PLEASE help if you can. 1st gear problem
« on: April 05, 2008, 07:36:58 PM »
I have a 1972 cb750. Before I resore this bike, I have 1 issue I need to clear up. Right now the bike starts but doesn't run that great. The problem I am having is with what I think is 1st gear. I have to get a running start (with engine idling) to ride it because I think it isn't in 1st gear (feels like second). When I push the shifter down all the way it seems like it is "clicking" into first but seems like Im in second. And because the bike is running a little rough, I can't get the RPM's up enough to take off (because I believe it is in second). But don't forget, it is clicking and feels like it is in first. Could it be a clutch issue? Once on the road, I shifts fine through the gears. Once I stop and try to take off again, Same thing. The bike has only 8,000 miles on it. Oil is full... All the obvious is ok.... Any suggestions? Thanks so much for your help !!!

If you're not able to shift into gear at a stop, it could be a clutch issue.  If you just feel as it's not first and you don't want to slip the clutch to get moving, probably not a clutch issue.  Do the push start thing and get it into high gear, then downshift and count to make sure you have 5 gears.  The other thing might be that the sprockets have been changed.  It should be 18 teeth front sprocket, 48 rear.  They can be off by one on the front and as many as 3 on the rear without causing the symptoms you describe.
