Description Item #KIB0009

Kibblewhite intake valves are a great upgrade from your O.E.M. motorcycle valves due to their superior performance and outstanding reliability.

All KPMI Black Diamond stainless steel valves are impregnated by a special German process to a depth of 0.002", with a surface build up of 0.0002". This "Black Diamond" process improves wear properties, reduces friction, and provides resistance to corrosion and wear that is superior to chrome and nickel electrolysis plating. Each valve is designed using Finite Element Analysis software, and profiles are tested on Kibblewhite's computerized flow bench. Black Diamond Valves are light, strong, one-piece forgings with profiles that provide excellent flow characteristics and will outlast titanium valves.

Horrible

The neck of the valve severed about 60hrs in and gernaded the whole top end. DO NOT BUY

got these for a 07 crf450. had been using another brand of SS valve. These are very nice. easy install once you get the head off with the correct tools. From other reviews I have high hopes of putting some hours on these without issue

Won't last

Bought these along with suggested spring kit in April of 2013 only rode 27hrs and now its time to replace already. I don't ride hard and only ride in the woods so I am not bouncing off rev limit or anything. Just poor quality valve.

Kibble White Intake Valves

Replaced my last set of KW with new again. These along with seat regrind and new seals have returned my 2002 crf450 to awesome performance. After about 135hrs on the last set they needed it but I will keep doing this until the head reaches its limits in life. Love the KW intake and exhaust along with 13:1 compression.

BEST VALVES THERE ARE

These valves are AMAZING!!! 1. SUPER DURABLE: After one break-in ride, I haven't had to adjust my clearances once yet. 2. THE POWER!!!: The power increase from replacing my old stock valves with Kibblewhites was CRAZY. It felt like I was riding a brand new bike!!! My bike was so much more powerful that I actually cased a few jumps before I had gotten used to it. GO WITH KIBBLEWHITE!

Don't buy the expensive junk!

These valves are built to exact spec. They fit great and after i broke them in i haven't had to adjust. Don't use without the spring kit, they are heavier than stock so you need the sual springs or you could have a broken spring.

Be warned

A friend of mine and I both installed the over sized intake and exhaust valves with great power results, but the down side is that we had too aggressive of a cam. We both snapped off one of the intake valves. We are both running 9i cams but if you are running a Hot Cam you will be fine. Other than the breaking valve they were great.

Fanstastic valves

These are really nice valves, I could tell as sson as I took them out of the package. The coating and craftsmanship is exquisite. I installed these in my 06 kx250f along with the heavy duty spring kit and stage 2 cams. Great improvement!

Worth the Money

I ride a crf 250, I am currently on my 3rd set of valves and 2nd head. 2 of the 3 sets of valves were kibblewhite with KB springs. After breaking these in they don't move and are extremely tough. I ride my rev limiter a lot when I am racing, and these take the abuse without missing a lick. I cannot say enough good about these valves. Unless you are a pro you will get plenty of use out of these before your next valve job.

1 year 7 months ago
I've got a 2004 yz450f that I plan on doing cams and a 13.5:1 piston. While it's all torn down I wanna replace the valves. Can I run these with the stock seats or do I have to have New seats installed? Thanks.

Q: Stock valve springs?
Over 6 years ago
I have stock valve springs and want to run these kibblewhite valves on my 2008 crf250r. Would it be ok if I ran these with my stock springs? And are oem stock springs titanium or stainless steel? I am a beginner also

A: Your OEM springs are stainless. You will need to buy Kibblewhite springs, do not reuse your stock ones.

A: i would reccomend using the kibblewhite kit but you need spring stronger than stock because they are heavier than stock. typically any dual spring would work.

Q: Just the valves?
Over 6 years ago
If I were to only get new intake and exhaust valves and not the springs too, would I be able to run them with the stock springs on my 08crf250r? I dont have the money right now to get the springs too, and my springs are still fine. Thanks.

A: if you are running kibblewhite valves then you need to run the kibblewhite springs. otherwise engine damage could occur.

Over 6 years ago Location: south jersey
A: i wouldn't do it.... you could end up spending a lot more money in the long run if you use stock springs. they might last a little while but they aren't strong enough to handle the increased weight of these valves and could break.

Over 6 years ago Location: USA
A: I would suggest the standard valves, unless if you plan to port the head and rebuild the bottom end (or stroker kit). Keep in mind the oversized valves will require the head to be milled to accommodate the larger diameter valves.
