    tires on my 1987 se lemans V

    FWIW I use Metzler Lasertecs 100/90 front and 120/90 rear. I find them very predicatable and stable on our coarse chip roads here in NZ. A smooth patch of seal here is where the trucks have pushed the chip away on hot days. They get plenty of scratching around corners and have yet to fail...

    Broken auto tensioner spring and Aussie hearts

    Interesting experiment to leave out the spring. Mine did that without me asking! I know the noises youre hearing. I wondered whether a block, approprioately shaped and fashioned to fit between the tensioner blade and the cases would do the trick. maybe alloy or teflon or other nylon. It...

    Copper Gasket Sources

    Hi there Exh to piston = .100" Int/piston = .080 The piston is not evenly gapped to the head. I had the pistons made according to the stock head dimensions and then had the heads made... I am in the works with J&E for pistons based upon the latest head characteristics. Wait until youve...

    Copper Gasket Sources

    Cool photo.:) From hazy memory the groove is set back from the bore and in a place that allows it decent contact with the copper gasket. If the groove is .035 wide and deep, that gives an interference fit to tap the wire into the groove, and approx .012 proud above the deck to be squeezed into...

    Broken auto tensioner spring and Aussie hearts

    I'm glad you noticed this. THis was my first suspect. The other scenario that occurred to me was using a metal blade to work it in around this bump may have scratched the spring and created a stress riser to eventually crack through. This time I took more care and assembled it without using...

    Copper Gasket Sources

    Great info re copper gaskets and annealing. Note the Copper Coat spray recommended. What did you think of the o-ringed barrels wire dimensions? Got them straight from VHR when I ordered my parts in the early 80's (thats BC...before children) What did you think of the piston profile from...

    Broken auto tensioner spring and Aussie hearts

    Just completeda 100km run around our East Cape. Ran beautifully, wether terrific, more curves than you can poke a sharp stick at, and a quiet timing chain. Does it get any better? Cheers Andy in NZ:P

    Copper Gasket Sources

    Just found some details. Vance and Hines used to recommend (back in the day) a small groove.035" into the liner to hold a .047" OD copper wire tapped in place. When my lners were being bored, we made up a tool to machine the groove . Take care to taper the ends and not butt fit them. Allow for...

    Copper Gasket Sources

    re. copper, I've seen web sites that say don't anneal. We'll see what the manuf. of the gaskets I've ordered suggests. The wire is suggested by most makers too. I'll see what I get and go from there. One suggestion was that the depth of groove should allow no more than 20% of wire "showing" for...

    Broken auto tensioner spring and Aussie hearts

    Cheers Pete My spring broke at the casting boss, I wonder if it fretted against the boss? I was as careful as possible when I installed it and used the same method you have described. The plot thickens... Andy in NZ:huh:

    Copper Gasket Sources

    I had a local gasket maker here in NZ cut out 2 different copper head gaskets for a GS1100 I was racing. The 2 thicknesses allowed some variation in compression ratio. I also had the barrells o-ringed (a must for high compression approx 16:1 on alcohol). I recommend this process for any high...

    Broken auto tensioner spring and Aussie hearts

    Greetings all I thought that after beating the Aussies in the Rugby League World Cup final (ours for 4 years!!!) nothing could spoli my day, until I drained the oil on the LM V. What did I find...the hook end off a very thin spring. It didnt take long to work out it was from the auto...
