Tips: Change Valve Spring to increase rpm and speed

i use cms valse bro. is it ok? and what do you mean "non magnetic" valves?

 

cms is tried and tested, it is ok bro, in non magnetic valves, the valves are not attracted by magnet, like stainless its tough, so it wont easyly damage your valve tip , some mechanic told me that

here is my video, my new parts, look what happen to my valves hehe because of aftermarket cam and valve float

 

Up.. Keep coming idols...I'm planning to change valve spring

 

malakas ba lagitik ng CMS valve spring compare sa vixion? any cms valve spring user?

 

depnde sa pag set yan sir..kahit hispeed pwedeng mahina lng lagatik na parang vixion spring

 

you won't go wrong if you'll use vixion valve spring....northloop tested

 

vixion valve spring using here, very much satisfied on the performance and durability. even on high rpm and miss gear still mu MC is smooth and running without problem.

 

from the name itself, its assured that it is genuine from yamaha vixion MC. quality MC part.

 

is it possible to use washer on stock valve spring and valve to make it stiffer ?

 

adding washers will put the stock springs in "more" tension and may make your stock valve springs prone to early coil bind ( you have shorten the compression travel of your spring.) rather than in the "normal" compression state. an upgrade is better than a backyard do it yourself and end up catastrophic engine damage. ouch!!

 

So it is possilbe to use the vixion valve spring and reach 11k rpm with out damaging the valve tips ? ( i do plan to install the mxking valve adjesting screw too )

 

which want in vixion??
