    DR350 carb settings/adjustment

    The pilot screw should be tuned with the bike running, after warmed up. Turn in/out half a turn at a time, until the best possible idle is achieved. Turning it to get the best starting scenario will make starting easier, but will definitely be mismatched to running conditions.

    96 DR350SE front end dive

    Was the previous owner a petite lad? Because he might've tuned the suspension to match his weight. Not that standard dr suspension is anything to write home about, mind you.

    DR350 Bogs and Dies as soon as i hit throttle

    I think it's more to do with the amount of ethanol in todays gasoline than the nitrile. I've had "good" o-rings swell up in cheap gas and "bad" o-rings be fine with premium-lower ethanol gas.

    DR350se carb question

    If it runs well with that small an opening, then I'd say it's running much too lean, but then again, with a stock bike it really shouldn't be that bad. Have you checked for air leaks around the carb?

    Dr 650 sp444a won't cold start

    How much time was it sitting? You probably have some gunk in the carb and/or bad gas. I'd clean the carb and pour some fresh gasoline in the tank. When my dr350 is being too stubborn about starting, like after leaving it for two or three weeks in the middle of winter, I try to jump starting it (decompression lever in, start in neutral and jump it in second), and even if it just sputters a bit, it's usually enough to get it going the regular way.

    DR350se carb question

    When you mention 2 turns out, do you mean two whole turns? Because that's a bit lean for an open airbox and clean filter for fall, let alone the coming winter. What's your needle position?

    DR350SE transplant questions

    Mine absolutely hates backpressure. When I put the db killer in the can I completely loose the ability to get the wheel up in 3rd and almost in 2nd.
  8. So far most of my injuries have been minor-ish. I over extended my right elbow last year, that hurt like hell for a couple of weeks. It still isn't quite right, but doesn't hut anymore. It's just more prone to be overextended. Around september 2017 I twisted an ankle (riding with steel toe work boots at the time) that still flares up if I go out a run. Apparently I have some calcifications on the soft tissues, thus it's pretty much jacked for life. A dog ran in front of my while commuting, and down i went. Scrapped a knee pretty deep and took an engine case to the left ankle (was wearing regular shoes). Both are fine now, but I try to at least wear over the ankle work boots with side protection on the street. Took a nasty tumble at around 40kph into a rut and took the weight of the bike on my right thigh. That was the worst bruise so far. I couldn't walk properly for about a week. Otherwise, just a few bumps and bruises. I try to ride trails with as much protection as I can, because shit will happen and when shit happens it's better to be safe than sorry. I will always wear boots, knee protection and kidney belt under the upper body armor (got a dodgy back).

    '98 DR350SE won't start, help :)

    Kick it about ten or fifteen times with the ignition off. If the plug isn't wet, then your pilot is clogged. Usually my ritual is something along these lines: If parked for over a week -kick it ten times as fast as I can with the decompression lever pulled in at wot -full choke, go to tdc and give it a big one >if it barks, then choke in, kick it ten times and do it again. Usually works first or second time. If parked for a day or so: -kick it over five times at wot with the decompression lever pulled in -half or full choke, go to tdc and kick it over >if it barks, then repeat until it starts. Have you tried bump starting to see if you can get it to at least bark? Sometimes the kill switch can get iffy if wet press it in and out a few times and try again.

    DR650 engine in DR350 frame?

    The gs500 as a bike is a bit of a dog, but from what I've been able to research, the engines themselves should of a similar weight, with the added bonus of around 10 - 15bhp. But then you'd need to add some weight back with the twin exhaust, dual carbs, and oil cooler. From what I recall, the gs engine is also wider, which would be a bit of a problem. Honestly, if I had a broken dr350 engine and a broken g500 motorcycle I'd give it a shot.

    DR250S still running too rich after carb rebuild...

    I never trust checking it with a hose. I'm a bit anal like that. But I'm still pretty sure that this a something or another in the carb type of problem. I'd disassemble everything again, clean everything meticulously - for instance, the brass plug where the seat seals is usually filled with junk that carb cleaner won't knock off (last time I had to polish it out with some abrasive and a q-tip on a drill).

    DR250S still running too rich after carb rebuild...

    Well, that narrows things down a bit more. Have you checked the float height? Sometimes the o-ring were the float attaches to the carb body swells up and causes havoc.

    DR 350se Idle issues

    Sounds like you're running really lean. Does backing the fuel screw make it run better?

    1990 DR350S

    Honestly, I'd steer clear of expensive carb "performance" kits. Open the airbox, clean out your carb, install a stepped needle and jet it to what jessie from kientech mentions and slap on a freer flowing muffler. I bout my dr with this combo and the throttle is pretty damn snappy for a cv. If I jerk the throttle more than halfway at 2500-3000rpm in second the wheel will come right up. Third requires a bit of a thug, but still doable. With the 13-52 dirt gearing it gets a bit silly.

    That part were you mentioned drilling out the pilot jet is the most suspicious to me. Pilot jets are so small, that even drilling them out with the correct size bit will most times result in a larger than normal hole. All it takes is a sleight wobble in the bit, and there you go, a couple of 0.0x mm's will do a hell of a lot.
