It is a fantastic kit, I don’t have much to complain about. Most of the changes I have made have been down to personal preference. This kit took quite a bit of fettling, as we bought it second hand we could not get many replacement parts when things did not fit correctly. If you buy kits directly from STW they are always happy to replace a component of it is not how it should be.
I would recommend a new mechanical lubricator, and springs on the slide valves as two definite changes that will drastically improve the engines performance.
