Continuing with the wiring, lots of thinking required to avoid having to do everything twice... I routed the oil tank vent to a place further back so the smoke won´t catch fire from the jet exhaust. Half of the dashboard wired up. Something I really need to do before the first test drive is to find a small enough CO2 extinguisher that fits the bike, I would never forgive myself if a leak is sprung and the bike burns to the ground while I am searching for something to put the fire out with. There are 2kg aluminum bottles in store but they are a bit bulky so I am considering making a custom handle for a Soda Streamer bottle, they hold 0.5kg CO2 and are slim enough to fit between the steering head and the seat. I can even fit two if I want to. Cheers! /Anders

And everything will of course be bundled together in fire proof cable covers later in case you wonder, so no hanging wires all over the bike.

Hi Anders
Good thinking about the extinguisher ,............. I wished I'd had one after the first road test of the TV84 bike when the gearbox filled with frothy oil and the scavenge pump couldn't cope , the gearbox breather spewed oil out and it caught fire on the freepower scroll , I had to lie the bike on its side until the fire burnt itself out, it wasn't a pleasant experience seeing years of work on fire, especially with a near full fuel tank onboard :-(
Gearbox breather was soon plumbed back to the oiltank .
Take along a full sized extinguisher as well , it'll be good insurance during spoolups and post run shutdowns when lotsa things are still "glowing" :-)
Whens the first ride planned for ??
Cheers John

Hi John, Ouch, that didn´t sound very pleasant at all. It is one of those things where you just have to get it fixed since he thought have crossed your mind, I could never live with myself knowing that I did consider it but thought "nahh, too much work" and later the darn thing catch fire. I don´t plan anything, with the work around the house and vacation coming up it can be everything between a month and three before it is ready for a road test. As long as I beat the snow to it I am satisfied. Cheers! /Anders

Go with a Fyre's Out liquid extinguisher . They will put out more fire than a co2. Same sizes available and they use a wetter water method, similar to foam.

Thanks for the hint! I can´t seem to find any Fyre´s Out while Googling for it, mind sending me a link? One named Stop-Fyre looks really good but I need to be able to refill it somewhere around where I live. Posting the emptied extinguisher to USA for a refill is not a practial option... www.serenityvalleygear.com/product-p/msf.htmI think a dry agent is preferable if I can choose, squirting a water based fluid on a glowing turbine wheel is not very good... Cheers! /Anders

Remember all sanctioning bodies require a liquid unit... The surface tension is extremely low and will penetrate the gasoline.
Much safer..

Agree with Ernie, go for a water based unit on the bike. You may want a dry powder as a extra in the pits, but the main reason they want water based is not so much to put the fire out, but to protect people.
A few years ago at Bonneville (I believe) someone had a engine fire in a front engine streamliner. They fired both their dry powder fire extinguishers that worked perfectly. The only problem was the car was still rolling and powder just blew out the back and the driver was badly burnt. A similar accident with a foam/wet system wets the driver and no burns.

I don´t think the LSR rules state anything about fire extinguishers on open motorcycles, so I should be free to choose whatever type I fancy.
The thing is, if I have some residue oil burning off in the jet exhaust and I fire a liquid extinguisher in there I will fill the engine in seconds causing all sorts of damage in the glowing hot engine internals. A CO2/halon/inergen unit won´t leave a trace and unlike a streamliner I won´t be helplessly strapped down inside the chassis but standing beside it trying to put the fire out.

Found a nice electric box in a scrap container at work this week and made a new lid for it. A perfect fit for the ignition system! I will route 12V from the bike to the ignition box through one cable pair and use another pair to get the high voltage signal back to the bike. Cheers! /Anders

A CO2/halon/inergen unit won´t leave a trace and unlike a streamliner I won´t be helplessly strapped down inside the chassis but standing beside it trying to put the fire out. Fit both types, a dry one for those pits/low speed Oh Bugger! occasions and a big overkill wet backup for OH SHIT!!! situations if things get really nasty. If you run water only injection, you could dual purpose that as a last backup, a bigger tank than you need, an extra solenoid valve and some nozzles. You won't want your legs being flame grilled while panic braking from 200mph. Don't assume a fire will only come out the exhaust, there's lots of places that could shoot flames if something breaks. CO2 etc into the air box would cool things rapidly as well as suffocating flames, but you'll need a lot at full revs, several kg per second. While on the subject, nomex over your leathers? Pay attention to Murphy's law: If it can break, it probably will. Add in some high speeds and 'overkill' safety measures sometimes aren't so overkill.

When one of the karts hard to be put out at santa pod, they used powder, which stuck to the every hot bit it landed on, turbine wheel every thing.......

I´ve found a 400ml foam extinguisher locally, spray can sized so it can be placed anywhere on the bike. I am doing lots of progress on the wiring but it is impossible to take a picture that represents the work done... Cheers! /Anders

Houston, we have oil pressure! After four more hours of wiring I had everything set up for some pump testing, the oil pumps ran like they should so I filled her up with some oil and was rewarded with a rock solid 5kg oil pressure with not a single drop of oil leaking through the drain hose on the engine cover! I spun her up with the scuba tank and everything ran smoothly with no rubs or sign of tight tolerances, still not a sign of oil leaks after a minute of full oil pressure so I was very pleased. The throttle potentiometer didn´t work though so I will have to do some fault finding this weekend, no big deal. Cheers! /Anders

Hi Anders
She's alive, and pumping "blood" through the system, not long till she can have a drink of kero ;-)
