DT1 IGNITION SYSTEM

[jimson]

G'day viewers I need some advice on my DT1 250 ignition system. I've spoke to blokes in the past but my head is a seive and can't keep information anyways I have a DT400 with a CDI system on it but if I use that the  bike is useless. I've bought a ignition system from the local wrecker off a early 80s YZ80 because I thought that was the way to go but how do I fit this system to the DT1        jimson

where you say

i'm guessing you've got the stator,flywheel & cdi box? from a YZ80.
i'd be looking for something with a little more flywheel weight {1550~ish grams=perfect} aiming for "torque" instead of revs.
early DT's, really are a good choice for the DT/RT1 motors as they bolt straight in.
if you proceed with the YZ80 set~up,
you'll need a lathe or someone that can drive one.
fit the stator plate first {you may need to machine up an adapter plate},
then you'll know what needs to be machined off the flywheel to make it fit.
it's a bit of rooting around but can be a heap cheaper than a PVL by comparison.

DT400 CDI onto DT1 race bike.
DT1 points onto DT400.
Problem solved.

Oh, and what Vandy said.

I did my pre70 RT1 on the real cheap. and it doesn't show..Parts used- 12v alarm battery[the only part I bought], Old 12v car ign. coil, the small type fits under the tank in the original spot, condenser off who knows what,. I mounted the battery under the seat. the battery will easily do a full days racing. The spark would kill a black dog which makes it start easier and kicks back less, probably because of better flame travel. If I desired a charging system I'd get a coil of an old 6volt VW beetle and find a diode. I read in an old Clymer book once that 'for racing Yamaha motor cycles the ignition system is unsuitable as standard'.
