Has anyone tried a 40 tooth rear sprocket? - Page 6

**jonathan180iq** · 09-22-2009, 02:22 PM

Your 15/39 combo gives a pretty low final drive ratio. I would think it's better than a straight 16T but based on what you say it sounds about the same. I still would have taken that chance and gone with the 40T rear instead.

39/15 = 2.60 (you)
41/16 = 2.56 (16T)
40/15 = 2.66 (40 rear) Allows a slightly faster "spooling up" than the 16 or the 39[edit]
41/15 = 2.73 (stock)

I thought you might be able to correct this slightly by going with a 14T up front but that would be even more "BUZZY" than the stock ratio. It would come out to 2.78

I read about someone moving the choke about 1/8 in fourth in the forum and it seems to help.
I tried it yesterday and fifth responded. I don't think I'll ever get over 70 with the plexistar fairing. I'm going to go to a bigger jet though anyway to help fifth a little more.

If you increase your main jet, don't go overboard. That is, don't get one that's TOO big thinking that "bigger is better". You'd actually make it worse by having too rich a mixture.

I'd try just one size up and maybe take that little lip scoop off of the air filter.
Anything more than that will probably be overkill.

Unless you totally remove the stock airbox and go with a pod intake system, there isn't too much "playing with the carb" that needs to be done.

With the 16T front sprocket I could still hit 80mph on the highway. You just have to know how to use the new gearing. That being said, it's well documented that the sprocket change isn't something that you do for top speed. It's for lowering cruising revs and making the "in town" gears last longer.

The more I ride it, the more I am happy with it. Your right. I just needed to get used to the gearing. All good now. I was just worried about getting on I70 and keeping up with traffic. Won't be going that route but once or twice a year. So no big deal.

That seems to be the case for most people with this bike. It can handle the interstate but it's not an interstate bike.
Most people who spend a lot of time on the highway ride larger displacement bikes anyway.

For what it is, the GZ is great. And the 16T front sprocket make it even more "cruiser-esque"

Ok, I found a solution to my woes. I bought a 750 Shadow Spirit. Fixed it immediately. I can go faster than 70 and the gearing is beautiful. Don't get me wrong though, I still love my GZ.

I now have a 16 tooth front sprocket (never used) and a 39 tooth rear sprocket (less than 50mi) available if anyone is interested.

That's the way to fix your woes!!!

Could you pull the 39?

Maybe I shouldn't mention this now but........a lot of the Shadow riders end up "adjusting" their sprockets too. Not possible, of course, if yours is shaft drive.

AND....you aren't too far from me; maybe we can hook up next summer.

What about 42-16? That would give you a 262 gear.

Yes we know. It is not necessary to flood the site with the same message. Just list the sprocket in "bikes parts for sale".
