Hi everyone!
I found this site from a member of another board and hope you'all can help. I took the opportunity of our cold snap to adjust out the flat spot (sorry, I didnt want to step on the other post). Anyway the carb is off, the cables are slack and I have Sam's carb adjuster on the primary shaft with a pointer wire set up. How is the dial suppose to index on the shaft? I screwed it on until the brass bottomed out, then rotated the dial face on the brass sleeve so I could easily get the wire to point to zero. For step 15 of service bulletin #9, if I twist the throttle grip to wide open, the dial is only showing about 60 degrees even though the butterfly is open all the way. If I work backwards from full throttle and the dial indexed at 80 degrees, closed throttle grip and butterfly reads 20 degrees on the dial. I put the carb tool on a spare carb and still cant get 80 degrees of travel. What am I doing wrong?
Thanks in advance,
Pete

Hi mate, make sure all cable adjustments are completely in. Throttle grip, metering oil and carbs as well. Also a important one is under the throttle there is a screw make sure its COMPLETELY screwed out. I had the same problem it was the screw under the throttle grip so would only go to 60.
I have done the adjustments but i still have a flat spot. and not to sure which way i have to adjust.
I get the flat spot at around 3.3 - 3.6k RPM. and not to sure which way to adjust.
Any other RE-5 Pros help out with my delema?

Ok, I check and I didnt get that screw, but now that I did, I still only get 70 degrees. In playing with the carb tool and my spare carb, the best I can get is 75 degrees and thats with no cables hooked up at all. Spec calls for 78 to 82. I'm going to fool with it some more tonight. Looks like I'll be calling Sam on Monday...

Did you get the problem fixed? If so, what did you have to do?

I am finally one with the cables......... ;D I think. After doing the cable procedures several times and no difference I talked to Sam C. and I could just see him smiling on the other end. Anyway, I did the full monty on the carb and cables after Sam helped me diagnose a faulty Secondary Diaphragm Assembly ( Should hold fully retracted for 20 seconds). Took the carb apart carefully and soaked everything in an ultrasound. Wasnt really dirty inside. After thorough scrub and soak with carb cleaners, it's amazing to see stuff drift off the carb and parts in the ultrasonic cleaner like smoke. Replaced Secondary Diaphragm from spares, lubed all cables well (per Sam), reset throttle pull cable. port valve pull cable. Sam sez you can leave off carb return cable, but I have mine set loosely. Oil pump cable gets done last (per Sam). Fired off and idled right at home. Reved it up a few times and fooled with the pilot needle setting. Took it for a short drive around the nrighborhood and it's like a different bike. I'll take it out for a real drive tomorrow, but it may not even need a pilot adjustment.

UPDATE.
After joy riding most of yesterday, I found I have a slight "spot" at around 3500rpm, but nothing like the chain slapping, backfiring that I had before. I think I'll tweek around with the pilot screw next weekend and see if that will wipe it out. If not, I'll start at the plugs, and timing and make sure they are 100%. Kinda nice not to have to sneek the throttle past the flat spot or hold on when it catches. Just roll on the throttle.

Very valuable information on this thread!! Thanks for posting it. I'm glad you were able to fix it and get the bike running so well. I look forward to any updates. I wish I could take a ride now but just the thought makes me shiver.  |

It is my opinion that cable adjustment is not as critical as it has been described.
In my experiance, the only way to truely clean an re5 carby is with an ultrasonic cleaner. (I have a commercial unit just for that purpose).
You can mess with cables until you are blue in the face. If the carby is not spotless, you will have a flat spot.
Again,
Just my opinion,
Best,
Jess

Hi Jess,
I thought I did a pretty good job at cleaning the carb with carb cleaners and my small ultrasonic (160w) cleaner. It wasnt really dirty when I started, but it certainly looked clean to me when I was done - body, jets, top, etc. While I dont relish going through the process again, is there something I might have overlooked in cleaning the carb or a particular part or jet to focus on?
TIA
Pete

Would somebody describe the famous "flat spot"?
