As I've mentioned in another post (http://www.magnaownersoftexas.com/forums/index.php/topic,5473.msg52523.html#msg52523), I've got quite a bit of things that I could do to my Magna so I was wondering if anybody would be willing to host a wrenching session this fall in the DFW area. I do have a place with a garage, but I have no tools, no furniture, no food, etc. Is there anybody else out there who has work to do on their bikes as well?
Brandon, I can always hold one.. Let me know when your available, and I will check my call schedule etc.
Yeah, wrench session!
It's been too long since I've *really* ridden, so I'm making my Magna a priority. I will be purchasing a new front and rear Metzler ME880 this week and will be ready to make a wrenching session some time after the 22nd of October, 2012 (have to wait until I'm not on-call at work). I won't be able to buy any parts to redo the fork seals, but I *will* have tires, brakestay rod, risers and passenger relocation pegs. If I can find it quick and cheap enough, I may also have replacement parts for my broken turn signal switch.

So what about a session on Saturday the 27th of October, or the following Sunday? Other than weekends I can also take a day off from work (I get a free day for being on-call) or scurry down to your place after work.
Tires came in today. Greg, are you still willing to host a wrenching session?
Too bad you didn't have these 2 weeks ago, I put a tire and chain on mine, doing what you needed could have happened that day.
This weekend I am headed to a pie run, after that Talimena Parkway than New Orleans, I am pretty booked for a bit.

Color me green! No, I am not an eco-nut, just envious...

The bike has 21k miles on it now, and I think it had 17k when I bought it. I don't know when or even if my chain has ever been replaced. Isn't my bike at the mileage for when this is normally done? And when chains are replaced, does the sprocket need it as well?
Chain life depends on the driver, maintenance, brand of chain, etc. Most of my chains last 12-14K miles, the one I just changed lasted 23K miles and changed because I ran out of adjustment, normally my chains kink up.
Some change the sprockets and chain at the same time, I don't. Never use to and never started this process, it doesn't hurt. Aluminum sprockets I can see and I do not do that either. Let's say you replace aluminum sprockets each time you replace the chain, steel sprockets being harder it should last longer, yes?
Let's say you buy into the theory (no problem with ones who do this) of replacing steel sprockets each time you replace the chain due to wear, than the counter shaft sprocket should be replaced 2-3 times before you replace the rear as it goes around 2.5 times for every one revolution of the rear sprocket.
I put 66k on a 3rd generation Magna and it had 2k on when I bought it. So, total is 68k and still riding it 30 miles round trip to work 3 times a week. I thought i have to replace it at 30k and then at 40k. I bought the new chain at 50k thinking that I will replace it. But now at 68k I am running out of adjustment so I am planning to replace it at 70k.
Why fix it if it is not broken?

Terry, your reasoning makes sense, except that it much more complicated than it appears. First of all, harder surfaces may not last longer. A classic mistake that newly minted mechanical engineers make when they design their first gear box and discover rapid wear is to fabricate the same gear design with harder metal(s). The new gears wear faster than the first set!! The optimum shape of the gear teeth, allowing a smooth meshing action, extends the life of gears better than any other factor, (given adequate lubrication in all cases). So it is probably also true that the shape of the "valleys" and the teeth has more to do with sprocket life than the hardness of the sprockets. I use steel because it is cheaper. I have no data on relative life of steel and aluminum alloys for sprockets used with roller chain.
I replace sockets when they are clearly worn. Devin replaced both sprockets and a chain one afternoon at my place, so everyone has a different take on it.
My imagination tells me the biggest factor in chain wear is grit. The principal benefit to cleaning is grit removal. Lubrication is important, too, of course, but merely adding more lubricant is not very helpful if you have not cleaned the chain after travelling that caliche or gravel road.
As I pointed out in another post, chains don't stretch, they wear. They get longer because the pins wear against the rollers, on the inside of the rollers. The big culprit for this wear is grit.
So I got the replacement Cycle-istiC brakestay rod from Dobie after he found out that I had the older version, so now I'm ready to replace the tires on my Magna.
Is anybody willing to host a wrenching session, no matter how small? I don't have many tools and *may* not be able to replace these tires on my own. I'm anxious to get this bike mobile again so I can squeeze out as much riding as I can before the ice comes.
yes i am. give me a shout and we well get it arranged

Contacted Greg, wrenching session at his place, November 10th.
So Greg, what's a good time to show up? Is there anybody else planning to go?
This guy would like to join! But I do need directions
It'll be a 3 hour ride from my place
My only real goal is front brake rotor... otherwise I'll be there to ride... and harass y'all :Dj
Scott aka Hop Along
I'll be there at 0900.
I'm on my way too, but I noticed that fuel is leaking from somewhere when I was warming the bike up, so I'll be trailering in.
You all have fun stuck on the boat one day I will see the bank again :( :(
Greg and Christie,
Thanks again for hosting the wrench session, it is appreciated!
And thanks to all the folk for sharing knowledge, expertise... and ideas for making a new end table out of the front rotor we took off :-D
Great day all said and done: pastoral sunrise on the ride down, with sunset orange colors that complement the 'smurf blue' on the ride back up to Norman.
Can't wait for another!!
Hop Along
I'm glad you made it back safely Hop Along. I enjoyed the session. Thanks for hosting Greg and Christie.
Good to see Scott, Brandon and Greg. I was glad to help out for a short period of time before taking my riders out to east Texas.
Thank you very much Queen Christie for the coffee jump start at 0900. It gets me in the right frame of mind for pounding a tire off a rim.
Kristi and I are always happy to see, help, and enjoy the company of MOOT'sters!!!!
I trust Brandon and Jerry got the new brakestays installed?
Brandon did. Jerry did not attend this wrenching, made me sad... ;)
Mine has been replaced. I wanted to be there but had committed to help a sick church member move to a new apartment. Will be at the next one.
Good deal. If anyone happens across a Magna owner with one of our old style 2-piece brakestays, please have them contact us to get it replaced. Thanks, all.

Yes indeed, and now I have a fat rear tire! Can't wait to take it out for a ride.
