I have a 98 HD softail with a 5 speed EVO. It seems to be having trans issues. It fill grab for a split second in 5th gear and 5th gear only. It will happen about every 5 to 10 seconds. I can feel it...
Well, I've have heard of this problem before but I've never seen it for myself. I wrote a opinion here just the other day concerning this problem in a 1990 bike.
This is unusual. I'm afraid that if your transmission is doing this, you are going to have to do at least a partial teardown of the transmission.
I could be that the shifter cam is not rotating fully to put the 5th gear clutch dog into gear. This would cause just the tips of the lugs to be driving the final drive gear. And, it could jump out and back in from time to time.
Now, why the shifter cam is not rotating fully is the question. If the rest of the gears seem to be shifting fine, I wouldn't think it was the shifter pawl but it could be.
If it were mine, I'd remove the exhaust system and whatever else needed to gain good access to the the transmission top cover. Remove the cover and raise the rear of the bike off the ground. Now, you can shift the transmission and watch the actions of the shifter cam. Pay particular attention to the 5th gear shifter fork. See how much "play" the fork has once it's shifted into gear. You may spot something wrong there and be able to repair the problem without pulling the transmission out of the frame. If not, you may have to pull the entire transmission or at least the trap doors with the shafts to inspect the final drive gear. You may wind up replacing the final drive gear if the clutch dog has been jumping in and out of gear.
One other thing. Have you checked your front belt pulley? I've seen the splines in the pulleys wear to the point that they just strip out and won't pull the bike in any gear. Check that before you start tearing down the transmission. Usually when this happens, (excessive wear on the front pulley) it is accompanied by a small transmission fluid leak. If you ride the bike and park it, it'll leak a spot about the size of silver dollar. If you wipe the spot up, it won't leak again until you either ride the bike again or start it up. Then, it'll leak again. The transmission fluid is leaking past the "quad seal" behind the pulley.
