I am ready to install the cam on my trx 300. I am trying to determine if it is on the compression stroke or exhaust stroke. Can anyone tell me the difference ,with the cam uninstalled, or does the sparkplug fire on every revolution? thanks

 

You just line the "T" up with the index mark ..

 

thanks again hondamech . does the plug fire on the exhaust stroke in normal operation? btw ,nice icon [img]i/expressions/face-icon-small-wink.gif[/img]

 

Yes the pulse generator runs off the crank/flywheel so it fires every stroke .. If it ran off the camshaft it would fire every 2nd stroke ..
