86 engine swap

[lewis53]

So, I've wanted a 250r since forever and I finally picked one up last year in july for $2,000 after my deployment to afghanistan, I rode it twice and the engine top and bottom went on me. I didnt really have the extra money to fix it until my I got tax return. So I picked up an engine on ebay for $700 rebuilt top and bottom and bored to 68mm with 15 hours on it. I got the engine friday and got it running sunday evening, now I just have to put on my nerf bars, kill switch and go through to tighten everything down. I plan on riding it this weekend and I cannot wait. I just wanted to post my pics through the swap out. Needs new plastic and steering stem bearings, also want to replace the twist throttle with a thumb.

Good buy.

Yea, I snagged it up real fast, they are hard to find and expensive here are photos...I plan on rebuilding the other engine eventually. Here are photos of the new engine and the quad once I started putting it back together and with the new engine installed.

I know this is completely out of order but I'm not at all computer savvy so here are some pics of the teardown. I will get some tomorrow with it completely re-assembled.

Those first pics looked like it had a Wiseco crank??

Honestly couldn't tell you, I wish i knew myself. They guy I bought it from said it had a fresh rebuild on the top end and IDK about the crank. Once I took it apart, I noticed it had a PVL flywheel/electrical system and the flywheel was cracked and I think that off balance vibration may be the cause of the crankshaft failure.

I will post pics of the PVL flywheel tomorrow, its really strange...about the size of a snuff can and solid and it fits within the PVL stator rather than the traditional flywheel over the stator.

this isnt a photo of mine, but it is nearly identical except mine has a cracked flywheel
