    I ordered a Hot rod because there is a copper/bronze bushing at the rod end...Also I just repaired one engine with a Prox connecting rod and the lower end bearing was seized, the cause was probably not the rod itself but when the Honda guy's rebuild the engine sometimes ago, they forgot to install the big washer on the crankshaft left bearing, instead they installed it behind the flywheel outside of the crankcase...not a good idea....:norton

    I thinl that the big washer keeps the oil trapped against the left bearing ...but not 100% sure about this.

    Hey guys,

    Just a quick update re. the work to fix my sunken valve seats etc. The garage called me today and it turns out the head is cracked between the valve seat and the spark plug :becca

    They are going to weld the head (apparently it will be like new) and replace all the valves and guides plus a new cam chain rings etc and gaskets and a few other parts i needed to rebuild it, total cost is expected to be around £800 for everything :cry

    On the upside at least the barrel just needed a hone and new rings :D

    It is a lot of cash, but, I'm just thinking that at least I'll know that everything is sorted on it then and fingers crossed once It's fixed it shouldn't need to be done again....

    I still have a oil leak. Looks like the stator gasket. New gasket, in fact second new gasket. I am thinking a little sealant to stick it together better? Anyone see any reason why not. New Ricky stator in there so I shouldn't have to take it off again soon.

    G'day Chris,
    I used an aviation grade sealant on both sides of the gasket when I did my stator..hasn't leaked since.

    Honnestly, the crack thing is usually something superficial, now regarding the guides and valves, I'm surprised that the valves need to be replaced as most of the time a valve grinding/resurfacing is enough and much les expensive, if they replace the guides a resurfacing of the valve seats is mandatory.

    It's the grommet where the wires pass through the cover. Goop on some sealant after you clean it really well and you should be good to go.

    Cheers guys, glad to know I'm not the only crack head here :D

    Edouard, I know what you mean, it is perhaps a little overkill, although, the valves were pretty burnt up... they will be resurfacing etc..and I'm quite safe in the knowledge that it will all be done properly. I'm thinking that it's a lot to shell out, but, I'll know that the top end is all perfect then as future reliability is what I'm after and already starting to plan a shoestring budget ride to Morocco :D

    My next plan is to get an Oil temp dipstick and fit an oil cooler and fan to try and avoid any future damage through over heating etc. I was thinking that I may be able to find one from a pit bike that would fit nicely.

    My plan is to add it to mount it to the front forks under the headlight shroud like the dakar bikes did and fit a stone grill.

    I'll keep you all posted on this, as will be saving pennies first :wink:

    My uncle repaired that leak for me last month with a cereal box and gasket goop.

    he had me take the alternator cover off, then he took engine enamel and sprayed the mating surface on the cover, then pressed a cereal box against it and it traced a perfect gasket on the box. 10 minutes later with a fresh exacto blade and I had a Kellog's gasket :D

    Definitely use the goop, just be careful not to get it in the oil gallery for the clutch rod. I torqued them to 10ftlbs. no leaks from it in the last month or so i've been running it.

    I ran my bike HARD offroad with 15W50 Pennzoil in the summer months with ambient tempurates as high as 116F. I've never had a problem with overheating

    If it was to break down on me, it woulda been this day. Bald tires at the dunes, I was in third gear constantly keeping revs up for about 3 hours, I pulled spark plug the next day it, was a still perfect.

    God my bike looks so different now i need some updated pics

    I've had my 1987 XL600 almost a year now and noticed the bike needs a new chain guide, the one on the front part of the swingarm. The dealer item is over $100 and I would prefer to find something cheaper. The guide on the bike is not like the stock one the dealer can order but I can't find anything like it online and the old one has no brand or numbers. Is there a cheaper guide from a different model that fits ? Can anyone find the material to make one themselves ? I just one something to protect the swingarm from the chain but not pay any more money than I need to pay. Thank you for any leads. I am fairly new to the XL600 bikes.

    You can install a thin block of nylon material on the top of the swingarm where it rubs the most. The botttom I would not worry too much about as it rarely makes contact there. The hard part about doing this is that you have to mill or dremel out the area where the gusset on the swingarm is. This is the welded part that connects both halves of the swingarm and sticks up from the half of the swingarm that the chain sits on. I dremeled it close enough and filled in the difference with silicone once I got the screw holes in the right locations. Come to think of it, you could probably get away with a good amount of silicone after getting the screw hole locations drilled out. I did this and used oil-impregnated nylon from mcmaster-carr. well, that's what I used on the bottom chain rubbing bloock thingy. i did have the "Nyl-oil" nylon ready for the top slider ready to go but stayed with the original white nylon I until I changed to an XR600 swingarm. So, in summary, if you don't want to buy the expensive parts, you can make your own, and it can be in such a way that it is better than stock.

    So I ride to work this morning. BRRR. Got the grips on high. I pull into the shop and I smell hot electrical. I assume it is the electric motor shop across the street burning wire again. RIde home tonight and BRRRRRRRRRR.:D Pull it in the carport and same smell. :eek1 I don't see any smoke. Just smells hot. Can't see where it is coming from. I did not get this smell before the new stator. I also did not need the grips to be on high cause it wasn't 33 degrees out.:rofl Thank goodness it is a short ride to work.:rofl I was sniffing around for the source of the stink. Smells the worst around the controller for the grips. BIke Master grips is what they are. Anyone have this same smelly problem with their grips when the are new?

    They are all over Ebay for $40 to $50. Sometimes you even have a choice of colors!

    I just got my valves re-surfaced. I asked the guy who did it for me, a friend, how much material he took off, and whether he thought it would be worth adding an extra shim under the springs to make up for it. He said he took off very little material and didn't think it would be necessary.

    But now I wanna ask this group. What do y'all think? There are washers/shims in there already which measure about 1mm thick, or about .039". I read in someone's post on here somewhere that they assembled their engine with additional .040" shims just for a little performance enhancement from increased spring tension. It wouldn't be too hard for me to make some thicker shims.

    Opinions?

    Thanks,
    Christian

    Your wasting your time thinking about shimming the valve springs. If anything your friend only KISSED the valve to clean it up. Not like he's taking MM's off of it.

    are the springs progressive? i doubt it so you don't increase tension as they depress. ideally you shim them the same amount as the seats/valves were ground.i wouldn't want anymore tension than needed to alleviate wear on the valve train. personally i would leave them alone.
