Today was a beautiful 75 degrees here in Vegas, and I've got 400 miles on my new 150cc fully broken in, so I took a nice ride. Coming home, I jumped on the freeway to see just what she could do. A bit of a headwind, and the stretch I took her on goes up and down rolling hills, nothing severe. I had no problem maintaining 60mph, but getting above 65 only happened going downhill, and I did nudge 70 on the longest downhill stretch. The tach was showing 6800rpms on that downhill stretch, never got her above 7000rpms, so I may have a bit more with some basic mods, but not much. I'm very happy with the performance on surface streets, here in Vegas the speed limit on major roads is 45mph, with people hitting 50-55 as a rule. I have no problem leading the pack from stop lights, and have decent throttle response, never needing to go WOT unless I want to.

BTW- The 16" wheels do make a difference at high speeds as well as on bad surface streets.

My Uncle has only driven Volvo his entire life. I'll have to shoot him an email and see what he thinks about the Chinese takeover, I'm sure he'll have a choice word or two, he's downright obsessive about his oldest Volvo swearing it's the best machine ever built.

Good to hear you had fun on your trip. I agree, the 16" wheels make a huge difference in handling. They make it harder to turn in tight situations I could rip through on my 50cc, but they make everything else smoother and more stable. The owner of Scrappy Dog Scooters asked me to stop by this week so he could check it out, they already carry lots of parts for the BN157QMJ-3, and now he plans on stocking tires as well. Good to know there's another option when I'm ready for new rubber.

Interesting, yet Lance still sells Znen built scooters under the SSR brand, or at least my dealer claims so. Sym uses 4 Chinese manufacturers, and their mission statement includes "collaborating with China" at the very beginning. While some like to distinguish Taiwan manufacturing from Chinese, it's not that simple. Much like most cars sold in the US, parts may be manufactured in one country, individual assemblies manufactured in another, and final assembly performed in another. Just part of what makes Chinese quality have so many question marks, you're not sure who built what?!?

If that model had come with 16" wheels, I would have gotten it. Love the lines, could look awesome with a good flame paint job flowing along it's shape!

Most likely an a/f adjustment would be enough, having the next size larger jet up from what you are currently running would be smart just in case you need to do a quick swap.

You can also use a dremel grinding disc to cut a slot across the heads of those screws and get them out with a flat tip screwdriver of the appropriate size. I personally replace with allen head screws.

On the subject of loc-tite, ever seen yellow? I've got it on my 50cc rear axle, it's either yellow loc-tite or the assembler didn't get a restroom break that day!
