    malossi 172 kit, crank question

    right, if any of you mechanically minded people were to put a malossi 172 onto a mk1 t5 that has done 22,000 miles with the same crank , would you put a new one in if the old was was cushty or would you get a new one?

    I'm only pondering this because some people have said get a new one and some people have said the old one will be up to the job, would all you top boys tell em what you'd personally do!

    many thanks

    The inlet timing should be ok as is if that's what you mean, but at the very least whilst the crank's out I'd get it to a scooter shop to have it checked over for wear on the big end bearing and any twisting or misalignment (T5's are more prone to this due to a) the higher rev capacity and b) the shitely designed flywheel bearings

    Providing it is in good condition the original is the best

    whatever you do if you replace, and you are sticking to autolube MAKE SURE you check the autolube cog seats on the woodruff key as almost all of them are machined wrong, which will fuck up your nice new crank and the top end.

    If it is shagged I think you can get new genuine ones from PM running, worth a look?_
