Right cylinder not firing '82 GS300L

[Redman]

Thanks Redman -
I've measured the left boot and it's at 10.45 kOhms. Funny that they're such high values. So unless anyone can think of a reason why these should be 10 kOhms - sounds like it'd be wise to replace them, especially since they're cheap. .

Hum, both are about 10K.
Hum... oh, wait.
THat is s 2 cyclinder engine, ... it have two coils...one coil per cylinder?

On 4 cylinder there are two coils, one coil with wire out each end to sparkplugs, and caps for those are 5K.

Let me see what I can find.

>>later note: Am not finding what should be on the 300.

BUt should be printing on the side of the cap, the number 01, 05 or 10 will be the K ohms.
If it says 05 but measures 10K, well, then it is on its way out.
If it says 10, well, I dont know if it should be 10 or not.

Hi Redman -
Thanks for the assistance. Yup, two cylinder. One coil per cylinder.
fbody mentioned that 10k is expected, but I may as well replace since they're cheap.
I don't recall seeing any number printed... probably worn off.
Yeah, not a ton of information about the 300 out there

Worked on the wife's bike today (putting new wheel bearings in her CB100), so I didn't have a chance to make progress on the Suzuki.

Well, she's running again, and with lots of power

Most recent major things I've done:
- Cleaned the carbs with an ultrasonic cleaner, and carb spray on the jets/tunnels
- Replaced o-rings on float needle seats
- Set the float heights
- Tightened up, and cleaned battery connections (positive terminal was very loose)

Here's the carbs after sitting in a heated ultrasonic bath with simple green solution for about 30 mins or so. If you need to clean your carbs, find a friend with one of these! I forgot to reattach the fuel/overflow/vacuum lines before I reattached the carbs, so that was finicky putting them in afterward


The float needle seat in the right carb, was loose - which explains why I was leaking fuel out of the airbox. I've ordered some new o-rings, but it was such amazing weather that I had to do something to solve the problem. Did some creative thinking and sliced some fuel line to make homemade o-rings. Actually a very good fit, and the hardest part was cutting them straight. Only getting very minor leaking from the old float bowl gaskets and a stripped bowl drain screw.


I think I have some more tweaking to do with the pilot screws, because the RPMs skyrocket when the choke is on -- but at least she's running! Found a very good guide for carb adjustments here: Fixing Common GS500 Carburetor Issues


So I guess that solves this issue. I don't think it was ever an ignition issue -- it just wasn't sparking because the plugs were getting fouled. I believe the root cause was the right carburetor flooding due to the needle seat falling out.
