[risky bizzness]

have had my crf250r for just a little more than a year...have had to replace the valves and springs with the kibble white kit just after 8 hours..have had to readjust the valves 3 times now...just would like to know if any body else has had this problem...this is my first year racing and i am looking forward to the season...good luck to all and be safe...

Did you have your seats touched up before installing new valves?

You should have gotten the Kibblewhite Valves...I hear they are much stronger

By the way, did you put those gibble white ones in yourself?

Oh, and welcome to TT

Call RHC!

yes the head was done preferentially by heavy buty racing in v.a the seat were recut sping pressure set all the good stuff...my cousin has the 07 crf250r with 3 hours on it and the valvas are tight 4and 9 should be 5 and 11.

i love my honda's. my son rides a 04 crf100...i've done some suspention work to that...if you don't have wings you don't have a prayer!!!

[weatherman64]

your valves didnt go after 8 hours. Youre probly made a new account to talk shit about hondas.

[risky bizzness]

no your very wrong i'm asking if any body else is having the same problem...just like i just said i love my honda..

[FreeStyleMx]

Nope, not had that problem.

[risky bizzness]

how often due you check them..i check mine about every 2 or 3 rides

[Honda_250f_rider]

Kibblewhite valves are inferior, have read may things about them, so they could get tight after a little amount of time.

But still valves SHOULD NOT get tight after 8 hours, try 80-100 hours before the first adjustment. I got 100 hours before the first adjustment on my 06 and now 10-15 hours later, when I did the piston, they have not moved at all.

I think every 2 or three rides is excessive, I would be checking them every 30-40 hours

Just keep up with regular maintenance and everything will be fine.

thank you for the info...iam riding and racing on a very tight budget..ichange the oil every 3 hours and so on...

[FreeStyleMx]

I check my valves like every 20 hours, Have to do it a bit more often because I do ride the bike hard, and it has a racing cam in it.

But yeah, 8 hours is absurd for them to get tight.

If your on a tight budget, dont change your oil every 3 hours... Some people change it every ride, but most, including myself change it about every 2 rides.

Your oil doesn't go bad in 3 hours, even if you race it.

Both of my new bikes were out of spec after break in.You should always check a new bike after break in and set to your liking and to also know where you start at.4 is still in spec,9 is still ok but not in spec acording to the manual.I set mine at, 8 ex and 5-6 in, per my mechanic.He says he sets some of his race bikes at 5&5 a little hard to start but making max power.

I rode my 05 crf 250r five times in the desert and the valves mushroomed. Got kibble white valves and changed gearing to 14/47. the valves havn't moved since september. Break it in nicely after you install new valves.
