1000cc P-P record - chains
« on: May 30, 2011, 08:36:28 PM »
Are any of you 1000cc girls/guys running 520 chain conversions?  Any real world speed increases from that?

P-P... did it come from the factory with that chain?  Don't remember it saying you can change the chain size, just the rear sprocket ... and of course the front if it is out of view.

You can run any chain size you want to, the fastest P-P 1000 bike runs a 520 non oring chain...the lightest/thinest chain you can run with nearly 200 rear wheel HP is the best for the application.  :cheers:

Any preference for Brand?
EK, DID, RK, TSUBAKI, RENTHAL. EK is probably the most expensive especially if you do the ZZZ type.

Where in rulebook does it say you can change chain size in the Production class?  Rule 7.E.1.12 states you can change rear sprocket but does not say you can change chain size.

Rule book states " any performance modification shall be out of view" Can you not see the chain on most Production bikes ?  We are putting together a 750P/P bike and if I can run 520 when it came with a 530 it would save me from buying sprockets. I have plenty of 520 sprockets. On our Norton production bike they would not let us run because we took the speedometer drive off the rear wheel. Had to overnight it in to bendover.  Removing the speedo drive is not a performance mod and it does not say you can not remove the speedo drive in the rulebook. Hey but we are from Texas what do I know.

I am confused by this Joe - a smaller chain size IS a performance advantage, and is visible. So are you expecting that an inspector would not be able to discriminate (visually) a 525 from a 520 size chain? Or an O-ring chain from a non o-ring? -Dean

Dean,

Another huge performance advantage would be to use a very small rider, viewable and yet legal..

Well sure John, but that has nothing to do with the bike. I'm talking about Production rules.

Joe, are you deferring to John's post, or Stainless'?  Sorry if I'm being dense...  Maybe I should just back away and not worry about this until it involves me.
