I have a 200 that has some motor mods performed, yes it will loft the front end to a degree.
One think to keep in mind is, the 200-300 is pretty much all the same bike, so the overall weight is pretty much the same. If 250 or 300 feels heavy, then the 200 is really close to the same weight with less hp and torque.
I think it would be safe to say that there is a difference in power delivery and overall power between a 200 and 250, and.....a 300! Riding a 300 monster after you've been on a 200 is a complete different program. I have plenty of seat time on Kevin's EC 300 and jumping from a 300 onto a 200 I can see how this guys is feeling like he is missing something......he is..about 99.6 cc's!
I am not sure if the gear box of the 200 uses the same gear box and overall ratio's as the 250 or 300?? I only ask this question because what other guys run on a 250 or 300 just might not work well on a 200.
I see there are several guys using a 12 tooth C/S sprocket....that seems a little tight for me, but who am I to judge what another person uses.
I agree with Hamilton, about the crisp jetting, tapping the clutch to clear trail trash.
The 200 likes to be ridden like a 125 on Red Bull, Yes the motor is very smooth and electric and linar, but it lacks overall robust, yes it can be lugged and will pull cleanly may require clutch work, or a down shift.
The area that I race and ride in is some what tight wooded single track, but nothing like back east, I have ridden in the PNW on my 200 and I was using 13/50 gearing.
I have used 13/48, 49, 50 and 51.
13/48 - requires to use first gear too much, I like to use first gear as a "bail out" and I don't like hitting netural.
13/49 - is pretty much the same as 48, but with a little less 1st gear work.
13/50 - seems to work really good, keeps you out of first gear most of the time, better use of 2-4 gears still maintains good topend speed for transfer sections and is alot more foregiving than the 13/48, meaning if you find your self in the wrong gear, a little feather of the clutch, and throttle can get you out.
13/51 - really works 3-5 gears, some topend lost, second and third become the work horse and 4th gets used much more. Less clutch use, but requires more shifting throught.
I have a 50 and 51 hanging in the shop, my go to gearing is 50, I feel it provides the best overall gearing for WHERE I RIDE AND MY STYLE.
If I lived in the PNW, I would be slapping on the 51 or larger based upon my time on the trials up there in Norther Oregon.
IMHO, after coming off a 300 and going to a 200 is going to require the pilot to change to a more aggresive riding style. You can ride a 200 like a 300, but your going to fall off the pipe, bogging the motor, be in the wrong gear and could be frustrated. The 200 likes to be attacked, aggressive style, ringing it out to a degree, on the pipe.....it begs for it and that robust motor can and will handle everything you dish out, just like it's bigger brothers.
One more thing...after watching your clip ( I love that type of riding area) not knowing what ignation you have, 2k2? 2k3? a flywheel weight might not be a bad idea for your area.....food for thought!
