Spark Plug

[miltiadis_s]

hi this is the colour of the spark plug. does it mean the engine is running too lean or rich?

do i play with the air/fuel screw to lean it out or rich it up abit?

Thanks

second pic looks lean, but youll need better pics before you start playing with it,

cause first pic kinda looks normal,

but if your gonna start messing with mixtures and need advice, get some clearer pics,

plus did you do the plug chop correctly?

 

[miltiadis_s]

what do you mean by plug chop lol.

here are the new pics sorry about the quality.

Have you just been ridung around in a backyard?

If you have your sparkplug is fine.

mostly in backyard for a few days but did take it out for a bit of a thrashing.

i thought the spark plug was the problem for the engine on take off sometimes, bottoming out, it like loses power but then kicks back in.

is this a tuning problem?

There's a little thing called focus on a camera, try using it.

i put a ngk cr7hsa plug in and ran it for a few hour. this plug is even more whiter than the other. what should i do?

and what is this under the throttle lever?

 

[miltiadis_s]

anybody know?

should i try using a hotter plug? cr6hsa?

shouldnt the bike blow a bit of smoke, it isnt blowing anything so maybe its lean?

could it be the ignition lead?

please help as i am going riding in a few days thanks

the reason no one is touching this subject is its pretty obvious you outta your league here,

and trying to teach someone over a forum how to deal with mixtures is 1) a nightmare 2) gonna end is disaster for you 3) very time consuming writing it all out,

1) first up you didnt know what "plug chop" was (thats the first thing you need before making any changes to mixtures

2) you post a plug thats black, but than talk about your plug being white!

3) you think your 4 stroke should be blowing smoke,

dont think iam being mean here, iam just letting you know why no one is touching this thread, you best bet would be maybe try and find someone local who can show you what to do,

cause iam all for learning it yourself, but trying to teach and learn here is gonna get you in a big mess lol

 

[miltiadis_s]

well cant somebody atleast tell me what they think the problem is?

The spark plug is fine!
