Buy the hard cover book.
Obviously it's no 350Kmh road racing monster.
Run it in as per the manufacturers instructions.
Olive Oil is fine to run your engine in on, provided you change it regularly. like every 300 - 500Km.
And you use the bike as a daily commute....
But if your around town speed, is say 60Kmh (40 MPH), where you will be spending most of your time at, this is where you want the best breathing and the most power to be at - the most amount of power for the least amount of fuel.
Set up three things.
write down the rpm at this sign posted speed. does it have much hard pull beyond this speed? And after the proper run in period, or determine the top speed as per manual / rpm limit.
This is going to give you an idea of where to best to tune for maximum potential power, relative to the natural characteristics of the engine
Make a tuned length exhaust pipe - about 40 cm longer than the straight pipe in your exhaust.
Bend it and fit it.
Find the jets that fit the carburettor, buy about 4 of them, in increments of one size larger than stock.
Find the adjustment range of the needle
Figure out how to tune the engine to run rich, by going up 2 jet sizes lift the neddle 2 notches and fit a high volume of air flowing oiled foam.
A tuned length straight pipe exhaust has a resonant frequency, cut off say 20mm at a time until the motor pulls it's hardest at 60Km - and this peak starts at say 50Kmh and fades out at say 70Kmh...
Find or fit or make a suitable silencer - allow and adjust for the extra length, then tune in the carburettor... by the spark plug colour method - light tan to slightly brown.
Like I said - buy the book.
