Kit 200CC to upgrade the Yamaha dtr 125
-
Hi @Louis-James parts are going on an 03 dtr and already fitted a 4 degree advanced woodruff key i made. The cylinder, head and powervalve have all just been custom made by BAracing in Portugal and all the porting a lot higher spec than an old 3xp cylinder for example. They build a lot of quick bikes with lots trophies for 1/4 mile records etc, they build a dt 100cc that will do 186kph and power wheelie in every gear.

@2stroketerry what was the cylinder originally? 3xp? Does the head have frame mount? I'd be interested in a spare head for my spare brand new 3xp cylinder (nickasil)
Very nice stuff

A friend had a spare 3xp head a while ago will see if still has it for you -
Are you running a supermoto?
I find my 200 scary as the front wheel is hard to Keep down in 1-3 gears.
Any more pictures of your project? What carb will you run? -
Interested in doing a similar thing with the woodruff key on my 125 bore Dt, wonder how big the affects of 4 degree advance are? Much loss in engine life also?
