I think stock is 13 /38, most people run a 14 in the front for more top end.

Here's something useful that I haven't seen on here yet.

If you are running a dual row Aftermarket rear carrier an bearing..
You can get them at AutoZone:
Your bearing number is: 907257-RS
Just Tell them this bearing number: 907257 it cross's over as a GM Aircompressor bearing.But I do know it will work..

And for the rear carrier bearing seal's: (for stock and Aftermarket)
Go to Advance Auto Part's:
And Tell them this seal number: S-224820 I don't know what it cross's over with. But I do know it will work..

Maybe this will help someone..

400ex carb, maybe play with the gearing to set it up for your riding style and conditions, maybe port and polish and some other head work, but that might run you over your budget

yea i was def. gunna get a 400 carb but anyone no how good a rev box wuld help it?

Why do yall put on 400ex carbs? when is it ideal to put one on? after what mods?

[smr]

400ex carb works real good with a high flow air filter and exhuast. Do some dead work and it will really open things up.

I have some type of aftermarket air filter, but no exhaust yet. If I put a pipe on it, will it need to be rejected if i put a 400ex carb on?
