Here is the 47mm 10 transfers version from BARIKIT, we recognize it well with its exhaust has boosters and all its transfers. You should know that a cast iron kit is more solid on long journeys, so it allows additional reliability but it gives a little less power than an aluminum kit.
This model in diameter Ø47mm in axis of 10mm is a real 68cc! It is a very good high engine, very well finished which will bring much better performance to your machine without compromising on the solidity.
It is of course equipped with a two-segment piston for better torque and sweeping. it has 70 transfers in total, booster exhaust + 7 intake transfers, the sides of the base are well worked. The internal sides are nicely drawn.
In addition it is sold with an aluminum cylinder head for better heat dispersion. In summary this kit will give you very good performance especially at low speed while having excellent strength.
We recommend it with at least: 19mm carburation + 0.30mm valve blades (original pipe, original valves and original valve diffuser can be kept), racing exhaust, reinforced crankshaft and bearings, spark plug cold racing ...
As an option we offer you a stage 1 preparation, this preparation is a modification of the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement to the bottom of the skirt is also included in this modification. Allow a little extra time for this preparation!
