I am trying to get one running and wanted more info on there. ANyone have a good site with specs and reviews, write up...
Some questions I have.
What carb does this thing run (92 dr250s)- BST 28mm
samme air box and duct as the 350?
Horse power. Read it has a 29hp max. the site must be wrong.
CDI is it interchangeable the the 350's
Stock sprocket size?
According to my Suzuki manual, the '92 DR250S carb is a Mikuni BST33SS. The DR250N has a Mikuni TM31SS.
Unknown regarding the airbox & duct similarities. I don't have a 350 to compare it to (yet).
I can't find anything in the manual regarding horsepower, although I would agree 29 HP seems pretty optimistic.
I have read 250 and 350 CDI's are different in advance curves due to the 250 making it's max power at higher RPM compared to the 350.
Stock sprocket size on my '94 was 15/43. Nearly all my riding is on single-track, so I changed it to 13/47.
