Glen,
New build, second tank of gas (very low miles). You're right about the gap. I did everything initially according to spooky directions, which said to gap the Chinese pluig at .36. There were no instructions for gap on the NKG, but just last night I read (after using the search icon
) "you should never gap an iridium plug" just after watching a NGK video about how to gap NKG iridium plugs lol. So today I will set the gap back to the factory on the NKG (.18) or maybe .20 after what you said? The NGK video said to never use a traditional gap tool because you can break the tip easily on the iridiums, so I may go buy a better 'feeler' tool.
BTW, I use the search constantly (my favorite icon!), but only turned up one thread about a "gray plug". That's when I started searching the net.
Arkives1,
Well I did post in the 2 stroke forum
JK... yeah it's a 66cc skyhawk.
Again you're right about the oil mix. I had it at 20:1 and was still having issues with getting the bike to perform well. I was reading up on oil ratios here and it seems there is no set consensus...more personal opinion/controversy. I read the argument about 40:1 being used in all 2 strokes and it looked convincing so I tried it out, and I noticed a big difference- ran much smoother. I was was running too lean at 20:1, and I had a bunch of oil dripping out the exhaust which I read is normal, but I wasn't a big fan. I'm going to compromise and change it to 30:1.
I don't believe so. Not sure how to check, but I'll do a search.
If you're running a high capacity air intake and the muffler can't exhaust it with the correct back pressure you'd get performance problems.
This CNS 'speed' carb comes with many of the Grubee kits now, and has an extended Z intake to get around the seat tube. Some people love them, and some hate them. I'm undecided because they do require much tweaking IME so far.
Like I said... I had/have the bike running well. Maybe the excessive heat and smoke is par for the course. I was surprised how hot the plug boot was though 10 min after killing it. The plug has 2 great reviews on Sick Bike P where I got it.
I'm going to do some more tweaking, but I have
one main question:
Even though the NGK plug can still be used after what appears to be some fouling from carbon build up.... Should I use a new white plug and test it every time until I achieve the desired tan color, and then switch back to the NGK so I know my engine is running at the correct air/fuel and have the peace of mind that I won't damage my engine eventually?
This tan color is pretty important from what I've read.
Thanks again guys, I appreciate it. I'm learning a lot as I go, and spending hours on this forum which is a life saver.
