Hello All,

I am try to get this bike to run right, which is almost there. I noticed that the timing on the bike was not set correctly because I was getting backfires through the carb.

I figured out how to adjust the timing and was able to adjust it by ear. It is ride/running a alot better but again I timed it by ear.

Can somene point in the right direction of this inspection hole to check the timing. I have been doing some reach for the inspection hole and came across a tool (HD-96295-65D) that is a plastic cylinder that goes close to the flywheel. Is this tool needed?

Also, in relation to where the timing adjustment is, where is this inspection hole, I was looking inside where the ignition module is and I dont seem to find it.

If someone can post a real picture of where the hole should be or even a good illustration. The exploded view is too close and I dont see where the hole should be.

Thanks

 

If you have a stock ignition system, it is mounted on the left side of the frame up by the neck. All you have in the nosecone is the pickup.
This is best done with two people, so get the 'ol lady in the garage with you. Pull your plugs out. Raise the assend of the bike off the ground so you spin the back tire. Place the bike in 5th gear. Looking in your timing hole on the left side of your engine case, rotate the motor with the back wheel until the vertical slot on the flywheels is at 12 and 6 o'clock of the timing hole. Your front piston should be at the top. You can verify this by sticking a screwdriver in the sparkplug hole. Move around to the right side of the bike. You probably already have the nose cone cover off. The ignition pickup should be close to being centered up in the slots on the left and right of the backplate, if it isn't, center it up in the slots.
Moving back to the left side, rotate the motor untill the drilled dot shows up in the timing hole. Get a magic marker and mark the hole.
Replace the spark plugs and wires, drop the bike to the ground and put it in neutral.
Hook up the timing light to the front cylinder and to the battery.
Here's where it gets messy. Get a set of safety glasses and a clean rag. Start the bike, and rev it to at least 2000 rpm, put the light to the timing hole and see if can see the drilled dot appear. It should be centered, if not, have you helper rotate the backplate left or right until the dot is centered. Oil blowing out of the hole is going to cover the light and your safety glasses. You are just going to have to work through it. I found that little plastic plug doesn't work.
Now, on some models the vertical slot is the advance mark. Whatever shows up in the plug hole is what you want to center. The other mark is about 39 degrees away, and there isn't enough adjustment in the backplate to accidently center the wrong mark. On some models, there is also two drilled dots together, thats the rear cylinder advance.
Let's get on to your real problem. Check your carb mounting and see if you have a intake manifold leak. That will cause sneezing and backfiring through the carb. The carb is leaning out, and if it is the stock CV carb, it could probably use a rebuild. Hope this helps.
