Thanks Dayton,

That was what i thought.
Most guys that have problems usually cause them by themselves.
I know i have with other motors when i stuffed up and caused the motor to have problems.
Besides Novarossi have been building these things for how long now?
They are still the best by far.
How does the R5 Conrod hold out?
Did you replace it after Run In?
Some guys say you should and on the Axe Rossi site they say the same.
I have a friend with a FX21B5N and he reckons he has put nearly 60 litres of fuel through it and only changed the bearing recently but never worried about the Rod.
