  6. LORENZ added a post in a topic Yamaha RX1 Engines   

    For those that weren't aware the 2016 year 582 Rotax 2 stroke aircraft motor is very close to the same motor as the 1999 model year 670 Rotax minus cylinder bore, rotary valves and the 1 piece crank. The cases are almost identical. The 670 Ski-Doo Rotax is closer to the 582 aircraft Rotax than the discontinued 618 aircraft Rotax was. Some say they discontinued the 618 from the aircraft line beachside it was too similar to the $20,000 912 four stroke Rotax that came market in the same generation. 
    It would have been amazing to have had Rotax continue the 2 stroke aviation line with direct injection. It would for sure cannibalize the 912 four stroke line of engines and the current bottom line net income. I don't blame them from a business perspective.

  7. LORENZ added a post in a topic Yamaha RX1 Engines   

    Here'a a quick google search of the RX1 vs the 670. The 670 HO was legendary. 
    *********
    All 670s are not created equal. the 99 670 H.O. was the last rotary valve motor that Ski-doo would put in a sled. the zx chassis would not fit the rotary motors. The engineers at doo built that motor as the last hurah for the rotary and pulled out all the stops. Consider that it dynoed at 138 hp, nearly the same as a stock 2002 reed valve 800 doo. The pipe on the H.O. was a seperate part number only for the H.O. The only aftermarket pipes that would make more power were twin pipes. The ignition had a different advance curve. The clutching was nearly perfect out of the box. The standard 670 was nothing like the H.O. Nothing was quicker untill polaris came with the xc 700 and it would still beat that or the 2001 srx in 660'. I owned #243 Toni H. 99 670 H.O. and after that a 2002 mxzx 800.
    **************
    Yamaha suspension technology, that's funny. I had a 03 rx1 as well ad a 07 nytro. I would take the ride of my 97 mxz670 any day over those. the only thing that the yamaha has for an advantage would be flatter cornering. the rotary valve engines sit high in the chassis because of the intake . yamaha leaves a lot on the table as far as engine and clutching.

    i have owned 4 r.v engines that were all bulletproof. 10k+ on two of them. some people are installing them into zx and rev chassis sleds . the ho 670 is a reliably powerfull mill.
    polaris introduced their 700, which was quicker than a standard 670. the ho was a response to that engine. it was fast. the 03 firecats which are the fastest are incredibly fast . the ho actually had quicker drag times.

    I'm not sure if this 670 tune is full out race spec?

    The 670 is no joke, it out pulls the 912 when the 670 is detuned for aircraft use. I can see the 670 out pulling the Yamaha RX1 in a snow mobile race tune.

    If it's fuel and oil getting past the seal from the crank case your running your engine lean. We know what happens when 2 strikes go lean. Kind of a scary think to have happening.

    Strobe LED replacement for Avid's stock units
    I have these Wheelands and need a couple lenses for them. Rather than replacing the uber expensive glass lenses, I figured that after 25 years there would be some cheap LED direct plug and play eBay cheap replacements available?  
     
    Who has a lead on cheap LED replacement?
    The photos are from a bird that I walked by at Oshkosh this year, I have and same strobes and controller mounted behind the seat, and have 2 broken lenses. My bulbs look to be in good condition.

    They came in and I'm happy. I ordered from that eBay above, the tires and tube are from different sellers. The born on date stamps are from 2015 and are about a year old stock. The rubber looks pliable and like new.

    Drop a link to that thread For the lazy Ed. I'm interested in learning more about those VG's you have and how they compare to other brands. If they're the "good" one, I'll probably pick them up from you.

    Are those speed wings?  I'm on the hunt for some STOL wings for my girl, but, if your landing in the back country with your speed wing, I may be able to drop new wings off my want list.  What kind of stall speed and approach speeds are you seeing with those vortex generators?  Did they help a ton, they're easier to install compared to building or finding new wings 
     
    The gear looks like it's extended, what kit did you use, or are they custom one off jobbers?

    San Diego knowledge, help, and motivation wanted to bring my girl back from hibernation
    I need some finishing help in San Diego. I'm hoping for Avid/Kitfox builder knowledge. I need some keen eyeballs to help me go over my plane that has been sitting well stored and preserved since '94. She only has 21 hours on her by the previous owner builder.
    I'm in the middle of replacing my 582 with a 670 along with new fuel lines and fitting. Test run may come as early as this month. New tires are ordered and rubber bits have been replaced.  iPad integration is in the plans  
    I'd be more than happy to pay for an extra set of eyeballs and knowledge while wrenching on her.

    Mains
     
    They look to be the same size stamped on the side as my original AVID tires.  It was mentioned they're a little smaller, how much extra room am I going to have in the wheel pants?
     
    I think I'll be ordering that set from that eBay link, unless you guys see a problem?  Thanks for the good find gents.

    I'm really hoping somebody makes them still, or hoping the Kitfox 4 doors are the same shape and size?  Who has the lead I'm looking for?  Saw these one on a Barnstormer ad that isn't mine
