F800S-GST
Work has begun on the new F800. This is one of BMW's newest models, featuring a vertical twin cylinder, counter-balanced engine. It is very smooth & makes good power. This bike qualifies to race in the GrandSport Twins – GST class of the MOTO-ST Endurance Series. It will be running along side our R1200S in this years 8hrs of Daytona race in October.
Brett lets the F800 ideal to ensure everything is OK |
The finished system looks good and you can see the Quick Fill just poking out of the back of the seat |
Brett rides it up the ramp and down the street |
Back from his ride - it's a bit loud |
Ready for a test ride |
Just about ready |
It looks like the exhaust works just fine |
|
The muffler bracket if marked and modified |
The finished pipe is installed - now comes the muffler |
Chris welds up the new exhaust |
Jeff cleans the exhaust welds and Brett makes a wiring harness |
Chris starts to build the pipe from the headers to the muffler |
The pieces are taped together to check fit |
Chris and Jeff look at muffler placement |
Once they decide where they want it, they tape it to the bike |
The first of a dozen safety wired parts |
We kept the stock shock but upgraded the spring |
'Aluminum Bob' made us an unreal belly pan |
It fits perfectly around the bottom of the motor |
The stock gas fill was on the side of the bike |
Quick Fill complete with a vent from the original fill |
Looking at the F800's unique under-seat fuel tank (left) you can see the large hole that accomidates the stock fuel pump & pickup. To the left of that, the stock gas cap. At the top, you can see an "X". This is where the quick-fill will be located for racing, to ensure we get the maximum amount of fuel in the tank. (right) is the quick-fill mounted over the "X". This is where a passenger would normally sit (not any more)

To the left is Fuel Bottle, at the bottom is the new Quick-Fill awaiting installation & at the top (black) is the underside of the bike's fuel tank |
Jeff tests the new Quick-Fill to see how long it takes to fill the fuel tank on the bike. The faster it fills, the sooner we can get out of the pits & back on the track

Brett and Chris install the Quick-Fill at the back of the bikes tank |

Jeff fabricates a plate for the fuel tank breather |
Once completed, Jeff installs the breather-plate |
No part of the F800 is left untouched |

Looking down at the Fuel Injectors with the body off |
A very simple - but powerful engine |
There's not much to the bike's bodywork |
