32mm exhaust valve ordering info

interesting stuff Spanner

I used iron guides all round on the 700, the intake side with kibblewhite valves are not worn at all but on the exhaust side (Taffwad cooking valves) both guides are stuffed and the valve stems are worn also. 250hrs

exhausts have a harder time but maybe also something to do with the DLC coating on the KW being a better match with the iron than the plain steel exhausts

the LW head has bronze guides and DLC coated valves

these are the ramblings of someone who needs spoon feeding by the sound of it. where do you start...

well you can't sink a 32mm valve on a a seat by 0.5mm and use the same stem length as said at the beginning. you really, really don't know what you are on about!

secondly, the flow is far poorer if you don't move plenty of metal.

not sure what your point is about the dyno figures? mine are what they are and 'steve's are what his are. they're on paper. I think mine had a back credit for the knobblies to get the figure just to stand corrected.

compression is lost negating all the gains.

and as said:
ANYONE CAN SEE THE REFLECTION OF THE POORLY FOCUSED PHOTO FROM SPANNER BUT I'M AFRAID THAT IS A DOMED VALVE STEM. my cam chain claims are correct and you've had plenty of people here tell you how good the IWIS is and how they last longer yet you choose not to listen.

but at the end of the day all you can is drag old **** up, not much of an argument.

you've been found out to be wrong on the last what 5 subjects in under a month.

fact is I raced, I won. that is proof.

you never raced, you bought a Lineaweaver head with the valves and everything so what genius flowed from you?

Taffy

nope its the pic mate spanner is perfectly capable of inspecting parts for wear, just as Steve is perfectly capable of knowing there is nothing wrong with his 650.

the point with the dyno figures is that anyone who thinks their 400 in any state of tune compares in any way to steves 650 based on the graph in question has a serious intelligence deficiency. Evidently race wins don't change ones IQ



3 points you still cant grasp:

1) the valve in question is already too short so the sinking helps with the valve length (don't you think im smart enough to know what happens at one end of a valve when you move the other LOL)

2) the total increase in head volume in this head required to increase the flow over original after sinking 0.5mm is less than 1cc including the volume gained by lowering the valve itself

3) total change in compression for all practical purposes from this is negligible and if you set the squish properly the compression is raised and the loss is negated.



Taffwad if you accuse me of lies and mechanical incompetence in any thread i will bring up what ever is needed to put your comments in perspective. If you play nice I won't mention a single thing... entirely up to you.

in this thread for example all you had to do was post you had 32mm valves available.. simple ..

since you ask ... your claim that the IWIS cam chain is 30% lighter and 30% stronger than standard is complete BS this is verified by others. the IWIS is 6% heavier. yes it is a good chain .. no need to use false advertising to sell it.

your claims about your valve spring specifications reducing seated force over OEM conicals by 40% were proven to be completely wrong by comparing your own figures with the OEM conical seated force. I tried to tell you privately in 2009 that the figures didn't add up and got told I was being far too anal.

the oem seated force is a finite value verified by many competent people. The KTM DVSK is a fraction of the price of yours and has the same coil count and wire diameter. The Kibblewhite set is the best.

attacking my integrity won't help: nobody has to believe a single word I write, the OEM specs VS your claims are proof enough

again .. you play nice from here on and I won't bring up a thing.

where?

where what?

if you mean verification regarding the weight by someone else its in the thread I linked mate.

I asked politely at the start of that thread for clarification of the weight reduction claim

if you would like to address that with a response then the best place to do so is in that thread

Taffy "ANYONE CAN SEE THE REFLECTION OF THE POORLY FOCUSED PHOTO FROM SPANNER BUT I'M AFRAID THAT IS A DOMED VALVE STEM"

Wrong, anyone can see this set of valves are new, have never been used, is just an illusion.

I think the tappet set up on the husaberg is probably fairly kind to valve stem,
regarding wear.

Tribology is a fascinating thing

the LW valves have a very very hard stem end surface.. they are pitted like you would expect from hertzian load failure where the failure is below the surface between the hardened surface and the substrate,

the OP indicates the stem on his LW valve is also not so good.

I resurfaced mine, will see how it goes

the Kibblewhites are also stellite tipped but in comparison are very soft and stem wear is not a problem at all.

so in short too hard is sometimes no good.
