Hey Guys,

I'm rebuilding a 2004 Blaster, the prev owner had the Vito's top-end kit, but never rejetted it and well you know the rest of that story!

so i've rebuilt it with the following specs..

- Stock Piston and jug
- vForce 3 Reeds (came with them!)
- Pro circuit Expansion chamber
- Unknown muffler (my buddy beleves its the pro circuit muffler)
- Air Filter is one of those cheap paper looking ones you get from Ebay (large oval at the top, small oval at the bottom, blue filter)
- No Airbox Lid
- Oklahoma Elevation (4,973 ft according to google)

so, the carb appears to have stock main jet (230) and im wondering what jetting would be correct for this build, any advice is greatly appreciated!

i dont have an exact answer for you but it was i am assuming lean before and that is why you rebuilt it again. if it was me i would get the dynojet kit, they are under 50 bucks and have everything you need including instructions that cover your mods and elevation. the other plus is if you ever travel with it you will have the jets to make it work from sea level on up. i also like the change in the fuel curve you get with the dynojet needles. i am not much of a 2 smoke guy but i have buddies that will rejet anything over a 1000 feet in elevation, that is a little extreme for me but rejetting is just part of 2 stroke life. i did a quick look at the dynojet instructions for a blaster and they said a dj 350 or 360 for your elevation and mods but that is a model number not a jet size. so that is not much help. if you dont want to do the kit my best guess is go up 1 on the pilot start with a 250 main and 2 turns out on the air mix and the needle in the middle. run it for a short while and check the plug. if it is black go a little leaner, brown leave it alone, white go a little richer. do this until you like it.

as a side note i put a jd jet kit or dynojet kit in everything i have. it just makes life easy.

i will look into that, jetting has never been a strong suit for me, so anything with a cheat sheet helps!
Thank you!
