Kit 75cc Ø47mm PARMAKIT aluminum air without cylinder head for MBK 51 / av10 motobecane

For those who already have a cylinder head or who prefer to fit another cylinder head than the PARMAKIT such as the radial POLINI for example, we offer the kit without the cylinder head. This kit is a model with 6 transfers, it uses a special system to feed the rear sides. Its diameter is 47mm.

We greatly prefer it to the AIRSAL model for example because it has 6 real transfers but also higher diagrams! This kit will be ideal for driving every day outside France because it does not work very much in terms of light shapes and diagrams, which makes it solid but also very torquey. Preparers will also greatly appreciate working this kit in their own way. The nykasil is of very good quality and the workmanship is excellent. The exhaust is a banal oval model.

This cylinder has a decompressor outlet that you can use if you wish. The piston is a chrome S10 mono-segment, it has 2 side grease nipples. The transfers being worked and enlarged, we recommend an alignment or POLINI, BIDALOT housings… to accompany this kit! To conclude, this stock cylinder will be extremely torquey but will preserve more power than an airsal for example! He is very solid and can be transformed into a real performance monster by a good trainer.

We recommend to accompany this kit at least : 17.5 PHBG carburetor, reinforced crankshaft and bearings, original prepared crankcases or racing crankcases, expansion exhaust, large diameter cylinder head ...

The pack contains :

X1 Ø47mm cylinder 6 nykasil aluminum transfers
X1 single segment piston with lateral grease nipples
X2 piston clips in G
X1 piston pin Ø13mm
X1 reinforced cylinder head gasket
X1 base gasket
X1 reinforced exhaust gasket
X1 assembly instructions

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!
