Lambretta Cylinder kit, RT225/230, Reed tuned with MB Shorty Reed assembly, PHBH, Race-Tour MBgm
PLEASE NOTE THESE ARE TUNED TO ORDER AND MAY TAKE A FEW WEEKS BEFORE DISPATCHING
MB Reed Tuned Race-Tour package, the same as the popular piston port version but with all the added improvemnts of having a Reed valve tune and Reed assembly.
MBgm Race-Tour 225 cylinder kit using the new Reed cast coated MBgm 70mm piston. Touring reed valve tuned, with Reed assembly to suit a Dellorto PHBH 26, 28, 30mm carb.
The reed tune transforms a piston ported RT cylinder, lifting power across the rev range making a smoother more powerful engine. You need less revs to set off, tickover and jetting is improved as is fuel economy.
This is what is involved
- Inlet manifold bolted to the cylinder and perfectly match, flowed and polish to the inlet port
- Inlet port is matched, opened and flowed to work with the reed assembly
- A boost port is cut above the inlet port
- Exhaust ports are reworked to suit 58/60mm crankshafts
- Transfers are altered as they go into the cylinder and flowed
- Transfer feeds are flowed
- Cylinder is light honed afterwards
- Cylinder is ultra sonic cleaned
- Piston to bore clearance is matched
