Lambretta Tune, TS1/Monza/Imola, stage RT, labour only, MB

LAB272

This the labour price to tune a standard TS1 cylinder.

Inlet, exhaust, transfers, transfer feeds and boost ports are widened, raised, altered and flowed.

With no welding we regularly see 36bhp with a full race spec pipe.

32bhp with Franspeed and JL4 pipes.

28 - 30bhp with our touring Dev-Tour pipes.

We have even seen 28bhp with our MBgm Clubman exhaust.

This is a mix of our good old stage 1, 2 and 3 tunes which can be uprated to the all round Race-Tour tune and has become our most popular tune.

This can be used with any carb and exhaust

John s on 25 Aug 2013 asked "is any more work needed on this tune if running a 60/110 crank?and what head would you recomend?thanks"

MB Scooters Ltd replied: Same tuning work, ideally you need a decent head, we would use the BGM CNC head. Match and flow the inlet manifold and use a Yamaha block with packer.

Paul d on 10 Aug 2013 asked "does the barrel need to be replated once the tune has been done and does it include modifying the inlet to use bgm/rd reed valves?"

MB Scooters Ltd replied: It depends on the plating, we've done some with no problems and others where the plating flakes. There's different cylinders, the latest ones I believe use the Yamaha style block anyway
