My 225dx needs the top end rebuilt. I found a good TTR225 top end for a good price. Does anyone know if it will fit/work? If it does is it a performance upgrade? I also found a new cylinder and piston from niche industries (part number 1509) as a stock replacement. https://www.amazon.com/Niche-Industr.../dp/B01LZL04TR. Has anyone heard of this company, I'm not finding many reviews on them. Or should I just bore and rebuild my current cylinder?
Thank you in advance,
Jake.
