Spring for Modified BSP 196cc Clone, Honda GX200, Predator 212cc and Yamaha F200 - Sold Separately
This is the preferred valve spring for modified GX 200 and clone engines that will need to turn a max RPM of 7500 to 8000 with cam/rocker combinations of valve lift less than .325". Not recommended to be used with stock valves, but highly recommend to be used with stainless valves and retainers. Higher RPM's can be achieved with shims placed under this spring, however, shims decrease the spring's range of travel before coil bind, reducing the amount of lift that can be run. ALWAYS CHECK SPRING COIL BIND ON EVERY BUILD

Only problem I had was I paid for 2nd day air and it took 4 days..
The springs work well, the fact I have to order them individually is dumb,
These 26 pound valve springs allow for more RPMs and go well with modified camshafts.
Will help you get in to, or even further into your aftermarket camshafts' powerband. WORTH IT.
ARC connecting rod strongly recommended.
Was previously running 18lb springs. Not only did they bind with my cam but they floated way too early. New 26lb springs solved both these issues.
What more can I say they're perfect
Put this cam in stock motor with 26 lb springs left the governor functioning b/c it's on my son kart its heavy so it needed a little more ump did the job perfectly
