cylinder numbers

Hi guys and gals i am new here im dave and i am in bristol uk i have owned yamahas in the past an xj650 a 750 and 2 xj900 diversions, i have just acquired a xj750rl which i am told is quite a rare model which went mainly to canada. I bought this bike on ebay almost totaly dismantled. I have started my rebuild and i have my first question my ht leads are labeled 1-4 but which is number 1 cylinder is it as your sitting on the bike or viewed from the front. Hope someone can help. Cheers. Dave.

 

if you're sitting on the bike and looking down at the engine number 1 cylinder is the left one

All xj's are numbered left-to-right as you're sitting on the bike.... 1 on the left, 4 on the right.

Now to help you, your 750rl is indeed a precious find. You will find a lot of info available for the xj900 Seca, and that will be a big help to you--- the 750rl is basically an xj900 Seca but with a 750 in it instead. Virtually all parts interchange, very few exceptions.

 

Many thanks for your info perhaps i can pick your brain in the future. Cheers Dave.

 

Old thread but I have a question regarding the numbering of the wires. As wires have nubmers 1,2,3,4 but firing order is 1-2-4-3, so in which order wires should be set? Are numbers on wires just representing cylinders not firing order?

 

Wire get put on like this:

when you are sitting on the bike,
Number 1 is by your left knee
Number 2 is next
Number 3 is just to the right of center
Number 4 is by your right knee

One of the coils fires #1 and #4. The other coil fires #2 and #3

 

ok, thanks for clarification. I got messed up when I started to think that should wires be set according to firing order not accroding to cylinder numbers.
Like: one coil would control cylinders 1 and 3 and second coil would control cylinders 2 and 4
