Banshee Chad Posted August 12, 2011 Report Share Posted August 12, 2011 What do you mean by range? Range I mean main jet, needle jet, and idle. Do a pull where each would be the one working. Quote Link to comment Share on other sites More sharing options...
volcrano Posted August 13, 2011 Report Share Posted August 13, 2011 The left is 280 plug chop WOT up to 3rd gear. The right is 300 plug chop WOT up to 3rd gear + 1 ride down the street and back. how is the one with the 300 leaner looking than the 280???it also looks like u used old plugs for the chop and u cant do that.u gotta get the motor to op. temps.pull those hot ass plugs and install new ones.do a WOT run and kill the motor and roll to a stop.then put reg plugs back in to get u back home or shut it off to where u can coast into ur driveway.chop those new plugs.u should have a 2mm brown ring at the bottom of porcelain.if ur over its too rich,under too lean.i do agree with loco tho,i dont ever do the plug chops,i just look at strap and porcelain and have never burned a motor in my life. http://www.dansmc.com/spark_plugs/spark_plugs_catalog.html these are supposedly "perfect" plug pictures.these came from rz/rd 350 forums. http://www.rzrd500.com/phpBB2/viewtopic.php?t=5048&postdays=0&postorder=asc&start=30&sid=32ec94fb329f29be9ee9e71c7fdb2b62 very good info from this forum and pics of proper plug chop.
