I ran the same engine & front end combo, circa 2003-04. K1 fork is better than you might think. Give it a rebuild...which means replacing the oil seals and cleaning-out the grunge. Then refill using 15W fork oil. Experiment with the fill quantity. Increasing the fill stiffens fork action...going too far will cause problems, like hydrolocking before full compression can be reached. Following reassembly, fully compress a fork leg, then add oil until there's ~6" of air space remaining to the top. Repeat for the other side. Then allow the fork to decompress, reinstall the caps and test ride. You can increase fill level (fork fully compressed) to within 3-4" of the top. If you go too far, you'll get unwanted bouncing and an overly stiff ride. Go way too far and you'll lose fork travel. For footpegs, I've modded OEM Nice. It's a lot of work. The fixed pegs are ankle-breakers. I lop those off, then weld spring-loaded pegs in their place. Only other alternative is modifying , i.e. cutting, sectioning, welding-up, your existing footrest asm. I suppose you could cut the heel portion of the shifter. I've seen it done. Can't help you much with this one. I am sqaurely in the heel/toe camp and probably loathe the toe-only setup as much as you hate the heel/toe. There are a number of kickstarters that fit this engine. Takegawa might make the most sense for you, due to you location. Japan isn't that far, by air, so shipping shouldn't be much. Comb through Web!ke, they'll probably have cheaper knockoffs, too. A foldable lever fits these little bikes better than the OEM Nice unit. Those Trailwings are okay for dualsport use, though the rear will only last about 4500 miles. The stock drum brakes are okay, too. Above 55mph, you'll want to engine-brake before grabbing a handful of brake lever. Just make sure they're clean and in good working order. Below 50mph, they work quite well. With these tires, 17/31 is optimal gearing; run the best quality, full-roller, chain you can source. I run D.I.D. NZ3 series. And, lastly, replace the rubber sprocket dampers. with this kind of power, their service life is 5000-6000 miles. They'll still look good but will allow excessive sprocket movement on the hub nose. All-in, this ought to get you a 60-65mph bike that will sustain 50-55mph all day long...and somewhere around 100 miles per gallon/60 miles (100km) per tank. I have serious reservations about that carburetor...it's too big. The intake port is 22mm. Running a 24mm carb makes no sense. Best carb available is an MJN22. Best inexpensive carb is a Mikuni VM20. The stock CT70 K1 rear shocks are lame, too weak for an adult weight rider. Best shocks available are Ohlins & YSS...$750USD + shipping. Takegawa lists a set of Dax shocks, with adjustable compression, rebound & preload for $350USD...last I checked.
