I asked basicaly the same question as this on the KTM board about my bike and got a great answer from JD.

I have a friend with a 00 WR400. It's stock appart from YZ timing, and he's thinking about removing that.

What's a good starting point to work from for his jetting?

Thanks

Charlie

a good starting point is usually stock. And why in the world you ever even think about going back to WR timing. That would be silly.

Taffy,

Yes he has, but my friend doesn't realy know how to use computers so I thought I'd help him out.

Are you saying for the WR I should start with the same jetting JD recomended for the KTM?

If not can you give me a starting point for just the needle, main and pilot. I have to convince him first it's worth changing, so don't want to spend much money going to your full set up.

get a 40PJ an EMM needle and either a 155MJ for the standard exhaust or a 162 MJ for an open pipe.

it must be tough having no more money than a tenner in his pocket, i could sob for him. could we all have a whipo round.

is he an orphan?

perhaps he sleeps under the stars at night just dreaming of a real bed. :D

don't forget the Taff mod which will cost you 50 aus cents for a block connector (that's one, not the strip of 20).

Taffy :) :D

Taffy,

Thanks for that.

Over here in Australia where the Australian dollar is worth about 3 south pacific shells, the cost of just the needle and main jet is over a tenner. Also taking in to account the lower incomes here, it probably equates to about twice that in buying power.
