    Tserts I'm glad to help if you need further info.

    Regarding the fuel supply with tank off, it's as easy at to get your self some extra fuel tube of suitable length and an empty bic pen body. Then, just put your fuel tank on top of the workbench or similar, attach the empty pen body to the fuel tube going to the fuel filter, then the other end of the pen to your extra fuel tube and finally from the end of the extra fuel tube to the tanks fuel tap. Just position the fuel tank on top of the workbench with enough clearance at the bottom...

    On a different but also very annoying note, I am at the middle of a maintenance service with my AT and I need to check valve clearances.
    Thing is I cannot take the crankshaft cap out no matter how hard I try. I actually fuc*ed up the cap's hexagonal insert for the 10mm hex L key... now, what? I already see myself having to order a new ACG cover. Damn! :eek1

    Here's the damage:

    I don't know whether any previous owner just tightened the damn cap too tight or even put some sort of glue to its threads but on the last 2 valve checkings the crankshaft was turned by shifting into 5th gear and turning the rear wheel up to the right spot... I reckon I could have gone down the same road this time, but what the heck I just wanted to do it by the book and remove the cap... double-damn!!! :eek1

    I've had reasonably good luck with stripped allen bolts in soft material like this by gently tapping in a TORX bit of the appropriate size. This size is determined by just how badly the inside is stripped.

    Then add a bit of heat with a heat gun or propane torch.

    But be careful. If you hit it too hard, the case CAN crack....and then your language will become even more interesting.


    If it's any consolation, this is a common problem with Transalps and ATs. Someone (in the US I think) sells a replacement plug with a protruding hex head.

    I put some motor oil on the threads (careful with anitseize etc since the inside of this plug is exposed to the oil and any compound you use will find it's way into the engine's oil supply), then use a new O-ring and do NOT tighten the plug more than "spark plug- tight"

    Yeah, please excuse "my french"... I've already ordered a new cap and O-ring, now I just need to get the old cap out. Good idea on the torx bit!!!

    If the torx makes a worse mess and fails to unscrew the cap, my next step would be to dremel a flathead screwdriver slot. It won't be pretty, but it might get the bolt out... Get the engine warm in order to use metal expansion to your advantage, if you don't have a torch...

    Best of luck!

    I've had luck striking it with a sharp cold chisel and hammer from the right angle...yeah just smack it! :D

    As suggested already putting a heat gun on it will help.

    IMO alot of these plugs get stripped because the owners hex bit tool (either the 10mm or 6mm) are just plain worn out. Even some new ones fit sloppy. Find the tightest fitting one in your tool box or go buy a new one if need be.

    Most recently I removed the ones off my TA with an electric impact gun.

    That's cheating and you know it.. We're not supposed to use torque wrenches, specialty and power tools either...

    You can take a bolt with a little larger head than the hole and grind and/or file it to fit the allen hole. Then use vice grips on the shank to turn the newly made allen wrench. Gently tap on the end of the bolt while turning will sometimes help hold the tool (bolt head) in the hole and shake/vibrate the plug loose. Works in an emergency when you don't have the correct size wrench also. Use some valve grinding compound on the bolt head to help it grab the soft alloy.

    A bit scary.....since you asked.

    At the very least, I'd advise having a helper around to keep their eye on the level and make certain that it doesn't spill onto the exhaust.

    You're doing electrical diagnostics and have the possibility of creating a spark at some point.

    I think you'd be better off with a few feet of extra fuel line run to the actual fuel tank that you can set on a stand or shelf of some sort.

    Keeps the vapors away from your working area.

    In my carrer as a fireman, I've seen many many people get too familiar with gasoline and underestimate it's potential for disaster.

    OH MY, Ladder 's being kind. That's a potential disaster ready to happen. Please use a tank of some type; lawn mower, boat, bike, etc. And outside with some help and a water hose or extinguisher handy.

    does this look safe enough? I can ride for about 6 miles on Elmer. I installed a O ring on the cap and it has worked for years.

    Ok got it, I'll go get about a meter or two of fuel hose and take it from there. This is outside by the way, so i'm not gonna get high at the very least...

    Not to worried about that. I had a neighbor who got a little careless in his garage with gasoline....when he woke up, he was laying flat on this back out on the driveway with his garage on fire. :eek1

    Gooday all, I'm back...

    So I want to test the coils, I have verified that when the problem starts one cylinder quits, add to this the fact that the pulse generator gave the correct readings, and that cooling that part of the engine failed to restore operation, makes me turn my attention to the final leg of ignition: Coils, spark plug wires and sparks.

    So, for the coils, do I check the input voltage, as mentioned in the pages Abilio posted? But that wouldn't test the performance of the coil...

    And another question, is it safe to pull the spark pipes while the engine is running, so as to speed up testing, ir is it better to turn off, unplug, turn back on etc?

    Can you change position of the ignition coils to see if the problem follows one particular coil?

    On another note, I managed to take the cap out! Used a chisel and hammer. Enough of being gentle, some girls just like it rough :evil
    :D

    3 or 4 hits later and the little bastard was out!!! Too bad I learnt about the Limacap too late, as I had already ordered a new original cap...

    Anyway, here's the old cap...

    Thanks to all :norton

    Hi.

    Any one that knows where I can buy a new cockpit for my RD07? My old one dos not work anymore after I had a crash.

    I've seen one on eBay, but 290€ are allot of money for a used one. Are there any alternative that could do the same as the original?
