za50 clutch flip

i know this is the wrong forum but i'm not getting much response from performance tuning.

I've rebuilt my za50 5 or 6 times over the past two days and when i finish, the bike starts up great and then revs really high when i open the throttle but the back wheel hardly spins at all.

I've tried flipping the second gear clutch but now I put everything back the way it was before I changed anything and it still doesnt work! Just revs high and doesn't go. its not engaging.

in DESPERATE need of some help here

thanks

mike

no worries, happens once a month.

Re: za50 clutch flip

perfect timing! Just ripped open my za50 to replace the pucks and decided to check the forums and didnt know anything about this.

thank you cuperteenbro! Many internets to you!

Re: za50 clutch flip

Yes, i just got my Magnum and I am replacing clutch corks.

Re: za50 clutch flip

also make sure that the screw on the 1st gear clutch is on GOOD and that the lock washer is bent up TIGHT. That nut came loose when i was riding and locked up the back wheel. Now I reassembled everything and there is a grinding noise when i turn over the engine to start it. Any ideas? I know...it could be a lot of things.

Gonna be cracking it open again tomorrow. I should have just left everything the way it was. I went to replace the pucks and they were in perfect condition. Replaced them anyway and flipped the clutch. hopefully i can get this grinding under control

torque your nuts and use the lock washers... c'mon now, the 24mm deepwell socket isn't that rare. the grinding is coming from somthing that spins :p take it apart completely including the starter plate, look for metal bits and unusual wear and put it together again.

Re: za50 clutch flip

Look at your gears and make sure nothing got sheared off.

Re: za50 clutch flip

I know this is super old but the OP post is what is happening to me RIGHT NOW. and that image does not load anymore. Someone please tell me why it's just revving out with no movement anymore. 2nd is flipped.

Glad you did. What was the issue?

It was either the roller bearings or a shim issue/possibly not tightening the two bolts all the way. I consulted many pictures and Alex from DMW. I thought we had put the bearings in correctly the first time but we pulled them out and made sure. Slapped everything back together and she started ripping. I also used ATF type F the second time instead of 10w-30.

Re: za50 clutch flip

Thanks. Just wanted to know in case it ever happens to me. So far so good!

Re: za50 clutch flip

It is almost ALWAYS the roller bearings. They are very easy to install on the wrong side of the flap. This will allow your bike to run and rev but won't send power to the back wheels.

You know you installed the bearings wrong if it was easy to put them back in.

I bought a Magnum cheap with this issue. Looking at a not too aggressive kit now. Good to hear this problem was solved.
