So begins a project
The back story: I have not ridden a bike in quite a few years but have been missing it. I spent a lot of time on dirtbikes in so cal and the desert growing up and into my 20's, now I'm 41. I thought about getting a decent dirt bike but I came to the conclusion that a dual sport would be more my style these days. I looked into what was available for decent money and found a 2011 klr650 with a blown motor. Ahah, a project. I checked CL and found a used one cheap so off I went to look at the bike. Was it meant to be?
When I got there it had busted, missing plastics as well so I made an offer and bought it. When I got it home I removed the valve cover and found the cam bearing cap bolt? Had pulled from the threads and the cam ate into the head rendering it unmachinable? Or I believe so anyhow. So I got ahold of the dude with the used motor and went and picked it up for a good price. Long drive though, but I knew that.
The downside of the used motor is that it was from a 2007. I had lurked some forums to be sure the motor was compatable before buying it and read some posts that it was, and 2007 was a decent year motor? It also has "2900" miles. It does look very clean. I pulled the valve cover to make sure it did not suffer the same fate and found it nice and clean and the cams look brand new. I am unsure of compression as I do not have a tester. It feels a little easier to rotate with a ratchet than I would think? But these are low compression motors. It does seem to engage all gears and the clutch feels ok.
Time to swap motors:
The first thing I noticed is the new motor does not have the egr? Tube coming out of the head. Does not even have the holes drilled just the blank embossment, so I guess I am deleting it? And the piece the hose goes to on the frame can be deleted as well?
The second issue is that the new motor has a 5 wire harness coming out of the left side cover. The old has a 7 wire harness. Can I delete the red and white wires and only hook the three yellows and the remaining two? Or do I need to swap harnesses?
Thirdly, do I need the bike on a stand when I pull the motor? And does it come out the right or left easier?
Thanks for reading and any help is greatly appreciated. I will post pics as soon as I figure out how to...
