Guys Corse coming back to life + extra pic of the rem brace

guy851

After a break and yet another complete strip down I have decided that it will never be perfect so I better get a grip and put it together for the last time and get a MOT and ride the bugger 😁
Forks, wheels, brakes all done in final version with all the ex Steve Wynne parts (wheels, discs, brembo billets + the rear brembo billet and hanger + 23mm swinging set up)
Dash coming along with additional oil and generator lights set in the top of the ECU case
Starter motor is in place and I will use the standard starter switch so I know just where it is in case of a stall and quick restart
Only an on/off switch so I will have to take the main fuse out sometimes 🙁
Left kill switch cunningly is now the horn which I will need for a daylight MOT
Pressure switch fitted to front and rear brake lines again for the MOT

And at last....the exhaust system - man this was such a lot of work and I have fitted it up so many times and stripped it again just to get the rear aligned...The deep sump conversion is nothing but pain - great for endurance racing but bad for setting a termi spagatti system around. I have some heatproof tape stuff next to the sump, really just as it so close i thought it might vibrate and make a horrid noise + more heatproof tape around the rear header next to the brand new Ohlins as the termi system is just too tight to fit the carbon heat shield.
Carbon termi sleeves were a lot of work but worth it as they are a unique shape + I cleaned up and reused the original bands (sleeves were from Speedmade ages ago thanks they look great now)

Little corsa battery just fits a 14Ah Lithium and needs raising up to clear the fairing + Mark T I think mentioned that if one uses the carbon fairing stays the water hose to the top of the radiator will foul - Yep it does and will need a little dremmel work to the left Corsa fairing/s

For those that missed the earlier posts the Corsa is slightly compromised so I can actually use it - I fitted started gears/sprag/motor. SP4 road loom so I can have a starter motor + I have a second set of bodywork with endurance lights and I will wire these dip and main beam one fine day. The only other compromise at the moment is that I have road shift but its very tight with the corsa rearsets so I may need to fit race shift so the slipper clutch should help when I get it all wrong 😎

Oh I also have on the shelf but have deliberately removed the Corsa radiator (seems pointless taping part of it over if I am not racing) and the mag alternator cover as I just think its pointless risking it getting eaten away by the mag worms and I dont want to drain the system in between races

Right lets try and get some pics up - I wonder if the seat unit was Mr Foggys?

Looking good mate!

guy851

Those last 10% of things to do take an age

I am very happy so far but keep forgetting how long things take

5 hours today prepping the carbon sleeves, repacking and putting back together

Where does the time go when you are having fun ?

Getting the brake and clutch lines so that I am happy + bleeding took much longer

But worth it

That's looking good Guy, I bet you're chuffed?
I know I would be if it were mine, I also appreciate the effort it's taken you to get this far.

A few points though...
The Mag' alternator cover when internally painted with the machine gun barrel paint I've posted about is now bullet proof, seven years now on my 851/916cc motor without any corrosion/or need to repaint it internally.
The Corse rad' I've got on my motor is just about perfect* on the road, other than on fairly cool/very cold days.
*In the heatwave we had a couple of months back it was keeping the motor (whilst on the move at speed) around 80-85C, this is with a motor making 128 rwbhp, what power is your motor making?
I know that where you've placed the reg/rec is where they were on the race bikes, but it really isn't that good, it's a bit too hot down there for the longevity of the unit so it could be placed in a better/cooler position.

Corse back to life

Thanks for the input Mr R,

I will get the mag cover on one day with suitable coating, the cover needs a repaint as well so its a bit or work and time is against me with work teenagers and life to be had so it may sit in stores for a while.

The corsa rad is another matter, I only have a couple of references and they both had tape over a section of rad on the road for all but a couple of days but then the weather has been kinder this year. The front and the V piece would all make better sense with the rad in too so I may well go for it. Have you got a fan fitted for those sitting waiting times in baking heat? I have wiring for a manual fan switch ...

Power ...well I dunno really the spec is hotted up SP3 is the closest reference point with more valve, G cams, zorst, open throttles. It was 110ish a couple of years ago without the benefit of the air intakes/airbox etc that I have now which should give a kick on top of the G's rush. I'm not in a hurry to spend more time/money on the dyno as i'm sure it will be plenty to play with

What thoughts on the reg mounting? The frame I have does not have mounts in front of the tank, but I need the air flow there anyway. I have an alloy finned heatsink I can fit directly to the back of the regulator...and I have a spare - where is yours?

