Caution, do not respect the required displacement, for competition on the track, road closed ... run!
Here the kit 80cc single-luxury segment of the Spanish house AIRSAL, this kit is also available in two-segment of 154 euros with us! This kit has certainly a cheap yet a good quality and present performance. Its diameter of 50mm still offers real 76,57cc combination of normal stroke of the engine so 39mm ICC. In relation to the two-segment model, it will offer more high speeds (it feels barely) and obviously less strength and less torque, the piston of the other model is a bi-VERTEX segment, it is also VERTEX but a single segment with side grease.
The diagrams have a good ratio torque / high speed (around 187/131/130 °), coupled to this large diameter 50mm we recommend this cylinder with a good configuration anyway! A good racing exhaust, a 24mm minimum carburetion to operate well, a crankshaft and bearings reinforced ... The finish is really good for such a price.
The piston is a model mono segment with chrome domed segment hard, it has side oilers. The cylinder head is a high-compression chamber is incoming to have good alignment chamber / cylinder and a good performance head gaskets. The room is a polished hemispheric model. This cylinder head allows you to reconnect if desired antifreeze on your carburetor.
This cylinder comes with 2 joints of base plate to put the desired squish. Clearly this cylinder is really a superb quality / price / performance ratio! It will be certainly less effective than MALOSSI MHR, BIDALOT, or POLINI because its distribution, its canals, the study, the venturi exhaust ... are relatively limited, it is a al'identique nykasil scanimet, has the incomparable nykasil hard ceramic or plasma! But there will already very efficient, especially for those who do not want a kit complex and difficult to talk. A good trainer will also draw quite astounding performance.
We recommend at least: 24mm carburetor with prepa boite a air + slices valves 0.30mm / 0.35mm, exhaust racing pot, crankshaft and bearings reinforced, cold candle racing ...
The pack contains:
Fitting with washer for taking anti gel
Pack complete joint with 2 base gaskets for the squish
Racing aluminum cylinder 5 exhaust transfers has bar
VERTEX piston mono-segment
Chrome domed segment
notice
