My RD 250 currently has all stock carburetors with the stock filters with needle clip position being in the center, the bike runs very well but on a stop first gear 1/4 throttle has a very distinctive bog unless really heavy on the rev of throttle before releasing clutch. The bike also has a good smoke trail on full 3/4 to full throttle.
Thing I have in mind to do is check my reed valves ( throttle bog)to see if they are seated. Maybe remove stock y boot to filter box and replace with foam pods.
Any suggestions would be great.
take carbs apart and clean the jet tubes and air jet hole in the bellmouth. sounds more like a needle /jet tube issue
Thank you, I still need to rip the carbs apart. I was thinking the issue was carb related also.
