Hey there guys

I have a 1988 80cu evo softail custom that's been imported from the states. It goes well but I want it to go harder... Is there anything I can do to accommodate this..

I have a mate that has a 1999 80cu softail custom that has had cam work done and flies. Would his motor slot into my frame... And would his swing arm fit mine as well as he has a descent wide tyre. Mine is still at 130..

If not can I toss in a TC motor in my frame 

Any help would be appreciated....

I should be able to get some photos up in the next few days hopefully.

So basically I will need his engine clutch gearbox hell I might just see if he wants to get rid of the whole bike lol
