Anyone done this? Have seen it mentioned various places on the interwebs dealing with the Bolt.

Anyone done this? Have seen it mentioned various places on the interwebs dealing with the Bolt.

I looked into this, even going so far as to make some notes on my phone, should I ever encounter a likely pulley at an auto jumble or similar. I didn’t pursue it too much, as those who have done it suggest the difference is marginal at best (maybe a few hundred revs).

Here’s the notes I made though:

Front Sprocket/Pulley
SCR/Bolt has 30T front pulley
5S7-17651-00-00 (part no from Fowlers).

People swapping them for a 31T pulley from a Stryker (XVS1300 Custom in U.K.)
27D-17651-00-00

5S7 = 950 engine.
27D = 1300 engine.

Beware - front pulley from XVS1300 Midnight Star etc have a front pulley with P/N: 3DS-17651-00-00. Some suggestion this is also 30T, so of no use!

Key is to count the teeth - you want a 31T sprocket.

Ahh, I saw similar referencing the Stryker. Apparently an exhaust/intake, reflash, and 31 tooth front sprocket is supposedly the hot Bolt setup.
