Thanks Sparky! smiley

I started my new JU-02 bike engine today!!!!! cheers



It runs perfect with very cold temperatures, so plenty of room for more power later by narrowing down the jet pipe. cool

Cheers!

Thank you Pete!

I am very glad and a bit surprised that it all went so well without fuel leaks or bad combustion, but I guess I made most of the mistakes while building JU-01 and learned from them. Any major design flaws will show when I take her higher up in revs. This was only a high idle, it is designed to run at twice the boost pressure, 4 bar.  smiley

Gorgeous! Just one thing irritates me (even though I think, I already know the answer): You don't seem to wear hearing protection in the video? Is it that much quieter on the induction side or were you just too excited to get going? (No offense, just wondering... I only know turbine from planes and they are much larger obviously.)

Cheers,

It is hard to see but I am using foam plugs, I wouldnt want to be near a running turbine without ear protection since the compressor whine is painful.

Last night I finally decided to build a side stand for the bike, it was getting tiresome to be without one since my friends had to carry the paddock stand around all day long at the races so I could get off the bike before and after a run.



As you can see it is foldable and secures properly in both positions, I wouldn´t want it to drop down during a run...



This morning I put a couple of coats of paint on it, so now it melt in with the rest of the bike pretty well.



As you could see on the previous picture I took the bike out to get some sunshine after almost a whole year in the workshop, the side stand will work fine despite the lack of a wide plate at the end since I will only have the bike standing in the shade below the race tent on concrete or asphalt. No wet lawns for it to sink into. Smiley

I modified the bike towing cart today so I can use my girls quad to tow the bike, Agnes tested it around the lawn and it passed the quality control. Smiley

Judging from the style she rides the quad she might very well be. grin

I started the bike today to see if everything is ok for One Mile, I didn´t have a chance to test the water injection since the bike almost took off at high idle despite a locked rear brake. Smiley

Anders, what was the little flame at the turbine at the end when you shut down ?

I love the way your family walks by your bike as though its normal to have a turbine monster in the garden,

You mean the little blink just when I shut the engine off? Probably just some kero or oil catching fire, nothing to worry about.

They are pretty used to practically everything that makes noise and burns by now, so the future suitors will have a hard time trying to impress my daughters. Smiley

Anders - I hope you do well at the mile race.
Question: Are those billowing white clouds vaporized kerosene or whatever fuel you use? Is that flammable?

Thanks Don!

Yup, it is kero that didn´t ignite during the adjustment of idle fuel flow. We get those clouds all the time with the afterburning jets and they don´t seem to hold enough fuel to be ignitable.

Once everything is tuned in the bike starts effortlessly without the flame and smoke show. Smiley
