you have finally said something that makes sense.

yes!

but I have to be safe, I sell parts. he doesn't.

I had to check that the kit was good in a 400, and with the 53 cam. he never did.

and THAT, is what REALLY matters!

who gices a shit how light they are as long as they do the bloody job!

I would like to see the Discovery channel do a reality show. Call it the Battle of UHE. Set up live cams in Taff's shed and in Bushie's with monitors so they can see what each other is up to.

Bushie: "Well, I measured the osculating circumference of the radially entwined sledge valve with my home made laser increment adjuster and it's 000.00000001 out."

Taffy:"There you phuqin go again. Your not listening to what I said. The adjustment of the laser osculates in reference to the doc. The doc that I wrote. Now phuq off your ruining the show."

Etc..etc...etc...etc...etc...

It would probably out rate Vikings.

Everything seems to indicate that they do. We can know for sure if the seating force is known - Bushmechanic has done measurements.

Valve spring basics: Valve Spring Basics

If spring tension is too light, valve float and eventual engine damage can occur. If the spring is too stiff, friction-related horsepower loss and accelerated valve train wear will result. According to cam experts, one of the most common causes of premature camshaft failure is the use of improper valve springs. This can include too high or too low spring pressure, or the springs can just be plain worn out.
And - the stock 450 spring rate and length can be compared to the ATV springs for a good baseline.

I got the valve seals and if I remove the old ones the kibblewhites seem to install without any clearance problems seems like a perfect fit I do'nt think that it will be necessary to do any machining to the head/rocker cover but I am not that skilled to be sure...
The black washer suplied with the kw kit where does that belong??? it can only be fitted first under the big spring retainer or on top just below the titanium top retainer to me it looks like un necessary to fit it but again I am better at ridign than fiddling with bikes....
And is there a method to install the duals springs to be sure to have no coil binding???
I can make some pics tomorrow
Thanks from Hoosaberg, tourist and Blamir

Here I have 3 attachments 1 is the big retainer installed in the head the way it should (at least I guess).
In another picture the black washer sits on top of this retainer you can see it does not fit inside it it is the same outer diameter...
The other picture I put the black washer on the titainum part that goes on top here the washer seems to big to fit.....
