So here is another question: what is the correct Position for the lower bolt of the rear shock? I have 2 different setups, one in the middle (locks like the stock position) and the higher one. On my 3XV I have mounted a 5mm ring below the upper mounting point which helps to get into the corners a bit easier. With the 4FL shock beeing mounted in the top position the distance from middle of the axle to a bolt on point of the rear seat frame is the same as on the 3XV, so should be the same chassis geometry ....

Update: after several welding and cutting sessions this is how the engine looks like today:
welding session...
1.pic
after cutting and more welding and more cutting its that..
2.pic
the reed case modified...
3.pic
reeds married between 3XV and 4FL...
4.pic
spacer plate and modified PV bracket..
The spacer plate is needed because the 4FL has a 105mm rod and I installed a modified RZ 110mm rod to fit (as the 3XV has).

No, the references are different!
Not so much staging, but the finish is extra on the 4DL ...
Also, you can easily make an SP box, better adapted to the sport. The gables are available ...

Sorry Toop, may be I do not understand correctly. So you say the gear ratios are different between the 4FL and the 4DL? Is the 4DL better to siut on a road going bike (no race bike!)? And what do you mean with "the finish is extra", is the manufacturing process better for the 4DL?

2nd 1.937 1.813
3rd 1.684 1.368

Hi @ all,
I have a different info about the gear ratio between the DL and HW (in german it´s called "FL").....they are similar.
Secondary ratio:
HW/FL = 16/46
DL R = 18/47
DL RR = 18/51
The SP-Version has a different gear ratio than the DL´s. I dont own any printed info about the SP but if i remember right, the 1st and 6th gear are longer compiled. Secondary ratio is the same like the DL RR 18/51.
Regards
Chris
