Titanium Valves

What are the benefits and downsides of titanium.

I know I have to run lash caps but what else?

One of the guys put TI valves in his 8.20 bike last year. It ran slower and he went back to stainless.

Plus they cost a fortune.

Is there any scientific explanation why?

Plus they cost a fortune.

A professional race mechanic friend of mine is gonna sort some out for me.

He has his own shop and it sounds like they will cost very very little

heat disipation and wear are the main reasons.
they disipate heat better, wear better and are lighter

Sorry im lost.

Is stainles or titanium better and lighter

[rosco15]

No scientific explanation. Just real world testing. The bike ran slower so he took them out. I was surprised to hear it myself. Maybe it has something to do with the shape/design of the TI valve.

[Silvermachine81]

Wow, Yeah it must be the design of them.

You think given the price that they would rock!!!

street bike? SS

street bike? SS

Why? Clearance issues or something

I'm gonna be getting these cheaper than a set of stainless

Keep in mind that if you go to titanium valves you need to change the valve seats to copper berillium. Titanium valves are not compatiable with stock seat materails. Very expensive change over. Mike J

I have stainless steel in my 1000S.
Got them from Orient Express, cheaper than the stock vavles.

Stock cams, 3 angle valve job. Stock carbs jetted, 4>1 V&H pipe
Nothing fancy, just breathes.......

ti is good for a high reving motor (lighter less valve float) they also flow better because the tulip (where the head and stem meet) is thinner. they are a must if you go 33mm stainless is way to heavy. downsides: they are close to $100 a pop. you have to run lash caps, star retainers with lash caps built into keepers, or gsxr shim type retainers and shims (i like these best because the caps spit and the star deal breaks the tip off the valve) if it was me and i wasnt running pro stock. definatly stainless

I understand wear is an issue...
