I took the head off my bike, out thesese valves in, out the back back together and with some tweaking on the carb it charted right up
we use this product in our shop and for our customers never had any problems
Good valve for high power
Installed in my 05 crf450r and work very well. No power loss noticed. This is a high quality kit and beats others I have used and seen. Swirl polished valves and quality machined parts. I am a Tool Maker so I look for quality machining. Would highly recommend. My bike pulls on my buddies 08 rmz450 so I am pleased.
Its hard to compare before and after power, but there was definitely a lot of power coming from my CRF250R after I installed these!
Great kit, installed into a crf250x with no issues hopefully will last for a long time. Very complete kit packaged well and each item was individually bagged.
These valves were perfect in my 2010 kx250f, they seated good and the springs and every other aspect of the valve kit went in my motor great! definitely recommend these valves and motosport for any engine parts!
Once you install these. Forget them cause they will continue to perform.
Fantastic product! Quality looked amazing out of the box and brought them along with my head to local shop to have seats cut and kit installed. Hour later I was home bolting everything back into specs and my bike roared back into life. Incredibly pleased with the product and my bike feels incredible with this intake kit installed. Cant wait to get back where I belong!
I installed these in my 2011 KX250F serious power loss and awful starting when hot I changed to these valves because the oe valves were not lasting long at all. After using these I switched back to oe valves. They are lappable into the head and easy to install but if your gonna race the bike do not use them!!
I installed these in my 2003 CRF 450 when the stockers began tto stretch. They have been worry free ever since. I would buy them again
Easy to swap from OEM and work really well
I installed these on my 07 CRF250R after fighting with the factory valves. I installed these along with stainless exhaust valves and have yet to adjust them after several hard rides, and a weekend at the dunes.
These valves are great. When first installed they have around a 5 hr break in period. After the valves settle and seat they are by far the best valves i have ever installed. I installed them in my 05 CRF 450 that has many motor mods because i kept stretching titanium valves. There is no power difference what so ever and with 20 hours on the new valves they have not stretched even .001 inch. GREAT PRODUCT
supurb machining,both springs & valves weighed excactly the same to the .ooo. If you dont or cant cut new ceats on your head this will cost you about another $75-100 at your dealer. Kit does not come with new cotters (retaining pins) but the old ones were just fine.
Let me take the time to maybe save you more head aches. if you are also switching out to a new piston, basically the top end do yourself a favor and also do the bottom end as well. in a matter of time that new fresh top end will blow out that bottom rod bearing. These motors turn some high RPMs. I reused the cam & cam bearings, retainer clips, intake caps& timing chain. Have over 15hrs of some hard riding, no wear on the valvaes yet. RUNS GREAT!!!!
I installed these on my 2007 Honda CRF 250 R. I have about ten rides and races on them and they seem to be holding up well without needing shimmed liked OEM valves. I should have installed these a year ago.
My 2005 Honda 450X was in need of new valves and my friend told me about the Kibblewhite kit. Motosport got them to my door in just a few days. I put them in and my bike runs and starts great. I am very happy with my decision to use Motosport.com for ALL of my motorcycle needs. Thanks.
don't bother with anything else, this kit is the best one you can get. they are a little on the expensive side, but these valves will last. i can't say enough good about this intake kit.
