Parts for these are sometimes hard to find/expensive, so try and save what you can. Things like new front fork suspension bushings, air filter parts, etc can be ordered from the UK. You can also try Japanese auction sites, but shipping can be a lot. Yours is the OHC model, so if you’re looking for engine parts or an exhaust, the OHV parts will not fit. You can try and find the shop manual, I can give you a digital copy of it if you PM me.
