alan bechard Posted December 12, 2005 Report Share Posted December 12, 2005 I am headed to Germany next week and will be working on my BIL's 96 Beta, although I think often the problems will be generic to bikes. Always having lived in the south I have extremely limited experince with operating in the freezing temps. On his last ride, he would give it the gas and it would go flat. He turned in the "airscrew" (I am not sure if it is an airscrew or fuel) and it improved considerably, it is now bottomed out. My initial thoughts are a small amount of water / condensation freezing in the tubes or passageways, or possibly just some trash that is coincidental with the cold weather. My advice was / is clean carb, drain / clean tank, check internal tank fuel filter, add or replace inline fuel filter, clean and service air filter insuring airbox is up to snuff, reset carb to "normal" setting's (about 1.5 out on that screw? anyone know a baseline?) and then see where we are at? Tips, tricks, advice and suggestions from those of you guys living in colder climates? Quote Link to comment Share on other sites More sharing options...
outlaw dave Posted December 12, 2005 Report Share Posted December 12, 2005 Hi Alan - The 96 Techno uses the Mikuni and this has the air screw - stock is one & three quarters out. Stock main jet is 150 pilot 30 - We rarely get freezing problems in Canada but the gas at the pump does have methyl hydrate added to avoid this. - I think you have given him the right info re: cleaning the carb etc - check that somebody hasn't leaned out the pilot ( if it runs better with the air screw in it sounds lean) - be careful using any gas line anti-freeze etc - this stuff is bad news for two strokes. Enjoy your trip & Merry Christmas Quote Link to comment Share on other sites More sharing options...
alan bechard Posted December 12, 2005 Author Report Share Posted December 12, 2005 (edited) Thanks Dave, that looks like what I will be doing this Sunday. I figure if he can take care of my daughter for this year, I can take care of his bike for a day! Those baseline #s are great, I really appreciate it.

jtt Posted December 13, 2005 Report Share Posted December 13, 2005 I'd bring along a richer pilot jet or two Alan. Assuming the carb is reasonably clean, having the screw all the way in indicates it's lean, which is also a feature of cold temps (denser air).

ham2 Posted December 13, 2005 Report Share Posted December 13, 2005 I went out last year in Jan/Feb (North of England)in some pretty cold conditions - minus 3 degrees C-and the carb started to ice-up badly. I made a cardboard liner covered in silver duct tape to go around the carb (nothing too elaborate)... really worked. Don't mean to teach my Granny to suck eggs but give it a go -- really cheap option. :hat: Quote Link to comment Share on other sites More sharing options...
telecat Posted December 17, 2005 Report Share Posted December 17, 2005 NYL had this problem on a REV50. We started adding Silkelene FST Pro to the fuel mix and have had no problems since. Quote Link to comment Share on other sites More sharing options...
alan bechard Posted December 18, 2005 Author Report Share Posted December 18, 2005 It looks like it was a clogged pilot jet. It also has a 27.5 pilot in it which looks a touch lean. It is running ok now though. Typing on the German keyboard is a bit different as well, they swapped some of the dang letters around! Anyway, I think we will order a new throttle cable, a 30 pilot, and am about to dig into the rear end and see what I find there. I am having a bit of knock on initial throttle opening, I think I will try bringing in the airscrew a touch, needle is in middle position, may bring it up a notch as well. Not sure if it is the idle circuit or the needle that is the problem, feels about in the middle or transition area so I will fool around with both. Thanks for the help, hopefully we will get this thing sorted and crisp. One of the problems is that I do not think it will ever feel as crisp as my 03 Sherco. I wish I had another to compare what it feels like when it is right. I think I will just get it as crisp as I can until I start to knock. I also am not sure about the octane here, if I remember right, they use a different system than we do to measure it, but really, as long as it is the most expensive, it is probably the best.

ham2 Posted December 24, 2005 Report Share Posted December 24, 2005 Teach my granny to suck eggs It's a common saying round these parts. Just means: I don't mean to tell you something you already know I didn't invent it ...honest! :hat: Quote Link to comment Share on other sites More sharing options...
charliechitlins Posted December 26, 2005 Report Share Posted December 26, 2005 So...we can assume that granny already knows how to suck eggs? Quote Link to comment Share on other sites More sharing options...
feetupfun Posted December 26, 2005 Report Share Posted December 26, 2005 (edited) Grandma sucking eggs refers to the process of emptying chicken eggs via two small holes, one in each end, to preserve the shell in one piece. It is quite a skill to be able to empty the egg without breaking the shell....hence the saying.
