I have a 06 450 wr and I was wondering how Reliable other riders have found this engine to be. If you could be so kind as to let me know what problems you have encountered with this engine and what kind of riding you do, be it street,enduro,racing. Maybe you might have a hour meter or odometer reading at time of failure or what is the most miles you have riden on this bike. thank you fellow bike riders. Dok

I had done over 10,000 miles of motard, dualsport, commuting and trail riding with my 2003 WR450. I purchased it new in February of 2003.

What a great reliable bike! I was very impressed with the power after I uncorked the bike - free mods, added a JD jet kit, and Yosh RS3 full exhaust.

The 2003 models did have a factory recall to check a possible starter woodruff key problem the affected a small batch of bikes, but my bike was checked and never had a problem. And it only required a single valve adjustment in 2006.

I can remember replacing the following maintenance items myself:

Front wheel bearings
Front brake pads
Rear brake pads
Chain & sprockets
Weep seals for water pump shaft
Battery

Sold the bike May of 2008 for $3,000 and purchased a "new" leftover 2007 WR450 for $6,000. The '07 with the aluminum perimter frame feels lighter and more nimble, but everything else is pretty much the same. I wish the OE gas tank was bigger.

have an 06 wr450, ride open desert in So. Ca. Have zero problems change oil every 200 miles and have only had to adjust valves twice. Only because the shop did it wrong after break in. My only gripe is wish had more range on stock tank and the way the chain slaps on the sub. frame.

the way the chain slaps on the sub. frame.


I have designed an aluminium/nylon guide to prevent this.
I'm having a bunch of aluminium plates plasma cut at the moment in preparation for manufacture.

They should be ready to begin selling in about 3 weeks or so.

They look neat, bolt right onto the swingarm, with no extra holes to drill or anything.

Watch this space! (I'll be advertising them here in Thumpertalk.)
I think they will be priced at $US50 plus shipping.

Sorry for the delay guys. I forgot to come back!

I have just begun production. I'll be advertising them in the Thumpertalk store within a week or so.
$US50 plus shipping.

A lot cheaper (up to 40% cheaper!) than other chain blocks currently available. ..... and unlike others this one stops chain slap to the left and the right!

Thanks for your interest,
Greg

Looks like you got yourself a good product there Greg. I never had the chain slap problem ( I don't over tighten my chain), but I know of lots of people that have it really bad and could use something like this.
