Top end mods

[Shagbark]

For those who build or have had builders mod your saws:

Is it advisable to send a new oem P&C to a builder for their standard performance mods and assemble and tune yourself? Is it wiser to send them the whole saw?

You prob know the answer based on your wording.

Gotcha Fellas. Do it once, right, or don't do it at all.

Thanks

What saw?

The only time I will do one without the whole saw is if it's an over seas customer that really knows what he's doing, in order to check necessary clearance upon installation.

Any or all of the 3 in my sig line. I have a new oem 390xp top end and a new oem 346xp ne top end sitting in my inventory for the next step. All my saws run great and don't need reworked, I am just OCD.

I suppose it depends on the type of mod being done. If nothing else needs modded to match the p/c work then it's just plug and play like any other stock kit you buy online it from a local dealer. Your only obstacle would be tuning the carb.
As Brad mentioned above...anything beyond just port work and you're gonna need the case for clearance measurements. Every cylinder is a little different from casting imperfections and multiple molds. The biggest differences seem to be the squish band.
