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.

bro you can use any brand of valve spring you prefer. just dont use sun racing valve spring. its spring is too soft and its more likely too have a valve float effect and will destroy your beloved engine..

Yes and no. Yes, i use sun valve spring before. I thought that it was just the limiter. But, that time i was using rcdi. The sound was kirrrrrrt during high revving. Different from the sound of a limiter of stock cdi, rapapapapapap. Ive read it before here in t135 page, that sun valve spring is not the brand of vs you want to install in your engine. So i changed mine to mtrt vs.
