Clutch springs - what do i have here?
I got this set of springs from VT 6 years ago and never installed them on my clutch. I believe i still have the stock ones, and a 1000 RPM KRS spring that i did install.
These are kind of a brownish black.. Do springs are coded with colors? I saw there are yellow and blue so do you know which ones do i have here? what RPM are these? And what difference will these make on my Dio?
Thank you.

Greetings;
I suggest you mic the wire thickness and someone here can compare with you.

Re: Clutch springs - what do i have here?
I don't know if there is some sorta industry standard or not. But the spring colors I normally see are...
Blue = 1k
Yellow = 1.5k
Red = 2k
I have no idea about black.

Yeah I don't think there is any standard
That sucks.

Re: Clutch springs - what do i have here?
Doesn't the color code specify how many RPMs the new spring takes up above the stock spring's take-up speed? A yellow 3K would make more sense then if your stock spring hooks up around 2K. Idle on these 50cc Hondas is about 1800, so ~2K could be a reasonable assumption for a stock spring. Yellow would just hold back another 1K before engaging at 3K RPM.

Re: Clutch springs - what do i have here?
When talking about clutch grab springs, 1k's 2k's or whatever, it is always 1000 rpm or 2000rpm HIGHER than stock.az_slynch wrote:Doesn't the color code specify how many RPMs the new spring takes up above the stock spring's take-up speed?

Re: Clutch springs - what do i have here?
There is NO INDUSTRY STANDARD COLOR CODE for clutch springs and center springs. Colors and designation varies by mabnufacturer, makes it hella more FUN!

No color standard, but it's a safe bet that the wire wound into those coils will be thicker on the stronger springs. Material quality will affect durability.
The Taiwan set I purchased measured 1.0, 1.2, 1.4, etc. in blue, yellow, and red.
Get a Harbor Freight digital caliper, it comes I handy for $15.

Re: Clutch springs - what do i have here?
ok.
I measured them today with the digital caliper and got roughly 1.7 mm of wire thickness. There was some variation at different points ranging from 1.67 to 1.73 because i guess the caliper is cheap and the springs are not perfectly round but got 1.7 at many places.
Can you guys check your springs please and give me some idea?
Thank you.

Re: Clutch springs - what do i have here?
I think i got my answer here: http://cgi.ebay.com/ebaymotors/POLINI-P ... arQ5fParts
I had the springs stored in a small plastic Polini box so i guess thats what i have here. 1000 rpm springs.
What should i do then? get 2k or try these first?
