Default 1993 Softail classic

Hey guys , so I got a rebuilt 89" ran all last summer great. Changed oil recently along with rebuilding my mikuni, and ironically I'm getting super crazy vibration at higher rpms now . Was wondering if anyone had any direction on where to look . Thank you.
edit: I did change my oil by using a purging puck to purge out all the old oil. First time using the puck , have done the purging before by taking off the oil line that feeds the oil tank and never had an issue .

Check for cracked or loose motor mounts, especially the top mount. Check for broken or loose exhaust and muffler brackets, too.

Were the flywheels rebalanced or was this a complete kit with new wheels? Displacement increase add's reciprocating weight, that'll produce new vibrations through the RPM range too.

Hey twizted... Yeah they are the new SS balanced fly wheels . It's back to it's beautifully perfect feeling solid mounted vibrations now! I was hoping I didn't jack up the motor by using the purging puck. I have a 93' electraglide also, can I use the purging puck the same way I can with the different oiling system ?

Never used one unless the engines apart already, seriously doubt it could hurt anything,
