I can definitely see that happening. It's just not a race type setup. I'm more of an ADV rider so never really pin-it to win-it.

The thing I don't like is the amount of road vibration that gets transmitted up through the bike. That reason alone may push me to a racetech setup. It kills me on long rides.

Air down the tires and watch the wobble disappear... Overinflation can make the bike very scary handling. Coming from bigger bikes, I overinflated mine at first.

Set it down a couple PSI at the time until the wobble goes away. Different tires - different pressure.

Interesting option- i run 22psi front and rear but will try 20psi on the front to see if the wobble goes away- if that doesn't work then another cheap option would be to switch to a super moto front fender....don't want to go too far under 20psi as i want to avoid any pinch flats when off road. Changing to a supermoto front fender made a HUGE difference on my old DR650 ( much better road riding). The crf250l front fender doesn't look floppy like the dr650 but certainly a cheap mod....probably go with a black colored one...

I run 15-16 psi in the rear and 16 psi up front no wobble at all, same with my new tires.

Never had any wobble, either with the original rear, or the replacement D606. The front still has some wear left before replacement, and I'm at a little over 8K. I do check with a bicycle pump that has the gauge built in if it's been sitting. Most of the time, I just put both hands around the tire, with my fingers clutching the rim, and push with my thumbs to see how it seems. When these tires are toast, I'm going with MT43 front 1st, since that one will need it before the rear, but probably get both at the same time. I always like having a tire on hand before I actually need it.

Wobble problem folks, maybe ride with someone, and have them watch to see what it looks like?

More fn' snow tomorrow.....

Are you running rim locks at those pressures or are they not needed?

Well I'll be dipped in dogshit! I just dropped my pressures to 19 psi front and rear and no more wobble! When I am on on gravel/ muddy back roads i take 'em down to 17psi and have not needed rimlocks yet. But I am not going hard on the braking which is what usually causes the tire to spin and rip out the valve. Guess I don't need to swap out the tires after all...

I don't run them but we have nothing but deep sand here, so spinning and catching rocky mountainous terrain won't be happening for me, not that its impossible to spin a tire but i haven't had an issue yet.

AirBox mod: Fabricated new snorkel

At first I was resistant to modifying the air filter and airbox -- but I finally decided it's worth a shot. I did not want to drill the airbox cover though, and I also didn't want holes level with the airbox lid that would allow water to migrate into. So here's what I did:

I fabricated a brand new snorkel to replace the stock one. My new snorkel is at least 60% larger I.D. than stock (based on a quick measure of the oval stock snorkel). It actually looks almost twice the volume. I used a 2" I.D. flexible rubber elbow (available in the plumbing department). The photos don't clearly show it, but because of the shape of the airbox, I cut the opening freehand (fine tooth keyhole saw) in a slightly bent elongated curve, then pressed the rubber elbow to conform to the available space.

If after a few weeks I am satisfied with this, I'll silicone seal where it inserts. Doing it this way, also gives me the option to fabricate another version that extends into the airbox as far as the stock snorkel did, to reduce the induction noise -- and if you listen to some -- to improve low-end torque. At the moment, I quite like the throatier growl that I get from this snorkel length, and the performance seems markedly improved.

So now my question is: how much should I enrich the EJK settings? Before this mod, my settings were for a stock bike as suggested by EJK: 1.5,1.5,2.5 (cruise, acceleration, WOT). After the mod, I enriched the settings to 2,2,3, to make use of the increased air available. The cutoff/engage settings are unchanged from the original EJK settings for this bike. I haven't inspected the spark plug yet. I want to ride it for a week or so first. A quick sniff and poke at the tailpipe though, tells me it may be running a tad rich, but it's cold outside, and that can enrich it more than normal also.

Opinions... thoughts... ?

PS: I also removed the backfire screen from the filter, I have 13/42 sprockets and stock exhaust.

Thanks,
John
