  1. Snowy winter on tap?

    Last year's snowfall was light in the southern half of the state, with Concord getting only 39.2" in the December-March season. December had only 3.4" of snow, and that tends to keep sled registrations down.
  2. Snowy winter on tap?

    On this day last year Skip started this topic by asking if early snow in Canada meant we would have a snowy winter. NOAA NWS forecast discussion for the next few days. Through Thursday: I would also be remiss if I did not mention that forecast soundings do show sub-freezing temps mainly above 4000 ft across the White Mtns. That could mean a large portion of the event may stay as frozen for the highest summits in the Presidentials. Thursday night: increased PoPs along the Canadian border in our typical upslope region. With this occurring overnight the ptype now once again comes into play. Expect snow to descend to 2000ft with the possibility for accumulation all the way down to the surface right along the Canadian border. Have leaned a bit colder in this area as this is where the core of the cold air aloft will be with the upward motion being just enough to generate some snow accumulation.

    You are totally correct.

    Maine has almost twice as many sled registrations as NH. It's been like that for years. In 2013 Maine had 80,000 registrations, while NH had 42,000. In 2018 Maine had 80,500 (+ 0.6% increase over 2013) while NH had 43,000 registrations (+ 2.4% increase over 2013). Over the same period, Vermont lost 18.2% of registrations, from 25,238 to 20,648. like all year-to-year comparisons, you can cherry-pick the years to reflect the desired result, but, at least right now, Maine and NH are still reflecting the traditional relationship between the two states' registration totals. Two or three years from now we'll know how price sensitive the non-resident sled riders are to registration fees. The Portland Press Herald ran a story (I used outline.com to access the story) back in December 2017 about the growth of northern Maine's snowmobile business. The story reported that "Registrants from Massachusetts accounted for 43 percent of the out-of-staters last winter, followed by New Hampshire (18 percent) and Connecticut (11 percent)." That would be 14,000+ NH sleds registered in Maine, and I'd guess that most of them were also registered in NH.

    Comparing Maine and NH OHRV riding areas is tough to do. OHRVs do best when operating over large areas of low-population, under-developed land that's owned in large blocks by relatively few landowners.That pretty much describes large portions of the western US, but not all that much of the northeastern US. Snowmobiles have another requirement, and that's a seasonal accumulation of snow that remains on the ground long enough to make snow trails viable. We seem to be a string of lower-snow, warmer temperature winters where it's hard to make and keep a base. To compare Maine and NH you have to consider human population densities, land type, available land area and ownership, and geographic location (with higher altitudes and lower latitudes being better). Higher population densities bring competitors for the use of recreational land, and more infrastructure, like roads, vacation homes, and shopping centers. I used the 6 northernmost counties of both Maine and NH for comparison. Together Coos, Grafton, Carroll, Belknap, Sullivan, and Strafford counties have 398,250 people living on 5756 square miles, or about 69 people per square mile. In Maine, Aroostook, Piscataquis, Pennobscot, Somerset, Franklin, and Oxford counties have 384, 157 people living on 22,776 square miles, or about 17 people per square mile. Land ownership is much more divided in the NH counties. Both northern NH and Northern Maine average 80"+ of snow each winter. Clearly, northern Maine has much more potential for motorized recreation, but long driving times to reach them is an issue. In a competition for sled riders, NH has the benefit of being closer to population centers and Maine has the advantage of being much larger with lower population densities. I question just how much speed limits or registration fees play into a average tourist's choice of riding area.
  6. Something different

    You've ridden in New England and Canada, maybe gone to Yellowstone or Colorado, and you're looking for something different. Alaska is a possibility, but you want really different. How about Svalbard? Svalvard is an island chain which is part of Norway and located well above the Arctic Circle, about the same latitude as northern Greenland and much further north than Alaska. https://en.visitsvalbard.com/things-to-do/activities/snowmobile Note the firearms on the sleds. You're required to have scare devices to keep the polar bears away, and advised to have a firearm. The good folks at NASA offer this advice on bear scare devices: "Noisemakers including air horns, pistol and pen launched bear bangers may scare a bear away. Pepper spray may work on polar bears, but has not been thoroughly tested." Maybe you could conduct some research on pepper spray while you were there. Oh yeah, NASA also says that "polar bears may appear slow and docile, but they are capable of moving swiftly and with purpose." It will be up to you to determine the bear's purpose. Remember the line in the Jurassic Park movie where a comparison between Jurassic Park and Disneyland is made, but the wise guy replies that at Disneyland if the ride breaks down the animals don't eat you. Yes, I think the polar bears would add a lot of excitement to a ride for even a seasoned rider. Just remember to bring spare gas. Update: I don't think that Svalbard would be a good choice for trail-side cooking. Probably best to keep moving.
  7. Snowmobile exhaust systems

    I agree that on road and off road vehicles are treated very differently. One common thread though, is that the statutes defined a testing procedure that was very difficult for law enforcement to follow. That testing procedure was recently changed for the off road vehicles and law enforcement should be able to more easily comply with the law. Here's the procedure for testing a street bike in the field. New Hampshire law limits the volume of motorcycle exhaust noise at different levels, depending on speed and engine type. 92 decibels when operating at idle speed 100 decibels for 3 or 4 cylinder motorcycles when operating at 5,000 rpm or 75% of maximum engine speed 96 decibels for all other motorcycles when operating at 2,000 rpm or 75% of maximum engine speed State law is specific about how and where motorcycle noise should be measured: by a meter held at a 45-degree angle approximately 20 inches from the motorcycle’s exhaust pipe, in an open test area free of buildings, parked vehicles, signs or other sound-reflecting objects. Fines for violations range from $100 to $300. There’s no exception for antique motorcycles. https://www.citizenscount.org/issues/motorcycle-noise The city of Portsmouth is attempting to work through the testing procedures. “We’re going to be paying attention and have the equipment to enforce the laws,” stated Captain Frank Warchol of the Portsmouth police department. “The initiative was put together because people were complaining,” he stated. The Portsmouth police department dispatched two officers to train with the New Hampshire state police to use new equipment for measuring noise levels from motorcycle exhaust pipes. Captain Warchol notes that the Portsmouth police department now has a decibel reader, an anemometer, and a “custom-made tool to take the sound readings at the 45-degree angle required for an accurate reading.” Recent changes in laws/regulations have made noise violations easier to prosecute for off road vehicles and harder to prosecute for on road motorcycles.
  8. SkiDoo fire hazard recall

