Arrow white large caliper earth oil



Two of the 50 or so chemicals to be found in modern pump petrol.


Ethanol is a fuel with a high octane rating - 113 instead of the low 90's petrol can offer.  Isopropyl Alcohol is added to prevent fuel icing.


All looks good so far, but there's a catch ....


They are both water soluble meaning they absorb water from the atmosphere, then dump it in your fuel tank and carbs.


It is impossible to clean every little drilling and airway inside a carb by hand ... it doesn't work.




Our service includes a full strip, sonic clean and rebuild to standard settings.  We will also repair your carbs if necessary and set your float height and mixture screw before returning to you with an information leaflet about re-fitting your carbs.

Genuine S3 400 in for some rechroming and investigation into bad running and strange engine noise. Top end coming off on Monday morning

Motorcycle MOT Bay 025

S3 400 all ready to go after a complete engine rebuild. The bad running problem turned out to be a melted engine due to poorly set  up carbs and timing. Rebore, rebuilt crank, new pistons etc. You really do have to know these bikes to get them right.
