    Oh well done on getting an engine really quick, sounds like you had this idea it was toast before you asked. Anyway in your position I would just check that the oil pump on your original engine is in fact the problem, you might just have to swap out the oil pump rather than trash the whole engine and then you will not need to change the V5 and docs. It sometimes makes sense to do a bit more work and get it right rather than rush at it and regret it later. Just sayin..!

    A top end swap and oil pump change should be about the same as taking the whole thing out and replacing it.

    By the way just check on your original engine that the oil-ways from the pump to the head aren't blocked by old oil and crud, it might be an easy fix and not the pump at all. Some folks (especially the younger ones) don't change the oil as often as they should and 125s are likely to be hammered by their owners.

    Yeah that would be my best guess as to the problem, it sounds like a lack of oil to the head which has caused your problem, you might be lucky and save the head and valve gear but if it's really badly scored then you might be looking at a replacement head and valve gear. Your only option now is to take the motor apart and check the oil pump and gears, sorry mate but it does sound like your in for a major overhaul of the motor. Where are you in the world? we might have someone near who can help..!

    What we need to know really is 1 Is there still oil in it? 2 What was the reason for you removing the cases before it locked up? 3 The reason Cynic asked the question was there has to be a reason for doing 4 oil changes and it might help if you told us why, You see it's really difficult to say what the problem NOW is if you don't tell us what you needed to do to it that meant you had to change the oil 4 times..!

    PS the engine will only lock up for a few good reasons, No oil (lubrication) No water (cooling) broken component. Lots of other reasons lead up to a failure but none of them start without the first 3.

    Look up most any write up on these things and you will get "Great bike, lot's of fun, but anything over 60 is a vibe fest" even to the point of one writer saying he lost vision when it got so bad, my best guess, this is how they come out of the factory. Go figure, but without doubt most riders love them.

    I can tell you it was MOT'd 26th April this year so it's still out and about and it has almost 20 thousand miles on the clock. Sorry can't be of more help. But I was wondering if you happen to know a really friendly MOT tester and you gave him the number of the test certificate he "MIGHT" be able to give you an idea of whereabouts it was tested and the tester might know where the present owner lives. Bit complicated and requires a lot of luck but worth a try if your desperate..!

    MOT test number is 2084 3915 0635

    Sorry but that's the way it is. Lot's of write-ups about this bike and ALL of them mention the vibby ride especially at anything above 60mph. Best advice buy a set of "grip puppies" for the bars, they make the bar a bit wide but do damp down the vibs on most bikes, a better and cheaper seat option is a good thick fleece to rest your bum on and the added bonus of a lot less numb bum on distance riding. Others will be along soon to offer better and cheaper options so just watch this space. :D

    Hi David, welcome to the YOC. As to the best way of finding out what it's worth with or without the chrome done, find out what a good thoroughly restored one is worth, cost out what it will be to re-chrome yours and there's your answer.
