New Pipe and Open Air filter.... Jetting help.

[jsmay]

Ok, so I've been search a little here and there for an old school pipe.. well i found a good deal on a full Kerker exhaust...and I've been waiting to switch over to an open air filter like shortline10 has on his x's/... so now I've got the exhaust and gonna order the filter... but what jet size should i go up to? I have the stock carb for now...probably switch to a xr200 w/ xr200r intake at some point but for now its the stock carb. I know its gonna breath a lot better now, I just want to make sure its drinkin proper!

thanks guys, I know somebody has experience with this.
