Plog chop

[gcautosports]

So i just did a "plug chop" on my banshee minus the actual chop since i dont have a grinder or dremel with me right now and want to make sure im not going crazy...but. is it me or am i runnig way too lean?

27.5 pilot

290 main

Needle in 4th position

No leaks

Compression is 112psi with snap on tester

its hard to really see, but to me if you look at the BOTTOM of the porcelain it kinda looks like you have a good smoke ring. If it were me, id chop the threads off and report back before you do any tuning.

[special06shee]

Your smoke ring should be about as thick as a quarter. When you do a wot plug chop your only reading the VERY BASE of the porcelain, nothing else. That is why people chop the threads so they can get a better visual of the base.

Was this done the standard way?

Warm quad up with other plug, then put new plug in. Take quad for a run at WOT through the gear and hold 6th pinned for a couple second. Shut quad off then check plugs?

 

If so, those plugs look okay.

 

This is a good look plug from doing a chop

 

Thats exactly how i did it and it looks just a tad lighter the only thing is that it boggs between 1/8 to maybe 3/8 throttle but ill go buy a dremel today thanks!

[gcautosports]

Or atleast it boggs on low revs.... when i punch it. it rips!

Op you really want to cut the threads of and look at the bottom of the ceramic. You don't need a grinder or dremel simply use a hack saw will take you 3 min to cut the threads off..

That's almost pure white with only a tiny hint of a tiny hint of smoke ring, I would say your def lean..

Its not the ring that worring me right now its that fact that it only has a "dot" of smoke as if it only fired once obviously it dodnt sonce i went through all gear and held it for 4-5 seconds at wot in override

May want to fatten your pilot jets. If your saying there is an 1/8 - 3/8 bog than its not your main jet. Start with the pilot and make sure your air screw is adjusted right..
