Hello everyone,
I am new to the forum. I got a good deal on a 1979 CB750L.
It is in great shape overall. It just reached 15k miles on my 25 mile ride home. It runs ok, shifts well. So far, seems to need new front brake pads. These act like they were oil soaked (as in fork seals leaked on them). I plan to get new pads via Amazon. Unless there is a better place.
I was told this was sitting for a while. There was some surface rust in the tank. The rust wiped off what I could get to with the fuel in it. When it's cold, with the choke on, it takes two starts to get it going. Then I quickly turn the choke down. It seems to run and idle fine for a while. When it is up to running temp, it will slowly lose idle and die. The PO turned the idle screw up for me. Now it tends to idle around 1800 and "sticks" at 3000. If I snap the throttle it would go back down to about 1800.
I was reading some forums here. Seems I should check compression on all cylinders. It could be valve adjustment time. If the compression checks out, then clean the carbs. I am not 100% sure if I can just sync the carbs, or do you think they need a cleaning based on this information?
Is there a good place/brand to get carb rebuild kit?
Again - It seems to run well at all speeds and gears. Just an idle issue that I can tell.
TIA
