I have an ESR310 cylinder, dome (I believe pump gas) and head that I am thinking about selling.  I decided I may put the money towards my suspension upgrades instead of engine at this time.  It is still on the 72mm bore and has C7 engraved onto it below the exhaust port.  It needs a piston and water neck.   Can anyone give me an idea of what it is worth?

Consider a new 310 kit from ESR is $599. $699 with TRX7 porting. Yours needs a piston ($200 with gaskets) water neck ($25). Now yours might need to be honed or bored the next size. So I'm going to guess $150-200 range.
87 trx250r- ESR 310 (trx9 porting) trx5 pipe, 38mm A/S, +2 a-arms. works triple rates.
86 trx250r- basically stock (SOLD)
05 Predator 500- some bolt on stuff
87 Tecate4- new project

It was honed before it was sent to me.  If its worth less than 200.00 I'll just put it on the shelf until I am ready to install it.

Yeah i'd say $300 tops....but even then, i'd say keep it.
I ride PINNED! Therefore, no bdt in this household.

Just to verify, does C7 indicate TRX7 Porting or the Port Match 7?   I'm guess Port Match 7 as it is not as smooth as I would of thought it would be.
