One of my friends got his bike out of storage, and didnt warm up the bike and drained the oil and pulled the filter out and drained the oil out of it too.But he didnt warm up the bike before and let the oil drain for 15-20 mins and then filled it up with synthetic.(Had cheap cambodian tire oil before.). He used the same filter too as it was a new one just for storage.
Does this damage the bike anyhow.Just trying to help some1 before he messes up something big.
Personally i dont think it makes much of a diff tho.
But would like comments from the techies.
