M8 referrs to the diameter of the bolt shank & threads, not the bolt head, so M8= 8mm ( close to 5/16") , M8= 10mm ( between 3/8" and 7/16") . The thread pitch would be designated after that, such as M8-1.25 . an M8x50mm would be 50mm long from the threaded tip, to where the shank ends and meets the hex portion. ( or head, in the case of a socket head cap screw )
As for the motorcycle, don't go too crazy trying for cornering speed, motorcycles are much less forgiving than cars! Be especially carefull in intersections, or at stop streets, they tend to collect sand/oil. It's easy to take a quick trip to the pavement, ask me how I know! I no longer "push it" thru these types of corners, ramps and twisty roads tend to me much cleaner.
Oh yeah, assuming they are blind bolted (without nuts) , you could go crazy and safety-wire them. With nut/bolt assemblies you can use a drilled bolt with castle nuts. I expect the Blue will be fine, as mentioned.
I now reply as an embarrassed and ashamed man. As I have not yet fixed my car. The contributors to the lack of drivability are gluttony, lust, and rain. Only one cause is not a sin, but I feel guilt and frustration, directed from me, to me, for having deprived myself of my number one material affection, my 986. I have no excuse. All weekend last weekend, it was beautiful, bright, and perfect weather to snuggle up under my car and do some work. But it was my Birthday weekend, and I was out riding the motorcycle, practicing and improving, stopping only to buy myself a Birthday present.
Then, when it came time to get to work, I realized I had a whole project to do for my Summer Lit class. I am truly and deeply angry at myself for not fixing the car when I had a better opportunity to do so. Another opportunity had presented itself during the week. Foolish as I am, I spent half the time I had set aside to work on the car trying to find the key for the locking lug nut. By the time I found it (right where I first looked, somehow eluding my gaze), it was too late to get the work done and get to the office.
It has been raining all week, and will rain this weekend, so even with all the tools, I had nowhere to work on the car, as the garage has no light unless a flashlight is used, which is exactly what I have planned. I unpacked another box of stuff today, and found a trio of lights that, when purchasing, seemed useful. After owning them for two years, however, I have not used them once. Now, I will have a use for them. They are small LED work lights, shaped kind of like a sea urchin, only with stubby points, at the end of which, resides a magnet. They are really handy, but I have never needed them. I got them at Radio Shack for this exact purpose, the magnetic flashlight that give light in any direction, they work wonderfully as mini shop lights, for use while under a car, hands free. VERY USEFUL! LINK - http://www.radioshac...oductId=3876590
I also got myself a 12oz can of Electronic Parts Cleaner for the threads on the Differential and the Bolts. I thought this would work best as it is designed to clean, but evaporate quickly and easily so that the metal connections are not damaged. To my knowledge, LocTite creates an Ionic Bond between the metals. This bond is at its' strongest when the metals touch each other cleanly. I am worried it may not be aggressive enough to remove any and all grease in the threads though.
As for the riding, usually I've cleared off the rust (not real rust, metaphoric rust, on my riding skill) after the first week of everyday riding, if it has been over a month off the bike. This proved true this May. I'm enjoying the riding very much, improving in the last month to a comfort level I haven't reached before. But I'm building more than just that, I am also improving. I fell my third day of riding ever, four years ago, and saw my mother fall her first week, as she tried to learn to make my stepfather happy. These two events were far from traumatic, but still made me unsettled on the bike. It is only this May that I feel at home on the bike, which I picked up from commuting on the bike. It set the stage for improvement in riding skill, and this year will hopefully see many motorcycle miles and much improvement.
As far as safety wiring my bolts, I don't know if I fully understand what you mean, but I have used castle nuts before and from that can assume what you mean. I know there are a great many permanent fixes to this problem. Ideally, I want the most durable, but least permanent fix. Something that will not come loose of it's own accord, but will still be removable should that need ever arise. I do want to take the car to a German-Specialist repair shop in the area to check out the whole car, to make sure that everything is A-O.K.
If, after I take the car to a shop, these bolts come loose again, I will either blame the shop, if they do anything to it after I fix it, and then repair it using red LocTite (262). If that fails, I will either take it to a Porsche Dealership and bleed money, or use the most permanent fix I can come up with.
Also, is there an Off Topic Section on these forums? I'd like to talk about the two-wheels in relation to Porsches, as in, what type of people who drive these cars ride what type of bikes. Also, people who ride and drive a Porsche will have a superior understanding of both, compared to people who only ride, only drive, or don't care about motorsport, and the appreciation of the road.
