with gasket sir. are you a cms user sir?

 

[rowan]

yup gamit ko 2 mos na . pocket ka lng for safe reason. ok yan basta kasama mo lng v spring. dahil kng wala, valves mo masira like my friend mahilig bumirit la naman valve spring. mahal pa naman exhuast valve sa yamaha 3s.

 

[vav_mugen524]

Dpat tlaga may v.Pocket kasi long durati0n xa. 5.8mm lift at 280 deg. durati0n. 2-3mm deep dapat kasi nag eexpand and aluminum or bakal kung umiinit.

@ turbulence = ayan may naka add pa so mag valve pocket ka talaga tanx kay vav_mugen524

so far sa akin okie pa rin 2mm no base gasket .

 

[vav_mugen524]

Bro rowan bakit exaust valve ang natatamaan sa CMS CAMSHAFT? Karamihan na cams ay sa intake valve?
300 degrees daw ang durati0n ng CMS cams kaya neEd talaga ng valve pocket.

 

[rowan]

its my friend,s bike . dunno why exhaust valve , basta AFAIK hindi xa naka valve spring. i know nka pocket xa but same results
ex valave nya tinamaan parin. dunno why.

mine 2mm pocket lng no problem naman

my bike also using CMS cams and CMS v. spring w/o V. pocket - . so far so GOOD
Q : Do a Valve pocket can Affect compression / performace ?
Thanks

 

[vav_mugen524]

Yes will effect compression if ur valve pocket so wide and deep.

 

[RTG]

Thank bro .
in my current setting there are possibilities to hit the Piston head ?

And where is the Trusted Machine shop / mechanics to do a perfect v. pocket ?
