Going up 2 teeth in the rear?
@ 70 mph I’m turning 4,200 revs and @ 80, 5,000. If I went up 2 teeth on the rear sprocket would be revs increase more than say, 500? Also, would the 108 link chain suffice or do you add 1-2 links? Looking for a lil more ‘snap’.

I run a 45T on my ProLinks. Really wakes up the motor.

One tooth in the front is aprox. 400 to 500 rpms and make a nice difference. 2 teeth in the rear would do the trick!

Re: Going up 2 teeth in the rear?
I didn’t remember my other 82 being so calm in acceleration so I counted the teeth. Front has 18 but the rear has just 38! No wonder it’s kinda…calm-ha. I think I’ll try an OEM 42 to wake it up.

Re: Going up 2 teeth in the rear?
Had new 18/42 sprockets and a DID O ring chain installed along with angled valve stems today. Rebalanced the tires. What a difference in acceleration from the 38 tooth sprocket. Now (that’s) the hot rod I remember! I’m used to more modern faster smoother bikes since selling my other CBXs but I think this one vibrates more above 80 than I remember. I have a fork brace coming. I’ve never run Kenda tires that this one has. I sorta remember Avons, Pirelli and Dunlops. What’s everyone running these days? I like a sticky tire but I’ll also be touring.

I've been running and recommending Shinko Tour Masters. Usually 1 speed rating higher than most. Economical too.Dynamohum wrote: ↑Thu May 30, 2024 7:21 pmHad new 18/42 sprockets and a DID O ring chain installed along with angled valve stems today. Rebalanced the tires.

Re: Going up 2 teeth in the rear?
I've run both Shinko and Kenda. Good tires both. That 38 was definitely not a performance sprocket. As for vibration, check tire balance first. Then, look for runout and alignment. My experience says a fork brace does nothing for vibration. Something is either out of balance, not square or not round. OR, loose! (Including headstock)

That looks nice. Bias ply or radial?CBX-tras wrote: ↑Fri May 31, 2024 8:47 amI've been running and recommending Shinko Tour Masters. Usually 1 speed rating higher than most.

I've been running these tires exclusively, they are outstanding. Great grip, wet-weather performance, long-wearing, you name it. Round profile that I prefer for smooth turn-in. Outstanding value.

Bias ply or radial? Their own website doesn’t say. Should say on the sidewall?

Re: Going up 2 teeth in the rear?
I just inspected one of mine, no mention either way, but I am 99% sure they are bias ply.

Thanks.
And @daves79, all I did was casually ask a question

Chill - it's been 'casually asked' a million times. We encourage everyone to use the search function to avoid endless repeated answers. But carry on!
