I've had my 71 CB450 running and on the road for about 3 weeks now and could never seem to get it running perfectly. I've been tinkering with the timing and got it to run the best I can but got tired of the popping coming out the right exhaust and lack of power. A buddy of mine just did an intake and exhaust and power commander on is Grom and he's leaving me...... Just embarrassing, I know.
When I took the timing plate off the points and the stater cover off I began turning the engine over by wrench just to see when my spark was STARTING to hit. It hits about mid way through the compression stroke. I sat for about an hour trying to adjust and flip the advanced timing gear for craps and giggles, but nothing I can do at the points will let it FIRE when it's supposed to. The lobe starts OPENING the points at the point where I should be CLOSING the points. Like an idiot I forgot to snap a few pics of the points and advanced gear, but I do have my timing marks.
LT on my Stater: (dead on)
Timing Mark Exhaust Cam: (mark on the cam is slightly over the mark on the block)
Timing Mark Intake Cam: (mark on the cam is slightly under the mark on the block)
NOTE***** The advanced timing unit looks to be good. The marks all line up and I'm 100% sure it isn't 180* out.
If anyone can help, I would greatly appreciate it. Are you able to set timing without pulling the engine? Also, you're supposed to check timing at LTD at the end of your exhaust stroke and before the intake stroke correct?
