Something else is going on - if you overheat the brakes, they still shouldn't lock up, everything should just go mush. My bet is the backflow port on your MC is clogged, so as the system heats up, it expands with no where to go, slowly completely applying the brakes. Either that or you have a really bad stuck piston.

Silver posted:Ah ok, yeah didn't know that boiling over - lose brakes. Yeah mine get really hot and lock up. I just rebuilt the rear master so fluid is new basically. I adjusted them before this and it did it, so then lowered the lever and it did it again, might have to just lower it some more I guess. Thinking I'm just dragging my toe when sitting and it's causing the brakes to overheat. When they lock up the rear disk and whatnot is hot as poo poo. I'll adjust again, would like to find a good middle ground as before this was happening and the reason I adjusted was because they were fine when sitting but when standing I have to really stab deep with my toe to get on the rear brake. Trial and error. Did you rebuild the MC yourself or did someone competent help you? I'd wager you've got caliper issues.

Neighbor helped. He's a full time mechanic and old school long time motorcycle rider/mechanic. Works well, I fix his computers and he comes over and helps me work on bikes when I'm not sure what I'm doing. Brakes have locked up once before after adjusting pedal on my first race, then readjusted but it felt to low, readjusted again and started locking up. Still thinking I'm dragging my toe causing the rotor to heat up because time before last when they locked up when sitting down I kept my toe out and not over the brake and it was fine. Wondering now if I might have warped the rotor which is rubbing the pads and causing stuff to heat up. Going to bleed the brakes too before I go ride next.

I went out for MX practice yesterday and had a new weird dirtbike problem! It bogged down a couple times, presumably because I was low on fuel, so I filled it up. After filling the tank it started bogging and stalling in right hand banked corners. I couldn't reproduce the problem by turning right on flat ground, or tipping the bike to the right, but every time I got into a berm going right it would cut out. Sediment in the tank or a clogged fuel filter are pretty much my only ideas at this point. Also, I got to ride Gullous's new 350SX-F and holy poo poo it's awesome.

I hope you resolve that issue, Zool! Here's a quick clip of me riding the 350. I had a minor case of whiskey throttle when I cased a triple. https://www.youtube.com/watch?v=w9RLw3uLwGA I still get pretty bad arm pump after a few laps. Besides exercise and stretching, I think 'm not gripping the bike with my legs as much as I should. Something to work on...

Went downhill mountain biking at Mount Snow in southern VT on Saturday and spent most of my time on the double black diamond shown here: http://vimeo.com/98672378 I've never done this before but I felt right at home. It was a really fun experience. Got lots of air, and had some great flow. My knee is feeling better and better these days. I do about 20 miles per day of XC mountain biking to try and strengthen it. Might be a bit premature, but I'll return to racing at the Rocky Mountain weekend in Alton NH in a couple weeks. Might just race sportsman though.

Hey guys, the KTM is back! But not for long. So it turns out that the woodruff key that keeps the flywheel in place was slowly shearing off, and slowly ruining my timing. Then it completely failed, and the bike wouldn't run. Got a guy to fab up a new key, and off we go: https://www.youtube.com/watch?v=KSoXu89TuSw Sweet! Ordered some new tires, and in the meantime went out to shred whatever is left of the old ones. First, the kickstarter cracks and is completely unusable, then the key shears off again and strands me. I can't say enough how lucky I was to be in a group this time, and close to one of the road crossings. So my brother and I went off to get the trucks, only I now must mount my lady's mighty kx100 steed: http://youtu.be/t77jzNdrMCo That thing is super fun So anyways, I ordered a new kickstarter/key, and once I get this bike running I'm selling it. I know everyone has had great luck with KTM's, but both that I've owned have just been awful, and I've spent way more time loving with them than riding them. My $1000 RM250 has been way more reliable, and it's a 96! So I'm shopping for a YZ250 now, because I love that ring-ding.  Anyhow, if anyone in the Seattle area wants to buy an 18" Pirelli MT43 Trials tire/HD tube off me, I haven't sent it back, and it's supposed to be tits.

