I have a 1990 DT200R, with only 3500 km on it. Have had it for 6 years or so, and have not ridden it much. It was working well, a couple years ago, but is now using a LOT of fuel and will not run cleanly at a steady speed. Compression is 140 p.s.i.. It's stock. Cleaned out the carb and replaced the "float needle and seat". Replaced the pilot jet and cleaned out the main jet. Had to coat the tank two years ago, due to rust, but it looks good now. Spark looked good when I kicked it over with the plug out. Noticed the petcock is leaking a bit right now, and have ordered a "rebuild kit" from Wemoto in England. My intuition says I am missing something in the carb.?
Do any previous/current owners know what speed a person can cruise on the highway at, reasonably? Top speed? Also, what fuel mileage would you get out of a tankful? Maybe at hwy. speeds and at slower off road/gravel road speeds? Any help would be appreciated.
I'd lusted after a DT200R since I first saw them in Cycle Canada in the late 80's. Then when I saw one in a dealership, I was hooked! When it's running well, it'll keep up to a lot more expensive iron, I believe. Also, it's a TWO STROKE! Thanks again for your help.
