The base setting for the point gap is 15 thousandths. Set the left cylinder to .015 and check the timing with a timing light. Adjust the timing for the left side by moving the base plate up or down. Now change the timing light to the right cylinder and check the timing for the left cylinder. Adjust the timing for the left side by changing the points gap if the left base plate can not be adjusted, ( I can't remember if the left plate adjusts or not ). The wires should not be grounded. Check to see if the timing advances as it should when the revs increase. Below is a photo from an 1979 RD400 owners manual. Yours looks the same.

f9ff258.png Go to the site below where you can see a parts diagram for your specific bike. You will select the actual brand, year, model, etc., once you go to the site. Part numbers and prices are also shown. You can order parts from this site. In the event no price is shown on a particular part and/or the notation "Not Available" is in the description, the part is not in stock. It looks like they have points for a 1975 RD350 and they should work on your bike.

Yamaha can tell from the VIN what exact year and model your bike is. Check with them as I don't think the 350 was made in 1979.

Point gap will be .14. Make sure after you set the points at .14 you attempt to insert a .16 feeler gauge. It should not go between the points without moving them. Also, a .12 feeler gauge should slip in without any force.

Several things could cause this and are somewhat inter related. I would clean the carb inside and out to start with. Check the reeds for cracks, chips and distortion. The cost is only a can of spray carb cleaner. Timing is not likely to be a factor. Use a timing light to check if you wish, again the cost is little or nothing. The most likely causes are bad crankshaft seals and/or the need for new seals on the intake assembly. The metal carb fits into a flexible fitting between it and the reed assembly. When the fitting gets old and hard it tends to loose it's ability to seal. Often they will develop cracks that let in air which leans the fuel mix. When the engine warms up the cracks widen and the engine runs poorly.

What is the ignition point gap?

In older engines with traditional points-condenser-coil ignition systems the dwell if the ignition was set by the gap between the points. The points act like a switch that opens and closes the circuit of the primary side of the ignition coil.

All later engines use electronic ignition that do not require points.

Are you sure you have the plug wires on right, and the point gap is right ? I am assuming you have checked the carb and ruled out a fuel problem.

Ignition plate coverd with carbon deposits @100 miles, must clean them with eraser or engine misfires, won't start. Cause & remedy? Thanks!

I believe that the 1980 Xs650 still used points and condensers for ignition. I know that my 1979 did. I would check to see if you had a bad condenser. That can mess up the way that points are firing and can cause excessive carbon build-up. I'm not sure if the condensers are sold separately from a points set, but you can always buy a matched set and only install the condensers so you don't have to reset your points gap.
It might also be worth checking the voltage coming into the points assembly. These Yamahas are known for bad ground points, which can spike or drop voltage at points in the electrical harness. You might be getting odd output from the rectifier, which could be due to a bad rectifier or simply bad wiring connections. But my immediate inclination is to test or simply replace the points condenser(s).

The bike is starting only with small plug gap.If we set the gap to original it wont start? tell me the reason?

.....A weak battery comes to mind for starters. A carboned up spark plug is another; start with a new spark plug. If I recall correctly from 39 years ago, your bike has ignition points and condenser. Remove the points cover (on left end of the overhead cam), and check the points. Burned? Pitted? Get a new set of points and condenser but for now, just file the points a bit using an emery board or metal fingernail file. Set the points to .015 clearance at the high point on the cam lobe. If you have a timing light you could check the timing and adjust as needed by rotating the points base plate left or right. Bad points give resistance to the flow of electricity. When the points are closed, the condenser gets charged up. Less electricity going through the points means less of a charge going into the condenser. Now the points open up and the stored charge goes from condenser to coil. The coil then produces a spark. With a low charge in the condenser, the spark is weak and will not jump a wide gap. Set the plug gap to very little and the weak spark can jump the gap. The standard gap is .028. ....... I don't recall when Honda move the points to the flywheel but the images below may help if your bike is that style. Clean any rust on noted parts; magnets and pick up coils. Okay, now I have done my part. Now you gotta do yours; please rate my answer. Thanks! tombones49_177.giftombones49_178.gif

You are probably dealing with dirty,burnt,or shorting points. Try replacing the points located at the end of the crankshaft under the cover held on by two screws. You may have to install and reinstall the points several times before you can get the new points to work. Chances are the points in the machine are almost 40 years old. Also , Honda ignition systems run off the battery. In most Honda models if you do not have a good, charged battery , you will not get spark.

Put new ignition coil on, however still no spark

Im sorry you are having this trouble with your CB 100. I had a CB 100 from '71.

So you have power going to the coil? How are your points and condenser. I think your trouble is probably your condenser complicated by points that are not properly set. Set the points to .035.

Check these things and try again.

FYI, there is a Honda Riders Club sponsored by Honda and free to browse. If you pay a few bucks and joinn the club, you will get immediate access to service manuals for your model, according to information posted at the site.
