banshee shift issue

[chads300]

I acquired a 1987 banshee a couple months ago and work picked up so its been setting in the corner...has basic bolt ons  like exhaust filter, nerfs  ect. well I am ready to start figuring out what the problem is.... the bike wont shift at all if you try and shift it normally but: if you put pressure on the shifter(push shifter in towards motor to get pressure on it) it will shift perfectly fine. any ideas would be great

These transmissions are fairly simple. I would start by pulling the side cover and looking at ur star, shaft and eccentric adjustment screw. If all that is good could be a shift fork maybe worn?

It's probably one of those things listed above inside the clutch cover, but first check that the shift lever is tight to the shaft and has good splines.

splines are good shifter is tight.....the idiot I got it from was going to use it as a "parts" bike for his other banshee........upon looking at the quad I spotted the reason why it would not star(disconnect choke crossover tube) so I bought it for $850. I should've worded it better in my first post if you play around with it it will sometimes shift but if you put pressure on the shifter it will shift perfectly threw all 6 gears

I would look first at the eccentric screw and the spring that rides on it then.

ok what should I be on the lookout for? and btw the purple n yellow bike in your pic is hands down one of my favorites sorry just had to share that haha

Thanks, look for wear grooves in both. Also for wobble in the shift shaft claw pivot. The shaft shouldn't move when you put pressure on it. If it does the shaft could be worn and the white bushing that holds it from sliding to the left, the cover has a bung on it that holds it from sliding to the right. All things to look at.

ok so more than likely I should have to split the cases?

[hoppedupandcutdown]

No need to split cases, all that is behind the clutch cover. Nothing that you put pressure on by holding the lever "in" touches the forks.

Get a Clymers manual for a Banshee, money very well spent.

good point thanks for the advice,

Probably shift shaft , eccentric replacement would fix it. Total cost maybe $35. These guys are steering you right on.

You can also take a piece of straight stock, about 1" by 6" and drill two holes in it corresponding to the two lower left screws in the side cover, then when the cover is off, bolt that piece on to mimic the spot on the side cover that usually hold the shift shaft in. That way you can shift it and see what is going on. Not running of course, and will need to be spinning the back tires.

ok I will give it a try tomorrow after I get this dam predator done thanks for all the help

Shift shaft bushing, eccentric screw.
