Flogged her pretty good this weekend. All day Saturday, leading a group all over the "good" roads in NE Nebraska. Then I cleaned!

I enjoyed taking my 400E up Taylor Pass over the weekend. It's the most challenging road I've taken my bike on.

They call this a trail in parts Utah.

Ok, re-jetted my S with a stage 1 Dynojet kit, 134 main, like it said, 4th clip up, fuel screw 3 1/2 turns like it said.

It got rid of the WOT bog, but I get a bit of pinging when I crack it in the cruising to mid rpm range, higher RPM's it's fine....

Still too lean I'm guessing.. Where should I start, raising the needle, or change to the 136 jet?

I'm thinking raising the needle position first, reading that it usually controls between 1/4 to 2/3 throttle, also given that it's easier to get to, rather than pulling the carb for a jet change....Good idea, or go straight to the main jet???

I had the same issue during testing after reassembling the cylinder and head, but it turned out to be the chain slapping when getting on it from mid/low rpm on the street. I thought my engine was going to explode at first.

Check your chain tension first so you're not amplifying it. Cruise around as long as you can at the suspect rpm then shut down and allow the engine to cool before pulling the plug and checking if the mixture is too lean. I'm not sure the stock engine has high enough compression to ping on a hot lean mixture or not.

Aside from that noise, how is the idle and throttle response below WOT?

On the last... The lighter spring with the DJ kit allows the slide to open more increasing pressure (reducing suck) at the needle jet causing a momentary (a second or three) lean mix when the throttle is "cracked". Slide response is limited by the need to accelerate the fuel in changing conditions. The OEM set up is a fairly fine balance of spring pressure and slide port dimensions to produce a slight delay to the slide in order to provide a momentary lower pressure (more suck) to accelerate the fuel through the needle circuit before the slide stabilises... the function is throttle mixture enrichment for CV carbs in lieu of an accelerator pump... The DJ kit messes with that balance requiring overall wetter mixtures to compensate or other measures such as slide port adjustment to correct. It is just easier not too buy DJ kits when other better designed kits are available.

One thing at a time. I'd start with the needle if WOT above 7000rpm is okay.
Scuse my brain fart but WOT ??

I think it's the same as WFO!

I'm kind of not surprised my bike is still running lean, being at sea level.

If by cracking you mean fully opening the throttle it would be the main jet as the needle is tapered out of the metering area. If you mean only another quarter throttle then it would be the needle, but the needle position would best be adjusted based on steady cruising at that throttle opening rather than momentary responses. Also realize that a sudden change in throttle is variable depending not on the twist of the throttle but the overall vacuum moving the slide which in turn adjusts the positioning of the needle. In other words there is no direct relation between the throttle position and the needle position.

Yea I searched for a while and didn't find any in the rates I was looking for used. I'm guessing not many people upgrade the springs and then sell them off later...

$180 new springs (Shock Spring 5.7 & Fork Springs 0.48)

What kind of bulb does a drz400E use? The single filament 55w one.
Thanks
