sirs,since gumagamit kayo ng racing cdi or cdi with ahigher limit..have you chnaged your valve spring aswell? i was told that i must to avoid valve float. whats thee best valve spring brand? and doest it specifications?like how much rpm it can handle or size? i was told r15 valve spring is agood choice.
Bro! Once you upgrade CDI to RCDI its a must to change your Valve spring to Racing valve spring to compensate the allowable RPM stock v spring can only handler up to 900k RPM, that's why you need to change it to racing valve spring for you to avoid valve float Racing CDI has no limit your RPM can go upto 1.2k rpm, if your using stock valve spring on RCDI its close so far Vixion valve are the highly recommended to use, but I use CMS much stiffer than vixion brand, and I am using it for over a year without any problem,
Take Note :
when I 'am use this CMS Valve Spring, R15 Valve spring is not yet available out in the market as you said it was fit on our t135 honestly speaking. I`m Not sure regarding this.
