the local guru shoulnd have to do any thing as the cams have been machined wrong hes a enginer not a magician
u should be able to bolt them in and crack on if they are machined correctly
wat do u sugest chris ???

I am 100% with your opinion Mark ..that u should be able to bolt them in and crack on . But the thing that are not machined correctly it isnt the end of the world. You can always remachine them.

If you have plenty of time you can sent them here with the datasheet and i will correct them and make them ADJUSTABLE aswell.
And the most inportant... FOR FREE. (only transport cost you need to pay).
But i need some time as i am too busy at the moment.
What sam say about the wrong machine job caryed on them?

even with the data sheet in front of me these cams wont work without further machining.

The local guru couldnt do anything with them....:homer:.
I beleve it is an easy fix from the time you have the datasheet of them.
You could ask for abroad help anytime Mark..;)

Hey Rory

I know it sounds like a take the Sams side but i honestly dont.
It is 100% Sams fault to release them while it is an engineearing fault on them so they are not directly bolt on.

Ofcource the data sheet will do no much more than indicate that the cams are out of the degrees they should be and ofcourse you need to remachine them so they seat at the degrees they should be.

Same offer to Mark stands for you aswell if you want to continue bothering with them.;)

the thing is with the reprofiled cams is that they macine the base circle to increase the lift - as was the case with a set i recentley bought.

i sent them to my head dude and he is well within his capabilities with this sort of stuff and more.

he says that when they reprofile the cams in this manner ie maciningthe base circle it gives far far too much clearennce - dont quote me on the exact measurements but he says that

the current clearence is 4mm, it needs to be 4 thou - so its fucking miles out.

and then the problem with reshimming to this degree is that the buckets then have to be changed because if you try to put a bigger shim there - it will be more out of the bucket than in it and make it very probable that it will flick out and fuck everything sideways.

the way to sort this is to have some kind of valve nipple and do away with lots of bits in the head but then by the time you have spent money doing that you are talking a few hundred quid.

and my issue is that i was gunna spend around £500 including porting/polishing etc and i am not gunna have that kind of coin to spend just to get those reprofiled cams fitted

which is why i want some that the clearence is ok on but at the mo it dont seem like these speedvision 1's even work !

You can remachine the valve seat to reduce the gap. (you should do that job in every head rebuilt. I see it like normal action to take regardlless the cam will be used).
And also it is a good cheap trick to keep the shim on place in high rpm ;)

surely lowering the valve seat would increase the gap between shim and cam ??

yaris solid lifters fit in starlet heads so that sorts out the issue of large shims.

100% correct but this is the expensive solution...:p

Machining the valve seat means the valve will seat further in the combustion chamber and more stem will be out toward the cam side.
Then you need to cc the head and play with the spring pressure (undershim them) to be excellent.

machineing them ??? iv already had them machined to get the gears to fit
if i they need more machineing then id would of been better taking a chunk of metal and making them my self at least they might run then :p
thanks for the offer but i cant be fu*ked with the hassel and time taken trying to fix these so they will be getting sent back and ill be demanding a refund :mad:

the two seperate cams i got sent were both good with regards to clearance, they just were way out timing - wise.

sam messaged me that if they couldnt be fixed then a new exhaust cam would be sent out-again. however im kinda losing faith in the product. if sam can convince me and others he can fix the problem then i would accept a correct exhaust cam. think id rather have a refund.

unfortunately sam says he wont be offering any refunds. hopefully he could reconsider for his own reputation.

on a side note i found the exhaust cam to be wrong but im not 100% sure the intake was right although it seemed to be. has anyone got info on whether its just the exhaust one or both?

no refunds for a fault thats clearly his???

maybe not his but certainly his manfacture,

if he doesnt give refunds, he should be kicked of the site, theres to much dodgy shit on here already

I got as far as checking the exhaust cam, and it was out, i wasnt about to waste anymore time on the inlet cam.

Sam knows he is selling goods he has no grasp on ;)
Hence he always needs feedback on the problems. I genuinly beleive he doesnt know what he is dealing with here.

Shame really.
Even if it is the manufacturer at fault, Sam is still retailing these even with known problems.
