DT400B delivered from All-American-Imports yesterday, very pleased. Great service, cheap delivery and a very honest machine. Just need to get it running now.

Few questions:
1. The reeds look like the original stainless type and in good condition. Is there any good reason to change these for a more modern reed material? I'm not after any more performance, just a smooth running engine.
2. Spark plug listed is an NGK B8ES. Any better plug?
3. Are there any ignition coil upgrades for a fatter spark?

Thanks.

Nick.

Lovely jubbly, as we say on this side of the pond!

The folks here will chime in with answers, I'm sure.

All I would say is that the pulsers for the cdi on your 400 and my 360 (I believe that they share the same part), were never the most reliable. In fact (certainly on the 360), a lot of owners converted the bikes to a points ignition system.

I won't bore you with all the details, but I thought that a previous owner of my 360 had been arsing with the wiring or even sold off some cdi parts for spares. It was only after I'd spent a small fortune getting replacement parts that it dawned on me that it had been converted to points!

One more thing that I've just thought of.

There should be a de-compressor on your bike, linked to the kick start. If it's the same as my DT360, there should be a cable running from where the tacho cable sits in the crankcase to just above where the exhaust bolts on to the barrel. It is the valve itself just above the exhaust and may or may not be protected by a rubber boot!

Slide the cover up the cable and then gently press on the kick start by hand - you should see the cable open and close the valve in sync with the kick start. Like all cables, it can be adjusted either way if necessary.

Regards.

Alan

Looks great, congratulations! Out of curiosity, where is it imported from? Seems to be in great condition.

Yes, I’ve seen that cable Alan, seems odd that it’s needed. Mine is seized closed so that’s another job on the list.

It’s a Californian import. Very clean and tight.

I believe that they might give a nasty kick back otherwise. The RT2 and RT3 have manual levers for the decompression valve, with a sticker on the petrol tank warning you not to forget to use it!

The one off my RT2 unscrewed from the barrel easily enough and I hope yours does too.

I don't believe so.

The DT1/2/3s are 250cc and it was only the 360 and 400cc bikes that have them.
