I am currently negotiating with a fellow for a set of 450CC blue tops, the car has 189,000 kms on it, so 110,000 ish miles. Do they have too many miles on them to be usefull, they came out of a running car for larger injectors. Anyone know what to look for?

 

Naw, jsut get them balanced and flow tested.

..they should be fine.. as long as they were maintained.
