As mentioned in another thread I'm putting a SR190 together using a box of bits that used to be a Super Vijay. The crank looked to be ok ish at first but un closer examination there is a LOT of side play on the big end (there are no big end shims)and what appears to be a pair of gudgeon pin shims in the box of bits.

On top of this the rod is slightly bent :cry:

The question is, is it worth having it repaired or would it be cheaper to get a new one?

Cheers

yep, CSE fitted an RD400 rod to an AF crank for me, top job of course, tigged the pin as the "race" crank had badly twisted after a few hundred gentle miles :evil: , and you know it's now strong & true.
the [107mm] rod from my crank is probably still up there, you can have it if it can be found.

MEC EUR black race crank would be ok for that. about 80 quid. glasgow lambretta did me one , and with a couple of seals and some other small bits to make it up to 100 quid, the postage was free as well. bargain.

Thanks Goldeneye, I'll file that away for future reference, my next project will be a 225 possibly a Rapido so a more robust crank will be called for and a MEC would probably fit the bill.

I've one in my muggy 225 since '05 and it's been well thrashed. I'm more than happy.
