Here is a rather exceptional kit from the Italian house PARMAKIT. Indeed, with its diameter of 55mm and crankshaft stroke of 40mm!
It takes an architecture based on the 110cc of the same brand.This 95cc serras obviously based higher speed than the 110cc and above all much easier to operate, plus it does not require machining for its passage.
This model unlike the 110cc does not require specific machining to pass the cylinder into the housings. It will however align the casings which is a lot of work.
With the 40mm stroke provided for this cylinder, less grip for the passage of the crankshaft. The cylinder was very worked, 5 transfers of admission are present, only one for the back (we all know that the transfer is used almost only with the activation valves and the scan ...), the side are therefore at number of 4 and they are very bulky, increased on the lower front like most hyper racing cylinder of great brand.
Exhaust level, PARMAKIT has opted for the booster exhaust is the most suitable for the couple of the beast, a big exhaust booster very well drawn is on this cylinder.
The piston is a true vertex in mono segment end (1mm) to fully release the high speed. It is a low crown piston. For the cylinder head, it is necessary to extract the heat of this thermal group PARMAKIT has therefore opted for a cylinder head.
The breech block machined in the high-end aluminum mass, the chamber is a model very well adapted to the piston / cylinder, its shape is hemispherical polished finish, we regret that the stud is not entering to keep aligned the chamber with the cylinder, the pose of pieces is always possible.
The cylinder head cover is also very well studied and has excellent maintenance! In short ... We could spend hours talking about this pretty monster that we released the great PARMAKIT, this kit has really been neat up to the comma skirt for the improvement of filling ... The whole is really a whole quality, neat, great study.
We recommend this kit with: crankshaft reinforced stroke 40mm axis 12mm, carburizing 28mm minimum and quality with valves / pipe ... Reinforced bearings, good cooling, complete preparation, efficient ignition, well reinforced clutch, cold candle, racing exhaust ...

Optionally we offer a stage 1 preparation, this preparation is a modification of the exhaust port by increasing the diagrams and improving the pipe, it increases the performance of the cylinder. An improvement of the bottom of skirt is also included in this modification. Allow a little extra time for this preparation!
