Dr. Bob...I am new to this site. However, from readin many posts, I am estimating that you know quite a bit about motorcycles. I have an 84 Honda Sabre vf700s. Bought it cheap. Runs good, however, I recently changed the master cylinder for the clutch system. Since then, I cannot get any pressure in the lever at all. Im not a moto mechanic, so im sure im doing it all wrong. I did not bench bleed either, just dont know how, and the manual I bought just doesnt seem to be getting into my head a view on how to properly bleed the system., I actually blew the lines out with an air hose, because some dirt was in there. Theyre clean now, atleast. Other than that, the bike seems to lurch at higher rpms while in second and 3rd gear. Maybe this is a related problem? But I WAS able to get pressure before I changed out the MC. Your thoughts on this would be a blessing, if you have time
