Here's my take on this .When I had my '93 ultra, it ate a lifter wheel and trashed the motor.I had Harley do the reman deal on it to the tune of almost 4k. Now after I had time to digest this expense, I could have had a larger aftermarket motor with a longer warranty, then Harley's for about the same $$$.I then could have sold the original motor to offset the cost of the new one, and had a bigger more powerful motor for about 3k. To make an evo over 100cu in, will cost alot more then that with no warranty.,,
Yep, I agree.

Another option is to look into the Revolution Performance bolt on 85" kit. I have one installed on my FXR along with ported SE heads at 10.5 to 1 and some other goodies. After nine pulls on the Dynojet she's making 98.6 HP and 95.3 # of torque and has been super reliable. I found the kit to be very cost effective and might be worth looking into as an option for what you are looking for.

lotta good stuff here. I found a dyno chart on different equipment people put on. It amazes me with a carb cam and head you can gain 20-30 HP. best kit I think I found was the Revolution Performance bolt on 85" thanks to BuddyWMC... almost 100 HP! on their dyno.

Others that have responded know more than I but if you don't already have them, here is a suggestion
to wake up your 80' evo:
EV-27
torrington bearing upgrade (needed)
new hd lifters ( needed)
ez-change adjustable chromoly pushrods (should do)
even more to make it better:
good single fire ignition
possible head work
9.5:1 pistons
If you do the work yourself and shop wisely, the cost for parts related to the cam upgrade is not too bad, guessing maybe $120 for a EV-27, torrington bearing $10, ez-change chromoly adjustable pushrods $100 stock HD "B" lifters another $100 - A few hundred more you can have a good local indy shop do it and not have any worries afterwards. Be careful though, if the estimate starts going up pretty high , keep in mind a new Ultima engine delivered to your door costs less than $4000.00
This will give you pretty good performance and you can still save up for and buy a new Ultima motor for less than $4,000. delivered from Jireh. With Ulitma , you determine how big you want to go 100-107-113-120
