Standard pulley size for JRSC M45
 

Hi, can anyone tell me the standard nose pulley size that tha JRSC M45 kits come with, standard kit, not the big boost?

Thanks,

Jim

TDR has a good nose pulley RPM chart

Thanks for the tip, I have already been looking at that, I am planning on ordering new pulleys, but I want to know the stock pulley size so I know what ratios they run. I guess I'll just have to wait til my M45 arrives.

Sorry, I'd say that the stock is 77,5 mm. I can measure when I get to my car on saturday.

that would be great, thanks

Hi Jim!

As far as I could see, the pulley was 72 mm.

I always thought it was a 70mm. But then again, the first gen used like a 80 or 85 mm because the crank pulley was smaller. Depends what gen you have.

Sometimes it's a 72,5mm pulley (NA models) and other times (usually on NB's) 67,5mm. Hope it helps you. I have a NB and was looking for the 62,5mm pulley.

My kit arrived, it's for an NB, and has a 67.5mm nose pulley.

I'd just call Gary.
