The grinding approach is a backup. I'm glad you didn't have to resort to that
A note on jetting. I started the bike yesterday in freezing weather. It barely needed a momentary choke. Stalled, and then it started without choke, bone cold. I think I am a bit rich on the pilot jet.
The other think it did was it started to drift up to a high idle. I am pretty sure this same behavior happened to someone else recently. I thought maybe it was leaning out from a intake spigot leak (the rubber connector between the carb and head). But this really makes no sense since it didn't even need choke to start at 32 degrees cold!
I put the bike back under the tarp. Too cold to ride. This doesn't affect performance, but I would sure like to know what is causing this  |
Mine would idle high sometimes, as well-and occasionally stall. I didn't ride mine for about 4 days last week, and I pulled it out of the garage. It started, died, and wouldn't start again. I've only run non-eth in it, so I know it didn't clog up with corn syrup.
Checked fuel filter and flow, checked for spark-good. New NGK plug for a laugh. Nothing. So I did what all real men do, and pulled the boot...and blasted it with starting fluid. Started, ran out of laughing gas, and died. I could likely figure this carb out, but I don't have the patience right now. I'm in the middle of a street tracker build, so I'm looking for my other bikes to be runners. I ordered a Nibbi PE28 for it, and I'll give it a shot. If that fails, I'll get a real PE28. They're really not expensive, and I know they work. Some of the Chinese carbs are a real crapshoot.
I used to commute on a 2012 CCW Misfit. It was 5 years old with 9k miles when I bought it. Aside from a clogged emission mess once, it was dead reliable. I fixed all of that,and cleaned/rebuilt/rejetted the carb. It ran great. I sold it to a friend of my wife who's my age three years ago (I'm 52 now) who always wanted to learn how to ride. I clean the carb for her at the beginning of every spring, because she doesn't understand that "premium" doesn't mean non-eth. Literally emptied syrup out of it this year. Carb cleaner, compressed air...BOOM! Runs great. Carb looks like absolute cheap trash, but the bike always runs fantastic (when clean!!)
Might buy the bike back just for the carb.
