would you mind weighing your UR pulley? I'm sure with Josh's comment about UR not being truthful will want ppl to know the actual weight. thx

well i put it on my scale at home and it was too light to register. soo i weighed myself and then weighed myself holding the pulley and it was 1.1 lbs heavier. not scientific but that's the best i can do

Nice review, thanks for the link..

So, are you using the stock belt or did you have to get a new one..??

It's an underdrive pulley. Different diameter. Different belt. The belt came with the pulley.

good enough for me. thx :tup:

Kinda reviving the thread here...

Quick, simple, and maybe stupid question...

If I replace my crank pulley with an OEM size lightweight pulley, can I keep my stock belt or is it advisable to get a new OEM size belt like Gates for example?

Thanks!

You can absolutely use your existing belt.. but they need replacing anyways, so a good opportunity to drop a high quality replacement on there.

For the month of April, we're throwing in either the smaller belt for undersized or OEM sized for standard sized pulleys as a special. Free Gates belt w/Pulley Purchase.. FYI

PM me if I can help..

Josh, can you clarify step 3 on your install instructions? What is "the one of the angle mark"?
"Place a paint mark on the crankshaft
pulley (a) aligned with the one of the
angle mark on the crankshaft bolt (b).
Tighten the bolt until it has turned 90
degrees and the next mark on the bolt is
aligned with your paint mark."
