I know you havent logged on in 25 days.... but you need to spend close to a $100 bucks for a nice chain on those raptors. Cheap ones will just keep wearing down. Atleast 1/2 inch or so of slack when your sitting on the bike. Probably comes to over an inch when off it. New sprockets too. They eat teeth after a while. Its just a beast of a bike bro....sell it before it takes you whole.

06 YFZ450 Mixxer pump gas stock valve 480. Cp 13.75:1 Barkers exhaust. Stage 1 hotcams. FCI no box. Sredrum 42. 07+ case/oil mod + 4hp 3tq. 21x12x8 7 paddle extremes. 25:1 klotz mix for racy odor.

If its built you may need a stronger chain no matter what. My 660 when I had it had the original chain for ever. Whenever I upgrade chains I always go way above and beyond. I'm about to order a ek mvxz chain or the new 3d. I don't like DID. If the chains I listed are strong enough for a 1000cc sport bike then the yfz or raptor shouldn't kill it to fast with proper maintenance.

PoPo in the making!

My raptor has about 1" up and down with no load on the bike. Hope that helps. Make sure the carrier is not moving. Good luck.
