Simple question but the answer might get complicated. I have been thinking of getting a 1998 EG w/EVO motor , only has 27K miles , Bike is like a New penny , never have seen a mint old bike like this one, It was taken care of for a long time. I have been told by many in this Forum that when you go to make an EVO quicker because of the Fuel Injection (MM Injection ) it does not take to engine changes(cam- valves -rocker work ?) but Exhaust or Air intake was fine and NO PROBLEMS . Can I put in a twin or a 103-110 or any Twin engine that is a done up engine and will it just fit in OR will it not at all and I must stay with the EVO ?

 

your joking right. the EVO takes to almost anything.

 

please dont twin cam it. i miss my 98 road king badly. i love my 06 too. but i prefer the evo over the twin cam so far.

Evo is a great motor. It'd leave it.

 

I say, you MUST stay with the Evo!

 

As far as I know the engine mounts on the case are different but they are some companies out there that make twin cams with evo mounts. Good luck!

 

Hell, That motor doesn't hardly have the rings set yet!!!

EVO's are strong old motors. They respond very well to any 'normal' mods (cam, compression, displacement, A/C, exhaust, EFI tuner, etc.). Some have experienced problems with lower base gaskets, but mine are still holding.

I have a 'warmed over' '88 with lots of enjoyed miles on it and am looking forwared to many more. It has a lot more 'snap' than my '05 T/C!!

 

The MM FI system is the same as the early TC's. I have the MM FI, and was able to mod mine fairly well, so I think the EVO should be fine.

 

as far as the MMEFI you can find a PCIII and cure that problem.......but if it ever starts having idling issues then just remove the EFI and put a carb on.......that was what i did.

 

Cool thing about evos is you can replace them with any aftermarket evo style motor, S&S, ultima... I'd say get a 100" plus ultima motor for cheap and throw it in there if you need a new motor. Or hell get an el bruto 127 in there and you d be set
