Nice work, sir!

Props for the taillight de-bodge too. Looked like the PO was as good as soldering as they were with the rest of the work.
Thanx man!

My soldering on the brake light switch wasn't great (literally first solder joints ever), but it's miles better than what I saw when I bought the bike.

So, yeah now I have a functioning brake light on deck. Went for another, longer, late night ride. Got it out on some hilly, curvy county road, WOT & haulin ass. Bloody fantastic!

So after a few rides I've realized I have sort of a rattling, chattering sound coming from my engine at idle. Sort of a "tick" that occurs with every stroke of the engine. It's not the shroud or fan cover rattling, I've removed both.

Looking for thoughts on what might be causing this, and how concerned I should be.

Tried capturing the sound here:

Pulled the motor. Again. No sweat, I'm getting used to it.

Looks like I've got too much clearance between piston & cylinder, and what I was hearing was likely piston slap. Gonna get the bore measured, see what the next oversize is, get it bored, and order a new oversize piston.

Realistically I should have done this way earlier, but I was hoping to avoid 500mi of running in a new jug before tear-assing around on this bike.

Oh well. After this, everything but the cush & the gear stack'll be brand new.

piston slap is where I was going in my thoughts, sounds kind of like my malossi kit did based on the video.

you could probably have swapped top ends without pulling the engine again, but it's done now.

After having just pulled this off, removing the engine is much easier. It was a right pita not removing the engine.

Well RATS!

Oh well, it will be even better after. Is there an oversize Grand Sport piston that would benefit this engine? My son has my old '76 Rally and just got it running again using Mac's old Femsa CDI after the ignition died. It does run now but cylinder is worn, compression is low and so is the power , so we'll be watching this closely.
Here Mac's  old CDI back on the job & ready to go. Thank you my friend!

This was my thought 100%
Unless I needed to get the jug off on the side of the road for some reason.

At this point dropping the motor is pretty routine, and doesn't take me very long, especially with a new tip MJrally wised me up to: leaving the entire carb/airbox assembly with the frame.

you can leave the selector box with the frame as well, so you don't have to reset gear cables. I've never seen the carb box left with the frame, but i guess it has advantages also. probably more so if you have autolube. I've still never had autolube though.

Semi off topic, but on small frames I leave the rear brake backing plate with the frame when I pull the motor. Only 3 nuts, you gotta pull it anyway to clean motor properly and now you don't have to fight w/ the rear brake cable.

Yeah, I figured out the selector box trick on accident years back. If I recall, I think it was bc I was afraid I'd never get the selector cables working right again if I took them off the box lol.

I missed having an autolube bike… right up until I started having to reinstall an autolube tank to a frame… I swear, that is just 3 bloody bastards bodged on a big bullshit bastard barge. So annoying…

So… I didn't end up get my cylinder bored oversize after all; MJrally had a fresh top end on hand, and he made me an offer I couldn't refuse.

I installed the new top end on Saturday, but I was fighting a cold and seriously off my game. As I was unbolting the motor from the stand getting ready to install it to the frame, I spotted a wrist pin circlip on my workbench… so I'd only installed one on the piston. So I pulled the jug again.

Then after I installed the motor, I got a little ahead of myself, and tried kickstarting it before I'd tightened the kickstart lever bolt. Broke the lever. That's when I decided to call it a night.

I'd ordered a new lever the night I broke it, but I didn't want to wait on its arrival to resume work, so I swiped the lever off my Allstate on Tuesday, got all the cables hooked up and adjusted, and fired the bike up.

I think I can definitively say that the rattling I was hearing was indeed piston slap, because it disappeared with the installation on the new top end.

Took it for another late night rainy ride, and it ran great. I've taken it on a couple rides since and it hasn't blown up or left me stranded. I'm getting a good feeling about the status of this bike.
Oops…

Kickstart lever looks a little wonky, but it's getting the job done in the interim

Put about 280mi on the new top end, so thought I'd take it on a longer ride w/ some higher speeds yesterday.

About 18mi from home, I was doing 58mph, a truck wanted to pass me. Rolled off the throttle from wide open, and immediately felt a strong tug at the rear wheel. I was fast on the clutch, but the engine quit, and I coasted to the shoulder. Pulled the plug, and it was pretty light. Cycled the cylinder with the plug out to get some air moving, cool it off.


