+===== History Timeline =====
-  * January 28th, 2008  Mugen Seiki announces a new [[ninjajx|Ninja JX]] line in partnership with OS Engines.
+  * Mid 2009  Forums reported JP Racing closed down due to Jean-Paul wanting to retire.
-  * February 1st, 2008 [[grpgandini|GRP Gandini]] announces that it has ceased production of MR NINJA engines for Mugen Seiki.
+  * February 10th, 2010 Jean-Paul Calandreau teams up with GI-MAR and releases a line of engines and pipes under JP GI-MAR.

 Recognizable to their black crankcases, the JP Black Engines are at the top of the world performances and through several ingredients:
 - The excellent connections between Novarossi and JP Racing companies.
 - The knowledge of Jean-Paul CALANDREAU’s long experience in mechanical science enabled him to develop and improve many tips to increase racing engine's performances.
 - The engine parts are meticulously prepared and perfectly assembled.

+JP Black Engines Modifications...... Often copied, never equaled !
-Recognizable to their black crankcases, the JP Black Engines are at the top of the world performances and through several ingredients:
+Every engine is carefully assembled. The bearings are precisely aligned and checked. The crankshaft is adjusted to the two bearings in order to obtain a free rotation. The piston-sleeve set is assembled on the best in the crankcase and the engine decompression is adjusted to the recommended fuel. Every engine is tested in compression in order to reach an optimum output since the end of the running-in.
+- Black Crankcase
+After undergone modification of its ports and their alignment with the sleeve, the crankcase is treated black in order to improve the heat dispelling. The decrease of temperature of the engine enables a better output and a lower consumption. With this treatment the crankcase’s oxidation is avoided, the bearing site and the crankshaft’s passage have better hardness.
-- The excellent connections between Novarossi and JP Racing companies.
+- Lightened and Treated Crankshaft
+With the great effort, the crankshaft is lightened to reduce its inertia. The designed hole is filled with a special dough which improves the gas flow and decreases the crankshaft vibration at high speed and reliability bearings.. The crankshaft’s timing and shape are optimize the gas flow and balance by means of modification. To provide high reliability to this important engine part, the crankshaft (especially its pin) get HardBlack coating which has a hardness close to the diamond’s and a friction coefficient similar to the Teflon’s. This treatment ensures higher RPM without any loss to the connecting rod.
-- The knowledge of Jean-Paul CALANDREAU’s long experience in mechanical science enabled him to develop and improve many tips to increase racing engine's performances.
+- Modified Piston-Sleeve Set
+The sleeve ports are modified and aligned with this crankcase. The piston is adjusted to the sleeve in order to obtain an optimum compression and better performances after the running.
-- The engine parts are meticulously prepared and perfectly assembled.
+- OPTION Ceramic Bearings
-===== Eagle Stock =====
+The JP Engine's rear bearing can be mounted with ceramic balls (except in the Stock Version engines). allow very high RPM. Due to the low density of the ceramic balls, the pressure on the cages is minimum and won't slows down the rotation of the mowing parts when RPM are increasing. The longevity of ceramic bearing’s is better than normal bearing’s. Recommended for high-level competition.
-===== Eagle Black =====
+- OPTION Pre-running-in
-Recognizable to their black crankcases, the JP Black Engines are at the top of the world performances and through several ingredients:
+The pre-running is manipulated by Jean-Paul Calandreau. It is an additionial guarantee of performance and longevity of the engine. You are most WELCOME for T-Rod option!
-- The excellent connections between Novarossi and JP Racing companies.
+- OPTION - R6 CONROD (light)
+The R6 is the most performant of the current conrods designed for the different JP21 engines. The brass ring on the piston side has been taken away to lighten it, for better performances. It must be used with the special HardBlack treated wrist pin. The coating limits the frictions and avoids the micro-scratches. The R6 connecting rod is used for more bottom power, better acceleration, and engine moving parts reliability.
