Jet chart - The effect at different throttle openings

[per_w_aberg]

That's a big step for a jet but a small step for me :) I made a qualified guess. It hardly revved up on ~20% throttle so I knew I was way off. The way I see it its better to start with a big brush. Jets are cheap and I sort of wanted to start on the far end. Its a bit like tuning the suspension on a enduro bike. If you go 1 click you have to darn clever to notice any change jumping around in the woods. Starting big and narrow it down just suits me I guess. I actually got some 90's to!

I have the micro drill bits here to get the pilot up to a 70.  Haven't done it yet though.  USPS lost the package and it was a mess, but that's another story.

Thanks for the tuning sequence POD. Nice logical way of tweaking the jets.

Time to put Bessie back on the road again after the winter layoff. I am determined to beat the bog this season, then maybe start to tidy her up a bit. Not too much mind!

Per, have you put pods on the BD34's? Any close-up photographs of your set-up?

Thanks

It has always been my opinion that if your bike is stock, then changing from the factory jetting is probably not necessary.
I'd go for a good sync first, then cleanliness, and if you still have a bog then look at your accelerator pump.

Semi synth oil and iridium plugs also helps incredibly for a smooth running and happy bike.
