Rotax is part of BRP. They have the data unless Aprilla uses their own engine management system after purchasing the engine. But even then, very different intended purposes and tuning.
It does seem like a lot of small error or decisions that have added up against BRP here. Each on its own would not likely have caused all these problems. Its not a simple fix like drilling some holes. BRP is going to be forced to spend some money to fix or buy back.
Agree 100% that Rotax is part of BRP, partially why I suggested this route. Granted the Aprillia is a different machine, but one would suspect that engine parameters for items such as Air Fuel Ratios, EGT if available, engine basics such as timing fuel injection durations and so forth could be compared. Essentially, ensuring the engine is running properly, or better than currently and see if a drop in temps follows.
Has anyone been asked to test with modified exterior body panels? Granted it is not a practical fix, but do something that makes a drastic change to help find a course to rectify the issue.
Illegal or not, they should also get a means to be exempt from testing a machine with the converter removed.
