Madass big bore kit "only" 72cc.
The kit consists of:
- Large valve cylinder head 24/20 complete with cam and rockers
- Cylinder 72cc OR BLANK
- Piston kit with pin and rings
- Carb kit with performance filter
- Manifold kit
- Full top end gasket set
Due to the number of different applications this kit fits some will require the fins under the carb to be ground down to clear base of the carb..
We recommend you have a professional fit his kit, However you can use the C50/90 manuals for self assembly.
Changing the standard exhaust is recommended as they are very restricted see our exhaust section for more info.
The get the best performance out of the kit you must run a 22mm 4 stroke carb.
This is a great kit and transforms the lazy 3.4 BHP engine up to 6.5 BHP making the bikes usable for every day use plus you will no longer be a member of the Gutter club!
If you not sure if the kit fits your bike or your not sure about fitting the kit drop us a mail or call our UK work shop +44 (0) 1304 814447 for any advice.
