Engine blueprinting is the process of setting every tolerance in the engine to its optimum value. Engines from the production line are often quite “baggy” with gear changes feeling notchy from incorrect shimming, vibration from poorly balanced cranks, rough low speed running from valve clearances being too large - generally speaking the performance of an engine can be improved dramatically.  After blueprinting and very fine crank balancing, gear changes will feel more positive and vibrations will be virtually eradicated, reducing strain on the engine, aiding longevity. Valves will seal correctly, piston to head clearance (squish) will be optimised and cams will be finely timed bringing your bike’s performance right up to scratch.

You get ... All components cleaned de-carbonised and inspected, clean sludge from crank, polish journals, plastigauge crank journal and fit with the correct specification bearings, shim crank, primary, secondary shafts and selector drum, check piston ring end gap, set squish, hone cylinders, lap valves, set valve clearances, dial cams to specs, check piston to valve clearance when fitting cams big and  valves. NOTE valve clearances are set to a tighter spec of shimming meaning clearances do not need maintenance for a very long time afterwards.

Performance parts such as pistons, big bore kits, cams etc, supplied by the customer or through CJS can be fitted free whilst your engine is being blueprinted or having a super set-up.  Customer supplied parts must be cleared for quality by CJS first.

Cylinder Head Optimisation

Cylinder heads are optimised by flow bench using the latest digital software. See Cylinder Head Prep pages and related articles "The Flow Bench" and "Power in the Head".

Cost Effective Modifications

Through experience CJS knows that each engine has its own little area where cost effective modifications can be applied.  These include optional cam settings, re-shaping ports and combustion chambers.  Some Ducati cylinder heads can be sufficiently milled to give a substantial increase in compression ratio and power without purchasing expensive pistons (see 916 projects page).  Whilst blueprinting your engine these cost effective modifications can be provided at extra cost. This can be discussed during your initial consultation on specification requirements.
