No I was afraid to try getting the ball and spring out. Thought I would never get it back together. It was stuck but I got it freed up using an ultrasonic cleaner. I have not put it back on the bike yet but if I leave it set dry for a couple of days it sticks back up.
Please don't BAN me for asking.
Is it possible to purchase a NEW accelerator pump housing for this bike ?? I'm asking about the part with the check valve.
Thank you in advance. Larry
Does the rear of the seat "fairing" bolt to anything or is it just the 2 bolts on the middle side of the seat??? The rear of the seat "fairing" seems to loose.
Thanks
You might be right on the primary chain tensioner. I just went and started it cold and the tick was there for 3 sec. Restarted it several times and NO tick. Waited about 15 mins and restarted with no tick. So you think chain has stretched to limit??? How big a job is this ???
Just turned 30,000...
I have a 1980 CB750F. Bike runs great. It has a light ticking sound when I first start it. It only lasts for 2 or 3 seconds. It sounds like a lifter tick but I doubt this bike has hydraulic lifters but I'm not sure. Oil is changed regularly with the correct weight.
Any thoughts???
Thanks, Larry
amc, thank you for the update. I thought about the issues you mentioned in 1 and 2 above. I will read the entire link you sent . Looks very informative. I'm going to do some more testing and reading. Do you or a friend have a 750 around a 1980 model? I would be very interested it what it does...
I decided to move the airbox back to see what the chokes were doing on the other three carbs. As you know and I found out that the left and right choke rods turn a spring and are not connected directly to the choke. I'm thinking that maybe at 5,000 or 6,000 rpms the incoming
air overpowers the...
well I pulled the rubber for carb #1, and low and behold the choke blade completely closes. I see the shaft that closes the choke and it is moving going to carb 4. Can't see the middle 2. How can I pull the choke full on and it hardly effects the performance at 5,000 rpms ?
I'm sure you can put...
Thank you for the reply. I will pull one of the outer rubbers and see what is going on. Yes it will just fly past 9,000 rpm but I try not to go above 8,500.
Do all four of the carbs. have chokes??
Larry.
Hi guys and gals. Great little forum you have here. I'm sure I will learn a lot. I have a 1980 CB750F in great condition and have a question about the choke. I don't believe mine is working properly as it is hard to start. How many of the carbs. does the choke effect? Is it a blade type choke...
