Hi. The new trx90 oil pump part number is 15100-GBG-931
As for the c70 big valve heads, depends what piston you fit, as it will make a lot of heat and cause issues,
I've moved away from them as camshaft options are not to good compared to the later roller bearing heads.

Thanks for the information Alan,
I would like to stick to genuine Honda parts if possible and I would like like to start with an engine that has not been messed up
what heads and camshafts are you using now?

[Alan CF]

Late roller bearing heads, with 1mm bigger valves
As there's more camshaft options available.
