They are cheaper compared to other brands of v.s. No negative feedback so far to their bore kits. They are indeed durable.
Me too, just curious with their springs. One shop here told me jvt springs are better than mtrt valve springs. They dont worn out easily compared to mtrt springs.

Really? Thanks for the information sir.
Actually I've inquired to them thru YM.. It's very cheap! compared to other v.spring brands.. That's why I started this thread because I want to buy one set of it..
I also inquired to MTRT Philippines via whatsapp, They told me that MTRT passed the 12000 RPM test and guarantees that there will be no valve float but it is not applicable to cams with 6.4mm lift.. I'm not quite sure if the mentioned lift is the max lift allowable for MTRT v.spring and beyond it, it is already not recommended.. this is just my understanding in their reply..

I wonder whats the limit for jvt valve springs. Cms are good BUT they are so stiff that you need to check your valve adjusters for they will worn out easily.
Thas why im not going to use cms.
Vixion are good to but the limit is 12k rpm.

I wonder if jvt and vixion valve spring have the same stiffness. Vixion v.s is good if youre using low lift cams or stage 1cams. I just doubt if it can handle stage 2 cams.

Just want to be clear. Youre using jvt valve spring? How about the cams?

Btw CMS spring is good enough if you are hesitant to used cms it is because of adjuster problem it is normal but it depends of your mechanic settings, good item +good mechanic = good performance

Thats what im afraid of. I dont want to damage my valve adjuster bec. Of a very stiff valve spring. Im planning to use cms stage 2 cams. The only problem for me now is what valve spring will i use that will not damage my v.adjuster but has high rpm capacity?

for you to know sir valve adjuster is a consumable parts on our bike so that you need to check on this in a right time..always remember if you need a performance engine you need also spend money and time to maintain...just my two cents
