Pictures finally loaded on my phone after I already made my first response. I see now you want to reduce and lengthen the output? You might find a fab shop with a welder and o.d. Grinder or lathe with centers that can pull that off. For 5 hp it’s probably not that dangerous/critical, but I’d still think it’s worth talking to someone who specifically does custom bike work and get an opinion. Good luck with your project!

To lengthen the stroke you will need someone that has a crankshaft grinder. I’ve seen stuff where people rigged offset fixtures and did it on a lathe before, but to be done properly it needs to be ground. Crank journals are very high precision. I’d call a motorcycle shop and find out who does their engine machining, or try to get in touch with someone who’s into motorcycle racing that could recommend a good engine builder. If that’s not done properly the guy in the saddle will be sitting on a grenade. when I was younger I was into road racing motorcycles and trashed a couple engines while learning. Sometimes you get big dividends by just going to a pro right from the start.

Outstanding buck, congrats!

Dang! Nice work and helluva turn around. Congrats on your goat Jim!

20a ham hunt. I also plan to pick up a leftover archery tag in case I see one while deer hunting in January

Well.... if that's the best you can do, I guess it'll have to work....

Nice goat, he does look like he's been eating good up there. Congrats!

Very cool! Good luck guys.

What specs are you needing for the bow? I've got an older bow that's all set-up I could let go very reasonably. Diamond black ice, right hand 70# 29", has sights, arrow rest & stabilzer, just needs a quiver.

Nice bull Hoghunter. Congrats!
