Congratulations!  Fingers crossed it runs great now. 

(Also wondering if ignition contributed to or even created reason(s) you got away from MX cylinder?)

Nope. 
Started nice on choke, idled nice, ran and idled without choke for a few seconds. 
Then died.
Restarted and repeated for a few seconds.
Then took a couple of extre prods to start was fluffy, died and back fired.

I am presuming, from my process of elimination that the issue lies on the magneto coils / pulsar.

What do you think?

I'm thinking that as the ignition system warms its now exposing the problem. Plus could the issue at source (magneto coils / pulsar) be scrambling the cdi? and could the scrambled cdi be burning out coils?

Wish I had the answer!  Those systems run on "black magic" as far as I can tell? 

If it were mine and I wanted to keep the very low inertia inner rotor flywheel, I'd buy a new ignition system from HPI.  www.hpi.be/item.php?item=068K456

A little bit of flywheel weight is not a bad thing...  easier to start and will improve acceleration on a powerful dirt bike by keeping wheelspin down...  so I would probably use a points magneto off an Enduro if it were mine. 

 

I'm guessing that you're in the US? A shame, as I have a complete DT360A stator plate, pulsar etc on UK fleabay.

I haven't run my bike with the cdi, as I bought it before I realised my bike had been converted to points! However, it bench tests within spec.

Hi, no I'm UK. Can you provide a Link?

Hey Mark,

No I get it re flywheel - however I've been chasing shadows with this bike for so long, that I want it just to run relaibly for a while beofre I start something major.
On the HPI site, I cannot see anything listed for RT2 - which system would you say look for DT360?

Or maybe something wrong with link..  Let me check.

Somehow "6" got dropped off the end.  Sorry.  Above should work better.
