A tip for new and perhaps old scoot owners, check your spark plug!
I just picked up my Iridium plug yesterday, got it at ORielly Auto Parts for $7.50 including tax. While I was installing it I noticed that the old plug was VERY loose, so loose in fact that I didn't even need the ratchet to remove it! I simply removed it by hand using the socket! So, during your next 'once over' of your scoot, take a couple of minutes and make sure your plug is tight.
On the Iridium plug? Did not notice much difference.

Even if you don't notice a lot of difference with Iridium, it will burn cleaner and last much longer.

when you guys put your plug wire cap on your plug does it have ALOT of play in in mine does I tried putting the scoot on the center stand and reving the engine while wiggling the plug wire and could hear a difference in how it ran but it just seems too loose.

Not quite certain what you mean about a lot of play in the plug wire. One thing I did notice when I changed from the Chinese plug to the NGK plug is that the porcelain shank of the NGk plug is shorter than that of the Chinese plug. So what, you ask. Well, the rubber spark plug boot was too long for the NGK plug and would not secure properly to the thread stock on top of the plug. One day, just after I started the scoot in preparation to ride, it quit a couple minutes into warm-up. Would not re-start. Had a hunch and pulled the access cover - boot had popped up off the top connector of the plug. Solution was to cut 1/4" off the bottom of the boot - it had this stepped-down area at the bottom of the boot that was easy to cut off. Don't know about other spark plug boots but mine sure was a problem with the NGK plug. Glad it happened at home instead of on the road at speed!

I have an NGK CR7 plug in mine and I meant it seemed like it wasn't on the plug tight it didn't pull of easily it just had a lot of play side to side. seemed as if it might not be seated on the plug but it ran okay when I wiggled it.

That is the same plug I purchased and installed in my 150and described above. Did you remove/leave off the threaded cap from the top of the new plug? Check what I described in my previous post. If you noticed some difference in how it ran when you wiggled it, the boot may not be going down far enough to engage the threaded top terminal of the plug.

Actually, once I got the new plug in, and tightened correctly, the plug boot fit perfectly.

Now I understand! At first I thought you meant the boot wasn't seating properly. After I Re-read your first post I see what you meant by the wiggle. In the past, I have also discovered plugs at times that were not torqued down, just hand installed. Quality control!!! Ordered the Iriduim plug this A.M. Curious about it's effect on idle smoothness.

Scary... Another thing to watch out for is when installing a plug, be careful not to drop it down in between the engine and the outer plastic covering. That sucks because then you have to take the covering all off down to the magneto area and get the plug out from there.  ( |

Does anyone ever use the copper antisieze grease?

Have used it on every plug in every motor I have maintained for many years. Would not install a plug without it. A great recommendation for folks new to motor maintenance. Even pull plugs in new engines to make certain some type of anti-seize has been used. I believe this is even more important today than in the past because heads are aluminum instead of cast iron.

I've been using it on plugs, and bolts that need to be removed often. Haven't had a thread damage.
