FASTOYS Posted February 12, 2006 Report Share Posted February 12, 2006 Some things to look at : shift drum corners rounded off (where the forks ride), shift forks bent of burnt looking, shift shaft out of adjustment, bad clutch components !!!!

mattmill29 Posted February 12, 2006 Report Share Posted February 12, 2006 Some things to look at : shift drum corners rounded off (where the forks ride), shift forks bent of burnt looking, shift shaft out of adjustment, bad clutch components !!!! 472169[/snapback] Speaking of bad clutch components(my bike has the same problem, won't shift) My cluth basket has five notches etched in each finger, more so on one side of each. The book makes no metion of this. Would these notches affect the action of the clutch? Quote Link to comment Share on other sites More sharing options...
dajogejr Posted February 12, 2006 Report Share Posted February 12, 2006 ABSOLUTELY.... You can prolong this a little IF the grooves aren't too bad, get some scotch brite pad on angle grinder...and grind 'em smooth. Again, IF the notches arent' too bad. If they're pretty rough....get a new Hinson basket....or other comparible aftermarket basket. Time to check out the rest of your clutch, too. it's only grooved on one side of the "ears" because that's where all the pressure goes to...

blueshee03 Posted February 12, 2006 Report Share Posted February 12, 2006 try a new shift shaft and a new adjusting eccentric.also check the shafts that the shift forks slide on,they may be worn or bent a little.make sure they are round and not worn oval shaped.

aggies52 Posted February 12, 2006 Author Report Share Posted February 12, 2006 is their any kind of alignment with the gears in the trans? should i be able to get through all the gears without the clutch? before i put the shift shaft and shifter in it seems to go alright if i move the sprocket back and fourth, when i install the shaft it seems to get stuck in 3rd or somethin like that... it just stopped workin one day ridin.. we take it apart, clean all the shit and put it back in shiftin fine, realize i forgot the circlips in the shaft.. and go back together and it wont shift.. it shifts but like it just gets hung up.. does the shift cam wear out? after a period of time does somethin wear out to loook. i see no metal shavings, and no broken parts.. shift forks seem to be not seized, forks arnt burn and not grinded up at all.. wtf could this be? would a new shift star and cam solve this, performance ones? PS it shifts fine with just the forks and cam in there.. when i put the main shaft and counter shaft in it gets messed up... but the whole time i didnt have the clutch on.. will it not shift through all gears without the clutch on... kinda weird cuz it shifts fine with just forks and shafts for forks... like i said when i put the trans gears in it doesnt work... checked the book they are put in right???????????????

dennybyz Posted February 14, 2006 Report Share Posted February 14, 2006 ive seen the main shft that does the shiffting go bad the forks look good but it wont shift this is caused by power shifting very fun but does alot of damage to yhis particular part pluse this part is only 39 bucks .....another thing you could look at is the cam that goes down into the motor ...your cable hooks to it and check to see the ball bearing is moving freely ....ive actually got clutch so hot i welded it to long rod that moves out clucth boss....what your looking at does not have to look bad to naked i to be bad .....spec it out Quote Link to comment Share on other sites More sharing options...
BigRed350x Posted February 14, 2006 Report Share Posted February 14, 2006 I remember with my 87 when I had the cases split i could not get it to shift for the life of me. I smashed on the lever with a sledge hammer and it wouldn't budge. Everything measured up to spec, and I had new forks and the bars they ride on. I got all made and said screw it and put it back together and it shifted fine once i had the cases bolted back together. No idea what it was. Worked fine for about a year after that before I sold it. Maybe they just need to be suspended in the oil to work good. Banshee Trans are just stiff to begin with though. The shift star mod helps a lot with that. The RZ transmission is supposed to be a little more smooth, you might consider that. They have a little different ratios too, some people like them more. I've never ridden one though, so I can't really tell you about them. Quote Link to comment Share on other sites More sharing options...
Fastrat Posted February 15, 2006 Report Share Posted February 15, 2006 The fingers worn into the clutch basket are from the clutch plates wearing into it. This usually causes a bike that will want to creep even when the clutch is pulled in. I've never known of this to cause an inability to shift, though. Maybe in an extreme case it won't disengage the engine from the tranny and acts like shifting under full power. Easy fix for this, use a flat file and file it smooth. I don't recommend a dremel, it's too easy to take off too much material. All you want to do is make it smooth so that when the clutch is actuated, the plates can freely float and disengage the engine from the tranny. So don't take too much off. Also look at the inner hub the steel plates ride on, chances are the same thing is going on there. Quote Link to comment Share on other sites More sharing options...
lastlegwarrior Posted February 15, 2006 Report Share Posted February 15, 2006 something you might check for is a burr or scuff on gear shafts (not sure of the proper term, but the shaft he gears are on) The same thing happened to me about two years ago and it would not let me shift between 2nd and 3rd. took it all apart and couldn't find anything wrong with it everything checked out fine, nothing bent or misfigured. then i noticed a burr of some sort on the end of the gear shaft that was preventing the gears from sliding smoothly along the shaft. Filed it down a bit and it has been shifting smooth every since. Just my 2 cents, hope it helps. Quote Link to comment Share on other sites More sharing options...
badassbanshee479 Posted February 15, 2006 Report Share Posted February 15, 2006 I had ths problem after I put my cub motor rogether, went through and replaced cam shift forks, inner and outer clutch hub, new hinson basket, and a moded shift shaft form FAST racing and my tranny has not shifted like it does now since I have owned the bike. the way I figured it was, it may have been a bonch of little things adding up to make a big problem so I eliminated them all, problem solved. oh and if you are trying to bench shift the bike the shafts have to be spinning the same direction the would be if the bike was running and they have to be spinning pretty fast so you may not be able to get it to shift right till ya get the bike goin again.

MDS2106 Posted February 15, 2006 Report Share Posted February 15, 2006 Wear in the clutch gear cushions can also cause shifting problems. Quote Link to comment Share on other sites More sharing options...
