intermittent firing in one cly.

[BeeCanBanshee]

Ok so I finally got my bike together and took it out for a spin and it felt really sluggish. And my brother told me I was spitting gas out of one cyl. So this doesn't happen all the time. Sometimes it runs fine for a few minutes then starts to not fire. I switch plugs around and its still on the same side. Switched wires and still on same side. But I started wiggling the plug cap on the side not firing and it shocked the shit outta me which I though was odd. Anyway what's your alls thoughts? Also I forgot to grou.d the motor to frame so I will be doing that first and see if it changes.

Also I was going to check the plug caps,wires and coil well but they are basically new.replaced them about 4 months ago.

I recently has a similar problem. Got 2 new Ngk plug boots and it runs like a champ now

Don't ever rule out new parts as bad. Just because they are new doesn't mean they are good. Look at Ricky stator. Some are bad right out of the box

Yea I know it did run fine when I tore it down and it is Ricky stator's coil,plug and boots. Also I am picking up new plugs tomorrow. I'll check the above tomorrow and put new plugs in. Is it normal to get shocked by a plug boot? I thought that maybe since I don't have a motor to frame ground I became path of least resistance.that's why I got shocked.

I think you found your problem, RICKY'S...

[BeeCanBanshee]

Haha I hope that's it ill report back once I test them

Also I noticed last time I rejetted that my slides had a dimple in them. They are not in the same place and I waswondering if its supposed to be there or whoever did the idle screws drill into them? Just wondering if its normal

If you swapped plug wires left to right and the problem stayed on the same side you've ruled out any electrical problem. Make sure your carbs are in sync and choke tube is in place. If they are, then check the spark plug for water beading on the end. Water getting into that cylinder can do that.  Check for air leaks, and check compression.

[BeeCanBanshee]

Thanks madd. Yea it stayed on same side. I had just sync'd them and my choke tube was on as well. But also when I sync'd one sides cable is almost all the way bottomed out on carb top. That is also the side not firing. I will check comprression.

[BeeCanBanshee]

So I think I found the prob. I swapped carbs around and put a longer choke tube. On and the problem switched sides. Luckly I have a set of 28's that's going to be here tomorrow. I'll report back when I get them on.

Ok problem fixed. The carb on the non firing side had the float needle in backwards turned it around and it runs great.

[Jereme6655]

??? want to explain a little more on the float needle being in backwards?

[BeeCanBanshee]

Well while I was ay work my buddy tore apart my carbs. And he said according to the picture in the clymers the float on the carb of the non firing side was spun 180 degrees. So it was facing the wrong directio. I guess at idle it was letting enough fuel in to fire at idle but once the throttle was hit it couldn't keep up with the demands. So he turned it its proper way and bam it fires all the time now. I didn't think it was possible but apparently the float needle has to go in a certain way

[BeeCanBanshee]

Sorry not the float its self but the little float plunger was in 180 deg. The wrong way.
