porting ? on the trx250r

[slamdak8782]

Somebuddy removed the exhuast bridge on my 250r cylinder can I still run it and where are the best places to port and I want a mid to top end 250r any Ideas about how much material to remove from the exhaust ports and maybe some ppics of the boost ports that are ported

If the exhaust bridge has been removed, it will have too wide of a port to support the piston and rings. It would be useless. Unless you resleeve it.

any other opinions on this?

I've heard of people removing the intake bridge, but not the exhaust bridge.

looks like m ebay cylinder is junk then damn

Yea, I was watching that one. You could still resleeve it and use it, but that's kinda pricey compared to other used cylinders out there.
