Timing

[freshwaterjim]

how do you know where to set the adjustable timing plate?can you hear the engine knock if too much advance,does it run hot or no,and how much damage can happen if set incorretly???

It will run hot and you might not hear or feel anything. One of the results is holed pistons (melting a hole in the top of the piston dome). You can check for little sparkles on the spark plugs after doing a plug chop but the true way to check is to pull your pistons before you melt a hole and look at the bottom of the dome. If it's clean with no color you might be jetted rich. If it's black or dark brown you are running really hot and will melt down if you push it.

For trail riding you will not want to go over +4 degrees on your timing.

To set the plate at the selected advance, u use the split in the cases... Just line up the mark on the plate to the point where the cases meet.

 

The general rule for advancing timing:

+4 for trails

+7 for drag

 

These arent set in stone, but good starting points.

Great info screaming banshee! this is what i was looking for!

 

this means i am currently running +5 for my trial riding.

will 98 octane fuel prevent knocking ( havent heared it yet)

and also the melting?

 

Manny thanks!

Like I said, they are starting points..the +5 should be ok- IF all of your other mods are dialed in w/ jettin and fuel.

 

93+ octane should be just fine for the +5 as long as your compression doesnt need higher...Listen to your motor and check your plugs often. Let us kow if u have nemore questions.
