How long does a 520 last??

I have aset of Sprocket specialties 520 conversion and was told by the guy at the local shop it was going to need to be replaced in about 4-5000mi??

I had one on my 600 and it lasted fine for 4000mi, is he blowing me smoke or will it need to be replaced in about a year?

 

Im willing to bet each MFG is going to last differently.. Best bet would to be go directly to the sprocket MFG and ask them.. I know on my F4i I had to replaces stock sprockets at about 12k or so.???

 

Thats why I never do the 520 conversion!! Its gonna wear much faster and aint worth the gain.

 

I have a black chain that used to be gold...

 

get the chrome chain - adds 5hp

 

Alright!!!!:YEAH :YEAH If I add that to my sticker collection I'm looking at at least 8-10HP gain!!!!! :YEAH

 

i had a 520 on my zx9 that was at the track more than the street. 3 years later and it is still on the bike. but it is time to change it.

 

same

 

Cool, I was going to put it on anyway, just seeing if he was trying to smoke me.

 

uhh i am still running that 520 conversion you sold meh. im at 7k now dont remember when you sold it to meh. at least 3500 miles on it .

 

Damn, You ever put that undertail on????? I wish it could fit my new bike.
I got the same setup for the 1000 of the 520, going to install soon. You down in the area still for work??

 

i got prolly 12k outta the stock 525 on a 600rr and im still rockin the did inliner gave me and im over 16k, and its got lotsa room left..

 

nah the undertail went to ebay but ya still rockin the 520 kit only had to tighten the chain once since install.

 

Chains are something you wanna keep an eye on because when they break they slap your motor case......means new motor or alot of jb weld

 

Shouldn't the chain outlast the sprockets if taken care of properly???
