whats special with kitti valve retainer kit?
im interested...

 

[docgabby]

hispeed valve springs are stiff! stiffer than yy pang, lhk or the rest. hi speed uses there own retainers to match the valve spring they recommend.the diffeence from the stock retainers is that the recess for the valve lock are much deeper compared to the stock retainers.

what is the strong point of using TK spring compare to other aftermarket brand?

P/s for my knowledge only and don't have avy intention to condemm any brand :mrgreen:

would it improve top end speed and performance if i install ONLY aftermarket valve springs on superstock t135? how much is tk? also what is valve float? sorry for newbie question..

i use this for 14k rpm http://www.yamahat135.com/forum/viewtop ... 7&start=40

@kid
nice springs kid

you need to change to aftermarket cdi so that you can benefit from aftermarket valvespring.
stock valvespring can only reach 10,000rpm
aftermarket valvespring can reach more than that...

bro this is what valve float is.
it bounces like a basketball but "uncontrollably"

thanks for the info sir, so pairing an aftermarket valve spring with a racing cdi prevents my engine to blow due to overrevving?

@2b1

yahh something like that, remember that theres a possibility
that during valve float theres a possibility that the valves and piston will collide due to unsynchronized movement of valves with piston...

so far i have tried around 3seconds or less of valve float then shifted to next higher gear... so far no collisions occur...
so valve float with "krrrrttt" sound is an indication that youve reach
the highest rpm that valvespring can attain...

bro valve piston collision will not happen until you squish it... remember theres an extra 1mm gap.....possible collision on this is intake vs exhaust valves..

thanks very much sir traxxas and chiglai

im enlightened now, im gonna change my valve spring when i change to racing cdi to prevent valve float since our stock valve spring can only handle 10,000rpm and by changing my cdi im gonna be revving higher than that due to no limiter feature of new cdi, thanks again.

now im wondering how much and what brand is reliable for everyday use valve springs paired with Rcdi, more wishlist for santa

Revving more than 10K rpm will not get you any thing unless you have a cam to match the rpm.

 

[traxxas-modifier]

az it will give you something bro
you will increase the maximum speed of each gear
