i found a dirtbike, and i brought it back home, and i found out that there was no sparkplug in it for however long it was sitting for. when i took the head of the engine block, there was some rust in the cylinder. will i have to bore out the rust and buy a new piston? It is a really nice bike, compared to my other bikes :P. any help will be appreciated.
it is some kinda yamaha. it has a mono rear shock that goes all the way from the back axle up to the handle bars, it is huge. it has air nozzel ajustable front shocks aswell. i think is it a 300-400cc dirtbike. because the carb is bigger than the one on my 250. i dont kno whow to hook up the cdi and the sparkplug coil... and there is no piston.
