I recently purchased an 81' CM400A hondamatic. The bike breaks up when you go to give it gas in first but if you switch to second it will move but will bog a bit. Looked through the shop manual and saw a fix being to replace the torque converter. Purchased one and replaced the part but now I have another issue. The bike has issues turning over. I bought another torque converter thinking the part was the issue, but the issue remains. I had the battery checked as well and its not the issue. I have since tried to replace the torque converter to the stock part and still have the same issue. Following the manual to the T and I am wondering if there is something I am missing. I am going to buy new roller bearings hoping that may be the issue. Looking for any assistance regarding this issue. Thanks.
