  1. Confused with pipe/tube routing

    Dominator / FMX
    Hi Guys, so yesterday I rode the Dominator to work for the first time since the bike has been in bits and put back together. I'm not sure the vacuum pipes etc are correctly configured and wondered if anyone can help. All photos are pre strip down and they themselves may or may not show the...
  2. YACO (Yet another Chain Oiler)

    Bodgers Corner
    I wanted to get rid of the sticky spray lube for the chain and intended to build my own chain oiler.<br> My main objectives were: low tech, independent from motor vacuum or electricity/electronics. full manual control of the amount of oil being applied, depending on road or weather conditions...

  4. Carb balancing gizmo....any thoughts?

    Transalp
    Made a carb sync the other day from a cheapo water level I'd forgotten I owned (:rolleyes:) Anyway, after about twenty minutes of faffing and a some advanced 'zip tie' engineering, my gauge was good to go. Worked a treat, once I was familiar with the sensitivity of the throttle plate screw...
  5. Running rough since rebuild

    Transalp
    Hi I had my first test ride following the rebuild last night and another today. I haven't done anything to the insides of the engine. The only thing I changed was the spark plugs. Admittedly I still haven't managed to get the airbox connectors seated properly on the carbs. However it is...
  6. Black smoke from a 98 Dominator :/

    Dominator / FMX
    Good friends, I have a problem with my 98 dominator. I have tried my best to solve it myself but my mechanic skills are fare from good. When I bought the bike it started pretty well but it looked that the carburetor was clogged with something. In low revs it makes some black smoke and stalls...

  8. Exhaust backfire

    Transalp
    Hola! mY '04 TA backfires and pops when I let off the throttle. Just just started. This winter I rebuilt the vacuum actuated fuel valve and I installed a Scotoiler for the rear chain. Both of these pull vacuum from the nipple on the rear cylinder inlet. The bike never backfired before I...
  9. Anyone know where I can get carbs balanced around Bristol?

    Africa Twin
    Hi all! Would like to get my carbs balanced on my RD07a. Something I would do myself but need the vacuum guages. Can anyone recommend somewhere I could go or does some nice person have a gauge I could borrow? Thanks very much, John

I have striped the engine to do the 279 big bore. then broke my shoulders in a bike accident so have been away from the rebuild for 3 months...

Currently, the bike will have a difficult time cold starting then shoots blue smoke for about 15 seconds then completely clear. it will idle for about 30 seconds then a loud pop comes from the exhaust header and it...
  12. XL650 Valves versus Compression

    Transalp
    Hi all, First post, but having read a lot here I'm sure I'll get some good heads up. Last time my TA had the valves set was by a main dealer at 16000 miles. I'm reasonably sure that at least the rears were done because within a couple of hundred miles I had to get in myself and renew the o seal...
  13. Replace fuel pump with Vacuum Pump

    Africa Twin
    I will be surprised if no one has seen this before but I couldn't find anything on the forum... Anyway, I found this modification video https://www.youtube.com/watch?v=d3Pv0ZORwn0 Its a guy who replaced his OE fuel pump with a vacuum pump connected to the little vacuum port normally used for...
  14. Drip from fuel tap after engine shut off.

    Transalp
    Hi folks, I've just replaced carb float chamber gaskets and diaphragms on my 1989 TA. Bike now runs great. However just as I was about to fit the fairings back on I noticed fuel dripping from the fuel tap. I checked all screws etc and all were fine. I refitted the 2 hoses from the tap that I...

  16. Please school me on RD03 carbs

    Africa Twin
    The carbs are now out of the carbs. They will be degreased, cleaned up, covers will be zinc plated, and carbs will be rebuilt. I popped the covers and found the rubber diaphragms to be ain good shape. No tear or crack. Nonetheless, I wonder what's the purpose of the pistons and diaphragm. What...
  17. Dynojet

    Africa Twin
    Hi folks, just bought an XRV, 1999. Just stripped the carbs to review and clean. Noticed that was running with larger jets etc seem to recall 124 for mains. Reviewing the Dynojet instructions from web page they recommend drilling out the vacuum slide. Both outer slide holes need expanding, but...
  18. Fuel tap question

    Transalp
    On my XL600VV there is 2 vacuum pipe attachments on the fuel tap. The one forward to the front wheel is the correct one to attach the vacuum pipe to, correct? If so, is the other one left open? Looks strange and there is a hissing coming from it when it is ticking over.. Seems not correct...
  19. Carb rebuild service in UK? Trying to resurect TA after 5 years standing.

    Transalp
    Hi, I've got a 650xl which has been standing for around 5 years and I'm trying to get it running. It's done less then 3,000 miles from new. It would not start. I tried to drain the carbs. Green goo came out, so I removed the carbs and sprayed carb cleaner in everywhere I could until all ran...
  20. Carb balancing D.I.Y

    Transalp
    Hi Folks, thought I'd have a crack at do it yourself carb balancing today. Got my plastic hose and half filled liquid containers, connected it all up onto the vacuum connectors on each cylinder and fired it up. The adjustment is through the hole in the airbox as you're all probably aware ( not...
