Hey f,

IMO your air cleaner is not effective and your choice of oil is leaving far too much deposit behind... By it's composition, or by too heavy a mix.
But you didn't mention how many miles were on that plug...

and I'd be sure to get a second opinion. :)

I've been advised that even the best 'plug readers' require a new plug, run on only one short run, at full operating temp, with a quick throttle chop.
Less confusion, that way.

Well thanks guys :)

Goes to show how a little thought and a lot of reading up on a project can help! Being my second build I feel excited to have her pegged like that.

What a great forum this is!

OK so I tuned up the bike some more and added custom gaskets tweaked a bit here and there and removed the plug after several miles and this is what it looks like. I am using seafoam in the engine and I used 60ml to 2.5 gallon gas. Does the seafoam make a difference on how the plug looks anyone? I am also using 60 ml saber amsoil to 1 gallon gas (non ethenol). SO thats at 63:1

I think the plug looks better then the original pictures posted above before tweaking/tuning everything. Do you agree?

Looks like it came out of a four stroke!

I can comment on the 63:1 sabre mix, I've never used it or any oil at that ratio.

I am sure someone else with more experience will chime in shortly.

Well crap I thought Imatched the spark plug color chart under the best perfect :(

Ok so Ill bump the c-clip on carb towards the bottom (pointy end) one. It is second from bottom Ill go to bottom location.

SO i guess ill go to 50:1 I mixed up the saber amsoil with the other one run a tank and check again.

Better on the richer side then the leaner side i suppose :)

ran crappy with c clip on bottom so ill just use 50:1 check it is after several miles and adjust accordingly to just darken her up a bit.

Unless someone wants to add some input.
