350x barn finds

[Homeless Dave]

So I have started to acquire parts now! Got a front hub, axle and spacers and some decals for the 86. Also found a shock for both of them.
I originally intended for the 86 to be done after the 85, but it’s actually a much nicer chassis and better to work with.

And big news! found a good running 350x engine, but unfortunately gotta let my big red go. Trading a running 85 BR for a 350x engine, not what I had in mind, but I need space anyway. So not the end of the world.

Figured I better show my old big red before she leaves to the new home. It’s really obvious the frame is bent, so I’m not too worried about see her go. Going back to the are it originally came from, and on top of that a close friend to the fellow I bought it from, almost like it’s meant to be!

In my initial post I made mention of one of the engines having been planted into a trx250x. Talking with a friend about old Hondas yielded the location of it. He said where his 250x/350x hybrid came from and it matches. As well as a few other details. Kinda cool knowing my 86’s original engine is still going. Now if only I could get him to sell it to me!

Finally have made some progress on my 86. Got the motor put in, not yet fully bolted in, but atleast for mock up. Rebuilt the brake masters and calipers, mounted the reader shock and put in new fork seals. Only needing a few more parts and I should be able to do final assembly. Only needing the header pipe (I scored a new takeoff muffler from a cut up trike from 87 ban on eBay, never been run!), airbox lid, and a throttle assembly.

Here’s some pics of how she’s looking (don’t mind my ugly mug on the 200x (21st birthday took a day to recover from).

The build is coming along nicely!

Well today I finally got the 86 going. Needs some more refinement. Needs new exhaust gaskets where the pipe meets the head, and need a few more airbox pieces, but it runs and moves. I definitely found out the fenders s protect you 0% from mud.

More than likely its just a collapsed front fork. those frames are way over built. easy fix.

She looks happy next to my 86 200x. Now that it’s running, I have motivation to make it cosmetically nicer.
I also need a new front tire, the old front max is dry rotted really bad. Any good recommendations? I have the original ohstu, but it doesn’t hold air and I’d rather not ride on 40 year old tires.

So I have it reliably running and dialed in to be a good rider without much issue. Although it appears to have blown out the head gasket. Nothin major, except the oil leak. So I got a top end gasket kit to re seal it. Can I pull
the head with the engine in the frame?

No, on that trike you need to pull the engine. You can pull the studs but that's a pain in the butt. you can have that engine out in 10/15 minutes.
get some rings while you are there, freshen it up, rings are cheap.

Engine is very fresh. Only has 10 hours or so since it’s last full rebuild. I’m thinking maybe a head stud isn’t perfectly tight and caused the issue.

I still like the Front Max tires.

[Homeless Dave]

I pulled the engine and re sealed the top end, put in new valve guide seals, lapped valves and put it all back together. It still leaks! I used a metal gasket and torqued it to spec. Even took the valve cover back off and re checked the torque on the head bolts.
The leak is mostly on the right side of the engine. Could it maybe be the oil feed line? I’ve never seen one of them leak before. But the oil leak is still the same spot as before, right about head gasket level.

Is there a crack in the oil feed line? Check it carefully. Degrease and remove all the oil from the engine and with it idling for a time see if you can see where the oil leak originates from. Were the dowel pins in place? Did someone previously deck it on a belt sander? I mention it only because I've seen it. Metal gaskets need flat smooth surfaces to seal.

[Homeless Dave]

I’ll check the oil line. All dowels were in place, looked to never have been decked or anything. Someone told me maybe the head is warped slightly.
