Good job on getting it welded
when i cased my cr when i was alot younger i put hole in my water pump cover too. i used amorite stuff to patch it up and it held it good lol it did the job
also my water pump seal had gone the coolant had got oil n petrol in it but sorted that easy fix, loved that bike shamed it got stolen :/
question mate how hard are fork seals to replace my lads QR50 needs them replacing oil coming up out the forks just dont wanna fork out silly money to get it done by a shop if its a relitivly easy fix?
