Throttle springs are in progress. I tried to wind some samples on my simple spring winder but couldn't get an acceptable result so I ordered a few samples in different wire sizes from the vendor that makes the springs for my vintage fork upgrade kit.
The choke is also in progrsss, the aim is to make something that uses the stock KTM clutch master cylinder choke lever and maybe the stock KTM choke cable too. It may need some carb machining so would require the carbs to be sent to me. I'll try to avoid that but it may be unavoidable.
