Although I've only got last years 8v 1000 to compare with, I'm at least hoping for a more responsive bike.

What have you done with the cooler pipes for the time being, installed a loop?Two Wheels Better wrote:Too right, Mike, and my project's just a pile of oem parts bolted together. Hardly a collection of one-offs like this.
I'm still not sure where to place, and of what version, my oil cooler will be. I've a triangular Ducati type, an automotive transmission version, and a larger motorbike type. It's all down to how to mount it as much as where.
I'm enjoying your build notes and look forward to more wheelie pics from your favourite tracks.
I've not yet decided between a triangular Ducati cooler, twin coolers from an R1200C cruiser, or an auto-type transmission cooler. I've had banjo bolt hoses made with rubber ends so that I can cut to fit when I decide. Location and what to mount the bloody thing to are the issues. I too half-decided on a 4" fan and lengthy hoses running back to the mostly empty real estate under the seat.Motorbike Mike wrote:I've had a really hard time finding somewhere to fit mine, it nearly went under the gearbox and I also considered fitting it inside the seat hump with a fan. I've used a K1200 cooler but I did have alternatives at the ready.Two Wheels Better wrote:What have you done with the cooler pipes for the time being, installed a loop?
How does the "seat of the pants" dyno feel? 130-ish BHP?Two Wheels Better wrote:It's worth a watch of Jay Leno's online video of him riding and evaluating Mr Romestant's bike. It's clear there's a level of refinement and tech to it. Quite a bit of fun and some real go, in spite of the retro-tech look to the machine. I too have seen it (Portland's One show last year) and in the 'flesh' it's an amazing piece of rolling art. The elbow intakes on this machine inspired the same of the Big Block, albeit, unpolished. There truly is a function to them; that of smoothing out the delivery of power, lowering where it begins and yet allowing it to breath at revs as well.
One day once sorted I'll dyno mine and get a proper reading of what the seat of the pants are suggesting.
I'm just glad that someone can see that I'm just trying to do my small part in keeping an old K going and taking care of the environment.K75cster wrote:Seems logical if I were the interviewer I'd give you the grant.
I'm enjoying this thread of yours Mike Especially if you use up all that old stock before it goes out of date

It probably is but if you want more rubber it's the only way to go.charlie99 wrote:looks about 30mm offset from centre line
but shouldn't be too big an issue
cheers
Motorbike Mike wrote:Hi, I did buy a Suzuki XR41 fairing but it was way too small-the size of a 250!
I also built an XRtt replica, sent for a fairing from Airtech and that wouldn't be suitable either, that's how I ended up using the Ducati F1, it looks OK when it's on. I can see what you mean about the RG & XR items having influenced the Cobas bodywork.
Motorbike Mike wrote:I don't know much about the Suzuki's but perhaps the 41 was much smaller than the 69. If you're after the fairing going around the valve and crank covers you'll have to extend it back anyway.
Do you have any pictures of your build so far?

Bit of an understatement, that :silent: I'm pleased you survived - what damage is there to the bike?Motorbike Mike wrote:Aaargh!
