Topic: 2nd gear feels like it's not getting gas at high rpms

When you say "rebuild" what exactly do you mean by this, did you just do an engine rebuild?

[goldarrow]

Oil leaking could be from badly leaking shifter seal, but wouldn't know for sure until open up the shifter cover

I left the engine alone. I completely stripped bike to frame and rebuilt it.

I'm going to go work on it for a bit tonight and see what I can discover. Thanks for the tip goldarrow! I swear I didn't touch anything this time

K. Shifter cover off. There was a tablespoon- ish of oil in there, but no obvious leak. If it was the shifter seal,  would it be actively weeping even with the oil cold?

Shifter seal is available from Honda about $4 I think

Well. I think I figured this out, but I have to ride it tomorrow to make sure. This may sound silly, but:

I think all the oil that dumped out my shifter cover was oil leftover from my accident that spilled out the engine breather back in August. Im not sure how it managed to stay in there all this time,  but I checked my oil level,  and it's reading full. I can't find a leak despite cleaning up all this oil. I lost a lot of oil out the breather tube when I went down, some of it probably found it's way inside the shifter cover and spilled out given the angle of my driveway.

At worst it's the shifter seal,  at best it's my above guess. What a wierd thing to happen.

Regardless,  ill update tomorrow

[Redline it]

I think you might be right. This morning I had a really hard time kicking her over. Sparks firing, gas flowing to bowls, compression is fine. My guess is the floats are set wrong and it's having a hard time sucking anything up. Once I kicked it over I had no problem kicking it over again, but getting that initial grab was like pulling teeth.

If the bowls were low I would expect a definite stumble not just feeling of being low on power.

~5,500 to ~8,500 is the sweet spot for producing power...how high are you revving it? The power does drop off when approaching redline. When I get on it hard second gear runs out real quick and reach for third.

It does not sound like a transmission problem.

Cheers,
Kenzo

Yea it is definitely a gas problem. Although it hasn't happened in the last few rides, so I'm waiting it out to see if it resurfaces. Essentially I'd hit anywhere above 4,500 in 2nd and the engine would stumble really hard (exact same feeling like if you've ever run out of gas on the bike or even in a car), burping, choking, coughing, whatever you want to call it. Then I'd shift into 3rd and perfectly fine. If it starts happening again I will report back.

Also, rode the bike into work today, ~20ish minutes, no oil came off it. I only briefly looked under the bike when I parked it to see if there was anything weeping (or pouring) out from under the shifter cover, nothing. Fingers crossed that my guess was right.
