I have Yamaha YB100 two stroke model 2004. although the bike is in god condition. but one day when I was offroad at the speed of 100 suddenly my bike engine siezed in the middle of the road. when the engine got cooled it started again. I took my bike to technitian who said that your oil pump stoped working and due to over heat in cylinder head your engine seized. I changed the cylinder head.Now after changing it still my bike gets hot at the speed of 60.

I have noticed that cylinder head is now again giving voice like some thing got loosed in cylinder chamber. I again took it to the technician who said that add a bit oil in the gas tank (Petrol tank). but problem is still there. afterwards technician said now you have to change the cylinder and cylinder head at the same than your bike will be alright.

Please guide me what should I do. I love my bike.people say sell it but i want to keep it in its genuine condition.,

first off I would get the oil pump issues sorted (which may be just a case of bleeding and/or adjusting the minum pump stroke or at worst a new pump). If you dont wish to fix the pump add oil to the fuel tank at the ratio of 20:1 .


With an engine seize the piston cylinder stand a good chance of being damaged which may be fixed by boring the cylinder to a larger size fitting a larger piston ring set to suit the larger bore, this damage is most likley you engine noise.
