  1. Not an expert but the ignitions of today are pretty reliable. Seems to me if it is the ignition it would just not run. If it is running rough and will idle can you pull a plug wire one at a time to see if you can determine which cylinder has the miss? You said your bike was down. How long? Did gas go bad? Any rust in tank? Any inline filters to check or change? Sediment in carbs? Usually whatever I think it might be it is usually the oppisite. So check the Ignition Nor Cal Ed
  2. If someone responds to your topic what is the best way to get back in touch with them? I have responded via replys and have had mixed results. If you put someone on your friends list do they get an e-mail or some other kind of notice without them having to return to the forum and topic they replied to ? If so how do you put someone on your friends list? Thanks to all. Ed
  3. Hey little dave, found this post in the bar and it said it was moved and now im here in the workshop so i have not read any posts pertaining to your question but here is my opinion. Air cooled two strokes rely on getting the heat they generate away from itself via the cooling fins. I have ridden alot in the Glamis sand dunes on a YZ 465 years ago during the summer months and when its hot outside and you are running it hard, and in the sand dunes with a 14 cup paddle tire you have to stay on the pipe even down hill, you start to hear and feel it bog. What is happening is the piston is expanding from heat so is the cylinder and they are starting to seize. Time to stop and let it cool down. good practice to let it cool down before you get to that point but if you dont know where that point pay attention to your bike and if you start to feel power loss at all pull over and shade up for awhile and enjoy the sights. Real critical to two strokes is their pre mix or oil injection oil. Use a good quality oil this will help protect the top and bottom end from heat. Yamaha has good stuff, back in the day we liked Bel-ray blue. But good oil wont fix stupid. I seized a 125 one time and got lucky. I took the head off and gently used a raw hide mallet to knock the piston loose, after it was stone cold of course, squirted a little injector oil on the top of the piston and exercised the piston up and down a bit feeling for any galling (roughness) making sure the cylinder didnt move up or down, put the head back on and fired it back up. Got lucky. As far as your heat tape is concerned the exhaust wrap is designed for four stroke engines. The idea is that the heat in the exhaust coupled with a tuned headder, four or? equal length tubes coming together in a collector, on a natually aspirated engine, carburated, is supposed to help with the scavenging affect created by individual pulses from each cylinder which cause this syphinning action through the cylinder while the exhaust and intake valve are both open on the intake stroke pulling the inert gases, already burnt, form the cylinder and pulling a full charge of fuel/air into the cylinder before the exhaust valve closes. A two stroke exhaust creates a prescribed amount back pressure which regulates the fuel/air mixture in the cylinder since the two stroke does not have valves. They used to call them expansion chambers. The exhaust would go from the headder pipe to the expansion chamber and create pull affect to a constriction sort of creating a pumping action pulling new charges into the cylinder/bottom end but keeping the charge put by the constriction. adding heat tape would not be recommended. A heat shield would be more appropriate. You want to get heat away from the engine and exhaust not contain it. Besides air circulating around a heat shield will remove heat faster than insulating it with the tape. Remember I said this is my opinion and I will stand corrected by anyone with a better understanding than I have. I am not above learning and welcome any corrective criticisms. Hope this helps a little Little Dave. Also I responded to your offer for help. I would like the phone number to the cycle salvage place you mentioned. And if anyone can help me out my first post to this club is in the Bar titled," yank needs help from across the pond" from Nor Cal Ed Ed
