Imgbb.com and imgur.com are the free sites I use. Simple and easy. Although, if you delete any photos off these sites they will disappear off of the forum, too.

I'd ask the grandkids, they love showing old people how smart they are. Your kids probably already know you're beyond help.

Sportster kick starters were designed with a 34 tooth engine sprocket. XR's can have a 20-25 or 30 tooth engine sprocket which would make it more difficult to kick start. Check that.

Thanks for the reply. Correct me if i'm wrong but wouldn't the motor turn over quicker with a smaller motor sprocket? And of course the magneto too....
Or......?

Years ago a friend bought a 1970 Ironhead xr750. We put a kicker in it. The kicker had a strange feel to it and at first we thought we must have done something wrong. I couldn't push the kick crank as fast as I could my 68 CH, even though the 750 was a smaller engine.

We finally realized that the 25 tooth motor sprocket was the reason.

To answer your question: yes the motor would turn faster with the smaller sprocket, but only if you can push the kick starter as quickly as you would if you had the stock sportster 34t sprocket. The change in the primary gearing makes kicking it harder. I think the slower kicker speed and the faster engine rotation kind of evened out. The bike was not hard to start.

Hard to say if an aluminum XR would act the same. It has a shorter stroke and maybe more compression?

And thank you for your reply. According to the service manual 72 to 80 xr stroke is 2.983 compression 10:1. Believe it or not i also have a 68ch. As you probably know stroke 3.81 and compression 9:1. It can be a bit of a bear somtimes for this old 135 lb. Fella but It'll go. Thanks again for all replys and help. Will keep you in tune......
