No, I've read on at least 2 dozen threads of people doing this and end up raising the overall top speed and lowering the rpm's in 5th gear by 750-1000. While also getting better highway fuel economy. The stock 883 has plenty of power to use a 29, 30 or 31 tooth pulley as long as you don't let the rpm's get too low. It does suffer in the low rpm's though. Several people on this forum have been running a larger pulley setup for 3+ years of riding.

 

Taller gears in a 45-50 hp 883 may get to 105 in 4th gear, but when shifted into 5th it will probably lose speed. It does not have the hp to get near rev limiter speed when used with taller gears.

I don't want to get in an argument and ***** this thread up, but you might want to do actual research about it. I'm not giving an opinion. The FACT is, numerous people have used a larger transmission pulley and achieved higher speeds in 5th gear at lower RPM's. You say that it "probably" will lose speed when shifted into 5th gear, so its abundantly clear that you didn't even bother to Google this topic. Aside from this forum, there are a few vendors on this site that sell larger transmission pulleys for the 883. You might want to ask them why they all claim the same results I am. At this point, I'm sure mattyj724 got his answer.

 

Keep twistin' that throttle dude, it can take it...

It does not have the hp to get near 5th gear rev limiter speed when used with taller gears.actually he is correct, I have a 883 (now converted to 1250) and when I changed the front pulley it lowered the rpms at any given speed (this was before I went to the 1250 changeout) but it didn't have enough HP to make it go faster and it took longer to get to top speed...also it went faster in 4th gear than 5th ..so lets say you wound it out in 4th you could get to around 95mph, and you tried again but shifted to 5th around 70 or so, it would have a real hard time getting to 90...my bike is a carbed bike so fuel injection may make a difference, but from my experience the guy is correct..

 

It doesn't much matter whether or not you have an 883 or 1200. At the upper end of highway speeds, we're all looking for a 6th gear. Both engines feel they are running short of RPMs at those speeds, but the EVO engine doesn't mind the RPMs at all. It's us humans who feel uncomfortable, hence the wish for the 6th gear.

 

THanks for the answers. i feel better now. she does scream at 70+. i wish i could just make 5th gear a little taller with the rest the same! Again thanks

I've just read waayyyyy too many posts about it and you two are the only ones i've seen who say this. I'm glad however to hear someone who's actually done the research and has had experience with it chime in. Still, most people experienced a higher top speed in 5th gear. Having said that, I never said it would hit the rev limiter in 5th gear, I only said it would lower the rpm's in all gears. That is, of course, what this thread is about. Is it not?

 

[quote=dtaylor00;11234953][quote=mrfikser;11234776][quote=dtaylor00;11234355]OK Sarge, question? Do multiple runs on the salt at Bonneville (you know that place where you run WFO) qualify as research? My experience/research is that a very well tuned stock 883 (hp~50) will just barely tickle the rev limiter, 109mph, in 5th gear and that is with a three mile run-up. With higher gearing, it wont come close. A very well tuned stock 1200 (79 hp), it has higher gearing, will not come close to its rev limiter (127mph) in 5th gear. Best I ever got was 120.6.

You also confuse me with "higher top speed in 5th gear" vs "hit the rev limiter in 5th gear". What is the difference???

You are correct with your implication that you will have a lower rpm at 70-75 mph, in 5th gear with taller gearing.
