The flywheel cover will need to be removed from the right hand side of your crank case. You will probably need to remove the shift lever from the shift shaft too. This is accomplished by removing the bolt from the lever with a 10mm wrench and sliding the lever from the shaft. Next remove the #2 philips screws that attach the flywheel cover to the case. When you get the cover off you will be looking at the flywheel. On the upper edge of the crank case there should be a vee shaped notch in the casting. This should align with the line marked "F" stamped onto the flywheel when the points are just opening. There is also a "T" line stamped into the flywheel too and this the firing position when the timing is advanced mechanicaly with the engine running. This can be checked with a timing light at about 3000 rpm. I can send pictures if you want to email me.

Sounds like the jets are clogged in the carburetor. Try running some carburetor cleaner through it first. If that doesn't help then you will need to have the carburetor rebuilt. Hope this helps. Good luck.

Brand is not really important. Just go to any motorcycle shop and tell them you want road tires for city streets. They may have two or three tires to choose from. Pick what looks good and go with it.

I believe your bike takes a 250 x 18 tire size on the front and a 3.00 x 17 on the rear. Look at the sizing on the sidewall of the old tires.

They are not a rocket ship, but I would expect closer to 50mph .
need good air filter element.
ignition advance springs can cause a problem, or the advance may be sticking.
need good battery, recheck point gap, timing and valve clearance.
check for exhaust blockage(see if it revs better without the muffler)

You have probably tried most of these, but there is not much else, they should rev sweetly right though the rev range

Where are the timing marks on a 1970 cb 350


On the left side of your engine, you will see a round cover. If you remove this round cover you will see a fly wheel with a big bolt head, if you spin this bolt head with the engine in neutral. You will see marks on the fly wheel, these marks are your timing marks.
