Happy New Year!

Looking back on 2017,  you probably put a healthy number of miles on your Z1 or you finally scored a CB750 after hours of scrolling through Craigslist. In both cases, a carb cleaning/rebuild may be in your near future.

  • Is your motorcycle hard to start?
  • Is it running a bit off-kilter?
  • When you dial the throttle, are you getting the desired performance?
  • Do you ride with the choke on? ( this means you have a clogged pilot jet )
  • Sluggish acceleration?
  • Bad fuel economy?

These are all signs that your bike is in need of some carburetor love. In most scenarios, there’s only really one way to see if your carbs are due for a complete rebuild: pull them off the bike and take a look inside. And since you have them off and dissembled, you might as well do your future self a favor and rebuild them now.

January’s Featured Products are dedicated to those precious carburetors, everything from the entire assembly to the needle and seat.
