I installed the TAV 30 series TQ on my mini baja, wow, i really enjoy the bottom end as well as improved top speed. it has been working flawlessly for 1 month, i have put many miles on it, however, I have just developed a really terrible vibration as i take-off, it smooths out at a little at mid throttle cruise, and shakes really bad at top speed, idle is fine...I have reasearched some possible causes, such as the engine is loose on its mount..I have not tried to trouble shoot the problem until i get some feedback, that way i have a checklist of possible causes to look into, any help is always appreciated, i sure would like to get back to it running like it did when i first installed the TQ...
