No chit. Thats cool. I've been wanting to see a big triple in a pro. I can't even imagine 400 HP in that chassis. I'd be making sure my life insurance is up to date...lol

Union Bay Engine ported by Ruth power ,crank made by crank works.

This motor will make ~195 ft lbs of torque at around 8000 RPM.

Here are some more pics,getting close to the pipe stage,very very clean under the hood. The engine actually is perfectly center in the bulkkhead with the center cylinder.

Is there much clearance behind the carbs against the bulkhead? Who's engine plate is that? and is fastrax still making that one piece head cover? or is it from the old UB days? What modifications are needed to the top half of the crankcase to fit the UB cylinders and who did them? Very cool, looking forward to seeing this go together.

Yes carbs have good clearance , I welded a cover over the jackshaft so it does not rub on the intake socks. Fastrax no longer makes the head

Scott, where do you draw the line between impressive and I think I just crapped myself? :face-icon-small-hap Sledstew thanks for the reply. So a guy would have to find an old head somewhere, would fastrax be a good place to start? or do you know of any others? Did fastrax do the case mods for you?

You can draw it right in the dump in your pants. LMAO. THEN you'll know there is place to draw it.
