motors

[pggg]

Well check this out - there's not much to an XS11 motor and it's nice and simple. I've just thrown every bolt and nut in one container. Someone wanted the conrod length once, so there they are. The alternater is so bloody heavy I'm picking if you dumped it you'd get heaps more acceleration.

"Lawn and Yawn"

I didn't see any 'Doggie Landmines' in the pic. It's not a mechanics back yard without them.

Hey pggg,

do you guys down there have all the LETHAL creepy/crawly things they have in Australia???

Wouldn't like to find em taking up residence in the bike

Actually I was just checking out the engine cases from the inside, as I'm gonna hack at my chaindrive engine cases to fit a 14 tooth sprocket. Looks like it can be done No dog landmines in that jungle John - the occasional volley fired from a slug gun out the window puts paid to that. Dogs don't dare come round here Luckily there's no snakes or poison crawlies in NZ mro, the Aussies kindly look after them for us

Sponge Bob

John...
These great Northwest winters, nothing but rain. By the time I finally get a 'dry' day to clean up after the dogs, I'm using a sponge instead of my summer shovel.

.. do you have any idea's on what you will use to cover the hole (seal the case)you will make to clear the sprocket and chain

[pggg]

case is 5mm thick - needs 3mm skimmed off the outside. Only a small area. I'll get back to you about the hole if I f*#* it up.

Is it possible for you to measure the center to center length of one of the connecting rod's?One cannot do it from a picture but must have a rod in his possession out of a motor as you do too properly measure it.The length would be from the center of the wrist pin hole, to the center of the crank pin/rod bearing hole.The crank in one of these thing's is what's heavy and in retrospect I wish I had did some work on the counter weight's when I had mine apart but that would have required that the recip assembly be rebalanced which I did not want to have to do.It's true the alternator is a heavy muther and drag bike's don't use them but in my case I need something to create that juice to light the fire.There is another alternative to this alternator problem,but at least in my case the end would not justify the mean's.Thank's for any help you can give me on this rod question.Dan

Here we go Dan, it's 125mm centre to centre. Yep, an XS11 crank would be good for bludgeoning elephants, dinosaurs etc...

Thank you so very much for doing this for me.This mean's the Eleven has a rod ratio of 1.82 to 1,very good and standard practice on Hemi head motor's of that era.The rod's and crank are very beefy and subsquently can be lightened a bunch without hurting their reliability.I am thinking about building a stroker motor by having the crank pin's welded and off set ground for a 6 mm stroke increase.Venolia piston's in California can make a set of piston's with a pin height to accomodate this much increase and the rod's would still have over a 1.65 to 1 rod ratio.These thing's do not have a siamese block as do some of the air cooled Kawasaki,Susuki and 1000/1100 Honda stuff so you cannot simply remove the sleeve's and rebore the block as big as the other's.The sleeve's can be removed by boring them out and new ones installed but you are limited to about 76 mm bore if you want to keep the cylinder wall's at least .060 of an inch thick which you do because any thinner,the cylinder will not retain it's shape and you will have problem's keeping the ring's sealed.Someone posted a motor that had 1500 cc's and I'm not sure how you could come up with this without using a siamese block and moving the head bolt's around.Even with a 75mm stroke,you would need a 80mm bore to come up with 1500cc's.The cylinder wall's on a stock Eleven are .130-.140 of an inch thick with the stock 71.5mm bore.A 76mm bore and a 75mm stroke will get you 1360cc's,still a long way's from 1500.The 1300 combo is what I want and would be more than the suspension on old Attila could handle anyway.This stuff get's to you after a while I must admit and might cause one's brain to suffer a major malfunction if one is not careful.Thank's again for the information and have a good one.Dan.

1500

hey Dan if you read the whole post the guy made his own custom jugs to come up with the 1500.
