle for different bikes, as well as rebuild kits from their website.
      Asking $250 shipped to continental United States. I can arrange other shipping options at the buyers expense.

      Hey guys I just bought a bike last night. So the seller said the bike will turn on but then die. We didn't try it because it was really late at night and it was raining (seat was wet). But he said if you bump start it, it will turn on and ride. So what do you think the problem is? I just want to make sure it runs... I probably won't be able to bump start it till Saturday (rain)... It's a four stroke, and I know absolutely nothing about them. Thanks.

      I know this topic has been discussed in the past, but I have not found any options available for the new 2018 bikes. I live and work for a new Beta Dealer (Auburn Extreme Powersports) in California, and we are having a difficult time mapping the RR-S bikes for full FMF exhausts. We have tried contacting Beta Support several times for this issue to no avail, and we typically are given the runaround when transferring to techs and secretaries. From what we can gather, the FMF flash is designed for the RR bikes, but not the street-legal counterparts. Every time we try to install the FMF map onto an RR-S errors occur, and the programmer screen goes virtually blank. We have heard through the grapevine that some are using the RR maps on the RR-S with success, but we have yet to try it, even on our own bikes for fear that it will permanently erase or damage the CDI. Any and all help or suggestions regarding this topic would surely be appreciated! Thanks, Ben.

      This replaces the tube that connects the two carbs on a 1987 Honda XR600R (it may fit other years). 
      Made in the USA. 
      Constructed of TPU  (solvent safe plastic.)
       Its durable stiff abrasion resistant yet flexible enough you never have to worry about breaking it when you're taking apart your carbs. 
      Fits the o-ring perfectly and slips into the carb nice and tight.
      Matches the rear shock coil. 
      If you would like to buy one contact me via e-mail. They cost $20 Shipping is free (anywhere in the USA). $10 off for active duty or retired military.
