I have the above engine in my 2016 Znen, badged as a Lambretta Pato 151n here in the UK. I think stateside it's same as a Lance Milan 150
Engine only done 100 mile from new and from what I can make out is a GY6 A and not B but maybe get chance to check once I remove rocker cover and check stud measurements.
Shortly I need to replace the new carb last fitted to try and cure the hard starting issue from cold and stalling at junctions and a erratic tickover as a matter of course I was going to change the plug as well.
Also fitted was a new vacuum pump.
I have checked over the original Denni Japan carb all appears ok with came in the topbox with scooter.
I thought whilst at it would see if anyone who knows these engines made them breath any better and knows the way to go.
Can I
1 remove evap system
2 up jet the carb and to what size
3 remove any restrictions in air box
4 decent aftermarket exhaust system and what sort.
Can't think of anything else off the top of my head
5 this will be the second part as need to change belt at some point soon for the new one
1 What's the best roller weights
2 Clutch springs
