Looking really well Lar. Some proper bars and she'd be reet lol
I'm sure I'll regret it when the aches and pains set in, but those adjustable clip ons are staying. They're a really nice bit of kit and suit the bike.

Time to have a look at the electrical tray and battery mounting. Tucked into the seat unit seems the logical spot.

I just measured width, depth and height, never gave a thought to the frame taper and the width at the carb tops. That'll teach me, but it's all part of the experience.
I'm warming to the injection idea now, and I have most of the stuff I need anyway so it'll be a shit load cheaper to convert it to injection than to buy another set of carbs, jets and dyno time.

They fit well is that 1250 Blandit Bodies ?
Yeah, straight into the boots with no wrestling or twisting.

That looks the bizzo Lar
Part of the reason I chose that colour for the frame was the ceramic coating on the exhaust and the Cerakote on the engine cases.

It's just the right build to use up a bunch of stuff that I've had for ages waiting for the right project to put it on. Then you realise unless you get your finger out and actually use it someone will chuck it all in a skip before your ashes have cooled.

As a moral boost and to make sure I don't run into alignment issues there trial fit of the Cowley exhaust.

If that pic you posted was the bike in original form ..Its got a 2 smoke in it
Yeah it was at GT750 triple originally, and whatever happens I won't be putting one of those awful creations back into it.

Following the long standing OSS tradition of 'in for a penny' there's a fuel injected air cooled engine coming to a Dresda frame near you.

Try some 36 CV's.
CV's are worse (I have a few sets here) as they're wider at the diaphragm housing. I suspect the GS1000 had smooth bores which are much narrower at the top. The original triple would have been fine.
Throttle bodies will fit, but I didn't want to go the injection route with this one. Injection, find smaller carbs, manifolds with twin carbs, or change the engine for something else seem to be the only options. None are particularly attractive at the moment, but a bit of thinking space will put things into perspective.

Bollocks. There may be a solution, but still, bollocks. I really don't need or want the complication of an injection conversion.

Magnum Turbo only has a couple of mm each side fin to frame clearance at front also.
It'll be fine as it's snug between the sides rather than at the front. Glad I didn't put the head on first though as there'd have been some bad swears when it became apparent that it wouldn't fit between the rails and had to come off again.
-
It's a fiddle, but once the bottom end and barrels are in place then there's room to drop the head on before the mounting bolts go through.
I'll need to check alignment and make up some spacers for the mounting bolts. Then it'll be full steam ahead to get it to roller stage.

Snug is a good description. It definitely wouldn't go in with the head on, but it's in.

A little from column 'A', a little from column 'B'. Harvesting bits from a few engines to get tolerances etc to marry up nicely.
Bonus confirmation that there's another virgin crank available.

There all keepers
I really can't see me keeping the Dresda for any great length of time. It's been a great frame to use up a load of goodies which I have had for ages without having a suitable bike or project to use them on. I've also enjoyed finding various rare bits and oddities, predominantly from OSS members.
I'm really enjoying the build, and it should be a cracking end result which will get a few runs out, taken to a couple of shows and then moved on. The main reason being the riding position with the clip ons would ruin my neck on anything much longer than a half hour ride. So I'm enjoying owning it, but have no particular attachment to it which makes it fairly easy for me to part with it down the line.
I could put bars on it but that would look bloody awful on a frame like that IMHO as the tank and overall shape is a lot more slender than the top end of a Harris. It'd look like one of those push bikes from the '70s that we stuck 'cow horns' on.

Bang a turbo on and you get both my Harris is making 260hp and 148 ftlb. That's said I'm planning on building a very similar ET motor to this one.
My mate Si had a K4 1000 with a Yoshimura map on it making 180hp and the power delivery was brutal. There wasn't a lot in it in the real world riding on the road comparing it the the 230hp Scratcher at the time.
It will be interesting to see your comparison with these 2 builds.
All my turbo-ness will be going into the draw through, and I don't fancy the work or bills for getting two air cooled engines in a state to handle that sort of thump.
Yeah, I'm looking forward to seeing how they pan out, but I already know which will be the keeper.

The torque is what makes a big engine fun, I know I don't have to explain that to you,I would ALWAYS take 10 ftlb of midrange over 10 bhp at the top end
Roll on, and getting it in motion from a stand still.
A high horsepower, higher revving engine is fun, but it gets a bit frenetic. So ticking with the K1 GSXR comparison having the same power two or three thousand rpm lower down the revs with more torque should make for an entertaining ride without being as busy.
It'll be an interesting comparison to see the increase in torque between stock ET, the Dresda in the 150 - 160 range and the draw through in the 220 - 250 range.

As a point of interest, I worked out what it would cost to build an engine like this now from scratch. Five grand is the number I got to, but fortunately all the really expensive stuff and work was bought and done some time ago. This frame just gave me the ideal opportunity to put it all together along with some other tasty bits like the Cowley exhaust.
I doubt there will be too many air cooled engines getting scratch built to this or a similar spec now. It's just not viable when you can get similar output for 20% of the cost from an oil boiler.

That's going to be a healthy deep breathing motor, that'll fly in that chassis I'm sure
Lightweight race pistons, Upperton prepped bottom end, big valve head, stage 2 cams, Ignitech ignition and 38 mm flat slides. My target is to have similar power and weight to a K1 GSXR100 but with a shit load more torque.
Either this bike is going to exceed my abilities by some margin or I am am a riding god after all.

Have you got everything thing you need to pit it together today.
Almost, the main missing components are the stage 2 cams and slotted gears and that's purely down to me not being organised enough to order them before now. I also need/want to slot it into the frame without the head so that I can see if it can come off without dropping the engine or scratching the new powder coat.
Still got to sort the rear brake calliper mount and sprocket carrier along with spacers for the rear wheel. Just didn't fancy all the measuring and standing at the lathe again today. I'll get the tyres on the rims this coming week hopefully and then I'll be much happier with where it is.
The new timing plan is to get it as an engine in roller in time to take to Stafford in April if they give @Paulmthe nod for a stand.

Saturday lathe clean followed by making a start on assembling the engine for the Dresda. Aiming for 150 to 160 rwhp from a normally aspirated air cooled engine.

First piece of the spacer puzzle, get the swing arm in and central. Make up spacers which are accurate, but also look in keeping.
They need to contact with the inner bearing runners and leave a gap in the outer to take an 'O' ring.

Decent run back home?

I'm going to stick all of the electrical stuff under the seat/tail unit on a tray. There's not going to be loads as I want to keep it pretty basic, switchable fuse panel, ECU for the injection, starter relay (may go by the engine TBD) reg/rec and the battery.
That'll leave things clear up front for a small GPS speedo a rev counter and minimal idiot lights. I think it'll look better with as much free space as possible up front. At the moment (again TBD) I'm thinking a single large round headlamp. Tthat may change as I have a couple of other possibilities in mind, but it won't be having twins on it.
