Help, wont shift gears


Recommended Posts

My Banshee wont shift out of 4th and 5th gears. The oil looks grey and shinny. I took my banshee for a ride for the first time this winter, it was cold out so shee ran quit lean. After letting it sit for a half hour after the first ride, I noticed it was smoking more than usual when I stared it up again. After letting it warm up I tried to ride it again, but noticed it would only shift from 4th to 5th but is stiff trying to shift. ( does anyone know what is causeing this problem, and what I need to do to fix it ) Any help would be apreciated, thanks!

I would bed 8571895685784712 dollars the you need an imput shaft and 5th gear. If they are run low on oil and/or revved high while not moving will cause 5th gear to lock up on it. It runs on just the shaft there is nothing under it like the runners on the rest of the shaft.

Ok, I finally have some spare time to work on me banshee, I have been to busy building my house the last year, and had on time for her, now I miss her! So far I have my engine pulled out, and have it tore down to the case, I need a puller for the magneto fist before I can split it open.

I was wondering is there anything else I need to know about before I split the case? I have never done this before. I haven't found any problems yet, so it is probably the shift forks caseing the shifting problem. Are they hard to change once I get in there, and should I change anythig else while I have it split open. I was thinking I should change all the seals, and put a moded shift star on it to help it shif smoother. I can never find nuetral with my foot either, will the shift star help with that as well?

Thanks for any info guys! :confused:

I had the same problem. I would rev it to the sky to launch in the 1/4 and the tranny got stuck in 4th and 5th. What do you guys recommend. Is it just easier to buy a complete tranny gear assembly? I tore the cases apart but nothing seems bad. I had to kinda unlock the tranyy for it to spin freely again, and now it shifts through the gears but still fells a bit ruff.

Can you elaborate on this. Any pics or schems?

had same trouble in 2nd/3rd gear a few years ago on my 2000. changed out the shift forks and shaft-And the problem went away. while your in there check all the bearings (crank/tranny/rod)-no sense in putting a case/motor back together w/ worn out parts.

which shaft did you change? The long shift shaft?

while your into the tranny you want to inspect all the dogs on the gears for signs of wear (tabs that lock into each other), the shift forks ( for signs of scuffing of discoloration of the forks as well as the gears where the forks ride and the shafts that the forks ride on) and remove all the gears so you can inspect the shafts for ridges (after many hours the shafts in the tranny can develop ridges keeping the gears from sliding back and forth correctly) basicly your looking for any signs of wear that might cause a gear to slip out or anything that might cause a gear to keep from engaging...

Ok, I split the case and checked everything out, I don't see any problems with anything. All the gears move on the shaft like they should, the shift forks and the shafts look strait. Do you think I should change the shift forks anyway, I don't want to spend much if I don't have to? Is there anything else it might be? I just got my Clymer manual in the mail yesterday, so it should help me put my engine back together at least.

my experiance with shift forks is that if they show any signs of wear then they should be replaced. usualy you find that if they show signs of wear it's usualy uneven because they are getting sloppy where they run on the rods. basicly if they look pristine with no signs of wear then dont bother replacing them.

if they do show signs of wear then you need to look closely to figure out exactly whats wrong with them...

 

if the tips still look silver but have polished spots that are higher one one side than the other then the forks are wobbeling back and forth on the rods. if the tips look discolored (any color than silver) then they need replaced and you should look at the gears they ride in for wear also....
