  1. You basically say you have some problems and have done stuff. When you tested the charging voltage, what were the numbers? £k revs, 6k revs lights on or off. What did you do to check the draw, in line meter? There is normally something leaking current, nothing is perfect on a 60k bike. Ultimately your first suspect will ALWAYS be the rec unit on a 600 yam.
  2. Wont help, the ally of the engine absorbs the heat. unless you really heat it with mixed gas or some such. You should try a proper penetrating oil, even diesel is better than wd40. I have had some luck in the past with the torque setting on my drill in the past, setting it to the max torque and letting the drill rattle like its fully tightened it but not. Bit like a rattle gun, even better if you can borrow or steal one of those. (I have the socket adapters so I can use sockets on my drill). The vibrations and the twisting action seem to work sometimes.
  3. Go back to the carbs, if 'start ya bastard' gets it going you got/there is something wrong in the choke/idle circuit.
  4. Sounds like you need to keep a decent distance behind you too.
  5. Same with all security you cannot ever completely prevent something being stolen, you just make it harder to steal than somebody elses. Sad world we live in. The scumbags view of 'its insured'. I hate it but we only have one world.

    TPMS is just another thing to go wrong, in Wales I had my temp shoot up. What went through my mind, water pump? Seal? Shaft? Hose? . ? The sender broke.. My Dad was a mechanic all his working life and called shit like this 'panic gauges'. Yes 1% people might get a benefit, chances are many more will be cursing weird tyre problems that aren't there.
  7. Sometimes on todays really complex motorcycles you have moments like this where the fuel temperature sender says the fuel has suddenly dropped 20 degrees but the bike is hot and the brain has a bit of a 'huh?' When you pushed it away and then started it things had most likely come back 'within normal operating limits'. Or it compensated somehow.
  8. No guarantees as its a mongrel, you will need to connect and see what happens with the tail light, I would expect the yellow to be the brake light personally, on my dt the tail light feed is blue with the earth being black. As for the indicators brown is right, green is left. Pretty much all yams have it that way.
  9. That sounds to me like you seized it from oil starvation. The ticking is most likely the remnants of the rings, could also be dry valve gear. I would not hold much hope for anything above gearbox level being any good. The valve gear floats on an oil film so the cam dies first taking the head with them. (likely the noise) the piston and rings will be toasted as that will have been the seizure when the piston heats up and swells in the bore stopping it (lunching the rings normally). When it cools down it will generally restart but wounded and limping. Not good, important point is.. ANY good bike mech with the parts to hand can re do that top end in a couple of hours tops. Any good mech will not talk about carbs and timing either with this that's just pub mechanics. Simple fact, an engine without oil, will die.
  10. Honestly if its a mint 1983 lc leave well alone. just enjoy it.

    Wet clutch so shake any ideas of using your car oil. Get some proper motorcycle oil, synthetic or otherwise doesent really matter in something like a dt box, its just a basic oil bath in truth. No point spanking money on expensive oils. that gearbox is that strong it could probably run happily in old chip fat. You don't want to use car oil as that has components to reduce friction which can weaken your clutch.
  12. Well, home showered and with a brew. Bloody good weekend. Fuelled up 7 times, 49litres in all, actually works out at 48 to the gallon over the 540miles I did. Refuelling at 75 miles seemed to be the best, Some great roads and some amazing places. God knows how stuff gets delivered to some of those people. Only pain for me was thinking I would kill the current chain with this trip, bad move, set up a high frequency vibe that lost me several nuts and bolts over the weekend. Had to remove the other heat shield before I got home I think my hands will be numb till august, where next? We should make it more than once a year too. Oh, and all the rain we were worried about over the weekend, I think I got it all from just past Broadway for 90% of the trip home it absolutely fct it down. Other times just heavy, lol.
  13. Here fine. Bike had a moan on the way but it was my fault. Beautiful campsite. Catching some rays as I wait for everyone. Yep in Wales and it's cracking the flags. Bonus, cos we're all in widdle one man jobbies (or as good as) it's only 11 quid a pop. Not 17.
  14. Smashin. Stopped in Malvern for fuel and a brew atm. Eta 5 ish I suppose.
  15. I was right though.... :)
