I probably forgot something. The frame and fuel tank are basically the only stock parts...
The coming winter I'm going to paint the fairings, new exhaust hanger, Yoshimura Type A gearbox, IRC Race traction control,
install easily removable lights and license plate holder.

And the story: I started riding with a Honda NSR125. Sold it and didn't have a bike for 7 years. Then in 2008 I bought my GSX-R K1 750. The normal story, I was planning to keep it pretty stock - you know how it goes. Two years ago I found a cheap K5 1000 engine and a friend fully rebuilt it along with the mods. I did the 1K engine swap using Hybrid racing mounts. A year ago I meat a guy who had a spare K5 1000 frame with a title. He sold it to me for a good price. Swapping the frame was pretty much only reasonable way to upgrade to a newer bike. :)

Boy you have done quite a bit of work on that thing! Fantastic. I will be rebuilding my own 2014 750 that I crashed this season. Time to plan my winter project!! Cheers.

So, the thread pick is of the K1 750, right?

I love that scheme, my 97 750 had a similar scheme.

Nice bike, congrats
