Grayracer, this chain?

In process of ordering my new chain for my 06.

Regina 520 ORN6 O-Ring Chain 520x114

Or is it this one?

Regina 520 GPXV Chain 520x120

I had an the Regina ORN6 on my YZ426 and it was unreal. After the initial ride I adjusted it once in 6 months (riding every weekend).

Yeah, I know thats why Im buying one, I heard they don't rub agianst frame, cases, and are strong as hell! Just wash bike, lube, and its good.

I was just unsure which one, the ORN6 or this other one, the other one is more money, but I was unsure which one Gray said to get. Oh, the YZ450F is a 520x114 right? Or can I go 520x120 and just cut some links, don't matter?


114 links...but you can use a breaker and get the 120.

The Regina ORN6 is the one.

"Cutting" them can be a problem, though. O-ring chains really should be supported by the outer plate on the side opposite that where you're pushing the pin from. This requires an exceptionally strong pin press type of chain breaker such as the #805330 on This Page. This type pushes the pins out of both outer plates at once. Motion Pro makes one, but if you don't grind the pins down to the plate, it isn't anywhere near strong enough. Not even close.

What I do is to use the type 1 breaker, #805000, on the same page. The downside is that it pulls the inner plate part way out on the pin bushing, and the link has to be pressed back together with the same sort of tool you'll need to assemble the master link. It works out OK. If it seems like too much, have a shop install it. It'll be the last time your chain has to be removed for quite a while.

Okay thanks guys. One last question, if I get 114 link will I not have to cut any links off, and just put it on and ride? And no thanks on the offer, Im buying a lot of other things for the bike at the same time, so I want to order it all new and through this site.

If you stick with the stock gearing....just put the 114 on and ride.

That's what I do...

Im ordering new sprockets (Ironman). Im going to get stock gearing with them though (13/49).

Thanks guys!

      So I have a 2008 yz450f and I would like to add some LED lights to it to make it street legal. Mainly just a headlight and a tail light and turn signals if I need to (which where I live hand signals work).
      So where I need help is getting power from the stator to a battery. Wiring from a battery to anything else I got and understand and don't need help with (but recommendations are welcome). So my questions are.
      What type of power is coming from the stator. AC or DC? Will I need a regulator or rectifier? How do I wire something from the stator to charge a battery? What would that wiring look like? Would this stator work? Anything else I should know? Any help would be appreciated. Thank you.

      Alright so I’m new to the site so maybe this question has already been asked. I have a 2002 Yz426f and I want a new exhaust, it has the stock header and silencer and sounds amazing but I’d like a little more from it, I know I want the fmf power bomb header and am kind of undecided on the silencer, I see on fmf’s website that their silencer will add low end and slightly take from top end and the other way around but I’m looking for increases throughout rpm range. I do a lot of trail, hill climbs, jumps, and wheelies so kind of need good performance everywhere in the rpms. My question is what silencer I should get and the jetting I should get for the carb. Thanks

      2005 YZ450F, Athena Big Bore, Power Bomb, Q4.
      Ok.  Last fall after a decently hot day at the track, I noticed coolant leaking from the weep hole on my water pump after pulling into the pits.  Ordered an Athena re-seal kit, put it all back together and didn't really get a chance to ride it.  3 weeks ago, went out to the track, and after about 20 laps, it started leaking again.  Kept filling it with water to get thru the day, never ran anywhere close to dry or empty, jut a cup or 2 low.  Ordered a Hot Rods re-seal kit with bearing and also ordered a new w/p shaft.  Did it all again and got it back together, ran it, and as soon as it got to temp, it was leaking out of the weep hole again.
      So, what the heck am I missing?  I'm totally stumped on this one.  Is something wrong with my case cover?  Do I need to replace the w/p itself?  I'm feeling like I should've just ponied up for the Boysen in the first place, and now it's biting me in the butt.  Any help or suggestions is greatly appreciated.  Thanks!

      Alright guys, my 04 YZ450f runs fine minus some slight backfires when decelerating (need to adjust fuel screw). The other day when I was done checking my valve clearances I changed the oil and filter and put the bike back on the stand, kicked it a few times without the ignition coil in to get some oil flowing got off and noticed a little drip spot on the ground, it was no bigger than a dime so I thought nothing of it. Started the bike with no issues took it for a quick 10-15 min ride, came back to the garage to find out my whole case was soaked with oil and it started pooling in the low spots on the clutch basket side. I cleaned all the oil off and took it out again for 5 mins to try and see where it was coming from, here are my three possible places but nothing directly leads me to believe it’s any of the three either.
      1. Decompression plug area
      2.  Valve cover gasket leak (not really sure because the amount of oil leaking Looks to be a large amount
      3. Oil tank (bad weld or cracked weld somewhere
      what are you guys thinking?
