Hello Folks,

a few pictures of my build so far. I`m using a divi 900 engine in my build with the aim to create a more contemporary version of the old xs850. I`m using a mix of modern bits such as a m-unit and an rfid reader to start the bike.
The hart of it is obviously the divi engine since the old xs engine is pretty hard to get.


I`m just about to have it running for the first time and i have some questions.

the original ignition coils are numbered 1-4, but in which order do i stick the on ? Do i start from the left hand side or from the right ?

i have seen on here the people plugged up the exhaust gas studs right next to the spark plugs. Any long term effects on that ?

Thanks so far i have a few more tech questions coming up shortly as the aim for this week is to get the beast started.

Blanking the exhaust studs doesn't have any long term effect, it is there for emissions.

firing order is 1243, 1 is on the left as you sit on the bike.

Tis True that the firing order is 1-2-4-3 but the numbers on the coil leads are the cylinder Numbers.
So the coil leads go 1-2-3-4 left to right (nearside to offside)

thanks guys

Good point Ken, I assumed everyone would know the Divvy cylinders number from 1-4.

If you don't you probably shouldn't be embarking on servicing your bike, but if you don't you probably don't know that either.

'appen tha's being a bit heavy there Bev . You can change oil, clean and lube chain, service brakes, change wheel bearings etc without knowing the intricacies of the coil lead numbering. I did.


(Unless your post was a veiled jest on the fact that there are 4 cylinders, not 1,2,3 or 6 or whatever.)

Point taken Shoddy, I shouldn't have said servicing. Though most people carrying out those tasks can count from 1 to 4. If you think firing orders mean we change the physical position of cylinders there's little hope for you.

My old boss was forever firing orders from the doorway of his office ....
