28-5-2015 Buell Xb12 big bore making it, run.

29-5-2015 - Buell S3 Head removal. Buell Xb engine finish rebuild.

Xb12 Bigbore, our own measuring headers on the bike.


Xb12 Bigbore, customer told me big injectors whare mounted... looking at the afv levels way to big for this set up , so took theme out for testing.


Xb12 Bigbore, who almost 20 % more than the stock injectors , a bit over kill for a street bike.


Xb12 Bigbore, checked the stock injectors, these are perfect, will put these in.


Xb12 Bigbore, the bigger injectors also where non directional, while the stock injectors spray directly on the valve , and are directional.


Xb12 Bigbore, still wondering why the engine is so wet from oil , every where ?


Xb12 Bigbore, any way exhaust mounted.


Xb12 Bigbore, battery was already on the charger and kept full, but as i understand the bike was left for 1,5 years... i think it is dead


Xb12 Bigbore, function check... yep every thign works, engine turns over by hand, spark cleaning works so plugs are ok.


Xb12 Bigbore, engine turns over good, but no spark, in the clean spark plug mode the spark plugs work, ( injectors work to, as the bike coughs in the clean spark mode ) so ingnition sensor in on the crank... as it looks like this is also been removed , first i need to drain the case... the oil level in the case is so high, that the oil comes out the sensor hole.


XB9R, long time not seen this bike, one off our first customers, still has the bike, but he moved up to a 1125R, and the lady off the house now rides the XB.


XB9R, front seal , but it has sprong a leak in the front fork.


XB9R, front seal , easy fix, bike supported, and axle out.


XB9R, front seal, and take the fork out.


XB9R, front seal , fork in the support, fromving the top cap and needle.


XB9R, front seal ,cleaned and new seals on ready to assembly the forks again.


XB9R, front seal, bleed the rebound damper before you assembly the fork, as you wil almost never reach the full travel on the damper on the road, left over air will bleed very difficult.


XB9R, front seal , leg back in and front wheel mounted.


XB9R, front seal, noted the spring tensioner was lost... lucky the bracket was not to much damages , as it hit the exhaust bracket it will bend out wards and break the pivot.


XB9R, front seal ,but we have replacement springs.


XB9R, front seal ,little tension on it , and good to go.
