How do you know when you have the correct pilot jet in there, is it not a matter of the mixture screw not being able to adjust out to 3.5 turns ? If it canít adjust out to 3.5 turns do you then not go to bigger pilot and visa versa to smaller? Had watched a video on what to look for on idle jet, rev it and if it comes back to idle consistently and right away itís good, checked mine and it seems good.
I donít know why but I find this jetting stuff the most interesting. I had found a huge difference in mine when I put the 140/BE5 from the 160/BE3 even down low in first and second. I also thought the low temperatures your getting meant it was running rich and not lean, that is confusing.
Love the rear sig lites you made up.

Getting the low speed set correctly definitely has a bit of a black art to it, for sure.

The biggest mistake people make when adjusting the idle is not getting the bike up to its operating temperature first. That means go ride it around for 2-3 miles before you even start.

After that, you can start to actually adjust it.

The way to think about adjusting the idle is to remember how it works. The idle jet provides the air-fuel mixture at a fixed ratio, as determined by the jetting. It's an air corrector & main jet in one, and while it adds mixture across the entire throttle range, its relative contribution becomes fairly negligable after 1/4-1/3 throttle.

The mixture screw meters how much of that mixture is allowed into the carb (out is more/richer, in is less/leaner). The slide position (as set by the idle screw) determines how much air is being allowed in through the venturi, which in turn sets the idle speed. So you have three variables, one of which is semi-static (the idle jet/mixture ratio), and two of which can be adjusted dynamically (mixture volume and venturi air volume).

One thing that often gets overlooked in the whole thing is flywheel weight. With the SIP/Vape ignition and a 150/177/187 motor, I like to set my idle at about 1,300 RPM's. With the 210, I'm finding that 1,100 seems to work well. I know that Jack sets his at 800, but he's better at this than I am.

The two key indicators of idle, IMO, are return to idle and takeoff crispness. Return to idle should be a solid drop, only taking a couple seconds to fall from full RPM's back to idle, with no hunting (the "pip-pip-pip" sound) as it spins down after releasing the throttle, whether blipping it or coming off acceleration or cruising. This is critical, because that's what keeps you from seizing when you hit the off ramp.

The second indicator is whether the motor bogs or hesitates when you give it throttle from idle. This can be either lean or rich, so to be safe or if you're not sure, make sure which side you're on by, for example, if you think you're rich, adjust the mixture screw out half a turn and make sure it gets worse and not better.

When adjusting, it's also important to know if you have a fine- or rough-threaded mixture screw, because 1.5 turns is the rough screw ideal (someone check my work here) and 2.5 is the fine-thread ideal. If you're further out than that, you need a richer jet. If you're less than about one turn out, you need a leaner idle jet.

I hope that helped

And getting it right is something you can do over time. As you're out riding, you'll decide if it's too rich or lean for your tastes once it's close, then you pull over, give it a 1/8 or 1/4 turn adjustment, and ride on.

Thanks Chandler this is a great explanation and really helps in my understanding, Iíve never thought of how the flywheel and type of ignition would have an effect in the tuning. I think Iím too busy following along with each persons journey on jetting and getting myself confused as to why one would be so different than another. Just when I think I can perhaps add some insight as to why to do this setup everything tends to be wrong.
Such a large scale of Atomizers is a whole different chapter of confusion.

More progress. Electrical is done other than getting some front turn signals. I'll bring the Vape regulator over with the ignition on the motor, and it'll go inside the frame. The fit and quality of the bulb holder left a lot to be desired, but I'll make do for now. I expect that I'll eventually replace it with an LED, but for the moment I'm rocking an incandescent.

Drilling the headset for the turn signal switch was over of the more agonizing things I've done on this project, but the end result both looks good and I think will be comfortable to use.

The autolube oil tank arrived and I fabricated a bracket to hold it in the glovebox like FridayMatinee did, so that'll all bolt together soon enough.

And I lost the horn screw clips, so I had to order more of those. Of course.

One question, though, is what people use to paint the great shift numbers and dots. Is it just touch up paint and a fine tip brush?

I've always raided managements (wife) nail polish. Guaranteed to have a nice complimentary color! The I fill the recessed numbers with paint, and carefully wipe away what sits above the recess. Always turned out better than stock.

