Dogbytes' R80 ST project

We go to Porthleven quite often, great restaurants! Yes, that's the street we're on. I've been meaning to pop in to see the place by Outback (- perhaps they need some welding or fabrication done!). I can probably make the seat subframe and fairing mounts without having to spend anything but then I really need buy a rear suspension unit and get the wheels rebuilt. That would be a great psychological move because it would look like a bike then. Thanks for the offer of help and likewise, although I've disposed of my machinery I still have my TIG and bench-fitting capabilities here. :)

It's worth asking him! he had a guy that did fig welding a few years back (did a twin pipe setup for my ktm) but that was ages ago and was just a bobbie on the side so...
Absolutely. getting it looking like a bike will spur you on i bet! sounds sad, but especially when you can sit on the thing you know?

Thanks for the offer bud!

cheers and best of luck!
 
Reality bites! Looking for a good home...

Okay, I admit it, it isn't going to get done! Life, the Universe, etc. just isn't co-operating.

It's for sale.

No reasonable offer refused.

Most of the info is contained within this thread, for those who didn't follow the process, in nutshell, the frame has been extensively braced and has removable bottom rails - 80 hours of my precious time, the engine is semi-flat topped and is 50mm higher and 45mm further forward than standard. I have Ducati Imola-style Half fairing and seat unit too. Most of an engine is here but you'd probably want to build a nicer one anyway.

Flick through the thread for details and message me for anything else you need to know. Collection from Cornwall.
 
Okay then... It's free now!

Free to a good home but you have to collect this week or it's going for scrap.
 
If it can go on a pallet I can get it picked up any day you like I'm not sure if
that will help you ,but let me know if that sounds like something you may fancy ,I would pick it up alas I would not be able too get down too you for weeks .
Regards Chris
 
I'll take that please. Can you PM me your details including phone number and I'll give you a call. Ta.
 
Gone - but not forgotten...

Okay, if I were of that way of thinking I might take this as a sign. A friend of mine, with whom I'd lost contact since before I even started this project (yes, that long!) came to visit me this weekend and has just left with the ST (oddly, I still think of it as an ST) in the back of his car. It is now out of the eyeline of SWMBO, which is good, but better is the fact that he wants to pay me to finish it off for him! Watch this space!

First thing one the agenda is the wheel rebuild because I'm not doing that myself. Black rims, black hubs, silver spokes. Next will be a rear shock. Something half decent Ohlins, Wilbers, what do you think? It's pretty much exclusively for track use, although it may occasionally venture onto the road on a sunny Sunday.

That'll give us a genuine rolling chassis. Next call is to Richie Moore for an engine...

:bounce1
 
That's better...

Wheels were dispatched for powdercoat and rebuild today.

Spoke to Richie Moore about the motor and gearbox and he's putting some prices together for me.

Rear shock. I've been looking at Wilbers 641. Any opinions on those? Anyone used one? Anyone got one to sell?

Just trying to think ahead...

Just imagine, for a moment, a day in the near(ish) future when 'Dogbytes' R80ST project' is finished. Imagine it standing there, all 300lbs of it, pristine in its silver and mandarin paintwork, shuddering gently as one of Richie Moore's finest ticks over with the precision of a Swiss watch. The rider (please God, let it be me!) flips down his visor and, with a brief glance over his shoulder, pulls into the pit lane of the Nurburgring...

Okay, there's a fly in the ointment! It's a big fly and it's not a new fly, so I suppose I should have swatted it at the planning stage. The fly in question is, of course, the final drive aka bevel box ratio.

Now, the one I have is probably a standard one (1:3.36) and, at 8000rpm engine speed, that means we'll top out at around 117mph. Back in the day there was a 1:2.615 ratio that would have given me, my target, 150mph - but, crucially, not in a monolever bevel box. Likewise the 1:2.91 of the R100RS. I've heard of a 1:3.00, which would give me 131mph which is certainly better than 117...

So, what is the highest available final drive ratio for a monolever? The operative word is 'available'. And should I, perhaps, have opted for a 19" rear rim?...
 
32:10 for the Mono g/s and still available new (just not cheap).

My Moorespeed engine is currently attached to a standard 100gs bevel box and I get a bit pissed off with the gear changes, its like riding a jap bike. It really needs a load to pull against so I'll be moving it to a project bike running a 2.9:1 bevel box

Thanks Rob - 32/10 (3.2:1) is an improvement over the standard 3.36:1 - but I've also read of a 3.0:1 (33/11) monolever bevel box any idea what that might have been fitted to?

I've found an alternative rear tyre which will help a bit, so with that and what gearing is available it'll still be shifting for an R80ST!

HPN mention a 3.09:1 bevel box too...

I take it the project you're moving your Moorespeed motor to is a twin-shock frame?

I think I'm just going to go the Wilbers 641 route and make it fit...
 
doh! i live like 3 miles away but missed this post about it being free! win some you loose some!

sounds like you got a good deal though :)
 
yeah will be nice to see it though and i'm sure he'd let you ride it which is a feeling, once you put so much time and effort into something :)
 
Went to check wheel progress today. Apparently the rims and hubs will be back from powder-coating on Thursday and Central Wheels still haven't sent the spokes. So it'll be another week or so yet - and I was starting to get all excited too!
 
Called a firm of 'suspension specialists' I found on the 'net about a rear suspension unit yesterday and was told that the guy I needed to speak to was finished for the day and would call me tomorrow (ie today). To give him his due, he did, three times! Once was fair enough, the other two were to correct things he'd said previously. On one occasion he told me he'd spoken to Wilbers (I was enquiring about a 641) and they'd told him that the outer diameter of the spring was 185mm!

Now, I'm all for people having a go but, FFS, please have at least some idea what you're talking about. Be in possession of a minimum amount of common sense. Do not talk about things you know nothing about - you WILL get caught out. And if you're a suspension specialist, please, have a look at a suspension unit. Better still have some of them to hand so that you can, at least look at one when you're talking to me.

No surprises then that they were more expensive than anyone else too.
 
That's better

Today, by contrast, I spoke to a very knowledgeable-sounding and completely unpretentious chap at Revs Suspension http://www.revsracing.co.uk/aboutus.php who has persuaded me, by sound logic, that what is required is a Wilbers 633 with ride height adjustment. £652 inc. VAT.

I believe the classic, black and silver, look is the way to go…

Progress - I just haven't seen it yet!

Apparently the rims and hubs are, at long last, back from powder-coating. The spokes, alas, still haven't turned up but should be on their way. Will try to get some pics later...
 
Whilst I'm on...

I need a fuel tank. I actually prefer the roadster shaped ones although, frankly, I'm not fussy. Anyone got anything they want to sell? Or swap - I've got a 24-litre one that needs a new home.
