But what's it weigh when the batteries are full?

Electricity does have mass, so you could measure it with good enough scales haha

Need to check my spreadsheet but I'm up around 35kg off.

It just gets confusing as many things like exhaust are so many iterations on from factory. Need to weigh the whole bike.

I can say it's massively noticable when riding. Compared to a factory one it's like a whole new bike.

I also cut down my levers and welded new balls on the ends to make them look legit. Mostly just because they looked cooler 

About 2% of the brake removal crowd does it for the right reasons. Very common for Americans to take off one front caliper and disc, and the rear caliper and disc, just to get the look they want. It's seriously stupid.

Replaced the steel engine mount bush things with aluminium. Shitty job to do for bugger all weight saved.. had to cut a socket into a tool to remove the factory pieces.

150g removed 

Removed the heavy steel bracket, lower aero tray and voltage regulator mount thing, then relocated the voltage thing up into the tail. 

622g saved

I deleted the oil cooler and blocked off the outlets. These bikes do not need the oil cooler even when turbocharged and making 600+HP, so although it's a strange thing to remove- the benefits are numerous.

2055g saved and it's now a whole lot easier to change the oil filter as the oil cooler isn't blocking access 

I spend ages thinking about where else I could save some weight and the best way to make this. I wouldn't do it this way again, but it's good enough that there is no reason to change it now.

The factory fuel tank mount incorporates a hinge and is quite heavy steel 

The hinge is cool because it means that you only have to undo two seat bolts and two tank bolts to lift the tank up (to access the airbox)

My new tank mount does not hinge, so rather than four bolts you now have to undo 6..not really a big deal.

This saved ****TBC****

I have done a fair few km with this bracket now, so I am pretty happy with it. I was initially a little concerned about loads (you brace yourself against the tank sometimes) but it's rigid and STRONG.

I had drilled holes in my factory exhaust mounts to try cut some weight out. These were cast aluminium and 680g each.

Holes were cool but when I changed to a single sided exhaust there was another opportunity to drop weight. I used filleting wax to smooth out the cast part and fill in the holes id made, then poured a mold in silicone, then made my own exhaust mount using a mixture of carbon and kevlar. I oriented the strands appropriately so that it was the strongest possible (well, as strong as is possible within my garage) component, with strands wrapping around the full part and around the mounting holes etc. it is STRONG..

The single component weighs 129g, a saving of 551g...but as the left side is no longer needed at all, there is a total saving of 1234g

Really didn't like the look of it so painted black in the end.

Made a carbon fiber heel guard too.

I bought two old mufflers off trademe cheap. One was full titanium but buggered from a fall (was worse irl than it looked in the photos)

The second one is a super cool old carbon fiber muffler.

Unfortunately the carbon one had a hole from an impact, was too long and was sized to suit a little motor.

I patched the hole with carbon fiber on the inside, cut both ends of the carbon body off to shorten the whole thing (the ends were all messed up) and then put the bigger guts from the titanium muffler into the carbon one. It's on my list to tidy up one day but for now it looks alright and works well.

Since I replaced two heavy (but still lighter than OEM) mufflers with one carbon muffler the weight saving overall is HUGE. gets confusing without checking spreadsheet but approximately 15,000 saved vs factory mufflers ****to edit later.****

Bought a very cheap set of yoshimura stainless extractors. Unfortunately they were missing the head flange things so I cut the pieces off the factory headers, re sized the tubes in the press by pushing through a torpedo so that they slid into the extractors slip joints nicely. 

I was quite proud of how well these cleaned up- I soaked the stainless in a bath of Citric acid for a few days and they went from shit to nearly new.

3900g saved from extractors alone.

Removed the clutch covers external dampener weight thing to save 228g

It's covered by the fairing anyway so it's a waste of space 

Took out the radiator fans, drilled out the welds and removed the steel guarding to save 220g

Hah, haven't been here for ages.

*Numbers below may change once I look at spreadsheet but let's hope I'm reading my phone notes right.

Removed the smog stuff and fitted some nice cover plates to save 449g

Actually yeah be better to get some paper bags of concrete, empty the concrete out the back and then fill with beanbag beans lol

Lumpy fibreglass cover so it looks.like you poured wet concrete in the frunk

How big is your trunk Alex, if its not too huge ill look at doing one in carbon fibre 

I had to read that whole FB chat and put my 2c in

The company I now work for is producing a great product with zero cons for the consumer. 

The Facebook page is full of fuckin Karen's putting their 2c in about how it's shit. Every single post I need to bite my tongue haha

Its been a total pleasure being present for parts of this build.

Interesting. The cam blanks I was told have a very low reject rate. Maybe a specialist foundry.

most definitely a specialist foundry if they are doing 90% of the worlds blanks. Wouldn't be a small operation.

Its D for delightful.

never, you get a 'get out of jail free' card when driving a tired old leaf that needs DC charging  

and DC charging out and about has pricing set to be on par with driving a petrol car. Why? because they can i guess? but its 3x the price of charging at home for the convenience of using their $120,000+ charger

Exactly right now that there is tax on EV's, you may as well drive a petrol car.

Pretty sure i have been over this but dads CX5 and my BYD cost the same to run once the tax comes in (if you charge publically)

I still think the driving experience is enough to make EV's a great option though. Its only a BYD but i find it a really nice place to spend time.

The lease cost still has to cover the depreciation, so leasing isn't a free lunch to avoid the loss.. 

yeah I have battled to the death on this. Lease companies are making money at your expense- Definitely not a free lunch, but I can understand why businesses take that route.

Sorry just saw this. Id say unlikely to even be on canbus let alone sent to obd2. (Which is usually cut down to a standard set of things)

Its possibly info on canbus though, but thats highly specific car to car.

You can use a can bus sniffer to see if any of the bits or bytes change value when you hit the brake or indicator though.

 

 

Old post, but I'd like to say- It can be amazing which things ARE controlled by canbus these days. It would not at all surprise me if brakes and tail lamps were more often than not canbus these days.

Even tail lights on new motorcycles can be canbus. 

the BYD's horn has an annoying delay which im sure is because its controlled via canbus. Its definitely not hard wired like traditional.

Hello….. I resemble this remark (not just mathematically some would claim )

But even I can (mostly) follow Professor Dave’s tutorial 

I have done some pretty cool things with arduino but seem to forget things just as fast as i can learn them.

I have no idea what he is talking about most of the time but the moving lights are pretty.

What about all these ones?

 

We are only provided with a chargenet fob- supposedly the largest most widely available provider. I'd love to have an account for every different charge supplier but that's not how things work.

Same as with fuel cards - employers will provide one fuel card to suit one or two stations, not three or four different cards to suit every different fuel provider.

I get your point though- it's a problem with our process not the number of chargers, perhaps.

For a lawn tractor I was just going to mount a DC motor vertically and have that run the crankshaft pulley in place of an engine. I live off grid so the plan was to use my a house battery bank in the mower/tractor and charge it off solar. Hence a 48v motor. 

This couple did something a lot more gucci with an F150 lightning and their house. They drive to town to top it up so they don't have to run a generator. My winter generator is 115yo Lister so I doubt Ill change that as I enjoy hearing it clank away. 

keeping the belts and transmission would be dumb. they are the worst part of every mower.

I saw leaf swap it.
