Do i see Walms having a nervous breakdown designing these pipes??  Would be a mean bike, definitely more custom then anything else here! |

I think for the good of the group and Mrs Walmsley, I'll save Walms a coronary and go with a more conventional "under the engine" route for the pipes!  I don't really wanna get involved in an underslung gas tank. ;D |

Yeah, keep it standard Drewski... ;D What you should do is make the engine cradle mount on that frame with a couple big long bolts. Pop those 2 bolts out and everything including the electrics comes out with it. Great for working on the motor in the winter eh.... or maybe with a piece of glass on top, one hell of a coffee table  Go Leafs Go! |

Maybe think about making the engine cradle inspired by the Duc truss frame |

Maybe think about making the engine cradle inspired by the Duc truss frame The thing I really like about Jaybuilt's bike is the lack of down tubes at the front of the engine. He hung the engine from the back mounts and then dropped a light hanger to the head bolts.  I know the H2 is probably considerably heavier, but I'd like to do something similar. The thing I don't want is to wrap the engine in a cradle. If that's my only option, I will make it into a coffee table!!  |

That's the part of his bike I didn't like... If it's a trailer queen beauty, but if you intend to ride the bike, I'd stay clear of it... Just my 2 cents |

If you consider the potential consequence of the "head" mounts breaking, it may have a nasty outcome. Think long term. Severity of failure outcome x Likelihood of failure occurance x Likelihood of failure detection = RPN (risk priority number) Useful when modifying motorcycle components.  ref: FMEA If you do a free-body diagram of the engine with a particular mounting method, you can determine what forces the cylinder studs (or other potential mounts) would observe when hanging it. Personally, I like this build thread, good for some idea's eh? kawasakitriplesworldwide.com/phpBB2/viewtopic.php?f=17&t=38218 |

PS, you need to finish the OLD plan, before starting the NEW plan. ;D

People fussed about the CBX when it cam out -- no down tubes and stamped steel wheels. I don't think it was an issue in the end.

Ya boys, I'm well aware of the "issues" here. I'm not interested in a "trailer queen" by any means. If after due diligence is applied, a decision is made that this CANNOT be executed with a reasonable expectation of success, I won't do it.  It's the same as the upper shock mount on my Mongrel. Several folks have stated flat out that it will fail. The people I trust say it should work. I'm no engineer, so I'm gonna try it and see. Rest easy. I'll be keeping one eye on it for sure!! I'm not always interested in following the masses. That's why I love bikes, and Triples in particular. In my world of Drive Clean, hybrid cars, etc, 2 strokes don't make much sense. It's my way of thumbing my nose at all that!! Lots of people will tell you you can't/shouldn't do something. I prefer to "walk down the path a ways" to see for myself. The "people" could very well be right. We'll see. Don't stop offering you opinions though!! I value each and every one of you AND your thoughts!  Don't be offended if I don't share them though! This came off as more of a rant than I intended! Sorry about that! (Geez, I blame this whole thing on Steve! He started this thread! ) |

I assume Honda ( ) would have done stress analysis, material selection and failure testing. Anyone heard new activity from Jaybuilt on his bike, improvements, failures, etc? It LOOKs like Honda supported the engine by the block, not the studs tho....  |

The difference between the CBX engine design and a triple is the CBX engine was designed as stressed member the triple engine wasn't built for that. I'm not saying it can't be done but there must be some way to utilize the front engine mounts. My buddy had a CBX and I saw the worst tank slapper one time when we where pushing it through a few twisties. He looked like he was riding a bucking bronco! Maybe Hilift will pipe up on the CBX's handling. With that massive frame I don't think that will be a problem. What about two down tubes to the front mounts and a single tube under the engine. Kind of "H" brace with the left side of the "H" mounted to the lower front engine mounts and the right side of the "H" mounted to the lower rear of the frame? |
