£120? pfffft
NO.1;
Washer in the variator, roughly a cm in lenght (similar to a spacer) is used to stop the variator opening to its full height (i.e reducing speed)
12 or so transmission cover bolts come off
on the left you’ll see the variator, on the right you’ll see the clutch/bell
(both held on buy single nuts)
simply undo the variator side nut
(ideally you need a locking tool which i will happily loan you? or something like a impact wrench will work fine)
and the fan plate will slide off, followed by toothed plate etc.
then you simply slide the restrictor off the crankshaft and slide the plates back on (making sure the belt hasn’t jumped out of the clutch, the belt will sit slack between the plates) and you tighten the nut back up.
transmission cover back on and your done.
No.2;
Exhaust restriction, to meet all this euro restriction crap. the exhaust will have a restriction in the downpipe section off the exhaust and depending on the year will have the SAS system fitted (another pipe running off the exhaust back towards a black box on top the engine, recirculation system)
so exhaust is held on by two nuts on the cylinder and two bolts onto the engine case, simply losen these four off and the exhaust comes off.
when you look down through the pipe you will see a sort of cone in the pipe (the restriction) this needs to be taken out, upto you how you do it (a dremmel would speed it up alot).
if the bike has the SAS system, PM me and i’ll walk you through how to remove that properly.
NO.3;
again to meet all this euro rubbish, out of the factory the bikes run as lean as they can safely, so the carburettor needs upjetting.
the carb is attached the the rubber manifold and to the air box usually by jubilee clips, simply loosen these so the you can detach the carb and turn it on its side (all fuel lines etc can stay on)
when on its side you will see the float bowl, held on by a bolt (bolt might not be there depending on model of carb) and two screws, loosen this off and fuel will poor out, 200ml maybe.
directly in the middle of the carb will be the main jet (gold in colour and the biggest) that will need to be changed to a slightly bigger size
(off the top of my head i cant remember standard size but i will find out and let you know)
then all back together.
free to enjoy the 45ish mph as 30mph really isnt safe on uk roads
