Reed Valve Removal:
|(Click To Enlarge)|
|Remove the carburetor boot mounting bolts, then pull the reed valve assembly and gasket.|
|Make sure to stuff a shop towel in the reed valve housing to keep junk out of your crankcase.|
Clean & Inspect Reed Valve Assembly:
|Clean the reed valve housing inside and out with a PLASTIC scraper.|
|Inspect the reeds for any visible damage. If you find any, replace your reeds. |
Inspect the reed valve body and reed stoppers.
|If you find a missing screw, you might want to check out your crankcase.|
|If your reeds look good, use your feeler gauge to measure the clearance between the reed ends and the body.|
|These valves are within spec, but since I don’t know when they were serviced last, I am going to install a set of new pedals.|
|Remove the reed stopper mounting screws, discard the old pedals, and clean the body.|
|Align your new pedals, and install the screws with thread locker.|
I find it easier to thread the screws a few turns, then pull each one out individually to apply thread locker.
|Make sure the thread locker does not get on the pedals.|
Reed Valve Installation:
|Remove the shop towel from the reed valve housing, and install the new reed valve gasket, with the tacky side in.|
|Install the reed valve assembly with the tabbed side facing up.|
|Make sure the clutch guide is mounted on the top left side of the assembly.|
|Install the mounting bolts finger tight, then gradually tighten them in a criss-cross pattern.|
