I know the same part number starter clutch (the part that has the trigger teeth on it) is the same part number from 87-97. I bet I could wire up a...
A1gatorz, as an example of Factory Service Manual mistakes, below are 3 pages from the Honda Manual for the 90-96 VFR750 bikes. It mentions PG...
Roger, your bike is an 87, right? Do you think you could measure your PG resistance?
I told A1gatorz to at least measure the coil voltage while cranking. I read about a guy who had all sorts of no spark problems and he kept messing...
Okay, I just heard back from Rae-San. He essentially says that the pulse generators are an on/off signal and that the resistance has no effect on...
I sent a email to Rae-San Electronics as he is familiar with several honda bikes from the 80's and speaks english. Same language always helps. :)...
It's definitely Kettering, you can tell by the wiring diagram. The ignition coils have a constant 12v source which means the ignition box has to...
Joe has an 88 and 89 set from good running engines and all 4 measure 290-300 ohm. Maybe we should start a new thread just to get folks to test...
From what I can gather, the 86 (and older VF750 bikes) used 450-550 ohm PG's and the 88-89 bikes had 200-400 ohm PG's. What if the 87 bikes were...
Here is a small sampling of pulse generator resistances: A1gatorz has 6 of the 87 PG's that all measure between 260 and 380 (is that right?)....
The air gap is not mentioned in a lot of manuals because the factory sets them up so you can't really adjust them, but like any mass produced...
I may have some bad news. I found a similar thread on these forums where an 87 bike had really weak spark and the pulse generators measured...
Just a note, I wouldn't call the ignition box a "CDI" because that is a completely different type of ignition system and I wouldn't want anyone to...
That picture looks correct. You don't need to check the key switch (not yet anyway), you need to check the coil voltage on the black/white wire...
The part with the 2 long raised sections is from an 86 VFR. One year only on this part. The 87-97 all look the same with the smaller 11 raised...
As a side note, if you lean the bke over to the left at about 45* you won't have to drain the oil. Once I used a rope around the frame and a tree...
4th, I mean the key ignition switch. The other is the kill switch. 5th, only the black and white. Check with key on only and then check while...
My old Virago had low voltage going to the coils. I think it was a 2 volt drop from the battery. It ran well, but idled bad as the coils barely...
Okay, I see. Your saying disconnect the ignition box wire from either the 2 or 4 spark plug coil and then ground that coil connector (with the key...
A1gatorz, your flat out wrong. Firstly, the factory service manuals do contain mistakes. It's not gospel. There is a list of all the mistakes...
