I was just wondering what other people suggest for a chain pitch for the F4I??

 

i'd say 530 for stunting.. its wayy stronger than 520/525
thats my

 

Ummm... not true!

 

So what one is good for stunting then??

 

525..works great.

520, just seems too weak....you have to tighten your chain more often...


who cares about the 1hp extra, and thats pushin it...

 

anyone else have any suggestions??

 

530 is the strongest.. if it's available, then why not?

 

damn... everyone says something different... anyone else...

 

525 is stock ... a lot of us run 520 ... 530 is something dumb people put on 600s

 

Thank you... I'm not even getting into this right now.

UOSTUNTER... there are about 9000 threads on chains around here. But unless you are stunting a BUSA a 520 chain IS MORE THAN ENOUGH!!!!! I stunted all season long on my 520 chain and I didn't have to adjust it ONCE!

 

525 or 530, I dont know why they make 520 conv. for streetbikes....very stupid

 

You're an idiot ... get your facts straight before you start chiming in!

 

do you ride streets???

wait till it snaps on the highway lifting a spreader up @60.....

seen it happen.

 

Almost everyone running Geared Steel has a 520 conversion - with no problems - most road racers run 520 too.
Don't overtighten the chain.

 

word....

i just dont trust it since i seen that ****...lol

either way i run 525.

does geared steel make chains too???
or just the sprokets.

 

They make the sprockets but the full kit comes with a chain, made by one of the major chain manufacturers. I've seen a 520 chain break as well - definitely scarey, but I've also seen a busa break a 530 ...

 

Yea, I rock the streets and I've never, EVER seen a chain snap in my life. (Both in the lot and the streets) And running a 525 isn't bad, I can agree with you on that. But E-Loc doesn't have a clue what he's talking about. And as Scott said, TONS of AMA riders run 520 and even 515 b/c of the difference in weight. Less centrifugal mass is key! But I've run an RK Gold 520 on every single bike I have had and they've all been tough as nails and I've done plenty of highway **** and so have my friends.

 

i run 520 and its perfect actually i dont think i have ever adjust my new chain that i have had on there for 6 months now. 520 is more than enough. but 525 is stock and thats fine also.

and i run one of the cheapest chains out. i run a parts unlimited brand 520 x-ring.

 

hey Farley why you so defensive?????? experience....ive broken high quality 520 chains on 35 hp dirtbikes in the dirt (far less demanding than street)....this is a place of opinions so why am i getting bashed??? I dont get it thats all.... heres my whole idea-you would save a pound and a h/p or 2 just to sacrafice a stonger more reliable chain. Tensile strength isnt just a number....remember that Richard.

 

You should realize how many highly educated people are on this site.

Since you want to go that route - The proper 520 chains are for bikes up to 1000cc. and have a tensile strenght of about 9,000 lbs. But guess what, many 525 and 530 chains have the same tensile strenght. Stepping up to the strongest 530 for bikes up to 1600cc. (drag race chains) only takes you up to 11,500 lbs tensile strenght.

As for your dirtbike chain - 520 motorcross chains are not the same as 520 street chains.
