Re: 1981 CB650 #1 Cylinder not firing

I am blind. The black adjustment screw is there. I adjusted the Idle and its all good now.

Bike runs like a champ. I am riding it around almost every day now no hiccups. I am curious to see if it runs even better with the new jets.

Re: 1981 CB650 #1 Cylinder not firing

Had a friend clean the carbs out and adjust them by the book. That got all 4 cylinders running strong. The Bike still does not rev up when the Air Box cover is on there. Buddy says its running lean with the cover off, so I ordered 125 jets to replace the 120. It idles at 1500 when warm now. That is ...

Re: 1981 CB650 #1 Cylinder not firing

Got the bike back from the shop. It has new Plugs and Caps. Starts faster than i can let go of the button. It doesnt need much choke if at all. I have to hold 1/8 throttle for a minute to be able to leave it idle on its own. Ran somewhat good but it did not want to go over 5000 rpm. I did the washer...

Re: 1981 CB650 #1 Cylinder not firing

That is a great idea and it is easy to implement. I am hoping that when I get the call today from the shop it will be something like "We changed the caps / plugs and the bike runs perfect", but if it doesn't I will do this mod for sure. I keep reading about compression and the most of the ...

Re: 1981 CB650 #1 Cylinder not firing

Hello, So the guys at the shop started looking at the bike yesterday. They told me 130 120 120 130 for compression on warm engine, WOT and carbs ON the bike I went through all the threads involving compression and I am still a little confused. Will having the CV carbs on the bike while testing show ...

Re: 1981 CB650 #1 Cylinder not firing

Thanks for the replies ! The main problem is not confidence in my wrenching abilities but more of a space and time issue. I have a windy patio with a lot of dust flying around and a job that often leaves me out of town for a day or two, so its hard to start working on something that I might not fini...

Re: Need your help please - oil leak!

Hi guys I have the oil seal and o-ring changed, my first job ever on an engine and it went very well. I used a 16 x 1.5 bolt as a flywheel puller and it done the job. Happy to say it fixed my leak was a good learning experience. I will include some photos to help others in the same situation. Oil s...

Re: 1981 CB650 #1 Cylinder not firing

I am back after a couple of week of bad weather. Ordered new tires, new clutch and throttle cables and might make an appointment with a technician to do the Valve and Timing adjustments (I am not confident enough to touch those two yet) Tires and cables will be installed in a shop 3 weeks from now. ...

Re: 1981 CB650 #1 Cylinder not firing

Phew... Unscrew, screw back the Spark plugs. They went out and back in easily. I am gonna have a few beers to celebrate for sure. The weather is bad again, so I cant really do a lot of work on the bike today and maybe even in the next week. As soon as the weather gets better I will seal the airbox a...

Re: 1981 CB650 #1 Cylinder not firing

I am trying to relax, but it ain't easy :D There is spark on #1 I tested it against the block. #1 fired up right away after I pushed that rubber boot in the direction it needed to go and the bike Idled and ran good. I am about 95% sure now that everything will be resolved after I patch up that boot....

Re: 1981 CB650 #1 Cylinder not firing

Thanks for all the suggestions and guidance. I was going through the advises one by one. Changed the oil. Cleaned the electrical contacts (Under the left and right covers and under the seat) Now this is where I don't know if i am doing a good job. I just sprayed them with contact cleaner and scraped...

Re: 1981 CB650 #1 Cylinder not firing

Will get a compression tester. I found some really cheap ones in Canadian Tire. Will test the compression. Will buy new spark plug DR8EIX because the spec is #8 right ? And I will get the Iridium cause someone on the internet said they are better :D Will test the spark with the old and new Spark plu...

Re: My first bike. "Brand new" 1981 CB650

Managed to get the plug out. I have the 18mm NGK DR7ES. It had gas all over it, so it should not be a carb issue.

I created a new thread in the tech forum:

Re: My first bike. "Brand new" 1981 CB650

That is a NICE looking bike! Do you know how to check the date code on your tires? I'm sure you know that--even if the tires look good--you don't want to be riding around on 35+ year old tires. The plans for the bike are as follows: Work on it until it runs like new. Ride the heck out of it. I like...
