Yes I'll start a new thread. Some quick answers. Yes runs well now. idles smooth, starts well when the day is hot or engine is hot. Ethanol won't vaporize well when cold so I use a little petrol squirt bottle to start from cold, first kick usually. Injection timing is critical around transfer opening. Injection can be staged to minimize fuel loss out the exhaust, at least a lower engine speeds. Throttle uses a TPS. Crankcase pressure is sampled by a small valve connected to the crankcase, is only reads pressure ( or vacume ) when the injectors are on. So far only "seat of the pants" tuning. Yes rotary valve case moves with RPM ( this is a very good feature for a rotary valve engine). The "new" engine will be a made up unit ( for the YZF ) . I'm also doing a "converstion" for a YZ250 T for the local Yamaha shop. I think it will be too dear to sell as a kit, but lets just see if it works first. Yes I have access to a dyno but they cost so I've decided to get it tuned as close as I can first.
