Here is the latest from AIRSAL! The Spanish brand is launched in a superb challenge, to release a high ultra racing engine, very powerful in an unbeatable price. Successful bet as proof with this high real AIRSAL Xtrem 78.5cc Ø50mm red engine. This model is really beautiful, powerful and ingenious, all for a very reasonable price.
The cylinder is therefore a Ø50mm, it is mounted with an original race crankshaft. This cylinder is not only painted red, it is an entire architecture that has been created! The rear admission receives 3 transfers in order to improve the sweep, the lateral ones are 2 in number and they are well worked overall. The exhaust is a very large bar model. Nykasil is a trivial scanimet (we will still prefer a high-end coating like hard nykasil but it is already of good quality). We can classify the cylinder as the entry level of hyper racing.
The diagrams are high in order to offer maximum performance at high revs. The cylinder head is an ordinary one-piece, we would still have preferred a stud bolt to improve cooling and changes in volumes, shapes… But this cylinder head monobloc will already amply satisfy 99% of users! The chamber is a high compression hemispherical model with a polished finish.
The piston is in the form of the ordinary VERTEX model that is often found on AIRSALs, it is of very good quality and it is specific by a treatment on the anti-detonation cap. The piston is equipped with side grease nipples which is also very appreciable for longevity. The attached pack is complete but you will still lack base gaskets to make the squish as it should be which is regrettable!
To conclude, this set is really superb value for money! The performances will be there for sure with such a high engine. It is clear that users who really want very polished material will regret the absence of solid studs with nuts, a hard nykasil, a stud bolt, gaskets to make the squish correctly, ...
But for such a price we couldn't expect anything better than what AIRSAL did! The finish will certainly amaze you! It is worthy of the greatest BIDALOT, MHR ... See even better!
We recommend with this kit at least: Ø28mm carburetion, reinforced crankshaft original stroke 39.2mm, reinforced bearings, suitable exhaust, low engine / high engine alignment, ignition according to the revs, cold spark plug grade B10 (31 in DENSO) see B105 ( 34 in DENSO), ...

As an option we offer you a stage 1 preparation, this preparation is a modification of the channels and the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder.
