Ultra gravel-traveller. RC8´ed Adv-S...

[LocuL]

Hi

I´m in the mood for changes and economy is with me.

Its an old dream i´ve been hagling around with.

It starts with my 530exc is offroading very much. The ours are growing quickly and i´m getting better and better. I don´t get to use the 950 for offroad as much. My divorce made it possible for me to travel again and the lust for adventures on the steed is strong. I have had a good eye for the FJR1300 for fast, light, single travel. But the thought about i couldn´t travel offroad made me dump the idea.
Then i thought it could be great fun to build an offroad FJR. My thoughts are fast on the tarmac and smooth on the gravel. I have allways dreamed of having more power to travel fast on the highways.
Plans/ideas are:
1: RC8(R) engine(EFI)
2: Touratech tanks front and 2x10l back.
3: Giantloop, hennesyhammock, jetboil....ultralight.
4: 320mm front/rear rally suspensionmod.

I know a lot would ask if the engine doesn´t punch enough and sure it does. But i´ve been riding the bike for a LONG time now and would like to make som exciting changes.

QUestions are:
1: Does anyone have any idea if the engine could drop in with or without minor efforts. My maine concern is at the swingarm.
2: How is the gearing? Can i get the transmission to work at less speed(i do not need to trial the bike)?
3: Which kind of mileage can expect from the rc8?

Any concerns or thoughts about the project, please write it.

I´m well aware that the project wont come easy and it doesn´t need to. I will be going to ISAF later next year.

The big sump at the front & bottom of the RC8 might be an issue ...

If I was just divorced, I'd not waste my time wrenching when I would pick up a perfectly good 950 and hit South America with a handful of dollars and a boxful of condoms... just sayin'

I like your way of thinking... I'm in Brazil right now there certainly isn't any lack of exiting... adventures... to be had if I put it like that.

Certainly much more exiting than taking something that works well (like a 950) and making into something else. Life is short, no point in reinventing the wheel.

NJaaaa...

First of all we all got different ways to handle stuff like what i´m going through.
Second i wouldn´t be going to South America, i need to travel way more in the scandinavien. I like the mentality and it isn´t stupid warm.
Third is that i love to wrench and make my own stuff even better.

What it lacks in exciting adventures, i´m getting that in the green zone Helmand.

Keep it rolling

I would first see what I can do with the existing 950/990 engine before a transplant.
You can easily get 100hp on the back wheel on this engine. There is a member here claiming 130hp on his SE (powercell). I also think that 150bhp is not what this frame, suspension, swingarm etc are made for. Just have a look at how different the swingarms between the 950 and RC8 are.
Anyway, all i am trying to say, is that a pair of FCR carbs plus a well sorted exhaust system and fueling will be more fun, more useful and cheaper than going big.

I really don´t think that the swingarm should be in trouble with 150hp. When the the swingarm gives in its because you have been offroading and jumping the big pig. Ofcourse my thoughts.

U should know ...didn't u manage to break yours once already?

I admire your needs ..

But if your worried about mileage at speeds which i rekon i know you want to travel at you lookin at around 200 i rekon, maybe less, the sp1 gets around 160 at full throttle.

I know they are'nt in the same league but my 990 adv s with map get's about 180 k's before the fuel light goes on when i'm heavy on it.

Why not just bomb a 950/990 put safari tanks on it a gpr single system for even more room for fuel or a turbo
Or fit a duke r motor in it.

Best wishes on this one

I just put a pair of 39 FCR's on my bike and (while I'm still breaking it in) they f'n ROCK! That combined with the Aqualine tanks - I can go like a bat outta hell for twice as long as with the stock tanks. BTW - I am running Remus Ti cans too. I looked into the RC8 stuff while my engine was being rebuilt - and decided it was too top end oriented and cammy for an offroad bike. That's why I got the 39 FCR's and not the 41's. Pick yer poison for your riding style and environment...

1000cc bore, superduke heads and that topped with fcr´s would be the bomb, way better then a rc8 engine transplant i guess.
That with a custom and calculated exhaust system would get you a completely diffrent bike.

[BikePilot]

You might check to see if the RC8 crank, pistons, cylinders and heads could be fitted to your cases/bottom end. I quite like the idea. I doubt fuel consumption would be any worse than the carb'd 950 provided you get the mapping dialed in pretty well.

[StevenD]

that will not fit. the rc8 guts are quite diffrent from ours.

[LocuL]

Not that i´m any nearer the project but something got aside this day.

It is possible to mount the engine. The images is from Robie Peterson(hillclimber). As you see its a LC8 frame without to much touchup...






This is very good information.
