Weight loss, not me fool! The bike

[ELIMINATOR]

Years ago the silencer came off and was replaced with a stubby.

Several oil changes ago, I didn't bother refitting the sump guard.

I was 48 when I bought the GS, 2 decades have passed. I can no longer casually throw my 28 / 29" inside leg over the seat, with bike on side stand ,but put the bike on the main stand. I dismount standing on the left peg.
Even then, I scrape the pillion seat with my boot, so I removed this.

Bike had the MOT last week, I was told that it's illegal to ride without a pillion seat while keeping the rear foot pegs, so I removed them.

This week I'll be removing the servo assisted ABS parts.

Out of curiosity I weighed the removed parts, not including the servo.

On the bathroom scales, comes to about 10KG. Although over the years, I've probably gained the same
Shame I cant dump weight so easily, although..... I did have the shits the other day, probably came close then. Hmm, perhaps not.

Anyone know what the servo ABS unit ways?

Not sure on the ABS unit weight, but it is quite a heavy large unit. Simple, reliable system with it gone.
I don’t think the odd bout of the shits will make much difference.

You will trim around 5kg by removing the iABS unit and pipe work to the front splitter.

Don’t forget to retain the black iABS control module, and cut a piece of alloy plate to cap it off

The tester is incorrect, it is a fail to have a pillion seat without pegs.
Section 6.2.12 of the tester’s guide simply refers to a footrest missing or insecure.

He has misinterpreted the regulations.

Few years back someone on here gave me the prog. for a 3d printed plastic lid. Took it to work and they printed it for me, never realised that I's actually get around to using it.

About 15 Kg lost then, not an insubstantial amount, and the 5Kg of the servo is high up on the bike.

You could try drilling holes in everything......


(go on, go on, go on.... and video the test ride... )

That’s an early ABS modulator… Eliminators bike has the later servo/abs modulator .,

Thought it looked different to mine.

I don't think the metal brake pipes would have lasted much longer, showing signs of rust when I extracted them, notably where the spiral wound protective sheathing went on the 90 degree bends.

On the basis that my GS weighs 238KG and has 85BHP, this gives it a power to weight ration of 357 BHP per ton.
Losing 15 KG from the bike, increases this to 381 BHP. 24BHP gain Although due to my weight increasing over the last 2 decades, I'm probably still at 357bhp, but, it would be even less without parts removal.

I found this amusing in the context of go faster silencers costing hundreds of pounds, and claiming (for instance 5bhp gain.)

Being cynical I wonder if this is due to the possible weight loss, more than a carefully calculated design.

Moral of the story, if you want better BHP per ton, lay off the burger and chips... and beer... crisps... chocolate...

Unfortunately add some fat old bloke onto the bike and it becomes 263bhp

But you haven't factored in that everything feels so much faster these days...
