Think my engine is going to die :(

[Paulfzs]

I was going to fit a new bottom end as theres like 5000 on ebay for <£90


but a guy not far from me has an 03 fzs engine with only 23k miles fsh and valves just been done for £250.


for peace of mind i think im going to replace the whole engine, my fzs is currently on its 2nd engine with unknown mileage so the top end may well be almost dead too.
