XXitanium Posted May 23 Share Posted May 23 I don't believe this bike is real. I think this is a scam. I found it pretty easy to foil scammers in the past by calling their hand. I couldn't find this on the American. eBay. Doesn't mean it's not there, maybe I just didn't find it, derp. A local friend called me one time to drive about a mile and look at a boat for him. The boat wasn't there. The scammer said it was in Nevada. The story changed a couple more times and then we pretty much blew him off. https://www.ebay.co.uk/itm/166114871129?hash=item26ad37c759:g:a-QAAOSw81tka4a5&amdata=enc%3AAQAIAAAAwAu6Wxn6NQDzV02%2Fxeu0Xwe%2B1l1nUttlMHoMavETJzDaZk%2Fyy4223137s1nVl5Te%2B5eQIT5hyVOmUYuz96uadAmp8l6L4DUaLjdv4pss6Bx4p1qsXhOT08oPS6TOlvI35ZFWPda20EPNT5AkN5d6PwDuGvVp%2BFlV9IuCOV2lHGMEiv4HkbL8pfybKIofTPjjBVWhMMMdAF1IGT3GjT22nj9DVPQAsvCEgZjy5XehDXnppFqrdGdy08QZiH4DlaJwuA%3D%3D|tkp%3ABk9SR-rpppmJYg Quote Link to comment Share on other sites More sharing options...

CALCXX Posted June 13 Share Posted June 13 I happen to have a complete Honda CB750 motor with sand cast cases. Wish I had the bike to go with it. Quote Link to comment Share on other sites More sharing options...
XXitanium Posted June 13 Author Share Posted June 13 I have two almost complete CB900 engines. I also have near enogh to complete two other and a basket case with a CB913F overbored from a CB750F (would use one of the CB900 jugs and head). That sandcast is worth something to the right buyer.

CALCXX Posted July 15 Share Posted July 15 Bill, you do know the sand cast cases are nowhere near as strong as the die cast cases. Pre production novelty bikes for sure. Once again, wish I had not given the rest of that 69 SOHC 750 away. Collectors item now. Quote Link to comment Share on other sites More sharing options...

My CBX has been up in storage for about three years now. It's bugging me that it's not home for the summer. ...sad. Quote Link to comment Share on other sites More sharing options...

With the Ducati 999, the R model gets a stronger sand cast case than the base and S models. Quote Link to comment Share on other sites More sharing options...

It requires a lot more gusseting to equal the strength of the die cast cases. Die cast. no porosity. Ducati must have undoubtedly made a mold with extra gusseting. Otherwise, no. Hope it never fractures. Cast aluminum is extremely hard to weld. Especially if it is oil impregnated. Good luck with that. Been down that road.

Good luck with that. Been down that road. I don't think there's any inherent strength differences. It's easier to get perfect filling with a die, but a sand cast part can come out just as good if it's done right. Sand does make it easier to fuck up and come out with a defective part, a pressure filled die is much less likely to have voids/porosity problems. I think sand allows for a wider variety of alloys so there's a chance you could get a stronger part from sand, but not sure. Sand is much cheaper up front, dies are much faster and therefore cheaper for mass production. In both cases being discussed, sand casting was used for low production. Early prototypes for Honda, and small production for Ducati. For the Ducati 999R engine they wanted a deeper oil sump than the normal 999, I don't know if they made other changes. I haven't heard of 999R case problems. I also haven't heard of CBX sand cast case problems, but I've never paid as much attention to them. Being that it's Honda, they probably did the right things to not have problems. Quote Link to comment Share on other sites More sharing options...
CALCXX Posted July 16 Share Posted July 16 Lets hope so. I don't have much confidence in sand cast cases after a couple bad experiences. Quote Link to comment Share on other sites More sharing options...
superhawk996 Posted July 16 Share Posted July 16 Sand casting is still widely used for casting engine blocks, heads, etc. Even race engines. Die casting is probably more viable for bike blocks than car because of the very different shapes and sizes of the two. Bike heads are probably sand cast, just guessing based on the shapes involved, I've never checked. Quote Link to comment Share on other sites More sharing options...

That's old news, unless they've gone back to saying it does. And from reading the comments, he doesn't pan to eat it. Quote Link to comment Share on other sites More sharing options...
