Hi all. About to pass my A2 test and considering swapping a newer engine into an old Ducati. Love the looks of the ducati, don't love the desmo services, lack of parts availability, and can't ride the Ducati on an A2 license anyway.

My two options at this point are a 2015 Yamaha XJ6 or a 2020 Honda CB650R. Both nice inline 4 engines that are useable for the street but fun if I want to push it. I know it will be a HUGE engineering job but anything is doable if you are crazy enough.

Any thoughts on which would be better? Having examined the engine mounts and frame of both bikes it appears the CB650R might be easier to work with. Plan is to buy two working bikes, and swap over everything necessary, rather than buying one part at a time.

How the hell are you going to fit a IL 4 in a space that a V twin fits in?

What Ducati is it that you like so much you'd want to ruin? Something like a 900SS only makes around 80bhp, so perfectly restrictable.

Or are you going full retard and actually want to strip the engine out of a proper bit of exotica like a 916 or 999 and replace it with a dull 600cc il4 from a UJM?

Even if you do pull it off, and that is a BIG "IF"

Have you thought about how you would insure such a highly modified bike on your fresh A2 licence, at what i assume would be a very young age too

let me get this right; you think Desmo valve servicing is hard yet you think you can drop an IL4 into a ducati frame and get it to both work and be legal?


good luck with that... Laughing

Why, just why would you ruin a Ducati like that? Putting a an l4 engine into a frame for a v-twin is going to be extremely difficult and you will probably end up with a bike that handles like crap and looks even worse. What might be more practical is putting a smaller v-twin in the frame, but that may still be difficult. By far the easier route would be to just restrict the Ductati. Any Ducati that makes 94 bhp or less as standard can be restricted.

Well yes, people tend to go out and drop a 300cc engine into a Grom or rebarrel their turd scooter to 80cc (not that I'd know anything about that!) but by all means take a step backwards...

Episode 1. We put a $99.00 Predator engine in our Honda Insight.

I had to check the date, but nope, it was only posted on the 6th, so it's not an April fool, but it has to be a wind up, surely nobody could be that stupid...................

CorriganJ,
Nobby (and others) make a pretty good point. The frame modifications required to fit an I4 into the Duc frame will be extensive. Why not consider a V twin or even a V4 for your project? I'm thinking SV1000 or VTR, or maybe a VFR1200 engine. Surely frame modification will be necessary, but at least you won't have to butcher the Ducati frame quite so much. I'm thinking along the lines of bending, balancing, trying to maintain center of gravity, etc. so that handling won't be adversely affected.

Whatever you do, please document your project and keep us informed on how you're going. The Show and Tell gallery might be a more appropriate place to post your project. BCF member Nope has posted an excellent photo log of his R1 rebuild. IMO, he has achieved the gold standard of project documentation. Good luck to you.

So much this. Desmo valve servicing is no harder than sprung valve servicing in fact it's probably easier in many ways.

I'm going to be watching this one with extreme interest... Laughing

yup, desmos are a fantastic design tbh and still easy to adjust. I wouldnt stay up late waiting for OP to deliver on this one though to be honest.

I'd have thought a dry clutch would be more annoying than weird and wonky Ducati valves Thinking

Why so? They can be a bit clattery I'll grant you but they're reliable and work well.
