    Guys,

    Went riding this morning and have a upcoming trip too. Have some Kendra 270's on the front and rear and they were not any good in the sloppy stuff. ( sand, mud and hill climbs.) I need a great " all Terrain" tire. I'm not worry about wear on the highway as this bike is mainly for advrides and trail rides. So what do y'all suggest. I was riding really wet muddy trails today and the front had 0 control.

    I haven't read your first post with too much detail, but once again, your battery has NOTHING to do with your bike running. Provided nobody changed this, the ignition system is completely isolated from the your battery or ANY other electronics on the bike.

    (not considering the wiring job done and grounding, etc.)

    Maxxis DESERT IT's. (not the standard ones).

    Not DOT though, nor will they get the mileage teh 270's do. People call them worn at different "rates". Ie, on my trip I did 9500KM's on the rear... trying to get the treads to show. Baja was 4000km's and they were pooched. You can expect a few 1000KM of good service though. (1.6KM/mile).

    I haven't tried many tires, but they are way better then Pirreli MT-21's and last just as long.

    Anyone here have regular contact with Diane an Precision Concepts? I ordered parts in October and they have yet to arrive and emails are never answered on both addresses they used previously. Being in Australia makes calling tough, pm me if you can maybe help contacting her, cheers

    Out in the NM Dez somewhere
    I found the same thing, the Dez ITs worked way better than the MT21s, we ride allot of rocky desert terrain that likes to chew up tires quick, the Dez ITs are my preferred tire, they seem to hold up to the 650s pounding and the fronts stick pretty good. I chunked the only rear MT21 I ever had in 3 rides, I tried their front and it dumped my ass more than once. They just don't stick well in our terrain. If I'm running allot of road like a big DS ride I'd put on a 606 (rear only), they don't chunk and hold up ok riding pvmt but don't have the off road traction of the ITs.

    In the process of going over everything. I adjusted the valves today, they were all within spec, but I moved them to the looser end of "within spec" just for peace of mind. I adjusted the compression release cable since it wasn't actually working before so starting wasn't nearly as fun. Someone earlier had asked what my spark plug looked like. I'm not very good mechanically, I'm learning this stuff as I go along. Anyone see any problems with this?

    I cleaned the air filter, next plan is to tackle the carb to check things out, then change the oil, then see how motivated I am to do anything else instead of going out riding.

    Nope, all top end work can be done in situ.

    It's not great. Lots of carbon and appears to be a worn electrode.

    I'd consider adjusting your jetting and putting a new plug in. That much buildup could/is likely oil consumption too.

    Yeah, I'd planned on putting a new plug in. I'll see what's going on with the jetting. I haven't seen a lot of spark plugs before so I don't have much experience, but this does seem to have a lot more carbon build-up than the others I've seen.

    I really hope it isn't burning oil, I've already had to deal with one bike burning oil that turned into a nightmare.

    When was the plug last changed?

    Just keep an eye on oil level. See if your buddies see puffs of smoke under hard acceleration, etc.

    These bikes are pretty tough.

    Make sure to brief yourself on how to check the oil. Sounds stupid I know, but a lot of us started out by over filling our bikes.
    Basically, just take it fo spin around the block before you check it. Do not start it and run it for 1 minute and shut it down thinking its good, because it won't be. Also, with the bike sitting on the kick stand, it can never scavage all of oil from the case.


    Warm weather in 3, 2, 1, awesome weekend ahead. Hopefully the doctor doesn't tell me I am off the bike for rest of the season.

    That one is worn out and it looks like it wasn't fully tight, close, but not fully...that's why the threads are black.

    Check for a stuck open thermostat, it will make the engine run too cool and cause carbon buildup about like that.
