running on one
 

Am starting up new grid from now, 600ss running only on one pot.
I've tried everything to get this bloody thing running on two, it don't wanna know. I've replaced everything with new stuff (the whole electrical system). There is a great spark at the plugs but it just won't fire on the front. I'm completly out of ideas and dosh, and i won't be going to CC if i can't get in running. Engine is fine, just can't figure it out. Any sensible ideas are welcome (or cheap engine). Failing that would all the riders in class B pull a plug for the races next week. Just off to get my gun.

Must be fule if the spark is ok. Are you getting fule on the plug? :confused:

fuel going in, front plug is wet. Back cyliner is running fine.

1. What happens if you swap the plugs?

2. Are you sure that the braided wires from the pickups in the engien are going to the right CDI? Try swapping them over.


3. Have you checked the compression?

4. Go to pub

HTH !!

Are the valves set right??
Have you checked the woodruff keys in the cam sprockets and the driving pulleys??

i've checked eveything mate. I can't see why it wont work, bloody thing's doing my head in. she's on about moving the spare bed into the garage, thats how much time i've spent in the garage.

compression test is a must! or check valve timing !

You did manage to get it running on 2 at one point tho didnt you??
If that is the case then it cant really be mechanical, Got to be an elec issue somwhere,
Wot you need is a nice 620 mate
