It's probably going out the breather into the carb.
Stomping on the shifter is a surefire way to make your bike shift even harder if you manage to bend the shifter forks inside the engine. Shifting hard is often due to a dragging clutch.

A dragging clutch can be caused by a few things, the most common being the cable is out of adjustment. Warped clutch plates and/or a notched clutch basket, or a frayed clutch cable are other possible reasons.

ok cool, thanks, i wasn't sure what the term meant. at this point i don't think there is any internal damage. changed the oil to 20w50 then took her for a ride, she seems much happier. i think the issue might be heat related it has been really really hot and rainy here the last few weeks and it seems on those days is when it happens. i was running the normal 10w40. all of my riding is urban at the moment and mostly commuting. it seems to happen in stop and go traffic on streets. on highways she seems fine. back and forth to work is all streets. which is about 90% of my riding.

i think it may also be time to lube the clutch cable. come to think of it all the cable probably could use a good lubing.

thanks every one.

A dragging clutch just means it is not fully released when the lever is pulled all the way in. The bike still wants to drive forward a little. As noted, it can be caused by a number of things.

I know this an older thread, but I was looking for the answer to a balky shifter. The solutions here did not help. Soooo..... it's a training bike with 2900 miles. Don't remember the year, but it's white pearl with the flames on it, so it's a later model. I figured if I can't use it, may as well dive in to see what the issue is. I can sell it, junk it, etc. I have one on the second lift that is being parted out and am using it to compare.

Drained the oil, took the cover off. Cover popped right off and clutch lock nut was not properly staked. Evidence that someone had been here before. Checked the star wheel that selects gear - everything looked fine. Bike would hang between gears when not running and not shift at all when warm. Kept comparing. Took clutch off. Still good. Removed star wheel and shifter shaft. Turned shift drum by hand. Would occasionally hang, but I figure most bikes will when they aren't running. Turned mainshaft (the one the cltuch is on). Bike will drop into gear - sometimes requiring a jiggle or more turn of mainshaft. Looked up in the case where you can see gears and shifting going on. Everything looked okay - could see things moving and they felt pretty smooth.

Studied manual and other bike. Checked to see if there was play in mainshaft - AH HA! Seemed to be a LOT of end play. Compared with other bike, which does not have very much end play. So put it all back together short of clutch and messed with shifting a lot. Found that when the bike was hanging between gears was when the mainshaft was moving to the outer limit of the end play. And looking at the star wheel, can see that it is hanging up between gears.

Played with it some more. I feel confident that the end play is the cause of the sticking shifter on this bike. When the shaft moves OUT, the shifter hangs.

The oil had been changed, the cable was properly adjusted. Sooo.... this one will probably get a motor swap - splitting the cases is beyond the scope of our repairs here. And I got extra motors...

SO if nothing else helps, you may have to look deeper into the problem. Be sure to check that end play - could be the culprit.

I figured this is as good a place as any to post this. When you google "rebel hard shifting" this is the first link that comes up.

Ok I'm posting in this old thread instead of starting a new one.

I'm having the same hard shifting issues, once warmed up I'm having shift issues in all 5 gears. To the point if I ride in tennisshoes I can not shift I have to put on my steel toes to shift the bike once warm. Cold I can shift every gear without the clutch or letting off the throttle.

I was thinking it was an oil issue like weight till I read this. To get started I'll try to adjust the clutch but I dont know where it should be adjusted too? It's got the proper free play and the bike does not pull at all sitting at a red light. The fact that it's so easy to shift clutchless when cold makes me think other than clutch adjustment but I'll start there if someone can tell em what I need to do?

Thank you

Michael

The only adjustment is via the cable. If you have the proper lever freeplay (3/8-3/4") it has to be something else.

Keepin' all the left over parts. Gonna use 'em to build another bike!

As I read this thread, I began to wonder about oil issues too. But my thinking was exact opposite of everyone else that posted here. They seemed to want to go to a higher viscosity (thicker) oil. I was thinking they should try a lower viscosity oil.

The shifting problems described occurred when the engine was hot, and went away with a cold engine. My thinking was the multi-weight oils being used were getting thicker when hot, and causing too much shifting drag. (When cold, the multi-weight oils are thinner.)

The Honda owners manual for my 2016 Rebel 250 calls for 10-30 oil. It makes no allowance for other weights, regardless of ambient temps. I wonder if using a -40 or -50 weight oil in hot weather might be causing too much friction/drag for some Rebels that are a little more finicky in the shifting department?

Ok so that was my thought it cant be the adjustment making it this difficult to shift I rode it again to get oil from cycle gear and when I got to cycle gear which isnt gar but the bike was up to temp alreadywhen I left. I could not down shift the bike, when I got there and was parking it was flat stuck in 4th gear I had all my weight on the shifter with the bike rolling but no downshift. While .ik was in cycle gear it cooled down I guess enough that I walked out it popped right down to 1st and shifted fine till I was almost home. So I changed the oil (which looked brand new as it should since it has 250 miles on it) thinking maybe it's the wrong weight.

While the oil was draining for ****s and giggles I pulled the spark plugs both are white and chalky like the engine is extremely lean.

This is a ca bike for the record

When I was putting the oil drain plug back in I noticed the end of the head pipe, I think where the double wall ends, and the first 1/4 inch of muffler body are blued pretty bad. Could this go back to what I was just talking to you about and theres junk in the carb and it's just getting to hot? For even the trans but not seizing?


Riding home from cycle gear the shifter was actually hanging up, try to upshift and it would stay up till I pushed it down but then after the oil change it would fall back to the neutral position again.

Thank you for your help flitecontrol, I hope I dont annoy you to much
