Motorcycle Engine Servicing

As well as general workshop servicing we also undertake specific engine work. If your bike has developed an unknown noise or fault we can undergo a full diagnostic assessment, source OEM or performance parts.

We also undertake engine tuning and are a supplier of many performance parts. Please see our online shop.

Services include:

• Motorcycle Cylinder/Barrel Repairs and Re-Bores
• Steel Liners
• Nikasil or Plated Cylinders
• Crankshafts

Motorcycle Cylinder Barrel Repairs and Rebore

We offer a few services depending on what type of barrel you have:

Steel Liners and Re-bores

Your cylinder 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.

Nikasil or Plated Cylinders

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. Gauges detonation to the top of the barrel and scores can be welded up and re-plated – this is a considerable saving on a new barrel
