Worked on the Baja a fair bit today. Changed the oil, pulled the clutch to measure the shaft just to be sure, went ahead and cleaned the clutch and oiled the bushing while I had it off, replaced the missing master link on the short chain, lubed the chain, and adjusted the throttle cable to get it to open all the way. I don't think the previous owner ever had full throttle! Although, they really didn't need is as all they did was make laps around a 1/4 acre lot. Went ahead and threw in a 140 tube with the stock jet. Hit a road block though when I couldn't get the brake adjusted. I pulled the rear drum to inspect and found separated brake lining. Ordered a cheapie set of shoes off of Amazon to get it going, but also ordered the Honda shoes off of e-bay.
I did put everything back together enough for a little test ride around the yard. Can't compare performance fairly to the 200 EX as they are geared differently, but while strong, the engine certainly doesn't seem to have the thump of the lightly modded 200 EX (yet!). While similar to the Coleman at first glance, the Baja is quite a bit different design. The riding position and handlebars are much more upright resulting in a very different feel. I haven't measured, but the wheelbase might be a touch longer on the Baja as well. Once I get the brake shoes on, I'll do a top speed run just to see what it can do with the stock setup, but that won't last long as I have torque converter (OldMiniBikes), spare belt, and proper lug nut ordered
