Fixing Motorcycle Electric Start Problems

Lovely bike, and thanks to you my clutch is sorted, carbs are still garbage though! Raising a glass to you from the Cotswolds, currently experiencing a gale 😂🍻🍻🍻

Carbs can be an issue. I experienced rough running with the Kat and spent about a year getting it right. I had good idle and good top end, but rubbish middle. Complete rebuild of the carbs and no better. Ended up being the ignition advance unit. I had hit a Kangaroo some years earlier and had to replace the ignition side of the motor which I did using second hand parts. To cut a long story short, the springs in the unit had got old and worn out quicker than the Kat had. My carb experience is replace the emulsion tubes and needles and check your slides are going up together - I used a vacuum cleaner for checking 😁

@whitedoggarage mine was running ok..ISH. Had the carbs balanced and on the stand ran beautifully through the rev range. Took it on the road and it bogged down when opening up over 3k. It was flooding badly. Replaced needles/seats, even worse. Diaphragms and slides all good. Replaced the bungs over the pilot jets, thinking of t could be pulling fuel past under load 🤷🏻‍♂️ seems to run fine on n the stand. Waiting for a dry day to test it. If it is tubes/needles I may as well have put some FCRs on for what it has cost me!!

@@tryordiegarage Interesting issue, the problem with running on the stand is there is no load on the motor. Maybe recheck the positions of the main jet needle clips, there are 3 or 5 (can't remember the number) grooves, and it sounds like it is in the main jet region where the problem lays. Bogging down means you would lower the clip position. I assume you have your float heights right. Good luck with it all, it has been raining here regularly of late, but your weather has been much worse than ours I see.
