Check to make sure no pebble or bolt got lodged in between the motor or trans and the frame. I heard of this happening and it will transmit the engine's vibration right to your brain.
This all started when i came out after eating and the bike had a vibration the local shop said look into the primary i did so and tmax said bad tps so i ordered one i guess the wrong part i have a crank pin runout gauge on theway if i cant find the problem i will pull the cams and tes the crank runout if it is over 3% i will get a new engine instead o fixing this one oh well been riding sense 1963
not the first engine i have lunched haheha
Further..'.wtf' to me 1963I would have never opened up the pimary without checking the normal things like the motor mounts they are all fine the bike has a bad vibration when riding a lot of twin cams get a slipped crank after pumpung up the engine and doing jack rabit starts i do quite a few burnouts by posting here i found out the tbw bikes dont use a tps i will have the runout tool mon or tue if the runoutis good i will replace the throttle body if none of these work it will be off to the shop i am in arizona for 6 months then back to oregon so if no fix take it back to oregon on the 1st of may
