I really want these, but near as I can tell, I can't change out the stock versions and still be AFM Production legal, which makes ZERO sense to me... not that it matters in the short term, but it might next year...

It's really strange that, with all that the AFM Production Class rules allow you to do, you can't change out a couple threaded plugs.............

I think I'd argue this one with AFM.

Section 8.1.1 f - specifically requires safety wired bolts with fluids behind them - oil drain plug is no-brainer.
Section 9.1.6 p - allows replacement of fasteners if no 'intentional' weight savings is gained. We're talking grams of potential weight here -

The overriding safety requirement rules would negate the miniscule weight loss with a new drain plug. The intent of 9.1.6 p is to keep guys from going full titanium for all their fasteners.


Sidebar: USBA allows Ninja 300's to run in 250 production class "as long as they are factory stock". What that really means is that you can replace bodywork and do typical race prep, but no suspension, exhaust or engine mods. Replacing a oil drain plug isn't even on our Tech's radar....

Yeah, I'm with ya.

I might just do it and if anyone cries bloody murder because I beat them due to my fancy filler cap, we'll see what happens.

EDIT: I bought them. :p

Looking forward to hear how the transaction goes. That guys feedback isn't exactly the best.

I should add, I know his feedback is above 99%. I actually read the reviews though. It isn't so much the response the seller leaves, but rather, the lack of responses on some of the transactions.

The eBay pages specified the drain plug as M14X1.5 and the cap as M27x3, so that's what I chose on the Moto-D site.

But yeah, the drain plug is 12mm long and not 16.

Oh well. I guess I'll find out if they're wrong in a few days ;)

I'm hoping those plugs are the right size for the R3.

The compatibility finder on their eBay listings says they are.

Is it too much to hope that at least ONE part is standardized across several motorcycles? Maybe so.

Not sure yet. I have the plugs but I don't have the bike (won't until Saturday). But Mr. Spears above says its 12, and so does the manual, so that's where my money is.
