    Brinnelling damage from a chain too tight?

    I've always kept the chain tension within spec, and do check it fairly regularly.
    I like to think that the previous owner (Yamaha NZ) adjusted the chain correctly too.. but you never know :huh

    Just picked up a WR/R last weekend. Loving it. A bit surprised the pegs deck out so easily but perhaps this is the result of combing dualsport plush suspension with 17" wheels? Dunno...never had a tard before.

    Just ordered the 4.7 IMS, flatlands skid plate, GL coyote, seat concepts cover. Bike already has heated grips and a set of dirt wheels with fresh 95/5 Knobbies.

    Coming from a 950 SE....love this bike!

    When I saw the Wolfman Teton Saddle bags, they immediately reminded me of the Army's JSLIST bag. They're both made from water resistant nylon and have a roll top. The JSLIST bag has two shoulder straps that can be sewn together (or adpated for buckles) and draped over the seat. The only trick would be figuring out how to attach it to racks (bungies?). I'm not in a position to test them on my WRR for a few months, but thought I'd mention it for others that like economical homebrew solutions.

    FWIW, the JSLIST bag seems to be slightly larger:
    The Wolfman bags are advertised as 13" Width, 13" Height, 7" Depth
    A JSLIST bag is advertised as 17" Width, 16" Height, 8" Depth

    Does anybody have strong feelings about the best chain for the Yamaha?

    My last trip was a 2500 mile loop through Utah and Nevada from Phoenix. By the time I got back, my wheelbase was at least an inch longer than when I started due to all the adjustments. The last day required a chain adjustment every fuel load.

    The rear sprocket shows the wear with hooked teeth. Haven't looked at the front yet. The bike has only about 9k miles on the clock, but plenty of sand sand time, and I probably didn't keep it clean enough. I probably damaged it early in its life too by letting it get so loose it would jump teeth.

    I want to replace the sprockets and chain with a strong sealed O ring chain. It seems to me the chain should last about 15k miles. Any suggestions?

    My KTM is down right now.....had to redo some gaskets to get an air leak under control, which was causing a horrific lean condition..making bike un-rideable.

    So, since the KTM smoker is all brake sliding and clutch riding, I have actually adapted that style to my WR250R(4T), and broken myself of the habbit of relying on engine braking, and I actually think I am riding my WRR a little faster with that style.

    Can I "think" that I can go 100 miles with no worries on the stock tank? What is the longest distance guys are making it? Thanks

    Like most questions, the answer is "depends"

    Many guys here average about 55mpg, but charging hard on full knobs, I'm lucky to get 90 miles to the tank.

    It's just a cheap hard tail cruiser bike with a cheap 66cc engine......

    I bought it used from a guy off Craigslist and slapped some CORE stickers on the gas tank....I bought it on a whim as a CORE novelty/Joke......but I also bought it because it gets hotter than hell out at my vacation home in Bullhead City, AZ. .....I'm just going to leave it out there.... cheap rig to transport me to the river, convenience store, etc. in flip flops without breaking a sweat from pedaling a few miles......beverage in left hand/throttle in right hand

    You can snag engine kits for ~$150-200 on the internet: http://www.kingsmotorbikes.com/

    Here's a video installation tutorial on UTube: http://www.youtube.com/watch?v=UbKul89GGTU&feature=related

    I hit 28.6 top speed on the flats per my GPS .....so it probably hits ~35mph with a more reasonably weighted rider .....you simply pedal 10', release the clutch lever, and bump start the engine.....

    I figured you folks would get a kick out of it since I (we?) already take a bunch of crap from friends for riding a 250cc Dualsport as opposed to a bigger 400+cc bike......whatever........screw'em :lol3
