Is this a quality 520 conversion kit?

RE: Is this a quality 520 conversion kit?
There are days when I take my bike to the track (twisty and drag) so to me that little bit on the street is nice. It's been proven that with a 520 conversion you can get a 2-3% increase in RWHP -- that is a noticeable increase. And I'll stand by RK being a good chain -- it's been used on turbo bikes by top builders for years with very good results. When a chain fails -- even crappy EK's -- it can usually be attributed to poor chain maintenance.

i'm glad you guys have had great experience with RKs.
must be a cali thing if you guys don't live around here...
they fail lots. the chains were either brand new or with less than 3K on them...bikes garaged and chain serviced weekly. had to, they were stretching.
as far as the 2-3% increase...where are the numbers? was the test done with a brand new 525 and then a brand new 520 or just an old chain before and after? i'm not doubting the increase, but would like the specifics of the test itself.
2-3% say on a 100 HP bike....equates to just 2-3HP...not significant increase at all...unless you're racing, etc...won't make much of a difference.

Factory 532 chain 8 lbs. Rear sprocket 2 lbs. Countershaft .6 lbs.
Total for factory drive 10.6 pounds.
AFAM rear alloy sprocket .6 lbs. Countershaft .4 lbs. 520 ERV2 4 lbs.
Total weigh of 520 conversion: 5 pounds for a total weight savings of 5.6 pounds.

You can't tell me that shaving 5.6 lbs of rotational mass is not going to make a difference [sm=icon_stickpoke.gif]
