they're a great bike for sure, you should try the 300.
As your 2010 is essentially the same as my 08 i'm wondering whether you have some of the same issues i had. I still haven't come to grips with the Marzocchi's, find them far to stiff in the initial stroke.
Check where your carb meet's your airbox mine was a mile out and i've radiused the carb bellmouth. Match porting was also required at the carb, boot, reed cage join.
Check this forum, i've got some pics up on it.

Thanks for the pointers.....
While you can get a great initial impression of a bike by getting a chance to try it before you buy it, they all need some work to get them set up. For the forks, have you backed off in a big way on the compression damping? Also from what I have read they change the Marzocchi forks on the bikes, maybe sourced different ones? These are the Shiver forks....
Mike had been sponsored by Marzoocki a few years back and is very familiar with them. Plus he rides very hard and this bike seems to respond to very aggressive riding.
Actually that's a great point, if you are a beginner or novice, this bike is probably not for you. A few other guys rode it, they were a bit uncomfortable because they got off their bikes and rode this afterwords. So they were a bit tentative with it.
One racer Devin, gave it a try and he came back saying that he had a 2005 KX125 full Pro Circuit motor set up and the TM was way faster than his... the TM is stock from the factory.
The other comment mentioned by almost everyone is that the bike has almost zero low end, and not much in the way of mid-range, but it screams up top!! Because of this I would only recommend this machine to someone that can handle all that power, be aggressive on the track and have the skills to dance on the shift lever. This bike is not for everyone!!
When I spoke to the distributor to tell him our experience, he said, "You thought the bike was fast? It really doesn't get fast until you run 2 or 3 tank fulls of fuel through it." We'll definitely report back on this!
As for the internals, we'll get to that. I want to ride it stock until it needs a set of rings, then we'll tear down the engine and take photos. Anything like what you mention will be pointed out.
The bike does draw a real crowd... it's certainly stands out from the crowd! Of course it will look like new when it goes out again!!
