Kibblewhite Valves

[mad715]

Anyone use or like to use kibblewhite valves and springs, if you can help with pros and cons and what is a good price for both. I have a trx 05 450r. Thank you for your help!

i have KW springs on all three of my heads, KW valves in 2 of them and ferra in the other.

my first head was done in 05 and has never needed reshimed
the second was done in 07 and the same never came out of spec.
the one with ferras is new

i havent had one single problem with KW stuff and would use them again in a heartbeat.

i do have an extra set of 04/05 kw springs, they are used but all are in spec i would sell for $110 shipped.

You have to keep an eye on the springs to make sure there in clearance. I had a couple of mine break on me.
