Is there any reason to avoid a larger idle jet? I'll order up a #35 from absolutelyscooters and see what happens since that's what they have in stock and they're the first ones I found that offer the extended length idle jet for easier starts. But I still don't understand the reasoning if my current setup seems fine, is there some chance I'm running too rich at 1/8 throttle?

The first few plug chops consisted of a five minute warm up in idle and a ten minute drive at WOT. The last plug chop was a longer drive because my mother asked me to go to the store for her - I got much better results with the longer drive, that's for sure. Sadly it just so happens that a lot of roads were flooded around town so I was confined to a small strip of road on 120 since my speeds are too high to do WOT around the neighborhood anymore.

Clean, or lean? It may just be your opinion, but I value your opinion Buford.

You think so? I've been running a restricted free flow filter for months now because I didn't have the proper jets. Millsc says I shouldn't have to go over 95 with jets and I'm trying to get the best performance possible - won't the restriction hinder that? I mean... the tip of my spark plug is white from my hotter coil, but the base is coffee colored - isn't that what I'm looking for?


In any case I'm ecstatic that I can almost hit 60mph now. I'll try a smaller idle jet for some reason, but otherwise I'm liking my setup so far.


Thanks for the input, Y'all!
