seems to happen most shifting from 3-4 under load it wont shift..

i was having shifting problems, couldnt find neutral, slipping etc...

long story short, my clutch was toasted, got a new clutch installed, put the stock shifter back on and its night and day now, feels great, find neutral SOOOO easy now, only problem now is shiting from 3-4 4-5 under load..

 

my bike is not a huge hp bike at all..

Sounds to me like you might have a shift fork bent, I'm not sure what forks work what gears, but I'm pretty sure the left rear fork works your 3 to 4 gears, and maybe even your 4 to 5 gears.

where are the shift forks, do the cases need to be split to change the forks?

yes they have to be split.

 

so it wont shift at all? or do you have to let all the way off the gas first?

loco i have to let off the gas and then it will shift fine.. everything else is smooth, down shifting, finding neutral etc..

maybe you need to pull your clutch cover and check this thing... its the adjuster for your shift shaft. it could be adjusted wrong. by the sounds of it, easy downshifting but problems upshifting..

 

the other thing is that maybe you have more power than you think and its just hard to shift up like 4mm and big motors.

 

heres that adjuster. i think you should check it before tearing the cases apart.

thanks for the pics, how do i adjust it properly?

i was told that my bike had high 60's low 70's hp, but i guess more like low 60's but anyway i guess ill have to check that out.

you will have to bend the lock tab back on that nut and adjust the eccentric

screw with a flathead screw driver. pay attention to where the shifter is riding

on the shift star. you want to center the shifter between the pins on the shift

star as close as you can. tighten the nut and bend the lock tab back.

clear as mud? lol

 

sorry im late, you probably have this thing fixed by now.

Ever figure this one out? Im having the exact same problems. Put a new clutch and a lockout in it and it wont shift 3-4 4-5 5-6 under a load but it rides fun just cruising

not tryin to jack the thread. but.... i am having some trouble with my shifting also. i have a 421 cub with lockout straight cut gears and it is very hard to down shift when the bike is running. and when i have clutch pulled in in first just idling it still wants to move... andn it was hard to shift up when i was tryin to get on it. but i figured it had something to do with the same reason urs isnt shifting to so i thought i would ask sorry bout jacking i just gotta know man. thanks. cause i just got the bike yesterday.

I would like to say that with everything new and adjusted right this is what a Banshee does. When putting out 60 or more HP with HD springs installed it will not shift at WOT. I get calls and email on this all day long. You have to run stock springs or HD springs and:

Cut shift star

and or

Shift shaft mod (FAST)

or

override trans

If you run my port job this is what you will have to do. Sometimes you can get away with half HD springs and half stock springs and it will shift under load. Not all people have this problem. If you don't shift under load at WOT and don't have 60 or more HP it wont be a problem.

ill grind the star myself, but what does FAST do to the shaft exactly?