Made a lot of progress today. The motor is in the bike, but the shifter, rear brake, and clutch still need to be connected and adjusted. The CHT and Tach are installed with wires run inside the frame for once.

I had to improvise a little on the throttle cable, which was too long (too much exposed inner), so much actually be for another bike. It's crimped on both ends, but I had a cable bend that I was able to cut off and make a spacer, so that problem is solved.

The oil tank is done. I would have installed the glovebox cowl, but didn't realize I was out of M6 nuts until I was no longer interested in going to the hardware store, so that'll happen in the morning.

The only other notable task at this point is installing & wiring the SIP regulator/rectifier, then dropping the gas tank in and final headlight install are pretty much all that's left.

The motor was nice n' clean when I pulled it out of the Sprint, which is a good sign since it's seen a decent amount of riding. Carb is still only about 85% dialed in, but that may never happen since it's being held back by the exhaust and I don't want to order one unless it's the final pipe, probably the SIP Nordspeed, and that's still backordered, though things are starting to trickle back into stock at SIP, e.g. the 62mm bell crank I'm contemplating the hell out of.

Sadly, the forecast tomorrow is rain all day, but that'll keep me from hurrying to get on the road, so that's not the worst thing.

I even washed my Pinasco tubeless rims & tires before installing them, so this bike is almost certainly the cleanest one I've ever owned right now.


Progress!

I mean that the exhaust doesn't allow enough flow or provide meaningful resonance, so the rest of the motor can't perform as well as the parts, porting, and settings would normally allow.

Upgrading the exhaust would add a few horsepower right off the bat, I just don't want to buy an interim exhaust that I might be replacing in short order.

Have you tried running without an air filter to get more air into carb, would that make a difference?

I run with the carb covered, but just bellows to frame; no filter (much like myself) and with a venturi. You can see it in the picture I posted without the airbox cover.

The problem is that the exhaust doesn't allow enough flow through it (the outlet is relatively tiny), plus whatever it has for baffles, which are a lot given how quiet it is, and no expansion chamber.

And Sweet Roll is rollin'!

I have a couple things still to figure out, like why the center stand won't fully retract. And there was the Headlight Incident, which is repaired-ish, i.e. I bent the bezel back into shape enough with pliers to re-install it. As much as I hate to admit it, this is at least the third time I've had a headlight fall out or bezel fall off on me. Meh.

Plus, it's not wanting to idle, but that could be because the gas is pre-mix until I was sure the autolube was primed, plus some WD-40 mixed in that I sprayed in the gas tank after I washed it out to prevent flash rusting.

Lessee...what else...

The horn is only held in with one screw right now, because I need to drill holes for the other three (the horn has three mounting holes, the horncast has four)

The handlebar grips slip like crazy. Need to glue them on. I think people have suggested hairspray for that?

I still need to get some nail polish to paint the gear markers.

The CHT is not getting power (I rigged up 3v to replace the coin battery, because it went through those suckers like weekly), so no CHT right now.

I need to fabricate a new rearview mirror bracket and install that.

Oh, and it has no speedo. It's just for show.

But it's fundamentally rideable and the bits that are left are nothing I can't fix as I go.

Video of the first roll out still to come.


Sweet Roll!


Good as new!

Pretty cool Chandlerman - except that angry eyebrow of a bezel you have there...
Great color scheme - must feel good to see it so close to finished.
Look forward to seeing it in person.

Looking good. Thought it would take longer to get this far. Few weeks tinkering and it's done.
Needs a great big fat expansion. Pipedesign being the best choice.

Video is up...definite comedy of errors...

It'll definitely get a big fat expansion at some point, Jack. I'm partly waiting for supply chains to catch up and partly not wanting to drop a wad of cash on it right now.

The eventual plan is still 62mm bell crank, VForce4 reeds, and probably a PWM38 carb, which should be more than stupid-fast enough with the right pipe.

CM2, the bezel was unfortunate, but the video somewhat explains it. I just put it on the punch list and will get to it next time I order parts.

The autolube feeding from the glovebox tank is working just fine, but I had to prime it by sucking oil into the tube initially. Patience might have been a virtue there, but in the meantime, suction got the job done. I'm sure my neighbors loved hearing me rev the motor until the air bubble was gone.

Also, it just occurred to me that the oil tank might need a breather hole...better check on that before Bad Things happen...

