Do you know how much weight that saved?
It had to be in the 2.5 lb range, and of rotating mass...which you already know is actually a pretty big deal, in terms of good small mods that really add up.
I think you're bike is the best Gen3 here for what you're doing, naturally aspirated.
I think you've tried and tested about every trick and weigh savings you can do, and provided everybody with Alot of good info.
I still don't have a Gen3 yet, but I appreciate the time and effort, and sharing the info with everyone, that's invaluable stuff in the mod sickness world...I'm a recovering addict...and relapse often...I have my beater 1k on the lift begging for money now, lmao

There’s almost 1.5lbs just in the rear sprocket. 2.11 lbs for a 43t steel vortex vs .7 for aluminum 44t vortex. An uncut 150link 520 EK is 5.5lbs on the nose (idk what a 530 weighs). It was an incredible difference on the snappiness of the throttle and down low acceleration.

I just try to do my best with making this pile fast I’m not a hardcore grudge racer so I don’t mind sharing all the mods and changes. I just can’t wait for boost haha

Steel 530 2.1lb

Steel front, alum rear 1.2lb

FWIW 150link 520 EK3D 5.5lbs. I don’t have a 530 to weigh currently, but the internet says 4.8lbs per 100 links so I’ll slightly guess 7.2lbs. So an educated guess says the 520 setup is 2.6lbs of rotational weight savings, minus links cut off for wheelbase, but I think at 64”(+6) I cut a whole 8 links off of the 150.

Great info, and around 2.5 lbs sounds right.
 
I have a Gen 3, and I am looking for a bit more zip off of the line. I rarely go on the highway, so sacrificing some top speed is fine. Has anyone +2 on the rear? I am wondering how much of a difference that would make. I owned a 1986 GSX-R1100 for 23 years, and I went down one in the front, and put the largest that would fit on the rear. I don't remember how many teeth it had, but it was big. The bike was a wheelie machine, and a ton of fun. I don't want to go that extreme this time, but like I said, I would just like more acceleration. Any suggestions?

A few of us are 18-44/45 and love it. Look up canans customs on FB or IG. He is a dealer that has the best prices around.
 
I think if you get a 120 link you'll be okay. Somewhere on FB there's a chart but my 18/45 on my +6 took like 135 links so I can't see. 120 not working.

My newbie status is showing... Perhaps I was incorrect in thinking that +2 meant two more teeth on the sprocket, because you state that you have an 18/45 with +6. Does the +6 mean that you extended the swing arm? Sorry for my ignorance. I do not intend on extending the swing arm, I just want to add teeth to the rear sprocket for extra low end power, and will be keeping the stock wheelbase. Therefore, I am looking for the chain size for the increased sprocket size of 18/45 for factory bike length. Thanks to everyone here for the help!

A +2 or a +3 rear sprocket(yes, tooth count) will fit with the stock chain, and have enough slack.

Yeah my +6 is the swing arm. Chains come in 120 or 150 link, and my setup needed a 150 cut to approx 135. So you on a stock arm not wanting to move the wheel forward at all sill be covered by a chain that starts at 120 link
 
Has anyone noted the rpm increases at speeds on an 18/45 setup? For example, in 6th gear, the factory sized sprockets (18/43) have the speedometer reading 39 mph at 2000 rpm, 49 mph at 2500 rpm, and 75 mph at 4000 rpm. I am wondering what to expect after the change...

Stock vs 18/45 Mathematically (removing speedo error which can be bad on our bikes sometimes, mines off by 8mph at 90)
2000 = 37 vs 35
4000 = 83 vs 80
6000 = 110 vs 104


This should be pretty close. In 6th gear its really not noticeable.
