Hi Bikeseamus ,
RE : TDM CDI , If you have the right CDI with the magic code 3VD on it ,it's plug and play .
If the code is different you've got one with a rev limit .
Hi Frog ,
The main jet is in the secondary carb, right hand side when you sit on the bike .
Which is accessed from the bottom of the carb, It lives above the brass plug.
Both drills are for the same jet ,First drill changes it from 165 to 180 2nd drill 180 to 190.
I've been looking for this since your first post , You might want to try it .
I nicked this ages ago off a website ............. I am not responsible for it ..............
The only problem I can see with it is the possibility of the mixture screw falling out !!
carb modifications. The mixture screw gets backed out(holeshot performance recommends 7 1/2 turns out from lightly seated),the main jet isn't adjustable,
you replace the 130 main jet from the left side (as you're sitting on the bike)carb with a Keihin 135 and screw it in all the way tight.
The midrange jet needles (both sides) get raised 1 notch, (this means the circlip goes in the second groove from the pointy end)
cut 2 coils from the constant velocity slide spring (right side)and re-install cut side down. Be sure to line up the diaphragm correctly,
there is a little tab on the edge of it that fits into a recess cast into the top of the carb.
The sync screw on top of the carb bank
controls the point after the low speed carb carb starts opening that the high speed carb begins to open,
crank it in a turn or two so that as you twist the grip, you'll feel the free play take up,
then the low speed carb start to open, then the added resistance of the high speed carb opening.
You want the high speed carb to open just after the low speed opens,
without as much of a delay as with the stock setting. This obviously needs to be set with the carbs reinstalled on the bike before the gas tank is replaced.
Lastly,
if yor bike is a Skorpion (Sport, Traveller, Replica Etc., not a Mastiff, Black Panther Etc.) Remove the black rubber snorkel from the top of the airbox.
Of course, all these modifications are recommended for closed course, racetrack use only. Wink.
Sounds a bit like what Bikeseamus has done to his Traveller.
