    OP asked where we ride our big bore 2 strokes? My DT400C goes everywhere. Commuter, gravel road runner, even weekend touring. 2015 season was a little over 4000 miles. This year I got my '72 Suzuki T250 on the road so the DT only saw 2700 miles. (5000 between the two smokers)

    I found this one on Craigslist here in vegas. Purchased from the original owner, w/only 35mi. total . So he said. Came from a small shop/dealer in northern Utah.
    He had it stored in his shop/garage for about 15 yrs. Non-op. $1200.
    This was my first full frame off refurb. I build em to ride, not show. I have 44 miles/ 4.4hrs since. Quite the beast/tractor. Only drawback , compression is so good, it's a bitch to start. Wears my old ass out ! Maybe I'm doing something wrong. I remember reading about the CanAm's when I was a young guy. Not sure how plentiful these are. Anyone have , or seen? Thanks, G. 2016-08-22 16.52.45.jpg

    ^Thats a heck of a score! I had a '79 370 Qualifier. Same motor with shorter stroke. Swingarm was steel versus your alloy, slightly different body work. Enjoy that ride! p.s. Those are easy starters,usually 1 or 2 "nothing special" kicks.

    It's become popular to install these to make starting easy. I know they work on big inch Harleys.

    Thanks for the reply, it sure is purtty. If I do say so myself. Lol.
    Is there a certain technique for starting a big bore 2smoke? It's a left kicker.
    I've been thinking of selling just for the simple fact I'm having trouble starting the beast. Its stored in my apartment, dry. Haven't run it in over a year. Its definitely due. Thanks, G.

    On my '80 YZ465 (a notoriously hard starter) I turn the fuel on,lean the bike over 'til the carb overflows a bit,kick it through twice easy holding the kill button and then give it a good push through. I don't kick it I push the starter smartly remembering to follow through even if it starts halfway through. Not following through is what causes the pain to come. I also lean on a tree/trailer/building and stand on the pegs while starting whenever possible. I'm old and the knees find that easier to deal with. Jetting well even though (it can be) a major pain goes a long ways to making a big bore smoker agreeable to start and ride.

    Can am with a Bing? Hold the trickle button on the carb down until fuel runs out. Stand on the left side holding the bars. Right foot on Kickstart, no throttle, then jump up, come down on the kicker. should fire right up. if you are taller just kick it swift and firm. I had a 1978 250MX, always stared easy and I was barely over 100 lbs at the time.

    Thanks for the advice inmates, I actually use your techniques almost to the letter mudgepondexpress. Still a bitch though, especially when cold. Once running and all warmed up its not an issue.
    Thats a 38mm flat slide Mikuni from Sudco, jetted to match the original. Which works great when running. G.inV.

    Nice looking Husky. I spy a Mikuni on it, would you happen to have jetting specs handy?

    I just got the 360 and the 1974 250WR behind it in the pic a month or so ago (not a big-bore, so I didn't post a pic--nice bike though). I don't have the specs on the Mikuni. I'm going to take a look at the pilot jet this winter. The 360 runs great, but is a PIA to cold start. The 250 has a Bing and starts first or second kick. Apparently, hard cold starting is a trait of Husky big bores, especially with Mikuni carbs. I was told that a 45 or 50 pilot jet will make a difference. When/if I take the carb apart, I'll pm you the jet specs.

    Oh yeah, don't know if you noticed, the 360 WR had been fit with a full lighting kit (blinkers, horn, etc.) and had a title when I got it. It, and the 250, are tagged and street registered.
