Big Bore 440 Kit
#1
I was looking at this kit for my 05 z400. My question is how bad does this affect the reliability of the quad and how often will I have to rebuild? Is it worth the power increase? Thanks for any replies.

if its done right it wont hurt the reliabilty of the motor at all. I think it was worth every dollar I spent
its been 2 years and the only thing I had to do was carb work and valve adjustments