Little bit more wiring to do next

Then will come the dreaded can I make any of these corsa bodywork sets fit nicely time.. Oh and the carbon tank is all sealed with caswell stuff so I need to put everything back in but this is a quick job 😏 Everything is painted and very very red (seat in the pics today is the No 2 seat)

Nothing seems to be quick at this stage

Hi Guy,

The Corse rad' hasn't got any brackets to fit a fan, I just keep an eye on the water temp' when in heavy traffic and try to always keep the bike moving.
Many years of practice commuting/living in London taught me how to get in and out of traffic at a fair lick, in several years now I've only had to pull over to let the motor cool down 3 or 4 times.
Taping the rad off in cold weather only takes a few minuets, once it's on in the Autumn it generally stays there until the Spring, unless there's a really hot day in which case it takes seconds to remove it.
For the really cold weather I've some 18g alloy plates that I cable tie over the oil coolers on my bikes...
Sometimes when I used to commute I had to use one of my fast bikes instead of my usual Winter hack.

A tuned SP3 motor with bigger valves and G's is basically a Corse motor, so would/should make Corse power and therefore Corse Heat...
More power = more heat produced by the motor, hence the bigger rad's on race bikes.
What chip are you running? 888 Corse bikes fitted with G inlets/exhausts can rev pretty high to make their power?

As I'm still running a 851 air box my reg/rec's still mounted behind the headstock, but I've got a complete set of Corse carbon air runners and 3 piece air box to fit when I fit my hot 955cc motor, so then I'll give it some serious thought??
The two forum members racing 888's at this years Classic TT/Manx have both come up with workable/fairly neat ideas as to where they've fitted the unit.
Stafford's hangs off the OEM helmet lock bracket from an alloy plate and Paul's hangs from a alloy bracket bolted to the OEM LH front subframe mount in front of the rad'.
Another place is up under the rear undertray/Corse breather box in the air flow, quite a few 748/9*6 owners have mounted them there with good results.
It just really needs to be placed out of the depths of the fairing and well away from the exhaust systems front header pipe.
Which is where yours is mounted at the moment.

What Chip

What chip are you running? 888 Corse bikes fitted with G inlets/exhausts can rev pretty high to make their power? - I dont know the spec but JHP did me one to suit the entire motor/zorst/airbox setup and put 11k rev limit on for me at my request - Crankcases are latest spec (94) on ball bearings so should be tough enuff but 11k seemed just fine anyway

I will look further at the rad and reg thinking - I know there is no bracket but thought fitting a fan could not be too hard. Although with the little alloy top bracket thingie + rubber top shroud together with the V piece it gets plenty of air

All good fun

Mr.R

Hi Guy,

I don't run the top rubber "Thingy"* but do run a late Corse "V" piece ( I've fitted it with some fairly coarse alloy mesh to stop the stones) that matches the deeper Corse rad'.
I've got a QB Carbon fairing molded from Foggy's NW200 winning 888, that weighs cock all and crashes quite well... I can swear to that fact! 😏

*I binned this part to save weight, the only downside seems to be that the front wheel fitted with a pukka Corse carbon hugger/mudguard can throw up a fair bit of crap over the underside of the headstock when riding down little Cornish lanes (not a big problem as I use sealed taper roller bearings down there), covering the reg/rec in mud etc.
My Physio** lives on a dairy farm (she's a farmers wife) at the end of a green lane over a mile long from the nearest little Cornish lane on the high hills of Bodmin Moor, in wet weather my bike's about 1" deep in cow shit almost everywhere. 😏

**All those accidents/crashes on bikes have come back to visit me BIG STYLE now in later life, I live my life now on pretty strong pain killers.

My Corse 888 has an MOT

😁😁😁😁😁😁😁

And I have the import paperwork done for the German frame 😁:

Now I have all the paperwork to apply for a UK registration plate

And then I will be able to ride her in the winter 😎

Its been a long journey and I still have some tidying/shaking down/suspension to set and getting the corsa bodywork neatly fitted

But really nearly there at last - anybody fancy an October track day at Anglesea or Oulton ?

Looking Good Guy, the deep sump crank case is a direct replacement or did you have to use the guts of other models?

Cheers from Portugal

guy851

deep sump

The deep sump conversion and associated internal parts are fitted into 1994 Corsa crankcases, the cases are machined to suit

Looks top job Guy. O'm rebuilding my 888 for trakday's and im taking ideas 😉

guy851

Deep sump

I cannot take credit for the work on the cases - this was all done by the previous owner who stll pops in to check how I am looking after his motor every now and then.

Looking good Guy, you must have got the Pledge out since I last saw her in the house 😉

guy851

Pledge indeed

Tis true that personal stuff, getting the lad through gcse's and work meant she was mostly on hold apart from gathering a few more parts

I had a two week break and dedicated a few full days to getting her finished

And getting some bloomin paperwork done so I can register her for the road

Should have a number plate soon

Nice! Where did you get the high level carbon brackets for the exhaust?
