Mine is 85% of the way complete.
The videos you posted are the DT200R (3ET) engine in a blaster, it uses case reed induction and isn't quite as powerful as the 37F used in the 84-88 DT200's sold in Canada and up to 99 in some areas of south America. This swap is a PITA, because lots of the country's that do have a multitude of these motors have extreme shipping, and taxes you have to pay. Best places to look are Costa Rica(tons of them), Greece, and Canada. I've got 2 of everything and if I don't lose motivation maybe w/ the help of a friend who is an electrical engineer and Zeeltronic I will bypass much of the problems w/ the stock CDI. Zeeltronic is a programmable ignition and powervalve motor controller used by some banshee owners w/ the RZ swap. It's pretty awesome, allows you to change all types of variables.
To do the swap you need:
Machined clutch basket from DT200R, Side case, water pump, primary drive gear, and DT waterpump gears
Or Blaster gears w/ modified custom made waterpump driven gear to mesh with the teeth of the primary drive gear from the blaster
or if you can find them, get the impeller gear from a RD125L/C sold in Asia and the waterpump driven gear from a DT125L/C MK1 sold in UK and mesh it up.
Or one more option, run the DT basket, side case, primary drive gear, and transmission in the stock case
Other parts needed:
Powervalve control box
Powervalve servo motor
CDI
Voltage rectifier regular
Wiring harness
Battery
Fuse holder
Flywheel
Stator
Powervalve it's self
Radiator
Cylinder head
Cylinder
Cylinder head gasket(extremely hard to find)
Powervalve seals, and O-rings(unless you find a mint cylinder)
OR you could just get the DT200 engine and drill out the back of it as Macdizzy did and add new bushings so it fits, but remember, these were enduro bikes(capable of speeds of 112mph in the later 37f models sold in South America) and wouldn't be prime for use in an atv...
It's alot of work and not discouraging anyone from trying it, but I just wanted to do it pretty bad and went for it. I kinda wish I would have just gotten a 3mm crank and an CT set-up.. but in the end it will be worth it.
One more thing to remember, these engines are known to overheat, so you need to have 3 spare impellers and water pump seals on hand. Good radiator to use is one from an RZ350 w/ a fan wired in of some sort.
Good swap, and lots of potential, but unless your committed and willing to spend countless hrs searching/calling for the parts, then it's best to swap a YZ Tri-Z, or build up the aircooled platform.
Continue thread... Pics will come don't worry, I will update my thread in a few wks, this time I mean it.
