no spark?

[howry]

hey all...
me again... soo first off, cleand the bike, the grees still there, but thought i should get the bike running first before major clean up. soo here is few things that botherin me:
1. is the fuse box:
red 20amp red
red/yellow(or red/white) 20amp red
brown 10amp brown
red 10amp red/white
have ya ever seen that?
2. no spark. tried to check if i got any life in that thing. soo before that checkd the compression, its the same on both sides, 7psi. but still the same. tried to kickstart few times, and no spark. what could be wrong? where should i look?

thank you ahead. your replies will be soooo appritietd(sp?)

That's a link from our "Tech" section....................which is full of much wisdom. You will find wiring diagrams also.

nuthin will give you 7 psi except a 1" hole in a piston....or a valves that are not closing.

update. sorry MOUSER and ya'll, it was on 7 but not psi, for the psi its around 100. so i did the following, checkd the coils, grounded the spark plug on the head sylynder, checkd the coil and cable leading to spark plug. all the numbers from the link that RETIREDGENTLEMAN gave are correct, thank you for the info by the way. could be its the generator? tho its turning but prob the connections arnt as good. any advice you guys can give me?

http://www.biker.net/79_6502f_parts/engine/cylinder.PDF found this one, and it says that my compression should be higher. guessing something wrong with the engine?
