NST pulleys

[raygenjay]

I finally replaced the front crank seal this past weekend. While I was at it I also installed the nonstop tuning crank and water pump pulleys. The job was easy and I have to say that there are no abnormal vibrations at any RPM. The machine quality was perfect and the finish was flawless.

they are not underdrive just lighter.

Do you notice any performance difference? How about charging issues? I’m thinking you must’ve needed a different length belt from stock as well, correct?

They are not underdrive pulleys. They are just reduced weight, I didn’t want the charging issues. I have to say performance wise, the runner is a little more throttle responsive. The main reason I bought is because I got a really good deal from NST and at 150k the crank seal wore a groove in the pulley. It wasn’t bad but a stock pulley is way more expensive. The machining is excellent, the fit was perfect, and I am really happy with the performance.

I am running the stock belt. The crank pulley looks smaller but it is not, they just use less material.

Ok, that makes sense. Thanks for explaining.
