  1. No , I'm good on theory , I was just wondering.

    W/O2 sensor computer systems on automotive vehicles the engine coolant sensor decides when to go into closed loop and (in theory) the O2 sensor is hot enough to start determining the oxygen content of the exhaust gases. These sensors started out w/one wire , then a second wire was added to have an absolutely good ground for better reading . Then came the four wire system for the addition of a heating element to heat up the sensor for a faster closed loop engagement .

     All other (early style) w/o any oxygen sensors were "closed / open loop" from beginning to end . I don't care too much for this but it was less complicated to engineer/fabricate . Being in the nascent stages , everything is simpler.

  2. I hate to show my ignorance but , do these bikes have an open loop / closed loop built into the computer system w/the O2 sensor style system ? 

    On automobiles the ECM goes into closed loop when the engine is up to operating temp and the O2 sensor is hot enough to  start "working".  

    I assume the non-O2 sensor bikes are programmed to run as is throughout  the temp (cold to hot) temp range?

  3. I don't think the filter or anything else in line could be causing a problem . Do install a new filter when you install a new pump. While you are at it replace all high pressure rubber fuel lines in this circuit. When you tighten the hose clamps on these lines , just get them snug and make suer the clamps are indexed so you can retighten them if necessary .

     Fuel leaking from the pump means the pump is bad .

  4. I measured a fork tube similar to yours and the lower portion (chrome lower) of the fork tube measures 43ish mm 

    The forks on my red frame and black frame measure 40ish mm.  

    You will soon realize there are no absolutes when it comes to these bikes, I found this out a long time ago when I was resealing and rebushing the forks on my 2003ish V11. Got all my stuff from Joe Eish and got everything apart to find out nothing worked. He graciously took all the wrong parts back and sent me the correct stuff.  S.N.s date of production and models mean nothing here. 

     With that being said , someone may have crafted a new (different)front end on this bike , who knows?

  5. 12 hours ago, LaGrasta said:

    Many OEM hoses I found listed, weren't actually available. I agree though, if I could have purchased the OEM one, I would have. At the time, I think the only place that had it was in Germany and it was like $80 plus shipping.

     

    Interesting enough, I only paid $18, and free shipping. I see now, it cost twice that amount!

    That hose is for coolant and it MIGHT not be compatible with petroleum . This may not last as long as you would want. 

  6. You may as well buy two of these hoses , one to install and one to keep around for a spare . When you install this be sure to index the hose clamps so when you do it AGAIN and AGAIN you will have less trouble with R & R . BTW , if you go with the homemade design , keep in mind this will have to be compatible with petroleum . You may spend more time with your innovation than buying an OEM part. Don't feel like the Lone Ranger , we all have a breather tube that did/does look like this .
