I certainly agree with you in that I have a problem with people giving incorrect info. As for my personal credentials I have put on over 30,000 miles in the last 8 years on 7 Yamaha snowmobiles. I have 1800 miles on my current short flap Attak with no temp warning light issues. Due to low snow totals we have nothing but hard pack conditions to ride on. Surely with the very long stretches of hard pack railroad bed trails in northern Maine I should've had issues with my engine overheating. Maybe I just have an extraordinary sled.
The person that originally posted wanted a fix to backing over his snow flap. Through my personal experience I gave him factual advice on how to prevent it. Isn't that the point of this forum? For you to say definately that people "will" have their temp light come on is just plain wrong. Some people may, but, it isn't definate when you choose to cut a few inches off your snow flap. People can make their own choice. I've put hundreds of miles on my sled with no issues (especially backing onto my flap). What I've suggested flat out eliminates the potential for a problem with the flap. I'm not going to say that no one will ever have a temp light come on as a result of shortening their flap anymore than you can say it definately will happen. I'm still amazed my sled hasn't just blown up given your info. Wow, am I lucky or what?
