Chain and sprocket re-do

Well, it’s that time. My chain is old and

Stretched out. Time for a new one. While I’m at it I’m gonna go with new sprockets as well. Just wanted. To see if there is a consensus on tooth count front or rear. Stay stock or is there some untapped power somewhere. Personally I feel like the power is good too to button. Low end, I can get the front wheel off the ground, top end… do I need to make 135mph easier. I don’t think so??
But I had to ask you guys.
Also I see they also sell a front sprocket with like a hardened rubber core. Anybody use one of those ? I’m assuming less vibration? But at what expense.
I look forward to your reply’s

Thanks

Oh yea. And it’s a ‘94 VFR750

Some sprockets just have rubber vulcanized to them to quell noise from the counter shaft and gears. The same reason some VFRs have rubber plates bolted on the inside of the crankcase covers. The more Honda could reduce those mechanical noises, the more noise they could have in other areas, like intake.

Some people use and swear by them. I could give a shit, I wear ear plugs.

I personally don't want a true rubber damped c/s sprocket if they are out there, the rear hub already has 5 or 6 dampers. I own VFRs, not a Pacific Coast.

 

Good points Captain. Don’t want my vfr to get any softer that’s for sure.
In reading around I hear adding 2-3 teeth at rear socket helps low end pull without sacrificing the top end to much…
I may give that a good just for the heck of it.

This will help with your sprocket selection.......

avoid alloy rear sprockets as they wear out quickly.

 

Thanks guys. I ended up going with the stock sprockets and chain kit. Much smoother when getting on it and quieter. I needed a chain verrrrry badly

Hmmm I wonder what’s next. I’d love to go with all new exhaust but good ones are $$$$
We’ll see.

These 2 statements are very contradictory. You're concerned about some noise around the counter shaft but then you want a complete exhaust.

 

It's too bad Ognibene doesn't make their Silent Drive sprockets for the 800 vfr's, very nice stuff and you can get it in 520 conversion. I'm sure they could be cross referenced, I did that for the countershaft on my RVF.

 

When I installed the 520 conversion on my '99 I went from the rubber coated sprocket to just a regular
one, and couldn't tell any difference in noise level. It may be louder, but couldn't tell over the gear whine
and exhaust sound.

 

I only do the countershaft sprocket. It's typically during coast down that you will notice it. Anytime I have had a knackered sprocket, I can feel it it before I hear it.

 

Well…
A chain slapping/ kinking is bad noise that nobody appreciates.
The exhaust note of a full exhaust on a VFR, is heavenly.

I’ll take the louder exhaust over a noisy chain any day.

So I guess the rubber is for a smooth feel. Rather than to quiet it? Not that chain and sprocket make that much noise to begin with….

I couldn't feel any difference either, but I'm thinking it's for noise abatement. The stock exhaust is really quiet, and you might
be able to hear a difference with a stock exhaust. The gear-driven-cam engines are pretty noisy, so anything that would help
get them to pass governmental noise regs would be welcomed by Honda.

 

It's strictly for noise abatement from the transmission. I've actually had to grind it off of one side of a sprocket to clear a raised seal lip on the 1000R. I can't hear or feel any difference between bare sprockets or the ones with some rubber vulcanized to them, but I also wear ear plugs EVERY ride.

It also allows them to "spend" slightly more noise in other areas and still pass noise regs.

No shit a nice exhaust sounds better than a worn out chain and sprockets. You know that's not what I was eluding to.

 

Doesn’t sound like these rubberized sprockets don’t do much Other than convince riders spend more $$

No, I guess I’m not aware of what your eluding to??

Y'know.... I dont think I do either. : /

Killer bike, enjoy the new hardware. New chain and sprockets feel awesome. Its so easy to forget as they slowly degrade over time.
