Thanks Swamp but I don't think that's the case. Before I bought the used 2006 TE250, I test rode a 2010 TE310. The suspsnsion felt completely different. The 310 had much more sag under its own weight and then when I sat on it, it felt soft and but didn't seem to suddenly stiffen up at one point. My 250 is not as soft and the suspension feels stiff after going down maybe about 10cm (which would be a normal = acceptable sag with the rider on board). It simply seems extremely hard at that point. Is it normal with these bikes (a 2006 TE250)?? Maybe it's the suspension characteristics - I really don't know. That's why I'm aksking. I don't know the bike's history so if the shock needs a rebuild then I'll understand. One thing I know - it stiffens up in a weird way but it's far from bottoming out. I checked the spring preload and messed with the compression and rebound settings and the shock reacts to the adjustments like it should but even with almost no spring preload and low compression it still seems to get crazy stiff pretty fast. As for the carb, the described (or poorly described) problem does not have much to do with the jetting (I think...). The bike loses gas and there is a bog at the low revs when the throttle is open. Seems to me like the float level is too high and it floods the engine when throttle is whacked open at lower revs and causes the gas spills. This is the first thing I'm going to check tomorrow. The bike starts fine, idles ok, revs ok, rides ok, but when stopped with the engine not running, after you shake it to the sides, there are small gas spills coming from one of the hoses. This makes me think that the same happens while riding offroad. Not good. This plus the bogging makes me think that there is too much gas in the float chamber. Thanks for any help you might be able to provide. I've only had the bike for a week or so and I'd like to get it to run fine.
