Last summer I posted about a problem I was having. I mis-diagnosed it a bit but was corrected by anther forum member.
So the problem is that in any gear, it seems like I hit a
rev limit and the engine flubs out. It's about halfway to 3/4 of the way through the rpm's, If I get their
gently, I hit the limit and it starts to go. I can feel the engine firing as it lurches forward, then I can feel it kick out as it slows a bit, rinse, repeat. If I just
crank the throttle, it just flubs. It does not stall since as soon as it gets back to halfway through the rpm's, I get my power back. The speed is not an issue as this can happen in any gear.
SO. I had a LONG list of electrical issues to sort through from forum members. I THOUGHT I had fixed it with a bad connection at the ammeter. Not the case. Took the bike out from winter storage, gave the electrics a once over, and the problem persists.
Before I get long winded, I'm wondering if the problem could be in the carburetor. I have a 30mm flat-slide with a wide open exhaust. The bike ran rich when I purchased it so I leaned it out a bit with the air screw. Could the problem be any of the following:
-Too much fuel getting in?
-Too much air getting in?
-Float bowl overfilled?
I have not tried draining the float. I have no prior carb experience. I'm wondering if I just need to fiddle with the air screw a bit. Or adjust the float.
Let me know if anyone things this COULD or COULD NOT be the culprit. My bike is still not under my roof but I'll be working on it this weekend. I'd just like to know if any of what I'm guessing could be an area to investigate.
As always, thanks in advance for any help you can give me.
