anyone??? lol

 

does it matter if its an RR or an F4i when you're buying them? im on www.parts411.com and all i see it for is for the F4

 

yo mang...my RK chain lasted me like 2K and started to stretch...mah first chain lasted like 16K, but i was just cheapa$$ and kept adjusting it every week but the POS was jacked!

i may have just gotten a horrible RK or something....i now have a DID and it's been on for like evers mang! like...since 22K...so like 16K ago and still looks awesome!

 

1 other thing to think about on -1 front or + back is whether you want to shorten wheel base of lengthen...going -1 front = longer wheel base...so if wanting to bring front end up go up in back...

 

Well, today I went out for a long ride with the -1/+2 gearing. Gas mileage blows, but awesome power down low. In 6th, the RPM is almost exactly the speed. 70mph was 6900rpm, and this is after correcting things with a speedo.

So I am betting that my top speed is 135mph now, tops. Maybe I could redline with the lowered gearing, meaning a theoretical 140mph top speed if I had no head wind.

I was at 125mph and about 12,500 on the tach and had to back down as I was running out of road. But, max power is around 12,500 rpm and only being at 125mph at max power in top gear is kinda low.

I like the extra power, but I am undecided if I like it overall. I mean, there are times when cruising on the highway at 7500rpm to keep up with traffic is annoying, and it does bother me to lose 20mph on top. I might be better doing a 520 conversion with stock gear ratios and learning to just keep the revs up.

 

Anyone else ran an RK chain?? 2000 miles seems pretty ****ty to me.....

ok, i've just ordered my Vortex front sprocket off of www.vortexracing.com they're on a back order for a couple days but thats fine, am i going to have any problems when i get to the alignment on the back wheel?

edit: oh ya and where can i get a good rear stand? and how much do they run?

 

I ran the 520 RK chain on my 1000RR for 5000 miles with no problems. Chain and sprockets prolly had about 2-3K miles left in 'em. Went back to stock chain and sprockets for gas mileage. Sounds lame but geez I was only getting about 100 - 120 miles per tank. Had to fill up 3 times a week commuting to work.

I'm keeping the 520 -1/+1 combo for when I go to the track but running stock gearing on the street.

There's some pics on this thread of the sprockets: RK 520 chain results.

 

Chainstretcher,

What is the best gearing selection for an '05 F4i for street use, in your opinion?

I tried stock, tried -1/+1 and am now on -1/+2 and while I notice a difference in power and snap, overall, is the bike actually faster?

I mean, my top speed is now down to 135mph tops, and while I might have more snap when I hit the throttle, I am having to shift sooner and more often, so at some point, does it become counter-productive?

I reprogrammed the speedohealer, and in 6th, the RPM matches the mph. 70mph is about 6900rpm.

Thoughts?

 

I'm trying to install my 48 tooth rear sprocket. I have a 15 in front. Trying to do the -1/+2 sprockt change with the stock chain. It seems like the stock chain is too short? I cant get it on??? Please advise...Thanks.
