I have personal feedback on an ESR 350p/v cylinder. It ran real well, tons of low end and would hook up great on the track. You will have to get your bottom end cases machined out to accept the larger cylinder. I never ended having the cylinder ported before I sold my quad but I was originally planning on sending the cylinder to Neil at C-Leigh Racing to clean up the ports and make it focused for my riding style. If it was me buying one new, I would buy a blank Pro-X cylinder from ESR and send it to a more detailed machinest like C Leigh to get a better port/polish. A lot of the bigger companies port jobs are not bad but their not great either, their more of a generic port.
