  1. Sounds like your problem is one of three things. Cam and crank center lines are now further apart (thicker head gasket), shorter cam chain, or tensioner not backing off far enough. How much thicker is the head gasket, same number of links in the new chain, chain pitch and length off (hard to tell on this one due to wear on old chain) , are both adjusters backed off.....? Hang in there...........you'll get it! Old School Al
  2. Strange...........my 200's and 100 run better with the stock jets! Old School Al
  3. Most likely you've never changed one it sounds like...........not a part you just install to see what happens, or at every point change. Not trying to give you a bad time..........just saying it how it is. Take notice of how most motorcycles still have the original condenser..........(and how easy it is to tell if they have been changed). For those that are unaware, many motorcycle condensers have the wires soldered to them (no connectors). Some are mounted on the coil and some are mounted on the stator. Not like the old Chevy to change at all....! Not something you change every time you replace points as is common in automotive. These are high quality condensers and rarely give problems. Very seldom will you see a old motorcycle that they have been changed on...........and if they have it's usually a blotched up soldering mess. While they can be changed when one fails, it requires above average skills to do a nice clean reliable job. Often another stator or coil is needed after a blotched up solder job. Make sure the condenser is bad before you replace it ............ and make sure whoever is replacing it knows their way around with soldering wires! Old School Al
  4. Have you ever actually changed a condenser on one of these...........any idea at all what is involved? Ever seen the mess that is most often made.............? Better rule out everything else...........then isolate and test. If bad.....then and only then replace!!!
  5. Are you aware of what is involved in changing many of these condensers? And next question.........what exactly is gained by changing them? Old School Al
  6. Even more important.............how did you clean the points? The contacts need to be perfect to function............the single most overlooked problem on these ignition systems. Second problem was improper adjustment method. Condensers are not replaced unless there is a point life problem or they fail............and they very rarely do. This applies to most of the older models right on up to the four cyls.. Old School Al
  7. What's your engine number............? Old School Al
  8. And ................when boring you want to center on the outside of the sleeve instead of the inside to center the bore in the sleeve. Many times this isn't done resulting a thin side and a thick side .......... and guess what happens on the thin side! Old School Al
  9. I thought I was the only one on the planet that knew all that. It's great to know someone else understands this to. Thanks When using Octane Booster the spark arrestor is no longer effective due to the vacuum caused by the speed of the motorcycle actually sucking the carbon particles out the exhaust pipe!

  10. Are you sure you don't have a problem with the compression tester...........are you holding the throttle wide open when testing? If it has enough compression to start I wouldn't worry too much about testing compression. Take it for a ride and get it warmed up real good and see what it does. See how it runs, is it smoking, how does it start hot.........? If everything checks out okay the next test would be with some miles how much oil does it use ( if it's not smoking probably not much). Get it warmed up good and you'll know more about where you're at. Old School Al
  11. It shows 84-85 XR200R after draining only, at 355cc (12.0 oz). For 86-90 it shows 350cc (12.0 oz) and also gives a specified level of 150mm (5.9 in.). Old School Al
  12. Out of my Honda Service Specifications Manual 1959 - 1980, XR80 forks........... To fill dry fork assembly 115 - 120cc (3.9 - 4.1 oz) To refill after draining 105 - 110cc (3.5 - 3.7 oz) Old School Al
  13. Checking compression with oil won't work if the intake valve is not closed.................needs to be adjusted before doing test. You say the air filter was dirty and you replaced it with a new one..............was it damaged, did it let dirt get by? Also, when you adjust the valves is the time to install the decomp cable, as it needs to be adjusted to at TDC on compression to work properly. Your service manual will cover this. Old School Al
  14. Update ................? Old School Al
  15. Octane Arthur..................you have perfected the most important qualification to become a politician! Old School Al
