Well it's been awhile since I've been on. I just bought a new TM38 for the 500 and was swapping jets into it and checking my settings. The new carb came with a 6FJ41 needle. Does anyone have specs of the stock 6DK3 and what would be a similar needle for the new carb? Or should I just run it and try and tune it with this needle? If it helps I have an '88 small reed with a K&N and an FMF pipe... for now. Get a bonus today and may be looking for a new pipe.
