On Tuesday, the weather was just too good not to ride. So I fired up the RE5, it started first time, and away I went. The bike's performance seemed a bit flat, particularly at low to medium revs, and although it hummed along nicely at 5000 rpm, that was almost full throttle.
Once home again I decided to check the carb settings, but oh dear, they were way out. No matter how much I tried to follow the adjustment procedure I just couldn't get them anywhere near where they should be.
However I fortunately have a spare carby which I have rebuilt with a kit from Rotary Recycle USA. This looked like the time to do the change. So on wednesday, it was off with the old carb, on with the new. This time everything adjusted perfectly. All the setting and angles worked out just right. With everything tightened up I pressed the starter button and it fired up nicely, but would only run with a bit of throttle kept on.
Stupid me,I hadn't wound in the idle adjuster. With that set, the bike settled down to a nice 1100 rpm idle speed.
Once the engine was up to temperature, I headed up the road. The bike pulled strongly from low revs and only had a slight hint of a flat spot at 3700 rpm. But about two ks from home, the bike coughed once then died. I was unable to restart it.Fortunately at about that time my wife arrived in our truck, so I got her to tow me back home.
Naturally, when anything like this occurs I check the last thing I did to the bike. All fuel hoses, vacuum tubes, cable adjusters, carb mounting nuts etc were tight, so I removed the spark plug to see if fuel mixture was coming out of the plug hole. What I found was NO Spark.
OK, time to check the ignition system.
The CDI was humming away ok, so I started at the points. They were opening and closing ok, minimal resistance across the points when closed, but no apparent continuity when open. Next I checked the coil.
The manual says 1 ohm primary and 1.5k secondary resitance. I found 1.3 okms on the primary side and 12.3K on the secondary. Suspecting this could be the problem I pulled the coil off my parts bike, however when I checked this coil I found exactly the same readings. Maybe the manual is incorrect?
Next I decided to see if there was voltage across the points when they were open and with the ignition on. There was!!! Whats more, on turning the ignition off I saw a spark at the plug. I then tried turning the engine over, and sure enough I had spark at the plug. I then replecd the plug into the engine, turned everything on, pressed the starter, and the bike fired up OK.
I hate intermittant faults like this, and on a 30yr old bike, it could be almost anywhere. Today, another perfect motorcycling day, and again the RE5 fired up nicely, It cruised just beautifully with no hint of anything wrong.
Some days life is just perfect.![]()
