'83 GSX750 ES Valve Springs

[BananaSplit]

Hi All,

I have been searching for a new set of valve springs for a rebuild over the last 6 months, but only seem to be findings single or pairs of springs from different sellers on Eblag. I was wondering if anyone here could help me out in locating some NOS valve springs, maybe in sets of 4 if possible (so far I have tracked down 10 from 4 different seller, as you can imagine the shipping price alone is close to 200% of the actual price of the springs), or if anyone had tried an alternative set of springs that seem to work just as well or better than OEM. Any help would be greatly appreciated.

OEM part no: 12921-11410

 

Thanks in Advance!

thank you! I will send them a message and confirm if this fits.

I am just a little worried that the seat pressure would be too much with the dual springs on the stock system. If anyone has experience using these please let me know. And thanks again.

Dual springs are standard configuration from memory of last time lifting the lid on a GSX motor, I may be wrong but there's plenty of knowledge on this forum to confirm.

they did move to dual springs, but this was from the '85 model and after. the seller confirmed it would fit, but looking at the valve seat, I don't see where there would be room for a second spring as there is only one shelf for the spring to sit in. I have asked them if I would need to buy new seats as well to match, but I'm a bit doubtful now. unless I have missed something.
