K75gsa RTW Special
« on: June 29, 2014, 02:13:58 AM »
Hi there, I've took the plunge and finally started my project, I'm building a very unique 'one off' K75 GS Adventure bike. Yes, many have been done before me but I'm putting my own twist on things with some very bespoke features. Very pleased to find this forum I have a feeling I will be tapping into the latent wealth of knowledge stored within....!!!!!!

All the best MEZ

Did I fab this...???? I wish...!! It's nowhere near finished at this stage, there is an auxiliary fuel pod that combines with this tank to give it a mind warping range too, photo's will follow just battling with work demands at mo..!!! Cheers anyway..!

Stainless steel fuel rail for peace of mind reliability..!! The old steel one became porous after welding......

how do the injectors mount to the rail--will the sharp edge of your spigots cut the orings on insertion?

Looks like a cool project.

If I was putting together a RTW bike I think I'd want it as stock as possible so that it would be easy to swap parts in faraway places.

Hi Kenny, there are no sharp edges, it was a perfect fitment, had the injector bellmouths machined by an 'old hand'...!!! I'm chuffed to bits with the outcome, bespoke engineering is only beneficial when it's done correctly especially when your replicating OE bits from companies like BMW, were getting there slowly...!!!

Hello Tim, I really wouldn't like to go RTW on a stock K75, I chose the 'k' engine for obvious reasons but as for the rest of the bike a big 'No No', the complexities that come with a special are many but if something is worth doing then just simply do it right, everything on the bike is done with OTT engineering in mind, the concept of the build has changed a little but the end result will be something very unique and bespoke which is what i'm into, once you've had your mind warped by a home made Turbo bike then there really isn't really any other options available to you...!!!

'Pod Air Filter'...??? I'm new to the 75 so is this an aftermarket air filter..??
I am going to run a K&N gauze filter and have created a fully sealed ram air system scooped directly from the screen down through a large bore pipe through the tank connecting to the airbox again via a pressure fit arrangement. When it rains we have fitted a swivel arrangement that blocks off the air scoop and draws from behind the screen......

All a tad 'MadMax' but heyho...!!!

Yeah,I recognise mad alright.
There are easy k&n conversions but your ahead of that...just a concern for heat accumulating in the fuel on very hot days."Space"down there would help with flushing that away.All good.

Interesting conversion, I would be interested to know how much it weighs when your finished. :dunno

I've thought about K75GS conversions but it seems like 1st gear is too high to be suitable for difficult off road situations like hopping over logs

I find it a bit hard to visualize a K75 log hopping. Although in the early days I had to follow a couple of G/S's in order to find my way home. A lot of on the peg riding a two rocky creek crossings and a lot of sweating, lucky not to drop it.

+1 on log hopping.  IMHO K75 off road riding is probably limited to unpaved mostly gravel fire and logging roads.  Beyond that, I suspect you are looking at a LOT of drops and damage per mile.  The bike is too heavy with wheel size and geometry terribly unsuited to rough terrain.  It might be possible to get one over land in a desert, but in the woods I've ridden in, you would spend almost all your time picking it up.

When i saw that bespoke aluminum tank i was very impressed with the welding and design abilities--but then all the bespoke steel bits started showing up front and rear.

Maybe if the bespoke steel tubing was made of bespoke aluminum it could reduce the extra weight.

Hi Kenny, you've not said anything remotely positive on this thread and you haven't attempted to answer any questions with worthy answers either, bit odd I find...!! You don't understand what overlanding is all about I feel. Aluminium is fragile in comparison and the gauge tube were using is obviously not as light as alloy but the 'out in the field' advantages of steel out weigh the weight issue. I don't wish to sound abrupt but have you ever built a special before..??

Yeah the fuel issue, we have fitted a cooler up front that most folk will assume is an oil cooler but guess what.......???? It's a feckin fuel cooler....!!!!!   If you scroll back and see the fuel rail, it has two -6 take off spiggots, one feed and one going off to the fuel cooler before it makes its way to the regulator. I came on this site and beam trawled for K75 issues about two years ago and hopefully have addressed all that can go wrong but then.......!!

So today was a milestone, it ran up a treat and I rode it to temperature with no issues, leaks or handling anomalies. Infact I'd like to point out that the handling was the biggest surprise, the seat height is way too high but the front end weight distribution is bang on, no wibble wobble at all, only the usual semi unsurities that TKC80's give on tarmac so dead chuffed with it's first test ride....
