It stopped sucking the oilafter we changed the seals. Doesnt smoke as much with the pwk as it did with the tmx. My dads buying some master links today.
If it smokes less with a different carby then it would pay to check your jetting as less smoke could mean a leaner AFR.
Did you plug chop after the carby swap?
What were the results of the leak test after you fitted the new seals?

So you are going to put some new links into an old chain!
I hope you realise that every time the new links go around the older sprockets the chain will tighten owing to the new links wanting to ramp up the leading edges.
Now the danger of chain breakage goes way up.
When a chain brakes, it normally shoots one end through the crankcase.
This can be quite expensive. If the chain jumps off the sprocket it can lock up the rear wheel.
If you are going really fast, even if you are not going fast, this can be very exciting, also very painful.
If you are willing to live with the breakage and lockup risk, by running mismatching chains, for your sake give KOR a call and order a case saver.