    There's a safety recall on several 2017-2018 SkiDoo sleds with the 850 E-TEC engine due to a fire hazard. https://www.cpsc.gov/Recalls/2019/brp-expands-recall-of-snowmobiles-due-to-fuel-leak-and-fire-hazard-recall-alert
  9. Snowmobile exhaust systems

    What I'm suggesting is that the new regs simplify the measuring process, I'm not saying that there isn't a good deal of discretion in the stop. The old regs called for a measurement process that wasn't possible in the field.
  10. Snowmobile exhaust systems

    The first part of the new reg would seem to include all snowmobiles, including vintage: No person shall sell, offer to sell, or operate in this state a snowmobile which produces total vehicle noise of more than 82 decibels sound pressure on the "A" scale as measured using the Society of Automotive Engineers (SAE) J2567 standard. Back in the 1975 the regs called for a max of no more than 78 dB(A) from a distance of 50 feet while traveling at full throttle when tested under the Society of Automotive Engineers (SAE) J192 procedures. The new regs max of 82 db uses SAE J2567 which measures noise while the sled is stationary and at 4000 rpm and the microphone about 13 feet from the sled.This standard seems designed to simplify the work of law enforcement in measuring sound after a stop. Here's something from the IASA: http://www.snowiasa.org/wp-content/uploads/2015/06/2015-IASA-Sound-Test-Presentation.pdf 6.0 Procedure 6.1 The snowmobile shall be parked at the test site with an operator seated in the normal operating position, and the forward traveling path of the snowmobile clear of obstructions as required in 5.1. 6.2 The brake shall be set throughout the test. 6.3 The engine shall be started and run until reaching normal operating temperature range, as specified by the manufacturer. 6.4 The operator shall slowly open the throttle until a steady 4 000 rpm ± 250 rpm engine speed is achieved, while holding the snowmobile stationary by applying the brakes. 7. Measurements 7.1 The sound level meter shall be set for A-weighting network and slow dynamic response. 7.2 The sound level meter shall be calibrated and adjusted, if necessary, so that the meter reads within 0.1 dB of the true level at the microphone. 7.3 The microphone shall be located on the side of the snowmobile towards which the exhaust outlet(s) is (are) directed. This is generally on the right side. The longitudinal axis of the microphone shall be in a plane parallel to the ground plane. There shall be no physical attachment between the snowmobile and the microphone/sound level meter. 7.4 The microphone shall be located at a distance of 4.00 m / 157.5 in from the longitudinal plane of symmetry and 1.22 m / 48.0 in above the ground plane in line with the exhaust outlet. If there is more than one exhaust outlet. I'd guess that a lot of the real old stuff won't pass the 82 db limit, but we won't know until tests are done on the trail.
  11. Snowmobile exhaust systems

    HB 591 has been signed into law, and some changes were made to the snowmobiles rules around exhaust systems. It appears that a different SAE standard will be used, and all sleds must comply with that standard. No person shall sell, offer to sell, or operate in this state a snowmobile which produces total vehicle noise of more than 82 decibels sound pressure on the "A" scale as measured using the Society of Automotive Engineers (SAE) J2567 standard. No person shall modify any snowmobile in any manner that shall amplify or otherwise increase total vehicle noise above that emitted by the snowmobile as originally manufactured with the original muffler nor shall any person operate any such snowmobile. The provisions of this paragraph shall not apply to snowmobiles operated at permitted snowmobile events as defined in the department's administrative rules, FIS 1501.01(d). No person shall operate a snowmobile manufactured after February 1, 2007 that does not display on its exhaust system's critical components the letters “SSCC Certified,” a visible and unaltered certification marking issued by an independent organization, the Snowmobile Safety and Certification Committee (SSCC), that certifies snowmobiles for uniformity of safety features and noise levels. The letters shall be legible and have a minimum height of 4 millimeters. The marking shall be on the exhaust silencer, visible and legible to an observer by lifting a snowmobile hood and without detaching or dismantling any component parts. The markings shall be embossed and pressed or attached in a similarly durable manner to the outer surface of the exhaust silencer assembly, and shall be resistant to alteration. The markings shall be so affixed that it shall be difficult to remove, replace, or alter without detection.
  12. Free- Polaris speedometer

    While cleaning out the cellar I came across a speedometer from a Polaris Indy or TX. It's about 3¼" round. I tested it with an electric drill and it works, and it looks OK. Update: Just found the tachometer for the same sled. I'm leaning towards the sled being a TX. Didn't test the tach.

  14. Something to think about

    The damage to the rental sled would be capped at the cost to replace the sled (maybe $10,000?) The cost of a liability claim by someone you injured/killed, or property damage, through negligence doesn't have such a cap. I suspect that most people don't get the answer to these questions until after they have an accident.
  15. No new posts since 3/21/19

    Might be because your average sled rider has moved on. The die-hards may trailer to Pittsburg, but most will call it a day. Boating and ATV sites should be heating up.
