Here is the best value kits 70cc aluminum market. This is the AIRSAL Sport 70cc Ø47,6mm. This cylinder low price does not neglect the quality, 47,6mm diameter high-end aluminum. It has 5 transfers of admission and an exhaust with bar. This cylinder is between the kit 70 cc AIRSAL luxury and 70cc AIRSAL T6 power baths.
Charts are pretty high at admission and low enough to escape making the torquey and not difficult to follow or set. The piston is a mono-segment model with side grease! Clearly this kit has a very good ratio torque / power, it offers plenty of performance while preserving a great strength!
The piston is mono-segment model with chrome domed segment hard, it has side oilers and a light preparation on the rear apron to improve scanning. The finish is really on top.
We advise you to align transfers to lower casings engine.
The cylinder head is a high-compression chamber is incoming to have good alignment chamber / cylinder is 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. It will certainly be less effective than MALOSSI MHR, BIDALOT or Polini ... But there will already very good.
