Titanum valve tips

[swampbuggy]

What is the smallest stem size that one can employ hard steel tips ? Thanks to all, Mark H.

Titanium, sorry.

I believe my 6mm xceledyn's have them... I'll have to check.

Update... 6's don't but the 7's do.

I'll have to have these cut down to work on anything I screw together so lash caps will be in place.

7mm is about it, but it is still getting a little sketchy IMO
Lash caps are good, except for the weight! Lol
But if you go small, it's just the way it is.

[swampbuggy]

Going with smaller stem size was about keeping the weight down but I'd rather stay away from the last cap if I could so I don't know yet another hard decision

I have steel lash caps on 4.5 mm Ti valves. Engine is 2 valve OHC with rockers and screw lash. 15000 rpm reliably.

In what engine what cylinder head and what RPM

[Momus]

Small OHC Honda horizontal. Takegawa head. 15k.

Ahhhhh, yeah thought it might be a mcycle.
