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. www.babbittsonline.com/pages/parts/viewbybrandand/parts.aspx

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 dwell angle on a 3f engine if point gap is 18 thou


dwell angle is the no of degrees rotation between points closed and points open and for example on a 4 cylinder engine ( 4 lobes =90 degrees the dwell would be around 45 degrees available
there is an adverse relationship between point gap and dwell angle
the closer the points the bigger the dwell and conversely the bigger the gap the smaller the dwell angle
in a distributor the point gap of 18 would have a large dwell angle and that affects ignition timing
in your workshop manual there will be a dwell angle specification and if you set the points at .020 " that will put you close to the dwell angle specification
from there you adjust the gap to obtain the dwell setting
after yo have the dwell set , adjust the ignition timing
there is plenty of information on dwell angle, /point gap if you type in ---dwell angle to point gap relationship--

What is the points gap?


Points gap was used before electronic ignition. The "points" were a set of contacts found under the distributor cap and rode a cam that opened and closed them at the firing point you set with a timing gun (a gun shaped device that flashed light, when the first cylinder plug fired) aimed at a scale on the front of the engine overhanging a mark on the crankshaft pulley. The points were set to a gap suggested by the manufacturer.

How to set the points on a 1973 yamaha lt2 100


I do not know what the dwell or correct gap would;d be to get the correct dwell so I cannot help that way. You will need to google it or get the gap and/or dwell from a Yamaha or other such service center. To change point gap normally there is a screw which will loosen and allow the points to be moved (one side of the point assembly) so that with the cam that moves the point assembly apart on the middle of the high point the points can be set with the required gap between the open points to give the required dwell for coil primary saturation.,

Spark Plug Gap is .032 inch. Many have started using .035 as it is easier to set using most newer tools.

Point Gap is .016 inch. You may also set point gap by using a dwell meter if you have one. That setting would be 32 degrees.

What is the point gap setting for a 1969 AMC V8?


generally speaking we look for 30 degrees dwell,but setting the point gap at 18 thousands of an inch work well,then adjust the timing. dwell changes timing but timing does not change dwell,so adjust the points first then set the timing

When setting the points, I think the gap is set at .015 is that correct? Do you set the points when they are on the high or low side of the lobe ? ed


Yes, the point gap is .015

There is a line etched on the face of the point cam. This lines up with the rubbing block (cam follower) of the points. This is the position that the gap is set at.

I have 1981 Yamaha SX 650 and can't find the point gap and valve adjustment settings anywhere? Any answeres


Hi, the points gap is 14 to 16 Thou. Inlet valves 4 thou, exhaust valves 6 thou. I dont know the settings in metric, so using a set of imperial feeler gauges, that measure in thousands of an inch.
An easy tip for setting the points, is use the thickness of a standard cardboard, Business Card, it is the correct thickness for your points gap.
