530/520 conversion kits
this goes along with my other thread about sprockets. Some people like the 520, some people prefer the steel sprockets for longevity. Anyways I'm curious as to what everyone's using and impressions on various companies. I know I've seen some 520 kits where the sprockets are dropping teeth pretty quickly.
I'm just looking at getting vortex steel sprockets and not sure of the chain yet

And if I may piggyback this post. . . I am installing a 15T front, stock chain is still good, can I take up the one tooth drop with adjustment or will I have to remove a link in the chain? Thanks #09!

I did the sum of all parts ebay 520 conversion which comes with a steel front and Vortex,(crap), aluminum rear. The rear didn't last too long and looked like the English Channel when it was done, since changed to a Sprocket Specialist and has been NP since. The new x ring chains are plenty strong enough for our bikes, it'll be 2years of track days and occassional street rides,(with plenty of 
action), in June without much stretching at all.

so basically as long as you get a good 520 sprocket you're fine? and yeah that does make me wonder about chain length... I'm an utter noob at that and looking at chains things come in 120 links and I'm like ok... so does that fit mine or what? lol

Yes, get either a good hardened aluminum or steel sprocket and an x ring chain and you will be fine. I forget what stock length is as mine was longer for the 43 rear but I'm sure someone else knows. Also make sure you get the right length or you will need the tool or an experienced mech. to put the pressed link on. Don't use a chain that has the clip master link they aren't strong enough, pressed only.

Took the words right out of my mouth!
Some chains do not come with a specific # of links for bikes - ie, they will come with 110 links and you'd just have to cut it down. Always measure twice before cutting off links, though. A friend of mine didn't pay attention to which rivet he was removing and ended up one link short.
+1 on rivet-mount (as opposed to clip-style).
nuhawk, I don't recall whether or not that change will require taking off a link. At worst, you can install the new sprocket and then see if the chain is too long for adjusting.

well I'd be willing to bet with -1 on a new chain for stock length you'd be fine cause you have the ability to adjust using the adjusters for the rear wheel to compensate. if it's a difference of more then a few links then there's probably issues

I just read the Corey saga! Man, I just about fell out the freekin' chair laughing. Obviously a good guy! Not all of us could belly up to that and take it the way he did. The forum server puked after 23 pages but it was a good read while it lasted. I will add him to my supplier list although it doesn't look like he stocks much for VTR's. Great post, good grins, thanks!

I made my own conversion kit from these parts. Everything works great so far and cheaper than any of the kits I saw.

You shouldnt have to change the chain length with up to a two tooth total difference. (I have -1, +2, and the stock chain length)
cheers

can we confirm the top speed talk? -1 or +2 shouldn't, but -1/+2 should.... I know at least one of you tracks their bike and I remember a thread saying you topped it out on the backstretch of some track at 145 or something... Don't remember the gearing though

Here's an article about gearing from Sport Rider. Using this formula and using their figure of 80 inches for rear tire circumference (I didn't measure mine) I came up with a top speed of 155.4 at 9500 rpm for a Super Hawk with 15/43 gearing. That's a bit faster than the bike will go stock if the Hawk will pull that rpm in 6th gear with the 15/43 setup (and I suspect it will).

hmm... I calculated it out and was chatting with my buddy who said indicated his topped out at 160. Question for those running different gears? How does your top end feel? My friend has -1 front and said he felt almost like the top end was slower. Granted he was also following his buddy on a busa so that could've been the reason :P

I think that was me. that was +2 in the rear 530. it's never felt any top end problems to me. but I don't do any long strech runs to test it. the track was texas world speed way so your running the lengh of a nascar straight. I'm actualy going to be so a 520 15/43 conversion my self as I always ran ont of track before I ran out of motor so I'm going to be looking for som 45t and 46t for the rear too

Like I said in an earlier post, I like it with these gears and I don't think there is a top speed penalty and may in fact go faster on top. I never go that fast anyway. Others feel that it's a bit too revvy for a street ride and I can certainly understand that.

there shouldn't be any issue with top end since every gear should be shorter. I was having brain fart yesterday but unless there's something drastic that I'm overlooking, then there's no way you would be slower in any gear

It won't be any slower it just will raise the rpm's by around 1000 or so. That's the only reason I switched back to the 41 rear for the street but it's not bad on the track either. Before the Vortex gave out I used one for the track and the other for the street.
