psychic mx ss valves?

I Found Some Valves On Ebay For $46 For Intake Valves And Springs, Has Anybody Ran Theese? They SeemTo Good To Be True?

[Shawn_Mc]

Oh sure, just because they only cost a quarter of what the OEM stuff costs, they're probably fine...that'd be something I'd shy away from.

I Dont Want Oem Ti Is Junk In My Opinion But Ape Is Only $110 And I Was Wonder If AnybOdy Has Ran them

OEM is not junk. The seat material is the problem, get your head rebuilt with good seats and guides and you can use OE valves And they'll never move.

I don't know that id trust 49$ valves.

if you do ss valve, have the seat recut and it will last a long time (with proper springs to match the valves) oem and titanium vavles are a great.... if you can afford copper vavle seats.

I always sent my crf heads for work overs to these guys, I I did the 599$ package on my 07 crf250 (ss exhaust valves & matching springs, ti intake valves & springs copper intake seats, bronze exhaust valve guides and a head port.

Did you notice any more mechanical noise ?

None worth mentioning. And i got 2 hard seasons on that head befor i sold it, valves moved during break in and that was it

[Qqqqqqqqqqqq]

Ok .. My valves have not moved at all ( 150 hours )

but it is loud mechanically which is annoying

It makes no sense for the average rider to go back to the stock titanium. Unless you race and race only and you are looking for that extra 300 rpm and .5hp. You will spend gobs of money on a head changing seats and all that. As for the psychic valves I have never herd of them but i do know that if they are made with the wrong material they will beat up quick. If they are not tempered properly the valve stem will warp with the heat and cause the valve dance on the seat beating the seat to death and killing the valve job. As for the bigborethumpers.com/APE valves i have been running a set in my 03CRF 450 for 5 years now and not had an issue yet with them. Not even a re shim.
