3AJ clutch issue maybe??

Hi Doubleyoupee....so you have been for a ride on the bike? Presume you have couple mm freeplay at clutch lever freeplay?

Hi dzl, yes, i've been for a ride. All seems well, it shifts perfectly, but clutch slips in 3rd 4th 5th gear full throttle, and is hard to get into neutral.

I would re check the adjust screw for clutch push rod and yes back it off 1/4 turn to allow for expansion when engine gets hot.

Hm...Weird thing is if I back it off 1/4 there is still tention on the push rod. If I turn it it in until I feel resistance and then back it off 1/4, the push rod arrow is not aligned with the crankcase marking as per manual.

Do you have the correct clutch perch and lever? I have had an aftermarket clutch lever that didnt allow the cable to pull as much as it should do, causing clutch to not fully disengage and causing clunking/ hard shifting. Replaced clutch lever with OEM which had different bend, allowing more cable pull and fixed it. Did you check your clutch spring length also before installing and are within spec?

It's stock. Regardless, I checked the free play at the engine side. The cable is a bit lose in the cable holder so there is definitely free play on the cable.

Something I have also come across that caused difficult operation of gear lever after engine rebuild, is if the mounting bolt for the stopper lever for the shift drum has been over tightened. If it has it will cause the stopper lever to bind and cause stiff gear lever operation and gets even stiffer the hotter the engine gets. Needs to be torqued correctly to 10nm only.

I put the torqued all engine bolts including this one to spec with torque wrench. It shifts fine otherwise.

Thanks

Did you install the clutch plates in the right order? You probably noticed there are two part numbers for the 3aj clutch that are different dimensions. If you put them in in the wrong order you can cause hard shifting and clutch slippage.

Geoff in a previous post on a different topic said this:

“one goes in 2nd (to accommodate the wave plate) and the other goes in last..... do not try to use your bike with both large plates in first.”

Yes, according to the manual.

I think/hope I simply installed the wrong set of clutch plates. I'll ride some more and then open it up. Wanted to do a quick 2nd oil change after rebuild anyway!

So opened it up this weekend.
Didn't forget the small ball
Pushrod setup seemed OK too.

So I replaced the clutch plates with the other (used) set. They looked the same and have the same width.
However, no more clutch slip .

Only fuel pump left and it's ready!
