I wish I had someone to tune in my motor, change jetting etc etc. I'd be GLAD to pay!!Originally Posted by xrider
The bike is all together now and tuning is just about complete. I got a voicemail from my friend who is tuning the engine and the best run so far hit 27 HP. This thing should fly. He said it pulls hard through the entire powerband. I'm picking it up this coming Friday and will give a ride report and post the dyno charts and pictures! Thanks, xrider
Very tough to tune these with the newer carbs........ But, so much to gain.........

The 200x is Done! I am picking it up this coming Friday. Below is the Final Dyno Chart. We had it tuned into 27 Hp at first but we downtuned it slightly for better idle quality. Final numbers are 25.56 HP at 9000 RPM and 16.33 lb-ft of Torque at 7400 RPM! This thing screams up top and pulls hard from down low. I'll get some pictures of the whole bike up this week!

Picked the bike up Friday and finished it up. Ignore the missing tank shroud and the old swingarm. The tank shroud is at the painters and is being used to match the paint color on the fiberglass lowpro fenders, and the swingarm will be replaced late March early April with one being made by Billy. I ended up relocating the upper tank mounts about an inch higher to eliminate the tank/seat gap. There is tons of snow and ice here, but I was able to ride up and down the road a bit with it. This thing screams! The throttle response is amazing with the FCR carb and there is no weaks spots in the powerband at all. Great bottom end and midrange and a killer top end. It sounds wicked, almost like a big bike when it's revving. Right now the gearing is 14t up front and a 38t on the rear. I will definitely have to drop a couple teeth more in the rear as this thing flys through gears. First real test will be February 26 at the Summit Indoors race!

What is the swingarm going to be?Is it hard to ride with a stock length swinger?By the sounds of it with that light little trike it must be a handfull.

The swingarm is going to be a Westcoast styled +1 length that will be heavily gusseted with Dico style linkage. The swingarm that is on it is actually a +2 extended stock 1983 200x swingarm. I'm sure with a stock length swingarm it would definitely be a handful.

Sweet 200X... I just got done with a powroll stroker but without such a big bore with a bigger titanium intake valve and a ton of headwork. Checkout the step exhaust on my profile, I built it to there specs except the can. Powroll said supertrapp but the head guy and tuner said straightline freeflow so im trying different stuff. Its a very straightline run back to the can with three steps bigger, theres no atv dyno around so I cant get any numbers. Im going to be building an aluminum swingarm for it when I get some time, setup my brembo rear brake system. I built it because ive always been a 200X nut and I had a curtis sparks 200X years ago that I absolutely loved... Nice bike man!!!

Thanks for the good comments guys. Sdb69z28, I checked out your exhaust on your profile and it looks excellent. I dyno'd this bike with a Dycorp, DG, Bassani, and Supertrapp exhaust. The Supertrapp and Bassani were the best, but the supertrapp had a better overall torque curve so I went with that. If you're running an exhaust like that on your 200x, I would suggest upgrading from the stock carb setup. A 28mm Mikuni or Keihin should really help your numbers, depending on how much head work you have done. I would be curious to hear it though, it looks like it would sound awesome. Thanks, xrider
