  1. This is copied from the Vintage race list Marc I spent some time over the last couple of days looking at the fuel line dry-break quick disconnect couplers I've got, and I thought I would share my findings. It appears these couplings (as commonly sold by various aftermarket motorcycle places) are made by: http://www.colder.com http://www.colder.com/asp_main/GeneralPurp...asticProducts.a sp http://www.colder.com/asp_main/FeaturesBenefits/PLCFBInd.asp These are CPC's PLC series, made of acetal. The PLC series is good for -40->180F and 120 psi of vacuum. According to their product info, acetal is "excellent" for unleaded gasoline and also seems excellent for acetone, benzene, ethanol, and methanol, so maybe we can use it on our fuel drag bikes. I note that some of the packages on the couplers are marked "viton" and others aren't. The standard o-ring is Buna-N so they may have supplied those in the earlier days and then wised up to the fact that the Buna-N didn't hold up that well. I know I've had several O-rings swell up to the point where they tore when I pushed the coupler back together. They do have metal couplers (aluminum and chrome-plated brass - might be a bling bling auto/motorcycle market for those) as well as multiple line couplers and other whizzo things. Replacement O-rings are offered for 80 cents each by the motorcycle places which seemed a bit high so I pulled some of the O-rings off and measured them. It appears the 1/4" connector uses a #008 O-ring and the 5/16" appears to use a #011 ring. A bag of 100 #008 Viton O-rings (5/16" OD x 1/16" stock) from MSC (09265083) is $8.36 A bag of 100 #011 Viton O-rings (7/16" OD x 1/16" stock) from MSC (09265117) is $10.24. MSC has four pages (4196 seems to be for this line) of CPC products and you have to order either side seperately: 1/4 hose barb body $8.22, insert: shutoff $8.07, straight through $1.73 5/16 hose barb body $8.22, insert: shutoff $8.07, straight through $1.77 Chrome-plated brass are roughly $22, $14, and $6.36 There are right-angle inserts too, as well as couplers with NPT threads An aftermarket place sells the single sided 5/16 for $16.95 and the double 5/16 for $21.50 $5-6 savings per coupler would add up pretty quick, and certainly pays for the bag of spare o-rings (since they'd come with Buna-N it might be best to just swap them out right at the start). I feel like this was actually a productive way to spend an hour or so this morning. cheers, Michael
  2. Thanks for the reassurance!! It?s leaking at the lower compression fitting on the right side as sitting on the bike. The reason for the delay in getting the hose, apparently the factory is shut down for a month to upgrade their computer system. Marc
  3. One of the oil lines is leaking and I can't get a replacement line for awhile, the local hydraulic shop has the parts to connect to the pan, but not the large banjo on the cooler, I can make a line that bypasses the cooler and can't think of a reason this would be a problem until I get the line, the average temp is around 55 degrees. Am I missing something? Thanks Marc
  4. I swapped the relays around and the bike starts consistantly now.. What I'd like to know which relay is which, I couldn't find any info in my manual or repair book. Thanks For all the Info!!! Marc
  5. The fuel pump sounds consistant I have the grey bosch relays, I'll try swapping them around. Thanks Marc
  6. The Bike is a 2000 V11 Sport In the last week the bike has a very hard time starting about 50% of the time After it starts the bike runs great. It’s very random, Sometimes first starting in the morning, Sometimes after a long ride and every thing in between, It seems like it's not getting fuel, i'm not really up to speed on fuel injection, but perhaps it's taking to long to build pressure in the system??? Thanks Marc
  7. Thanks for all the info & links, lots to research and read Marc
  8. The bike has the Marazocchi with no preload adjustment. Currently there is way to much movement on the bike, I have the compression dampning one click away from full. and the rebound around 3/4 Is there a recommended sring for these forks or is it a matter of shimming. Thanks Marc