Congrats! Some progress is better then no progress.

I had the same problem with my headlight. When the glass fell out on a long ride. I stopped by a buddy house and found a translucent plastic box and cut out a square to replace the broken lens. It was OK until I got another lens and adjusted the tabs on the lens holder so it want fall out again. I still keep the plastic homemade lens in the tool box.
Is it the the spring that's preventing the center stand to not retract or is the center stand hitting the exhaust? Sometimes with a P200 motor it needs a side stand or a MRP center stand adapter especially if you get an expansion pipe. Never could really figure out why some center stands work and others don't. Maybe it has something to do with the lengh of the rear shock or/and its extension or the type of exhaust being used.
BTW, the front fork link looks flat and normally has an upward angel similar to a Sprint fork link. Was the new spring or front shock longer then stock? Sorry if I missed where you mentioned this during rebuilding the fork.

Good luck with getting it to where you want it!! You're almost there.

Now as we all know, I run the sort of workshop where there's never a Work Stop Accident and qwality is the utmost importance.

So not that anything like this would ever have happened in my workshop, of course, but if the center stand had been installed without the brackets through the stops on the stand, it could in theory, cause the center stand to slide out of position to where the exhaust interfered with it and prevented the stand from retracting fully. In theory.

And I don't know why the birds were so loud in the video, SoCal, other than that we have a lot of trees and, apparently, a lot of very vocal birds.

Now, though, I can get back to fussing with the idle and figuring out the (lack of) power to the CHT and maybe even go for a ride if it ever stops raining.

Love the wooden floor, I walk on concrete all day and if I work in shop after itís back onto concrete but with runners.
I kind of enjoyed the sound of all the birdies singing.
The inside of the shop is wood, 3mm underfloor padding/moisture barrier, then vinyl flooring. It's MUCH better for standing on than a slab, plus cheaper to build and since it's considered a "temporary structure," that means it doesn't increase my property taxes.

Sweet layout. I like the idea of not getting taxes upped.

Also, it just occurred to me that the oil tank might need a breather hole...better check on that before Bad Things happen...
Ya know, I had that exact same thought the other day. Wouldn't be hard to drill a small hole in the cap. But how big? Is it even needed? I dunno.

Soooo....

I fixed my CHT electricals. I had somehow managed to convince myself that red was black and black was red on the input lead. Amazing how much better DC works when you have those hooked up correctly.

Also, as previously mentioned, the center stand is now working correctly. It fixed itself while I just took things apart and put them back together

The motor started first kick for me today. It still sags coming off idle too lean, but is great if I choke it a little bit and blip the throttle, which is weird because I have a 50-120 in it. Maybe I need to clean the carb again. Or swap it out and see if that resolves the issue. At least it mostly idles.

Speaking of the choke, the choke cable must have come loose inside the frame, because it was holding the choke open. For now, I just disconnected it because I couldn't be bothered to pull the tank and I'm not sure what I'd do to properly fix it once I did right now, anyway.

Oh, and I still need to deal with the horn, but that's just templates and drilling some holes. It'll happen.

Looking at the product spec's, it comes with a vented cap, so that answers that question!

I'm going to swap the carb for the Known Good 24/24e off my SprintV motor and see what that does for me. I also need to get a fresh spark plug. Right now, I'm still using the one that was in the motor when it came to me, so it might not be the freshest.

Progress!

I swapped the carb for the 24/24, as threatened. Gave it a good cleaning as long as I was doing, then installed it and started working on the setup. That gave me a little bit of improvement, so I swapped the plug for a new B9ES and that made a big difference, too.

I just got back from a run to the hardware store for more cutoff wheels for my angle grinder so I can finish fabricating a rearview mirror mount. Rode there, all was well. It's about three miles of mostly 50 mph-ish road and the CHT settled right at 100C while cruising.

And while I was out, I managed to run it out of gas. I was trying to burn as much of the pre-mix as I could before I filled up, and I succeeded to the point I got to push the scoot a couple hundred yards to the gas station. Filled up, it started first kick, and I rode back home on the same road and all was well.

Idle jet and mixture aren't done yet, but they're rideable, which is a good start.

Where is the jetting and timing set? These are way less tolerant of running lean. Don't want the piston in the hall of fame just yet.
