i was yelling at the screen the whole time u forgot the guide for the timing chain. lol happens to the best of us

Just tore mine down and the timing chain guide was missing! Someone probably made the same mistake you did and just ran it that way. Chain ended up wearing a hole in the cylinder and someone jb welded an aluminum patch on it. Luckily I was able to find a new to me cylinder . Valves are burnt and I'll be disassembling them tonight to see what kind of parts I'm going to have to scrounge up. Picked up the bike for 800 bucks which, in this market for old trail bikes, is a steal. I hope to bring her back to her old glory soon. Thank you for sharing your rebuild. Between this and the proper shop manual, rebuilding this engine isn't that difficult.

Love watching these bro. When I was your age I was doing the same. I'm 25 now and I couldn't yell you how much shit I have learned over the years from just tinkering with machines like you do. One of my favorite things ever is just being in the garage wrenching.

Andrew you really have great patience... The whole time you were reassembling the engine, I kept thinking that you hadn't installed the timing tensioner...🙄🙊 Oh well,on the bright side, you are now proficient with tearing down and rebuilding Honda 250s!!!💯👍

I was going crazy when you started putting the head back on without that guide! always keep your eye on what parts you have on the bench.

Nice job getting that old bike running again. That's a lot of work.

Reminds me of rebuilding my first bike. 1974 xl250.

Good stuff buddy . Replacing piston and rings in my xl250s , sure I will revisit this vid again when I reassemble

Great job Andrew, keep up the outstanding content . You need to get some merchandise going.

I have a 1983 XL250r,... 29,000 mile's,... I bought it new when I was in the Army (Ft. Bragg N.C.... Meridian Honda at the time),....I'm gonna have to do this,... bike run's excellant,... but it's time,... was wondering the best place for part's,... your's sounded excellant after the rebuild,... video was very well done,... you hang on to that bike,... I've had fun with mine for over 40 year's,... still take's me to the cafe,... they were built good,... in "83" it costed me $1172.00 dallor's,... everything included,... time's have changed,... take care........

I enjoy your content in all the formats. Keep up the good work.

damn very informative video! eagerly awaiting the second part

Thanks. I have to dismantle my cb250rs that have the same engine. It will helps. Good work

I got a Honda Xl 500s recently. When driving, it is switched off twice. It had no oil inside when checking. Now the Kickstarter is blocked and won't come down. I'm trying to open it up and hope to revive it.. I could see, how the engine looks like, thanks to your video.

Great job ! Very well done 👍

you said you flipped the timing 180 degrees. Now I’m confused on what the correct way is

Great job on the rebuild. These old XL's use a metal valve cover gasket which help clearance the cover on the camshaft, you may want to find one eventually.

I like the cardboard bolt holder

How did you flip the timing 180 degrees? Thank you.

The ring end gap WEAR LIMIT is 20 thousanths (0.020"). If you stuck a 0.020" feeler guage in there and it fit then the end gap is too big. The optimal operating range is 6 to 10 thousanths (0.006- 0.010") and you absolutely replace when it gets to 20 thou. Since the rings were new your cylinder bore is outside of the specs for the rings (and probably the piston) you used.I'm sure it's running well and maybe not even smoking but if it were me I'd take another look at the ring end gap now that they have taken a set as well as the piston to cylinder clearance.

Do you know where to find new rebuild kits for this engine

I have a 1985 xl250 I'm having trouble finding parts anyone have any suggestions
