its as simple as this. the timing on the right cylinder seems impossible to get right on the money. the left cylinder i got right on. i pulled the plug on the right cyl. and the sleeve in the jug is all black. (not shiney and clean like it should be). i thought rings right away??? any other ideas??
 
timing-plugs-rings????

OK

start with the basics....you do have a FACTORY manual for the bike right?
what are the compression numbers?
points gapped right?
staticly timed right?
you sure the coils are good?
valves are adjusted?
carbs clean?
petcock primed?
carb diaphragms in good shape?
do you think its only running on one cylinder at idle or at higher RPM?

factory manual: check
comp. test: next on the list
points are gapped: check
staticly timed right: i got the left cyl. right on. but the right i cant seem to get no matter what i do.
coils: no idea
carbs are spotless and diaphrams are good
havnt looked into adjusting the valves.
I never knew i had to prime the petcock??
and the motor smooths out at high r's it likes to back fire on the right cyl at idle. and it bogs out when you hit the throttle from idle
 
I honestly dont understand why you cant get one side timed statically. I is a matter of lining up the mark and gaping the points. so i think we are talking about different things.

re read the points section of the manual and go through it

trust me it really threw me for a loop too. the points are clean and gaped between .12 and .16. i first tested with a volt-meter and manualy rotating the motor. that approach worked out good. so then i go to the timing light and they are both close but not spot on so i start turning the back plate a little at a time and i got the left cyl. to hit right on but the right cyl. fires at the "T" and not the "F" and there is no more adjustment left on the back plate???
 
One set of points usually moves relative to the plate and the other set are fixed. Set the timing on the fixed set first and then the movable set.

Sometimes there's not enough adjustment so split the difference by closing the points up a thou or two on the one that's advanced and open up the set that are retarded.
 
i was gaping the points first then checking with the voltmeter then doing a static test and turning the plate.
i did a comp. test. right cyl. 170 psi. left cyl. 160 psi. (note this was cold, not at normal running temp)
i also checked the valve clearance the right cyl. had a ever so slight adj. on the exhaust and thats it. ill have more to come on adjusting the gaps like "teazer" said to try.
 
Did you have the pionts advance apart cause the point cam will fit both ways that fixed a 350 that i bought (po had apart and could not get running) even then the rear point was a fucker
