The second tip is not to use synthetic oil for running in. "It won't just slow the running in process, it ruins it - do 20 miles (32km) for new on synthetic and the engine'll need stripping." the bores and bearing surfaces end up polished and unable to hold a film of oil. the same thing happens when you run engines in too carefully
Most engine wear occurs in the few seconds after starting from cold. The oil is thicker can can't circulate, and while the bike was parked all the oil drained away from the top end of the engine. You can help circulation by cranking the starter for a few seconds wifh the kill switch off.
Particularly it's about these 2pts whereby I have done running for the litre bike bought recently but using fully synthetic oils provided free as a maintenance package for 3x @diff mileage... any permanent damage done (as this is my first litre bike or rather 4 stroker ; from 2b-2) but didn't run in 'too carefully' though.
Next is about cold starting... understand that most equip wif auto choke but still...til now requires several push on the start button...bike does nothiing wif the kill switch off... got any other alternatives? Really need some guidance ... thanks
