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
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.
Best valves you can buy! Fit is great and quality that is second to none.
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.
Needed new valves and springs for for my engine with putting a 440 big bore kit on kfx 400 have it in the shop right now getting all the engine work done so it is ready for the races hope she runs good with these valves that are said to be better than the titanium ones thank you motorsport team
this is a great product i recomind it to all
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!
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.
BEST intake valve ever bought i bought mxfaction valves and they went out in 1 week these are the best i highly reccommend this product
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.
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!
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.
Its Simple...These Are The Best Valves You Can Buy. Replacing My Stock Valves With These Valves Increased My Overall Performance And Prolonged My Bikes Durability. I Would Highly Recommend To All Riders.
kibblewhite valves last forever i love them they never get tight ive never had a problem dropping a valve and blowing the motor up like i did with stock valves.
haven't had any problems with them and ive noticed that i can go longer without adjusting them
