I want to move my bike up to a 17t front sprocket (most of my mileage is on the road vs off road). I ordered the sprocket and went to install it yesterday. As I dove in, I realized the clutch is "in the way" and the tension is pretty high. I was worried that I might cause damage if I forced it out of the way.

Curious if there's anyone in the SLC are who's done this change and would be willing to walk me through it. Alternatively, I can post to the tech forum and get help, but it'd be nice to meet another 'Strom owner face to face, to boot...

Thanks in advance

You need to unbolt the clutch activator so you have proper access to the counter sprocket nut. Put a 2x4 (or equivalent) through the rear wheel to stop it from spinning and use a breaker bar to loosen the nut. Unbend the safety washer from the nut faces before wrenching.
Use red threadlocker when re-assembling.

I went one up on my strom. If your 17 sprocket won't fit for some reason, i have a rear sprocket suited for highway travel, think it's 43
I'm in the 9th and 9th area of you need a hand.

OK that totally helped, thank you - I though originally that the clutch assembly (the part that rotates and pushes the clutch in) was attached to that rod. I pulled the two 10mm bolts and the assembly came right off. Of course, I think learned that my 31mm socket is 1mm too small - looks like that's a 32mm bolt over the front sprocket. Emergency call out to the neighborhood Facebook page ISO 32mm socket.

I have a longish road trip planned Saturday (a buddy from WA is coming through and I get the morning "off" to ride with him a ways out toward Ely and such), I'm hoping to swap this sprocket out tomorrow after work so I can pull my RPMs down a bit at highway speeds.

Thanks again--always nice to have a little help working through that initial worry. ;)

I have a couple of sockets in the ~35mm neighborhood if you want to try them. Usually when the nut gets that far above 1" you don't really need an exact match as there is still a ton of contact area even if the socket is a few mm larger than the nut/bolt. Always worked fine for me even on VW axle nuts at ~250 ft-lb.

Sorry for the delay - spent the week at Black Hat/DefCon, and then the following week catching back up. I have the right sized socket, now I just have to figure out how to bend down that washer so I can remove it.

Seems relatively straightforward from here, no? Flatten the washer, loosen the chain, crank the nut, remove the sprocket, install new sprocket, tighten the nut, tighten the chain, bend the washer (in another spot). Am I oversimplifying?

I usually use a hammer to lightly tap a flat screwdriver between the washer and nut to get it started. Then the screwdriver can pry open a bigger space. If I'm being lazy I'll just turn the screwdriver perpendicular to the nut and finish off flattening in several spots. If not too lazy to find another tool, then a large flat tipped punch will leave fewer scars on the washer. It doesn't necessarily have to be perfectly flat before you can remove the nut.

I'll keep bent part at top, somewhat bend straight with screwdriver, then finish flattening with a socket extension.

Thanks guys. Now that I've mowed, moved one ceiling fan, installed another, and knocked off several other "honey, do" list items, I *think* I can snag a couple hours tomorrow to give it a shot.

I'll keep you posted. Meanwhile the 17 tooth sprocket makes a good looking paperweight here on my desk, LOL.

When I discovered a replacement washer is only $1.78, I added it to my Partzilla order (I have a number of missing fairing clips as well as a stripped bolt). Which is OK because I realized after pulling the bolt that I'm out of red Lok-tite, so I need to tear it apart again anyhow.

Thanks for all the help. I was thrilled to be at 5500 RPM at 70 MPH - and then I realized I still had another gear to go! Highway speeds at 4400-5500 RPM just seems like a dream, and best of all, "I Did It Myself (TM)" (well, with a lot of help)
