Head replacement/Valve Tune 1981 XJ550

Ok, I had to put a different head on my bike d/t a couple broken exhaust bolts...Happy to say, new head is on, timing chain and cams are also back on and in spec. Now on to tuning the valves...

Intake:
1 - .13 245
2- .1 245
3 - .18. 250
4 - .18 260

Exhaust:
1 - .15 260
2 - .15 255
3 - .04 255
4 - .1 255

I read on some thread there was a trade system going on. I am willing to donate my extra valve shims to the group. Otherwise would love help on where to obtain the correct sizes.

Thanks!!

Intake:
1 - .13 245 good
2- .1 245 need 240 swap 245 into exhaust #4
3 - .18. 250 need 255 swap 250 into exhaust #2
4 - .18 260 need 265

Exhaust:
1 - .15 260 need 255
2 - .15 255 need 250
3 - .04 255 need 240 swap 255 into intake #3
4 - .1 255 need 245 swap 255 into exhaust #1


need a 240 for ex #3
need a 240 for in #2
need 265 for in #4

so you need 3 shims to do the job

 

Everybody loves the "shim hop" !!!!

Just make sure you do them one at a time, and don't turn the engine without a shim in place.
