Motorcycle Cylinder/Barrel Repairs and Re-Bores
We offer a few services depending on what type of barrel you have:
If your barrel has a steel liner it may just need re-boring for the next oversize piston. This can be done easily and we can supply a range of pistons and gasket sets usually from stock including Mitaka, Wossner and Wiseco. We can also fit a new steel liner to your original cylinder if yours is damaged or beyond re-boring. Fitting a steel liner can also be done as a cheaper alternative to re-plating a Nikasil cylinder.

We are able to re-plate your original cylinder back to maufacturer specification and supply a range of pistons and gasket sets usually from stock. Most damage is repairable.
