Does anyone know where to get the smaller upper pulleys for the 525sc,thanks for the help

What size do you need?

I'm looking for the 8 pound pulley,i actually need three of them,any help would be great,thanks alot

New Merc style ones are no longer made by anybody that I know of. Gonna be very hard to find 3 of them.
You really don't gain that much with them anyway. Maybe 20hp.

Thanks griff,I already did the roller cam upgrades,figured if I could find them it's a easy upgrade,I read some of your threads on the 525sc,the pulleys would the last upgrade,as I know the little blower is at it's limits

looking for top pulley if anyone has idea where i can find it let me know!!!!

Assuming. You already called the blower shop?

Don't waste your time on the pulleys
More noise, heat and will lkill the blowers.
I tried those on my twin 525SC's and picked up 1mph

8/71's would be best money spent.
