Old Boss Hoss bikes and trikes engine reliability

[Reality2025]

I see Boss Hoss bikes and trikes for sale that are 15 to 20 years old. Aren't these older 350 engines ready for an engine refresh. The age can't be good for valve springs and piston rings.

I do not see were a small block Chevy motor would need a rebuild unless it had a lot of miles or no service done to it ? most Boss Hoss I have seen usually have little to no miles on them, most of them motors were just gm crate motors, no big cams or high compression, & I do not think they get beet to shit , the guy next door has A Boss Hoss I bet its never been over 4000 RPM .

Springs and rings no. Would be more concerned with the rear main seal and intake gaskets leaking. If it has aluminum heads, block, water pump etc and the antifreeze hasn’t been kept changed, then I might be a bit concerned with internal corrosion, especially the freeze plugs. Unless it’s been obviously neglected and kept in a harsh environment, I wouldn’t be a bit afraid of it. Now riding it, yes I would be terrified of dumping it and breaking my leg!

With a small block Chevy its all about proper oil changes . They will run forever . I have been a Chevy guy forever and really never had a bad 350. I change the oil in all my Chevys at 3k. I dont run synthetic in anything but the Harley. Oil is cheap compared to parts and labor hence the 3k oil changes. If its got good oil pressure and doesnt smoke its good. Way back early there were some that had soft cams but you would know by now. Only way to mess up the valve train is with over revving.
