New Swingarm In Progress

Hey Blaner

The swinger looks good, you did a good job.

When I started building mine I was also thinking of using a vesconite bush instead of a bearing. I decided to stick with the bearings did not want to take a chance. You dont have to buy the bearing from Yamaha you can get it from any bearing supplier plus it will be a lot cheaper. Let me know how the vesconite holds up.

Good job with the thread I like all the detail! I:I

I got the swinger back from the plating guy...looks good for galvanizing!

Here is my theory on chain guide placement..

in here you can see the two main lines that run from right two left (parallel) they represent the top and bottom of the swing arm leg.

then you see the dot marked "bolt" that is the back bottom skid gaurd bolt hole center.

From there I knew the back chain guide bolt center is 165mm. Thus an arc using a compass can be made. so the rear chain guide bolt center lies somewhere on this arc. but where?

I then marked the from skid plate bolt hole center and drew a line between them,
The I measured the old swinger and found that the back chain guide bolt hole was 11mm up from this line joining the skid plate bolt holes, therefore I found where 11mm up from the joining line met the 165 arc and then I had the correct location for the chain guide bolt hole!

again, awesome work blaner,
luvin the galvanizing, keep us posted how it holds up long term !

very nice. makes me want to take mine into work after i finish the shock mount and get it dipped. lead or zinc galv? i also happen to know a place where i could get it dipped in industrial grade fender coating(heavyduty bed liner). im just very undecided. great work thought, very nice finished product. looks strong.

Great thread. Rep given

this is not hot dip galvanizing, it is electroplating galvanizing, it uses an electrolosis process, zinc based and it comes in gold, silver and black.

I did not want the hot dip as it always looks a bit rough and mucky.

borednstreched · Feb 9, 2012

^ ahhh electroplate very very nice, all we have at work is molten dip, and it does leave quite a rough finish like you mentioned.

Got it all assembled tonight, new brake pads ect. Also did a leak test while I was busy and found the spark plug was bubbling, so put some copper slip on and sent it back in...no leaks!

Il get some pics up tomorrow in the light and i really want to take it out for a burn as its my last day before i go back to university

Very nice could pass for chrome! Love the explination of the chain guide bolts I was even able to understand it!!!!

Blaner · Feb 10, 2012

TA-DA! All done ready to roll

Here, I had the guy who did my front bushes make me a plan with the shock mount. I never liked the plain bolt on method as over tightening the bolt could bent or snap the shock ears, so last time I made a metal tube that the bolt went through, that however wore loose and was never a tight fit to start with. It wore the shock hole slightly too. So now I had this guy drill out the shock to 15mm and press fit a brass bush in which the bolt fits snugly though and also snugly through the swinger mount holes. So now, the shock body will not wear anymore, only the brass, and when it does wear, I have a spare to replace it with. Also, the bush prevents over tightening of the bolt and doesnt allow the shock ears to bend!

Grease point.

Then i decided that the only thing missing was MUD

So I went and found some...

And some folaige for extra colour...

littledh173 · Feb 10, 2012

Thats not mud,, maybe driveway spackle!!! Just kidding, nice project and I like the galvanizing.

Great work! How does it ride?

feels good, no problems on the 1 1/2 hr ride i did today, cant say I noticed the extra 15mm length but perhaps il pick that up over time.

StrokedTater244 · Feb 10, 2012

awesome man, looks great! i dont like the pin through the aluminum either, i use some nylon bushings, they hold up well.

Blaner · Feb 10, 2012

ya nylon would work too, but the brass is softer than the alloy so that will wear instead of the alloy, to be honest, i never thought of nylon
