No, I have not. Have never heard of such a thing. What is the cost?

roughly $35 AUD off the top of my head i think they are, just researching and it looks like a common mod for the blaster in the USA,
%99 sure that it will fit, just not sure how the CDI will handle as i have also read that the Aus DT200r CDI sets timing @ 0 degree on start up then retards to 20 odd deg or something like that after start up..
my thoughts are.... will the +4 keyway mess with start up ignition timing
Have seen many many blaster 200 mod install vids on the 4+ advance, Just wondering if this would work with the Australian DT200r 1988-1998
Any and all ideas? thoughts on the subject much appreciated
cheers

Pretty sure that 98 DT200 and blaster only share capacity in common. different everything else.

Can?t you just advance your timing? You might not like it, I?ve played around a bit with a YZ, I like stock on most things, but it is fun seeing what the difference is.

i have seen a couple of vids online showing how to "machine" out the holes in the stator plate so it can be rotated slightly for adjustment, but it looks a little dodgy to me, thats why im looking into the +4 degree flywheel keyway, as 88-98 3et DT200r have no adjustment

That sounds like a hard way to gain a small amount. But, I'm not sure on what gains you are after? Here is Yamaha's take on the DT200R's ignition timing.

hi glenngt750,
this is exactly the sort of info i need, Cheers m8, yes machining the stator plate would be the hard way, thats why im looking at using a VITO's +4 deg keyway for flywheel instead, much much easier install and no guess work..  i had read that the dt200r starts @ 0deg then retards to 20 or so once started, from the looks of that yamaha timing map you have posted that 0deg to 20deg is FALSE, so my thinking is +4 deg @ startup will not hurt.. Which is what i was questioning and you Glenn have answered that for me, Cheers
cars and bikes of yesteryear ran such retarded timing because of lower octane fuel, a lot of us run 98 octane nowdays ... Why not make the most of the higher octane.To any nay sayers. Im not doing this for HP, im after response... I have been playing with holdens for 18 years for the last 6 i have been playing with a HSV 5litre, which from factory is tuned for 98ron only, as such it has more advance than a holden 5litre... why wouldn't advancing timing on the dt200r work ?? ive done it with stationary pump motors and cars, never any of my bikes tho the dt will be the first, 
Cheers for the input
