Bonneville "Bunn" Breather kit
Ł89.00
The 2010 Bunn Breather is the only motorcycle crankcase breather designed to actively pump out accumulating moisture and sump water. This makes it perhaps the ideal motorcycle breather for its time, given the march of ethanol fuels.UPDATE:"The kit has been 'uprated' so the air filter was replaced with the more compact nylon filter housing The Bunn Classic Breather Kit manages the crankcase pressure and airflow.It stops pressure swings,cuts oil leaks and power loss.The breather is designed to do three things: cut crankcase air pressure and oil leaks, actively pump blow-by vapour from the engine, and reduce power losses due windage, oil drag. It is designed to assist engine function creating more efficiency and increased power .

Graphogen 50gram tube
~~Ł24.50~~ Ł19.99 On Sale!
What is Graphogen? Graphogen Assembly Compound is a colloidal graphite paste in oil and gives protection and peace of mind when running in all types of precision built machinery. Due to the high content of graphite in the compound, the paste is black in colour. The very low co-efficient of friction far outweighs the appearance. Graphogen provides an excellent safeguard against the potential rubbing or scuffing of metal components and is the first line in protection until the oil pressure is obtained.

Graphogen Paste
Ł6.00
Graphogen Assembly Compound is a Colloidal Graphite paste in mineral oil and is used during assembly. All internal surfaces of machine parts - especially cylinder walls, pistons, and piston rings, main bearings, valve stems etc – are coated with a liberal layer of Graphogen. The paste is applied with a clean finger or brush, without being diluted. It will not run off treated parts whilst in storage and all internal treated parts are protected right from the start by a Graphogen layer of concentrated colloidal graphite. This will create a lasting skin which is self lubricating and retains the oil under difficult conditions. Sold in 10 gram sachets. (That's enough for one full Bonneville engine rebuild).
