Am I Too Lean? (pics inside)

[MadMike2288]

I just installed some boyesen power reeds on my 90 blaster. I also removed the airbox lid and put in a 250 mainjet. I went and did a plug chop with a fresh plug and the plug came out pretty white. This got me worried so I put the airbox lid back on and put a 230 mainjet back in. Did another plug chop and the plug came back pretty much the same color maybe a little darker. I then put the 250 back in with the airbox lid back on and did a plug chop and the plug came back a little darker than before but still pretty white, so it has me worried. Before I put the power reeds in, it was running perfect. The previous plug I was running came out real nice and tan, maybe a tad on the rich side but nothing to be concerned about.

Here are some pics of the first plug chop, with the power reeds, airbox lid removed, and 250 mainjet. Could the power reeds cause the quad to run lean even with the airbox lid on and the 250 main? The instructions that came with the reeds, state that the reeds may cause the bike to run rich on the main and lean on the pilot. I'm pretty confused about this whole thing, so any help would be great.

Currently I'm running the 250 main with the airbox lid on, it still seems a little lean, will adjusting the air screw richen it up at all. Everything else on the quad is stock except for the power reeds and 250 mainjet. The air screw is at the stock 1.5 turns out, and I'm at 3300 ft elevation

in order to do a proper plug chop you must actually cut th threads off the spark plug. that is if you have done the test appropriately.
1-warm up on used plug
2-put new plug in and go for a full throttle run all the way into 6th.
3-cut engine while still giving it to it
4-come to a stop and take the plug out without any other riding
5-cut threads off plug and look at the base of the porcelin

Ahhh.. thank you, I just did a full throttle pass in 6th then killer the engine. Are these pics worthless then, or can anyone tell anything by them?

pics are no good for a true reading.BUT you can still use it to warm up the engine and then again after you chop the other NEW plug for your reading.
cant have any runs at all on a plug to do a good chop

That's not a plug chop......all you did was pulled the plug out of the head and looked at it.

If you warmed up with an old plug, and put in a new plug(looks like you did), then you are fine. You simply have to cut the threads off the plug.

How do I cut the threads off, what tool should I use. I'm pretty limited on the tools where I am living now.

 

[98blaster+4]

i use a 4" grinde with a cutoff wheel. you wanna cut the whole threaded section all the way around and it will come off giving you a true reading down at the base of the insulator......and leave it right in the plug socket, makes it easier to hold onto while cutting

hacksaw works. cut that plug and post pics

 

[MadMike2288]

Hard to believe but I don't even have a hack saw where I'm living, time to go pick one up.

You def need some more time on that plug .
Pop the 250 back in and remove the lid , go ride it hard for 15mins and come post another picture.
Theres now way your running lean with a 250 main and just the lid removed. Usually reeds dont require much of a jettin change.

You dont need to do a plug chop.I can tell you how your engine is running just by looking at the plug and verify the amount of smoke comming out of your exhaust.No pun intended plug chops are fine if your looking to grab every bit of peak performance as if you were racing but any way.My preference is tan but on the oily side.This lets me know that the piston is well lubricated and cooled for longer life.Really does not affect performance.I run on the rich side and run a hotter plug as well as raise the needle one slot.If your plug has white or grey ash then you are running to lean.If your not smoken your blowen?

No way in hell can you tell by the amount of smoke. You can be running lean, and detonating with more oil in the mix, and it still smokes the same!

Keep the b8es.

Do a plug chop!

Your quote" If your not smoken your blowen?" is bull dust.

Did you do a leak down test after you fitted the new reeds, the chances are you may have created an air leak around the reed cage or carb boot.

Common problem which can be rectified by using a sealant on the gasket.

Try sealing them up and torquing them incrementally and diagonally to 5.8 ft lbs.

Not everyone shares your special gift. For the rest of us mere mortals, plugs chops are the way to go.

A dremel is what i use for the plugs to chop the threads off.

For the record plug chops are the way to go and pretty much the windorw into how a 2 strokes running.

Get yourself a box of 4 BR8ES plugs and experiment.What are your mods and why did you rejet for reeds?

You sir, have a gift. You should keep doing that on your bikes and let us know how it works out! 8-|