I had an MX race yesterday. First moto I was in third for four laps, then got past into second. Second moto I stalled at the gate, and started in 5th about 15 seconds back, but made it up to 3rd on lap 4. I believe, by virtue of showing up to two out of three races, this puts me in the points lead.

MonkeyNutZ posted:Awesome video, what cam and encoding settings are you using to get that kind of quality? Youtube seems to butcher my 1080p/30mbps/60fps uploads these days, especially with the kind of fast moving detail you get from trail riding. So I'm using the GoPro Hero 3 (cheapest $200 one) at 720p 30fps to maximize the amount of video I can record. For editing I use Sony Vegas, and these are my custom export settings that seem to work well: code:Zool, where did you race? I went to the pacific raceways mx track yesterday to see the NW 2 stroke nationals, but not enough people showed up and it just turned into a practice day. Still fun to watch though, and I want to ride that track Last call on that Pirelli trials tire, if anyone wants it.

I was at Evergreen Motocross Park in Monroe. I've only ridden Pacific once, it was a good time but way more crowded for practice. They had been it split up into 6 groups, EMXP usually has 1-3 groups for practice depending on turnout, so you can get more seat time in there.

Does anyone in the PNW know of or have a foam pit I can learn to backflip one of my dirtbikes into? I'll be on deployment for a few months but when I get back I know I will want to do something reckless!PoopSok posted:So anyways, I ordered a new kickstarter/key, and once I get this bike running I'm selling it.

Alright Dirtbike bros, I need some consolation on my seemingly broken XR400. I've been avoiding working on it and I need to get it back on the road for my own sanity. I use it as a daily commuter and general hooligan bike, but it is, in fact, a dirt bike at heart. Here's the issue: rode it at the track, everything was perfect (though I believe it was the first time I'd ridden it hard in the rain). Brought it home and attempted to kick it over a couple weeks later. Kickstarter felt like there was very little compression. No stop on the TDC "detent", no massive amount of force required to get it over, nothing. Saddened, I checked the valves which were incredibly loose on the intakes and OK on the exhausts. I had adjusted the valves before and later realized they were too loose. Could a few hundred miles of loose valves cause them to tulip? After checking the valves, I decided to open the bike up and check timing. Timing seems okay (off by half a chainlink and I can't seem to get it "perfect"). See picture below:  CCT seems OK. My buddy has a HF lighted inspection camera and I am going to take the exhaust header off and poke it into the cylinder to see if I can find any catastrophic damage. Is there anything obvious I'm missing? I REALLY miss riding this bike. I like it way more than my "spare" FZR600R I've been riding in its wake.

I don't have much experience working with 4t top ends but timing being off by any amount doesn't work well. Valves going loose in a short period of time also seems totally wrong. If it was me I'd find a decent mechanic to spend an hour looking it over.

I misspoke last night, I set them a little too loose, they didn't become that way on their own but yeah after I take a few more looks I'll bring it in to a local shop.

Sounds like you need to do a leakdown test. Have you drained the oil? Anything that looks like the remains of a piston ring?

I've become bored with my local trails which is why I did the race last sunday - started in the sportsman line and trail rode it just for fun (reduce knee stress). In the same vain I'll be doing an enduro this sunday in Berwick, Maine. It's AMA restart format (no time keeping) so I'll sign up for my appropriate class and see what I can do. If I tweak my knee or something I'll just trail ride the rest of it.

Enduros are fun. It should be a series of sprint races with 10-30 minute breaks in between. Next time you sign up make sure to ride with somebody who knows what they're doing as far as timekeeping and the experience will be much better.

Looks like i did my last ride in a while yesterday, me and a friend was out on the local enduro-trail, and he went first, he crasched in a rocky drop-down and i hit his bike and did an awesome stoppie flat out in second gear. He was a bit bruised up but otherwise ok, i cracked two ribs (the same as last year), and tore the meniscus(sp?) in my right knee. Well, atleast i can catch up on some bf4 i guess, and sorry if my spelling is hosed, but i feel a bit drowsy because of the painkillers
