Why is the 426 hard to start after you stall it.

18 posts in this topic

My 426 runs great, starts right up cold. Always starts first kick when riding if I use the kill switch when I stop, but if I stall the bike it can be a real bear sometimes to get started again. I know its notorious for this just wondering what the mechanics behind this would be, in other words why is it harder to start after stalling as opposed to using the kill switch???

Because it is missing 24cc :banghead:

Actually it was designed at the earliest stages of 4-Stroke development

They have figured the starting problem those early first bikes. Adding auto decompression on the cam lobes was a huge help

The actual reason is that it's more prone to flooding/fouling the plug when stalled or tipped over.

I was thinking it had something to do with flooding, but was just curious.

Thanks

it should not be hard to start. my partner ride s 426 and it fires hot or cold. make sure your hot start is working properly.

hot start is good, it was replaced about a year ago. And it fires hot fine but only if it is shut down with the kill switch

stock jetting. Fuel screw 1 3/4 turns.

First step is to get a JD jet kit and wire the accelerator pump. The stock jetting is horrible in the 426.... or at least it was in mine.

Where is a good place to order a JD jet kit? I just started riding an 01 426 and really like it. But it really bogs down when climbing at higher altitudes. I think the hard starting after stalling or falling is mainly flooding. I pull the decomp. lever and give it several kicks to clear out the cylinder if it doesn't start right away. Then try and start it. Works some times.

Lean out the pilot a little bit (with the fuel screw)...has huge effect on restarting hot (at least on my bike it does)

All four strokes are hard or harder to start after a stall, not just the 426.

I can cart wheel mine, let it lay upside down for 5 minutes, pull the hot start and it will start on the 3rd kick. When everything is working properly (jetting) they start up quickly no matter what you do.

The TT store use to carry them or you can order straight from JD.

But when you don't cartwheel it, it still starts better than that, doesn't it?

Stop dodging. Does it or does it not normally start better if it hasn't been flopped on the ground?

lol... Actually with the Rekluse Pro, its very hard to stall it. (but possible under the right conditions)

It makes no difference if its been crashed or not. 1-3 kicks and its starts. If its been crashed, I pull the hot start... if its cold i pull the choke.... if its not flooded or cold, I just kick it. This applies to the 290 too.

:banghead:
