The TX650 came with a silly twin cable hand throttle, one cable for each carb. I bought a single cable throttle and looked around for a two into one junction box. Only one I could find were made of plastic or steel with no means on mounting them, so it just flops around under the tank with the cables.
Didn’t like that idea, so I made one from a small slab of ally. I bored a 14mm hole through the slab and ran a 5/8” UNF thread through each end on the lathe to a depth of 11mm. Next I milled a step and drilled two 6mm holes in the step for mounting it to the upper engine mounts.
The two end caps are also aluminium turned up from some round stock. One has a one cable inlet, the other takes two cables. I ran a 5/8” UNF thread on them and then ran my scissor knurler over them. Both caps are fitted with O rings as the body will be filled with grease for lubrication. Only the second time I’ve used this knurler since I made it about five years ago. It works well.
The slide I made from brass, 14mm round, for a snug, sliding fit inside the main body, and 25mm long. Through this I drilled three 1.5mm holes, then countersunk them with a 3mm bit for the cable nipples. I still have to cut three slots with a slit saw in the slide, so the. Cables can be fitted.
