Cold Water?

Thermal shock...
While at some point, I used to think thermal shock could affect our operation, I have since moved away from that theory. The Rotax is set up for preheating cooling water as it comes through the tuned pipe.
But, cold air is denser. In your fuel/air ratio, you might find that the engine a bit sluggish in winter riding verses summer riding, when air is hotter, less dense.
Air temperature and altitude play a significant role in the jetting and tuning of our carbs.
I would say, give it a shot. You'll know from the response if it's too cold. But, before making that decision, allow your engine to warm up. You might find you'll need more choke until it's warming enough to lean out by releasing the choke. If so, starting at full choke, then holding your choke at half might help keep it running till it warms up.
But bottom line, you should have no problems running in colder temperatures outside a possible low speed adjustment open........:cheers:

Cool...
I've been thinkin of taking the GTX out but dag gum rain just won't let up.:ack:
Temps have been pretty good, anywhere from lows in the 50's to highs in the upper 60's, lower 70's but it's been raining now for about 2 weeks straight, with a day or so of a break but overcast.
I'll probably have to wait till after Christmas now (I got kids).
I need to pull my boat motor too but need a nice day to do it. I'm going to open up the cylinders to inspect but think I'm gonna do the upper end anyway. Compression is 135 on both but it's been 5 years since any real work has been done on it internally. So, it's best to do it when the engine is still together, verses one that has been damaged, making it useless as a core return........:cheers:

lol I wish i had the skilz you have; i am almost embarrassed to say but i just found and located the grease fitting under the shaft cover reading through your winterizing posts. got both engines greased 2 weekends ago:cheers:
I have been meaing to pull my father's GTX out of the garage for him and start it; while it is not ridden in the winter i don't winterize it because it sits in his garage here in ATL so it never gets below freezing in therer just start it up every other week with the hose and let it run for 3-4 min
I got my boat off craigslist and have never taken it to my mechanic (knock on wood) but i would really like to know how many hours are on both engines; wonder if they would charge an hour labor just to hook up their tool and tell me the hours lol bet the would; but your posts are very valuable and this forum is a great resource to us enthuiasts

Mecanics
It's always nice to hear that someone has benefited from the long hours of work that I've contributed to the forum. The forum has come a long way and now, has certified BRP mechanics coming in to help out. It's really great that these guys that own dealerships or work as mechanics, come here to share their knowledge.
Again, thanks for the Kudos. I do greatly appreciate it when someone has taken notice and taken the time to say so.:cheers:
