The bike in the ad is a Softail, with a custom rear mudguard...plus loads of other mods.
EVO refers to the Evolution Engine 1340 built until 1999/2000 when it was replaced with the Twin Cam.
The EVO engine in Carb form is pretty bombproof mine has nearly 100,000 miles on it has good compression and burns no oil.... Weak
points are hardening rubbers in the fuel system, engine mounts and you need to keep the plugs and HT leads fresh.... All easy jobs.
Treat them with love when cold, as they take a while to warm up... Rag it from cold and you will blow the rear base gasket.... Just warm it up....
HD has three big twin frame types....
Dyna - Twin rear shock
Wide glide/street bob/Dyna glide etc
Softail - "twin" mono shock with shocks under the frame
Fat boy / heritage etc
Touring - twin rear shock
Electra glide/Roadking
Each bike has it's own character ...some say soft ails do not handle well....
If the bike has FI then it's quite an old system, if it fails... £800 is coming your way for an ECU.... Most people convert to carb if the FI fails......
Price wise ... Umm....£6.8k gets you a lot of choice....you can pretty much get any EVO you fancy...
I though would say that £6k is a better price for that...
One thing... A HD big twin V5 and Frame /reg are selling for £2.5k for projects..... The EVO engine £1.0 and £500 for a gearbox....so that's £4k for the major parts..... so, at £5-£6 k you can't go wrong...
The EVO engine is about as maint free as you can get... Single carb... Hydraulic lifters etc... Just change the oil .. ( engine/tranny/gearbox ) and plugs every 5,000 miles and it will last forever...
The engine is also 100% rebuildable.....
