A Rotax V-Twin Question

[Homeslice]

Hello all. I am a newbie when it comes to v-twins and especially the Rotax V-twin. All of my riding, to this point, has been on motorcycles with fuel injected inline 4 style engines. My question is this: Does the Rotax V-twin require periodic throttle body sync'ing like the Yamaha FJR's?

I would say so my came out of sync and was covered under warranty at the time :ani29:

what are the symptoms of the out of sync ?

A Rotax V-Twin Question

I do not mean to piggy back on your question, but my question, on the Rotax V-twin is:


Does it require a period to warm-up?

Thank you and cheers and safe rides to all.
Cheers.

Required, no, recommended, yes. I think it is more of an issue on the SE5 than the SM. I routinely start and ride in only about 30 seconds but on the SM5 it's a little easier to feather the throttle while the engine is cold. I always take it easy until the engine is up to temp.

:agree: Don't have personal experience with the SE but a warm-up period is a good idea on any internal combustion engine. The colder it is the more important.

If you use a full synthetic oil that really helps. They say 85% of engine wear occurs at startup. A full synthetic oil greatly reduces startup wear.

The real debate is more in how to approach the warmup process. It is generally agreed (by the experts, whoever they are) that driving the vehicle easy is a much better method of warming than to sit at idle. This is the approach that I use.

I also have SM5 but i use the easy drive method. I let it warm up while i put on my helmet then I coast down my 1/4+ mile long drive and when i get to the bottom I usually have at least 1 bar and I take off slow and within the next little bit it has 2 bars and is warmed up (drive it like you stole it) :2thumbs:

Easy drive...

I let it idle for a couple of minutes while I get the helmet and gloves on then I use the easy drive method for a few miles... about 3 until I get to the main highway.
