If a Blaster needs + 6-7 for simular mod, start +8 sizes ond work down. Must be used otherwise would think you'd have some instructions with it. Have you considered looking on a YZ forum :-/. Might have to bump the pilot too.

I could be wrong too, that pipe may be less improvement if stock Yz is good , compared to a chitty Blasturd pipe

Go to e2s they will hook you up

If your yz has a mikuni carb it should take the same jets. do you have any spares from your blaster?
