Where can i purchase the alloy casting that holds the right hand wing mirror on to the handle bars on a Keeway ARN 125

Aluminum alloy die casting is the casting process that injecting the high temperature molten aluminum alloy liquid into die cavity with high pressure and high speed for moulding. Features of this casting method are product precise forming and high production efficiency. However, the conventional die casting process is defective. Because the gas in the mold cavity cannot be eliminated effectively, the gas in the mold cavity cannot be eliminated effectively, and the inner parts of the casting can be left to form the defects of the pores, to make the mechanical property of the casting poor. In order to solve this problem, people use the method of vaccum pumping, that is, the gas in the cavity of the die casting can form a certain vacuum or negative pressure state, thereby reducing the inner hole defect of the casting.

Ooh..! It was a great idea. Its an innovating idea. you just careful while doing this or I recommend a mechanic to do this

That's the coolant overflow bottle. The cap has a dipstick on it.

manufacturer warranty is one year from date of purchase for workmanship defects,i.e. clearcoat peeling or chrome peeling or worm holes in the casting.

33 1/2 FROM HANDLE BAR END TO END, BUT I WOULD ADD 2"
TO MAKE IT 35" TOTAL

pay attention to how it comes apart so it will be easier for you to replace.
there are 2 torx head bolts near the end of the grips in a cast alloy housing which also holds the mirrors in place, undo the bolts and remove, this will let the grips slide off the handle bars but on the right side you will have to undo the adjusting nut on the throttle cable and release the tension to be able to remove the cable from the grip so you can slide that off as well

Has it ocurred to you that your wing mirrors are not the electrically folding type, most are not. The switch on the drivers arm rest for adjusting the mirrrors will have a separate position for folding if yours fold. The resistance to fold by hand is very stiff as you have to overcome the spring tension, even when folded by hand they do not fold as flat as you might think.
I purchased a 2006 Golf 5 GT Tdi last year it had £5000 worth of factory fitted options but did not have electrically folding door mirrors - hope this helps.

On the inside trim, you can remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. Then you'll need to manipulate the panel and disconnect the door handle linkage from the door handle and disconnect the wiring for your controls. Then you can access the bolts that secure the mirror onto the door

It's basically a case of taking the door panel off! (This is for driver and passenger sides). Firstly remove the screw holding on the black plastic cover where the mirror adjustment control is and remove the black plastic surround. There is also a circular piece of plastc behind the mirror adjuster, make sure you remove this (turn anticlockwise) otherwise you won't get the mirror out later on! Next remove the screw from the door bin, inside the recess in the arm rest part of the door panel and from behind the door handle surround. Carefully slide the door handle surround off (first towards the front of the car and then towards you). Once the surround is off carefully unclip the speaker wire from the back.

Once you've done all this you are ready to go - the door panel itself is held on by plastic poppers, there are around 2 either side and 3 at the bottom. Carefully unclip all of these so that the panel is loose. Then slide the panel up (there is a plastic fitting at the top of the panel which sits in the gap where the window is). The panel will now come away - be careful not to rip any of the thin foam like lining of the panel and also of the wires going to the speaker.

There are 2 more screws which hold the wing mirror on - unscrew both of these and the wing mirror will now come off. Make sure you keep the sponge padding as you will need this to help you hold the new mirror controls in place. Then its quite simply a case of fixing the mirror on with 2 screws and refitting everything in reverse of taking it off.

Good luck!
