    Small Block to Big Block Adapter Plate

    Adapts a gx390 style engine to a small block bolt pattern. I had it made at a machine shop. Made out of 6061 aluminum and is very nice. Works great. Just sold the bike it was on. Must go no need for it anymore........... $50 shipped.

    Block Looks Cracked

    I was trolling the CL and this engine caught my eye. It's not any bargain by a long shot and too many hoops to jump. In the top of the 9th pic it looks like a big split in the middle of the block. That would be upsetting to pay first and find a cracked block...

    Has anyone here done a Big Block Honda/Clone conversion on a TS50?

    I got one of the 420cc Clones that I'm contemplating putting on a TS50 project I have, the original plan was a mild built Tec H70 I have almost ready to go but now considering a BB...just curious if anyone has done this conversion and if they used the stock jackshaft mount with a 40 series...

    Predator 212 Hemi: How much lift until Block Clearancing?

    i am just curious 'cause i'm looking at custom cam sizes. Now what i specifically am looking at are 104 LSA which is what i want...tons of torque. And the custom lift gets crazy high up. Like .400" lift high up which i believe would take Heavy Duty dual springs and new retainers and possibly...

    hs40 block (Early 70s) with original black paint

    I need an HS40 block (on valves or crank case cover needed). The model year on this one is 72, but I'm not sure what the differences were during that time. The paint is important, but it doesn't need to be in perfect condition by any stretch of the imagination. I might need the crank too, so...

    Easier solution to the big block speed control

    Looking at one of the new HH60 motors I picked up last weekend its got this throttle control on it: That is a heck of a lot simplier than the massively hard to find 30199a part and its accompanying levers, springs and doodads. Just bolt it on with the head bolts. Done. It's part...
