F800GS german tuning

[DakarBlues]

Folks,

I yet to hear about the 800GS engine being tuned in.
Come on, this machine comes from Germany, the land of Alpina, Schnitzer, AMG and other potent tuners.
Why is it that nobody has extracted yet a quintessential 10 or 15 supplemental hp and flattened even more so the torque curve of this great stead?

Is there any tuner down there proposing, high performance maps, big bore cylinder of other performance bits?

Wasn't there an italian company doing this stuff? in sure there was, they had a bike that looked pretty cut up and striiped down to look more enduro than tournig. They didn't have anything full on engine wise but they had 18' wheels, cooling stuff ect.
My biggest want is something to fill the gap between the headlight and a high guard and look half decent, but ill keep dreaming.

I´m looking for the same thing...more power for the F800gs...SOS!!!

You can get 93 HP from the F650GS + F800GS with different cams and mapping, and 105 HP with different cams, mapping, airbox mods, and a full exhaust system.

German country code is +49 but you might have to dial a 1 before from South America, not sure?


Let us know what you find out.

I would love to buy a set of 900 ( nuda ) pistons........ then bore the cylinders.......re nikasil them..... and go from there with a pc-5....and auto tune...... Yum..... I mean wruuummm....

I'm idly toying with the idea of finding a nuda engine and building my own F900GS ... since BMW don't want to do it. Not sure about the legalities though.

The first step on my DRZ was a bigger carb, and BB....reaised it from 400 to 440.... The results were amazing... From 32.5 to 40 rwhp on the dyno..... Torque was fantastic.... Then later came the stroker crank.... cam's...even bigger carb... pipe , head porting.... and it now yields 55 rwhp...... simply a hoot..., So I can just imagine what the from 800 to 900 would do.... If there is room for the extra few mm's of bore.... I know a place that properly could do it in Denver, with the plating included..... no piston clearance issue... That I could think of.... Yum.....

[ebrabaek]

The first step would be to measure the cylinder wall....to make sure there would be enough room for the bore...... Anyone knows??????

interesting... already in touch, maybe sth for the winter...

I doubt if the Nuda pistons will work. The Nuda gets its displacement with a 2mm bore job and 4.5mm stroked crankshaft.

A 2mm bore job alone is not going to be close to 900cc. The bore is nikasil, so add $250x2 to have that done. A stroker crank may mean the piston pin placement might be different than the 800 piston.

A rebore and a stroked crank, along with a different firing order. (360 degrees vs 315 x 415 degrees) is going to require a different ignition profile and FI timing. I can only guess what those parts are going to run.

To expensive for me, so I will wait and see if BMW just uses the engine at some point.

I think they will. Triumph can claim more HP, though it makes no difference until you get past 100 mph. KTM is supposedly introducing a 1090cc adventure bike for 2013. HP still sells, though I would prefer a weight loss program.

I agree on the stroker crank part..... I don't want to go there..... But a 2 mm bore.....I would take in a heart beat..... That would be huge ..... about 850cc which would be significant.....
