Break in / Plug chop Question?

[LOCSTA]

I just got the rest of the parts I need to rebuild the top end and replace my reeds. Once its done and I've done a leakdown test and there are no leaks what do I do first. :-/

Break in, or plug chops so I dont run it lean?

It seems if I do the plug chops first I could harm the top end because it hasnt been broken in and I have to hit full throttle in 6th. But if I dont do the plug chops first, I could be running lean durring the break in.

Please help. I dont want to rebuild again for a while and it would really suck to fry the top end again.

Thanks in advance.

You're going to have to guesstimate what jetting to use, break it in and then do a plug chop. I would guess around a 250 main jet to start with maybe richer just to be safe.

Thanks for the info bro. I wasnt sure how to go about it.

what carb/settings and mods you running ????,
and a main jet shouldn't have anything to do with the break-in heat cycles, that require no more than some light half throttle revs every 30 seconds or so till fully warmed up, then allow to totally cool, repeat 5 times, retorque/recheck head and base bolts,
then grip it and rip it for plug chops

I got new rings, gaskets, vforce reeds, and a powercore 2 silencer. I dont know what jet is in it but I'm planning on using a 280. Does that sound right?

270/280/290 should be close
