Pinned Look what the postman brought today !

@ShaneP is correct.

Ohm's law. If you double the resistance with the same amperage, the voltage must be halved. No way around it.

Think back to your simple circuit of a power supply/battery, fuse, switch, and globe (load) that they teach (I did it again just this week, and did it before during my Cert 2). If you add another globe in series, they both run dimmer. Exactly the same thing.

Double the resistance, the same amperage, half the voltage.

Parallel circuits multiply the amperage and half the resistance.

Was discussing this problem with my teacher at TAFE today... the gist of it was to wire them up in parallel and see what happens, or 'suck it and see' - my main concerns are blowing the transistors in the TCI, blowing fuses or melting the wiring.

With all that said, my ZXR has been happily running along since I did the original installation and it has been running fine, so clearly there is enough juice for a decent spark.

Wiring them in parallel will require resistors.

 

This confused me. Ohm's law is Voltage = Current x Resistance (V=IR, I is current) but it slightly misleading because voltage is set/supplied "force", and current is the resultant flow through the resistance. When working out total resistance, in series (a single line of flow through each resistor one after the other) the resistance is added - R total = R1 +R2 +... In parallel (think of it as turning on multiple taps, one pressure source, more opportunities for water to escape, greater amount of water escaping) the total is found by adding the inverse of the resistances: R total= 1/(R1) + 1/(R2) +....

Once you have your total resistance, then you go back to ohm's law to work out the current. Of course, you could connect your multimeter once it's wired in to confirm it.

One thing to note: if they're in series, then both coils stop working if one is faulty, but if they're in parallel, one can stop working and the other will keep working normally.

 

I finally got my shipment from Japan.. 3 days for EMS to get it from Japan to Sydney and into the Australia Post system.. and then nearly 10 days to get to me.. still... it arrived with my SRX6 lower bridge & stem, plus an SRX6 front axle.
I also picked up a headlight mount (it will need a little modification to fit) and a good set of mirrors.. plus another kilo or 2 of SRX mixed nuts and bolts..

Side by side with the FZR item









And then my tyres arrived.. one yesterday and the other today

 

Haha, it actually cleared Customs etc in the 3 days ex Japan. I use Zenmarket and they had all the correct paperwork showing the GST etc.
it was purely Australia Post that took 8 days to get it to me.

I would love it if it was as simple as swapping stems.
The FZR stem is welded in and the section above the top bearing is different so it will be a custom machined stem or, just looking at it, we may be able to get away with an insert into the top bearing recess which will accommodate the standard upper bearing from the SRX6. The bearings are 15mm deep where the FZR are 13mm. All other sizes are the same.
I will talk to my machinist and see what he thinks.

My little package of Titanium disc rotor bolts arrived today



And while they havent arrived yet I ordered these this morning.. in anticipation of getting my rims finished soonish

 

When I had a good look at the tyres I bought I realised that I had clicked on a rear tyre instead of a front tyre and then looking up the specs the tread pattern is different front to rear. So I called the eBay seller (a Yamaha Dealer) and he arranged a new front tyre to come in and I shot over this morning to collect it.. even though it should have been $10 more he just swapped it over with no charge.. so a big shout out to Trooper Lu's Garage at Moorebank (Liverpool) and specifically to Marcus in spare parts.. Way more helpful than my local Yamaha Dealer..
While there I had a look at the new R6, while I am not a big fan of the newer bikes.. this think looked really good..
Anyway.. Blatant plug for Trooper Lu's is now over

 

I use Trooper Lu's website for parts catalogue. It's one if 3 online parts catalogue websites that are continually open, along with this forum, daily Mass readings, TMR, PPSR, and 5-10 other sites... But a very bike bias!

 

Took 2 weeks from order, not that I had time to work on the bike. Mc19. Paid the $30 for Australian seller to be quicker, too.

 

I thought BOC must have dropped the rental, too, everyone else seemed to. Even lose the bunnings bottles, it is cheaper than a year's rent!
