Are all the oil pump the same between different models? they look the same on the parts manual pages but the part numbers are different. i have seen a few nice pumps on the japan web page, but they are all for the 18 21 and so on.
i use the bike as a road bike so i am sticking to the oil pump. my oil pump was not functioning so i will try to fix it or get a new one.
is there a way to see if the oil pump is broken or is there a block somewhere? it works a bit on and off so the workshop claimed they made some changes and made it into premix with the oil pump still attached to the bike and there is this clater sound after they did this.
Any ideas?
