Highest Mileage TE/SMR 449 or 511

I'd like a winter home someplace it isn't 5 degrees and 2 feet of snow!

three weeks 130 miles today, on another wet oregon commute! needs a bath and an oil change now

A bit of a nervous nelly right now...bought this with over 10000k on it in January.. has yet to have a rebuild. I've had two SOLID rides on it, the first about 90 k of about 75 % road (to get to and from trail) and 25% fire roads. Second ride was a local property owner who had an enduro and moto track...about 2 hrs of fun. Had noticed that after this last session....was starting poorly so, popped the valve cover off and checked valve clearance. Found 3 of 4 valve clearances were tight/out of spec. No fooling around, bike in shop to have a good peek at clearance from their mechanics and a leakdown test. Able to connect with original ower who was absolutely meticulous and a valuable resource...anticipate shop will tell me a top end is needed. I have no problems sinking into this as the 2nd owner sold this at a pretty sweet deal and rode it minimally from the first owner. Going through a complete bike withdrawal right now though...gets looked at tomorrow. Better self-medicate with a beer...TBC

Thanks for clarifying Coffee...was ripping through all of the posts and fixated on 'highest mileage"

410 miles today!

7900+ miles here

No engine work?

None at all. I know it's naughty, but I've not even checked valve clearances Oddly, bike still runs as well as it did when I got it (no discernable loss of power noticed). I've just been performing regular oil/filter changes. Saying all that I bet my engine goes pop next time I fire it up!

Just 3100 kms on my SMR 511 and no problems yet. Checked the valves and they were fine. Prob won't check them again till next year.

Classic...target fixation!

Just thought I'd add FYI, that the maintenance section of the official Husqvarna service manual shows a rebuild necessary at 10,000 km (6200 mi). (new piston, con-rod, crank bearings, clutch, timing change, and valves(?) Not sure what "valves" mean. Maybe a head rebuild too?
The above data is for non-full power up setting. For "full power rating - racing use", the manual says 80 hrs! Yikes!

Every dirtbike I have owned had very frequent rebuild requirements. They almost always last at,least twice as,
Long with good care. I would bet some 511's will go 20,000 plus.

Yeah, I was just throwing that out there since no one else noted it. I'm sure that 80 hour number is for, as Tinken said "...you pin it for 500 miles across the Ca desert..." And I think 10,000 km is pretty reasonable number for a dirtbike.

That 80 hour measurement is worthless and that was before they upgraded the wrist pin spray bars. If you insist on running 50-60 weight oil in your 449, just plan on an early rebuild. Otherwise the thinner synthetic 40's will greatly extend your service intervals.

Bought my 2011 TE449 used with 2000 mi. Then had Zip-Ty racing do an extensive rebuild at 3200 mi.( see " has anyone seized a TE449 yet? " thread.) Hoping to get 1000s of miles out of it now!!

That means my bike will last me another 19 years !

We did a lot more than a rebuild. Your new crank shaft flows over four times more oil than the stock one, which not only cools the rod bearing, but also the wrist pin, piston and cylinder walls. Coupled with your new Zipty oil mod, yes, your engine is going to last you a very long time.
