Well, I’ve got a pretty big project but not a very big mechanical brain. Any advice or tips would be helpful, and I’ll be sure to share my build as it goes along.
Ive got a 2002 Honda 919 that I’m swapping the front end With a 2007 GSXR 750. Wheels, forks, top clamp, the whole 9. A few issues I need to work out. from What I’ve read, I need either a conversion stem and bearings to fit this. I ordered a conversion stem kit from cognitomoto.com , only to later find out that it’s meant for a 1982 CB900F - not a 2002. Would this still work though? I don’t know the dimensions of all the stems, hard to find. But if the steering stem tube on the frame is the same size on the 2002 then the 1982, I don’t see where I’d have problems.
I’m also swapping the headlight and tachometer/speedometer. I’ve ordered a fork mounted headlight with integrated turn signals, and that sounds pretty straight forward to install. Anyone have any experience installing the tachometer? I hear that you have to tap into the gas and the cooling system, sounds like a major pain in the arse. The only other things is remounting the ignition, which seems straight forward. Working on a design to mount it to the exposed part of the frame.

I’ll post pictures if I get any advice, or figure out anything helpful. Thanks!

that’s the stem and bearings I ordered. Will it fit in the 2002?

I think these folks used to be the go-to guys for replacement 919 stems - they might know.

Thanks but I actually ended up ordering a custom stem and bearings from cognitomoto. Ran we about 200$, which is a lot, but really not too bad, plus they’ve been very active and helpful.

Update: don’t try to use wooden pallets to stand your motorcycle. Thought it was secure, and about 5 minutes later I found my bike sideways with a massive dent in the tank. Gotta repaint the whole thing. Anyways, stem will be here on Monday, got the GSXR front end, some new handlebars, and a turn signal headlight to mount on the forks. Still gotta figure out how to hook that up.

That'll buff right out

still need to install mirrors and a speedometer, as well as a few touch ups but I really like how this turned out. I do not recommend a front end swap for people who are inexperienced with bike work. This project has drained my energy for the past few months, and I wish I could say it was fun, but it was more stressful then anything. If anyone has any questions about what needed to be done, I’ll try to answer the best I can. And any recommendations for performance or aesthetic upgrades are welcome!

I did this very same conversation on my 599.

Cognito Moto make it pretty easy to figure out what you’ll need.
