    Led tail light on 2003 wr450f

    Not sure what you found for potentially replacing the OEM.... this one is a duplicate of the kit that was on my WR.... https://www.ebay.com/itm/1pc-Universal-Motorcycle-Enduro-Trial-Bike-Fender-LED-Brake-Stop-Tail-Light-LJ/112691598218?epid=24002982991&hash=item1a3cf1538a:g:dgYAAOSwdW9aM2X1:rk:11:pf:0

    Crank But Won't Fire

    Don't know if this applies to thumpers, but some FI bikes will "flood" if started and shut off before enough warmup. ECU thinks it needs to supply more fuel, so I'd say check the spark plug for being too wet, and if so, try cranking it with wide open throttle to see if it starts...... careful when it does start, WOT is a scary thing at no load..

    Chain snapped, broken case

    Have not looked at your year/model.... Take this for what it's worth..... I bought the new set of cases for the '08 WR450, and saw they were identical, so swapped out only the left side. Best check Partzilla or other fische site to see the part numbers for that year or range of years, which will/should tell you what fits what year. Then if you choose carefully what you get for a replacement case, you just might be able to swap one side. In my case, engine cases were same from '07 to '11. BUT, I couldn't find a used left case, that's the one that's in demand. You will still need the top and bottom end gasket sets, be sure to replace any internal seals and o-rings when you have it apart, might as well do water pump, etc. while you're in there..

    Chain snapped, broken case

    I did this job last year, the clutch rod bore had a crack in the upper part where the seal is.. full engine oil pressure up there... you're in for a case replacement. I couldn't find used left sides, so had to buy the set..... you'll need all the bearings for the left side at least..... not a cheap job. Read through this one, it will give you an idea what you're in for.

    Yamaha Tools

    For that kind of job, you should get the Tusk Crankcase Splitter and Crank Remover/Installer tool, plus the Flywheel Puller (a must have for the job). Not that much money and worth it IMHO. It helps to have a bearing press, the hot/cold thing works but you have to have bearings perfectly aligned for them to go in... I made a simple press with a piece of 1/2" threaded rod and various washers, plus use an old bearing race. PS - Tusk tools available at RockyMountainATV but their site is down this a.m.

    Yamaha Tools

    The Owner/Service Manual has a couple of pages of special tools with Yammie part numbers. There are aftermarket sources of similar tools that might be more universal at a better price...... as Steve said, what are you looking to do or what tool are you looking for... I'm sure there's plenty of us with certain tools we've bought to do a certain job, just ask.
  7. I used Permatex red hi-temp RTV gasket maker, the gray ok too, and ensure it covers the mating surfaces with no skips and only a small bead of it is necessary, as it will squeeze out. The red was nice, because you could see it. Once on, don't take too long (under 1/2 hr.) to assemble the cases. The Yamabond is perhaps better as it stays "wetter" longer. Yes to replacing the main bearings, others as necessary. I did the heat the case, freeze the bearing thing, a press is preferable.
  8. Well, wouldn't tell you it was there unless it was there, a whole page of it describing how.
  9. It's from the 2008 manual, which is same as my WR and the OP's. Sorry, I don't know if the valves are titanium or titanium plated stainless or stainless. But how would one get the best seating without lapping in the seats and valve faces?
  10. Are you sure? The service manual describes the procedure in 5-23, 23.
  11. Water pump is driven by a keyed shaft, it can rotate somewhat but should not spin. Replace the bearing and seals while you're in there, perhaps even a new shaft (there are aftermarket kits). Just me, but you need special tools to swap out a rod and even then you might not get it right..... get entire new crank, it comes with a rod all assembled.
  12. You should be measuring with a micrometer not calipers..... cams I bet are OK. Only you can determine valve damage, check leakage by pouring a bit of gasoline in the ports, see if it leaks out on the piston side. If unsure, Not a bad idea to buy OEM valves and have them lapped in. You can do it DIY, but not an expensive job for a shop if you take the parts in, they might touch up the seats. I don't think you need the second crankcase splitter tool.. The one I have (Tusk) will press the crank into the main bearings. The main bearings come separately you need to press them into the cases first.
  13. Sucks that you need a new cylinder....... shop around for piston/cylinder kits....
  14. Some math for you...... Partzilla prices for crank, main bearings, piston/rings, top end and bottom end gasket sets, $605. Tusk splitter and flywheel tools, $105.... add whatever else for top end, hope you only need to hone the cylinder. Other bearings should be OK but clean and inspect, as well as check all gears in there. You'll only know once you're in there if you need another $100 or so. You'll spend as much time on the new bike as working on this. Check out the new bike of course, but I think you're good as is for under a grand. To me a better deal than dealing with two bikes, blah blah.... your call of course, I'm good with that too.
  15. DEvil's Advocate..... is the other bike going to have as good an engine as the newly rebuilt one? OK just saw your reply...... still, I'd do some math.