20 min later, started first kick. Rode it hard home, maybe not as hard as I rode it out there tho.

Soon as I got home, pulled the motor. Again. Got the jug off, and sure enough, seize marks on the piston and cylinder wall. Nothing I could catch my fingernail on, although in one place on the cylinder wall, I could just barely detect a scratch when gently moving a small screwdriver tip across it.

Kind of a bummer, but it was a totally an epic ride.

Carefully clean it up. No harm done. Was running way too lean. Plug and piston crown both confirm it.
Bigger pilot and smaller air corrector, next time out.

Yeah, it'll be fine I'm sure. Gonna pick up some sandpaper and muriatic acid this weekend.

Jetting is stock p200… 160-116-be3 if memory serves (I'm not near the bike now)

I've been informed that 116 main probably is low for long hard rides. Gonna pick up some b8es plugs for outta town rides as well.

Yeah, OG pipe.
i'd bump it up to a 118. And if you're on the highway, then probably a BR8ES plug as well.

Not a red herring or anything, this will annoy all the autolube fans…

I love the novelty of autolube and it's a neat design, for around town, with a short burst on the highway or higher speeds I can deal with, but anything more sustained, I'm not sure I'd trust those little cogs to pump enough oil around to keep up with WOT, especially when you roll off the throttle and rely on that tiny hole that's left to feed fuel AND oil…

Plus the fact that it's an iron cylinder which doesn't help anyone with the heat that the engine is enduring on highways.

I'd always understood that autolube was the better lubrication system owing to lubrication being applied as a function of crank rotation. Something about the possibility of premix potentially leading to underlubed condition in the event of coasting?

My previous autolube bikes did fine, rode Portland to Eugene (roughly 100mi) on I5 a number of times, wide open the whole way, no problem, but that's strictly anecdotal, of course.

Not arguing your point, just relating what I've heard. I've got no horse in this particular race.

So, I used muriatic acid to remove the aluminum from the cylinder, then hit it with 400g sandpaper to remove the light scoring. 400g sandpaper on the piston as well. Came out really nice.

While the motor was out I took the opportunity to use sandpaper & glass to lap the cylinder & head, as I'd noticed a little leakage.

Today was my first ride since reassembly. About 1 1/2 miles from home, the bike quit on me while idling at a stop light. I pushed it to the side of the road, pulled the cowl and saw that the oil hose had somehow come loose. A litany of profanity ensued.

I reconnected the hose, got the bike started, rode home, and pulled the head to inspect the cylinder, at which point my hopes were utterly dashed.

I think I can salvage the cylinder, but the piston looks pretty buggered. This is just… really some cursed shit right here. I can't even get my head around it.

Oh, and the irony of this considering my previous post is not wasted on me.

Looks ok to me. Clean it up, again. Put 1% oil in the fuel until sure the auto lube is online.

Silver lining, you weren't blasting down a highway…

Kinda good it happened at lights.

Again, autolube is a great little design… love the thoughts behind it, but I wouldn't run it on anything that isnt an iron cylinder and running any speeds above 50km/h.

Just personal preference. Maintained well, I'm sure it's fine, just not for me.

Oh N.B… if you premix, you run a little lean… so that'll make it a little hotter… so probably good to take it easy…

I'm sure this thread is starting to look like a bit of a shitshow…

RE the autolube, when I installed the motor I not only double checked that the hose was connected, but that the pump was primed and feeding oil as well. Something I always always check. Can't for the life of me figure how it came loose. Crappy clamp & vibration?

And yeah, def glad it didn't happen at speed.

Oh, and during all this, spotted a couple holes in my exhaust, so add that to the parts list.

I went through the exact same shitshow with my 200 engine. The oil line was loose and developed a large air bubble and seized. One of many shitshows.

Did you go over any big bumps? Is the suspension tight or bouncy? Is the oil line a little short due to shrinkage? I ask because the whole motor moves with the suspension, so it is possible for it to pull things out if there isn't enough slack. Though in my experience the issue was always with the plug wire or other wires going into the CDI, when I had the Femsa style that mounts to the chassis. The rear of the motor would move more than the front.

No gnarly bumps. I actually barely made it out of my neighborhood. Hose is brand new to this build, ordered from Mercato. I actually wish I could say I forgot to attach it, as embarrassing as that would be. At least then it would a mistake I would learn from.
