Chain/Sprockets Time

Postby Droldaerd » Wed Aug 16, 2017 3:56 am

Hey everyone,

Still running through my check list of SD990 repairs. In the process of selling my 1996 vfr750 and 1984 900 ninja to help speed things along on this bike. I'm loving everything this bike has been doing and there's so much more I want to do!

Next up, Final drive.

Ill be replacing the current 530, 17 front sprocket to a 520 super lite set with a 16 tooth front. I was thinking of going up a tooth or 2 in the rear or would that be too much loss on the top speed? If I change the sprocket sizes do I need a speedo healer?

You won't need a speedo healer as the pickup is on the front wheel.
If you're dropping a tooth on the front you shouldn't need to go +2 on the rear, unless you're going racing around a go kart track..

530?

I thought these bikes were 525 stock? Unless the PO had gone to a 530 set up? Also after 2006 I believe 16T on the front was stock, as pre-06 was a 17T front stock.

I have 16/39 right now and it's alright. But then again I've had 16/38 for the last 5 years, it's not a huge difference but noticeable. Lot's of people a 40/41 rear sprocket for easier wheelies.

Maybe its a 525. Just seems a little wide to me. Could just be use to the 520s on my bikes. I do a lot of canyon carving, 45 miles of my daily commute, and love cranking random wheelies off as well so I think I might end up on a 16/40 and drop one tooth in the rear if its too much for me.

Thanks for the post. Lots of good info there.

Awesome. I love not buying extra unnecessary parts! Also I don't find the ride very comfortable over 110mph and there's some guts still left. Along with the *cough* occasional wheelie, I think I'm gonna try a 16/40 set up first.

Well shit I ain't far from ya in Hesperia. If you ever wanna ride or want a hand wrenching lemme know.

What canyons do you mostly do?

Bouquet canyon? 9 mile? ANF? Cause I know the only canyons in Lancaster/Rosamond are 90 degree turns lol.

Definitely wouldn't mind a wrenching hand or a ride out!

I live in rosamond but commute to Montclair. Generally ill take the 14 to angeles crest highway. I think the end of my run, the T to Newcombs or back down the mountain is 9 mile right? I've done Azusa 39 a couple times on this bike as well just to kill time in the day.

Funny, I commute from Hesperia to the Upland/Montclair border for work. I don't envy you driving out from Rosamond ffs.

Yeah this is 9 mile: https://goo.gl/maps/M966bGsomy22

This is the route I normally ride for ACH: https://goo.gl/maps/NuVmnh89aGr I'd be more than happy to meet up around Mt emma meets AFH off the 14.

Defintetly especially after all the help!

Ya the ride is brutally exhausting when I hesd home around 3am.

Ahh that's 9 mile road. I've never road it. I always bypass past the fire department because I never have time to go to new combs. Never been.

Ive just ordered a a 530 DID chain and sprocket from Sprocket centre for my multistrada. i last put chain and sprockets on it at 20,000Ks, its now done 70,000Ks plus. and the chain and sprockets are still in very good condition. But I'm replacing the chain and from sprockets so i don't get caught out on a big tour ride. DID ZVMX, they are the best out there.
2005 640, full system, 18 litre tank, flatside carb. 2010 Black multistrada 1200 Ohlins-with SCU. 2016 1290 GT, Remus muffler and link pipe, Rottweiler plates, and dongles.

Anyone know if I can reuse my toothed securing plate again with the new chain, even for a little. I ordered one but probably won't get it for over 2 weeks and need to change this chain and sprockets like now!

Yeah I've done it. Just 180 the plate and bend the opposite end, that way your not bending fatigued material.

Awesome thanks! I figured. Have that on my 84 Ninja, just wasn't sure it was the same.

Chain all done! I know you super duke nerds love photos so I snapped a couple in between the repair.

Main issue. I was getting chattering at the front sprocket. Chain was almost at max stretch out. The chain clearance would vary depending on what links were on a sprocket. My crush washer actually had a broken piece and the nut was slightly loose but had locked on a pieces of the crush washer again. Lucky me. I had to re use it for now till the new one comes in next week. I had an oem stock 525 chain, 16T front, 38T rear. Changed to a "super lite" 520 D.I.D.50 ZVM, 1200cc rated, 16T front, 40T rear. Over all, I feel the acceleration is much more balanced. Before 5th and 6th gear felt a little stretched out. Bike cruises at 75mph at 5000 rpm and 88mph at 6000 rpm, 120mph at 8500 rpm while in 6th. So I'm perfectly fine with the new powerband.

Next on list... Probably new clutch plates. Mine feels a little sticky.

Only 12k miles on my chain. I did change the gearing to 16/40 and I like it a lot. Can you say clutchless 2nd gear wheelies?
I will keep in mind the 520 conversion. Or should I loose the 10lbs I've been meaning to loose?

While weight loss on the bike is definitely a benefit of the 520 conversion, there's more to be gained over the loss of structural integrity. A 520 sprocket system will require less energy to increase in acceleration and speed meaning more acceleration for the same energy input. Same will go for the chain and the effect is even greater because the chain links are constantly changing direction.

Now if you're a big boy like me, dropping a few will do wonders for acceleration/braking. I'm looking at a 7.5% increase if I can drop 50 pounds from my 250 pound self!

From what I know the damped drive sprocket is just a solid drive sprocket with rubber to dampen the chain noise as it feeds onto the drive sprocket, is this correct?

Correct.

I've ran two undampened and I've yet to feel a difference. If there is a sound difference my intake noise covers it anyways.

Pretty sure KTM puts them on (production) to minimize every source of noise for the TUV/EU/EPA etc., "drive by" sound test requirement. As you said your intake and exhaust covers it. The only way to "hear" the difference would be to coast the bike down a hill with the engine off with each drive sprocket in place......but then tyre noise and wind noise would come into play. :lol: I'm sure the little noise that it might minimize to the drive by sound test is the only reason for a damped drive sprocket.

Is there a 520 16T dampened sprocket available?

Don't think so. Got them from sprocketcenter.com

Went with 520 super lite sprockets.

Chain will have to be cut to fit.

With a 16/40, I cut the chain down to 104 total with master link.

It was a 102 on my previous 16/38 set up
