2011 yz450f advice on break in period

Recommended Posts

So i just boutght a 2011 yz450f the white and black one its an amazing looking bike..the thing is that i've owned many bikes over 30 bikes i'd say and most of them were 4 strokes 450'fs but i've never had a brand new bike before so i dont know to much about the break in period. does it mean that i gotta ride it like if i wanted to win last place on a race.. and after the break in period do i take it to the shop to get it serviced or can i just do the servicing on my own and if so what would i need to do to it.. also how many tanks of gas or hrs on bike should i put before break in period is up.. also i bought this bike bieacuse yamaha is know for reliability but i just dont wanna start on the wrong foot

Forget the owners manual. Run it. That nikasyl bore coating is SO strong. Give it a heat cycle or whatever before you head to the track, Then do a sight lap or two half pace, then just run the thing ilke you stole it. Exactly what I do with all my fresh motors, and on my first new 2011 kx250f, and the way my friend broke his 09 and 11 yz450's in. When it comes to motors he knows his stuff, he works at a machine shop and fixes all sorts of grenaded motors, actually where the local dealers send all their heads for valves jobs.

Edit: Oil change. Change the oil after your first ride. Just helps to insure that any burrs or anything on gears in the tranny that come out dont go floating around. Change the filter too with the first change.

My personal break-in procedure.

Check oil, check air filter, tighten bolts, adjust controls, new petrol, warm up, ride it like my brother left HIS new bike in my garage (no lugging, no rev limiter abuse). Stop every 15 minutes or so to recheck/adjust/let bike cool down, repeat for a tank's worth.

Tear down bike for greasing and extensive maintenance. Then back out for more riding.

I was sent to this link 4 years ago when I bought a new street bike, and have used it on every new bike/rebuild I have done since. The "motoman" really was obsessed with flashy HTML code, but his methods have been solid and treated me well. Just don't forget to change that oil ASAP and frequently in the beginning...

      Selling an FMF Power Core 4 exhaust system off my 450FX. Exhaust has 80 hours and is 100% functional. This will also fit the 14-15 YZ450F and 16-18 Wr450F. If needed I can also include new muffler packing although it does not need it.

      I have a 2008 YZ450F with a stock header pipe and Pro Circuit T-4 Slip-On Exhaust. I'm 99% sure the slip on is shot because its loud as hell and when I take it off and shake it it rattles. I would repack it but the screws are all stripped ect.
      Anyways I've gone over the carb multiple times and I've got it running pretty well. The only issue I have with the bike is that it sputters and pops around 1/2 throttle when I hold it there. When I give it full throttle from any RPM it runs great or when I give it about 3/4 throttle it spins up like a top to redline.
      Initially the popping and sputtering was way worse I made the situation better by moving the pilot jet up in a few sizes from a 45 (stock) to a 62. The issue has gotten way better since then but I'm not super sure what to do from here. Should I keep moving my pilot jet up in size because that's a pretty large jump right? I tried changing my needle clip position but that didn't help much if anything it just made starting it worse and little to no impact on the ride.
      Any input on this would be helpful. I don't want to buy other slip on. Also as for the rest of the carb I'm very sure everything else in it is what it needs to be at. I've replaced all the gaskets and O-rings cleaned all the jets, valve holes ect. fixed the accelerator pump timing. I just thinks its strange that my pilot jet size is going so far from the stock 45, but all symptoms point to the bike running lean.

      Hi I was wondering if y’all have been using a 450 on your YZ250F?

      Excel Takasago 17x3 front and 17x5 rear supermoto wheels with Metzler M3 tires in very lightly used condition. Less than 200 miles total on the setup. Warp 9 spokes. Rear has a Talon hub with 45T Sunstar steel sprocket and OEM rear disc, and front has a polished OEM Yamaha WR450F hub (for the stock speedometer), with a Motomaster 320mm disc. Included is a DID gold o-ring chain, 14T front sprocket, and front brake caliper adapter for a truly turn key setup. Everything is in excellent condition, not a single scratch on these wheels. Came off my '11 WR450F, but will fit many different Yamahas with 20mm front and 22mm rear axles. Asking $1400 plus shipping.
      **Will be driving up near Atlanta, then to northern Louisiana, OKC, and down through Dallas and Houston, TX soon -- can meet or deliver if in the area (Aug 31-Sep 9)**
