I have a 1999 Moto 6.5 with a carb problem. As there are so few Aprilia's around the chance of a secondhand carb is unlikely. Does the BMW F650 use the same carb? I know the Pegaso carb cannot be used (although the needle fits) as it is a twin carb.The Carb is a Mikuni BST 40 and it may be used in the F650 but I am not sure. It really depends what the problem is but I am sure most can be fixed by checking and cleaning the carb. Mine had a problem recently with cutting off when I pulled the throttle and the problem was water in the carb. It came from the tank infill breather tube that was blocked at the bottom of the tank. After drilling through the alu connector and cleaning the carb (cost me £57) the problem had gone and its running fine now. Also make a google search on MOTO 6.5 and you will find very helpful info (mostly in german) on a number of websites. ,

1i want to know how an where to fit a stage 6 proformance air filter to aerox.

On the carburettor, air being drawn into the carburettor is air that needs to be filtered. Simply remove the standard air box and fit the stage6 one. But don't forget; a stage6 filter will let more air get drawn into the engine, the more extra air need extra fuel to burn otherwise you will be running lean (to much air to fuel ratio). Running an engine lean will cause it to run hotter, if engine gets too hot it will cause the piston to become seized. So if your going to fit a free flow air filter don't forget to up-jet your carburettor.

I changed a couple dry roted fuel lines and now i'm getting fuel coming out of a hose that is connected behind the carb

is it a clear but maybe yellowed hose? cut at an angle where it ends? this is the overflow for the carburettors float chamber. the float is either not floating (popped) or not sealing the valve when it comes up to the top of the camber (worn/dirty needle) - it could also have been dislodged and is jammed open, you need top take the top off the carburettor and clean the float, check it is not full of petrol (the float) , clean the needle valve and refit (if the float is punctured you'll need a new float) give me the details of any numbers and words printed on the carburettor and i'll give you a link where you can buy a new float and a guide to servicing the carburettor.
I'd give you a diagram but carburettors vary so much its got about a 99% chance of being useless, get me the info and i'll get you a step-by-step guide for fixing the carburettor.

Carburettor flooding

The float needle is probably stuck. Lightly tap on the carb bowl with a screwdriver handle or something similar. It might get the needle unstuck. If that doesn't work you will have to remove the bowl and clean the float needle and seat.

Hope this helps.

Wont start keeps back firing working fine then went to take out next day and key turns it tries all that happens is it puffs out of exsort and wont go

2 possible problems:
a) Jets in carburettor are clogged. Clean out the carburettor and jets thourougly. Write down the settings of air and idle screws first to dismantle ( count the turns to full lock up the screws. DONT apply much force ).
DONT scratch jets with an iron wire or something like that, use only Carburettor cleaner!
b) Ignition timing is wrong. Here, 2 possibilities:
Sparkplug is dirty or worn, replace it.
Key in flyweel is broken. Remove the flywheel, check the key...

Hope this helps you in the right direction for your solution...
