GP200 engine (Indian from MB) no fancy stuff - Stage 4 ???
MB BGM Big Box Clubman exhaust
25mm PHBL Dellorto
102 main jet
50 idle
AQ264 atomiser
D26 needle (2nd clip from top)
40 slide
60 starter jet
2.5 needle valve
Air mix screw 1 1/4 turns out
Running through air box (Serveta type in tool box with air filter in)
All above is as recommended by MB
Other info -
Tried running without airbox (open mouthed, panels off) no different
Tried several plugs (NGK B8ES) all set correctly - no different
tried clip on needle at top slot - no better
tried clip at 3rd from top & slightly worse (spluttering just before 1/2 throttle)
Carb sits slightly at an angle - centre line as you look at it is in the 1 o'clock-7 o'clock position - like this / due to the fuel chamber being too big to fit it perpendicular
Put my old SH22 carb from the 150 I took out on it & it's fine (did this to rule out any timing issues or anything else) - I have no idea how the SH22 is jetted btw
From what I've read the atomiser and needle kick in at 1/2 throttle, so I think this is were I should be looking but which way ???
Mate of mine has suggested checking if the choke is fully seating off when it's off ???
I would appreciate any thoughts on this before I go & spend my life savings on different jets - anybody who gets it right first time wins a prize
