Aftermarket valves

[smw450r]

Hey guys port and polishing a head for my 05 model I'm about half way done I've already bought some Kibblewhite valve springs and I'm thinking about going ahead and buying some valves while I'm at it are the Kibblewhite valves worth getting?

[xcracer416]

yes they are just fine. i would recommend +1 exhaust though

How much roughly does it cost to send my head head off for +1 exhaust and who would be some good companies to look into to?

DC Cycle. hands down the best 450r head builder. proven reliablility, and he does exactly what you tell him to do, not what he says he thinks you want him to do.

i have been running his engine package all year and dont have the first negative thing to say. his time frame, pricing and service are far better than eny others out there.

256-356-8911 ask for david and tell him everette sent ya.

as far as the pricing, its best if you call him. he can put different seats and guides in along with different brand valves. David keeps most brands of each in stock, its up to you on which you go with.

i went kibblewhite with stock guides and copper berrilyum seats, after 10hrs on my new head i didnt have to adjust them. when i refreshed my topend at 20hrs the was still spot on.

Some use kibblwhwite and like them but ive seen way to many snap for me to ever use them, ID get +1 ferrea ss valves and KW dual springs thats a pretty common setup on big HP motors..

Ok guys thanks for all the info looks like I'll be calling around to a few places

ferrera valves are by far the best, i snapped 2 kibblewhites before, wouldnt buy them again
