Modern Vespa

Looks like SIP have a new iteration of the Road.

Some pretty nifty features like built in AFR and EGT bungs, a viton grommet on the spigot, and a respectable dyno curve.

No idea if it comes with the usual SIP Road fitment issues. Does make me wish they'd shipped this one before I bought an SR 3.0 for my P200, though, because I still kind've suck at welding on bungs.

Looks great for the price.

Puzzled about the o-ring missing on the 3.0. Then it would never seal properly without some sort of sealant?

impressive that the power keeps up there and doesn't look crazy peaky at all.

I think the 2.0 is absolute bang for the buck.

but man, the XL just seems to go on for-ev-er... which, I mean, not a bad thing.

The XL is the one on the 244 I'm working on… it's a bitch to install because of the nut trapped in the fragile metal box.

Not ridden it yet.

This chart is not exactly selling th 3.1. If the average scooter revs to 7000 rpm max in top gear and is 90% ridden around between 3 and 5000 rpm. Then the road 2.0 looks pretty good.

Boomstick... that's all I have on the topic

Having at least one of every Road except the Viper, I can say that they are absolutely bang-for-the-buck.

Greasy, to your comment, a RoadXL on my SprintV motor and an 8" conversion is how I'm able to Go Plaid on my VBB. Rev's for days.

The Road 3.0 has been a solid performer on my P200. The 3.1 is more of a "feature release" than a performance improvement. Hence the ".1," I suppose.

Jack, I'd have said 4-6k was a typical rider's RPM's if asked, but 100% agree with your point. I had that same basic discussion Friday about which throttle positions people mostly ride at (1/4-3/4) versus what they tune for (WOT).

In this case, I think that the features make sense--people who care about EGT & AFR bungs are also more likely to care about power out to 10k RPM's than the "bolt-on" tuner.

As I said above, I just wish that the 3.1 had been an option when the SR3.0 fell into my shopping cart a year ago.

My bad, the one I'm working with is the XL viper…

The normal XL is probably easy to install.

Nope. Pretty much all SIP exhausts are a bitch to install until you do a fair amount of fiddling.

I never really understand dyno charts.

Looking at this which would be the better exhaust for a p200e with a Otune
Using a 60mm crank.

Or is the polini box a better option.

2.0 would be my rec

If you have an aftermarket piston ie wire drawn thin rings and you really wring its neck then the 3.1 or viper would be fun

I havent got anything yet to be honest.
I havent split the engine.
I am just trying to figure out what to buy.
I would like something just above stock. Not a screamer or rev monster.
It all depends what the state of the engine is once opened. Rotary pad condition etc.
I am aiming at new bearings, seals, engine bushes, exhaust, fast flow tap, crankshaft probably piston maybe cylinder.

Something I learned from working next to a Soviet Union immigrant auto mechanic for a few years:

There's little that can't be solved with a few solid blows from a heavy hammer.

what type of riding-- city, touring, distance; and how your ride-- fast, slow, hooligan, mellow, etc is more important to selecting components for a build and what components you select will basically dictate what pipe you should choose.

it's a system and everything has to work together for it work right. you can throw all the parts together and it will work, but making it work right is the trick.

the current consensus is that the 60 crank is the way to go on any p2 rebuild be it stock or aftermarket barrel. but, this creates a whole set of circumstances in which you absolutely can not just snap it together and roll. so if you're willing and able to do that work, it pays off handsomely. but if not, then a stock crank goes in and that flavors your other choices.

^ This.

If you know what you're doing building a motor, you can do a lot of good with not a lot of money. But if you don't, you'll probably do a lot of nothing with a whole bunch of money.

Dyno's without detailed spec's of the motor they were run on are useless other than as an indicator of what the approximate shape of the curve and the maximum potential for a cylinder or exhaust is.

For example, when SIP publish those curves, they're typically for a pretty aggressive build. They've been using a Rally 200 with a 62mm crank and a Quattrini M244 in most of their tuning videos of late. That'd be about right for that Dyno. No word on port timings, intake timings (assuming it's not a reed), carb, ignition, cylinder, porting, or anything else that could influence the performance.

Gospel… put perfectly Truth about the money…

This fella measured timings:

Of course the video had to be "Sprechen Sie Deutsch"

I like the idea of the EGT and AFR outlets. It goes perfectly with my plan to build a flight engineer's station on the headset of my scooter.

Way ahead of you...

I like it. Very Cold War era Aeroflot.

The gaping hole full of random wiring probably makes it more "Aeroflot right now," but it gets the job done. The AFR could really go away, I just haven't done it yet. The new CHT is really nice, though.

Particularly like the abyss happening in the middle.

That's style right there.

Orange zip tie is classy.

you got a lot of Louis Tully goin' on there...

Ha - I love this - I think I'm gonna need to make it my screensaver!

Lemme know if you want a link to the full-size version!

Back to the future style

You should never buy anything because a shinier, faster, more environmentally friendly version is just about to be released.

2 stroke engines / products and environmentally friendly??

Vespas balancing out all the electric vehicles… lol

Anyone feel a bit rebellious chuffing out blue smoke around electric cars?

I chuff out blue smoke and our car *is* an electric car. I figure karma-wise, I'm a wash.

One of my motorcycles is fuel injected. That's about it balance wise for me.

Same.

Keep the balance right...my fuel injected KTM 990 Adventure R gets about 15~17mpg average at race pace when offroad.

my taco gets good mileage and I don't drive much. winter is approaching so I'll be riding less and using the lawn equipment less. what heat I have in the shop is propane. Dr. The Mrs. works from home.

so to keep the universe in balance I went out and bought a 70 D300 with a 383 to even up the score.

as penance I might have to buy one of bernietime's EV kits, but so far I'm feeling pretty good about the whole thing and it'll roast all four rear tires.

Let's compare

Found the pics while cleaning some old file folders. They're from an annual winter Vespa meeting right before COVID was introduced to the whole world...

That master cylinder sticks out an awfully long way!

If anyone is upgrading to a SIP Road 3.1 and has a Road 2,0 or a Road 2.5 that they want to get rid of, I'd be interested in buying it. PM me

I wanna be mad about that MC, but man... I just can't hate on the Whiskey Tango of it. needs more duct tape and bailing wire. maybe a PBR or high-life shim for good measure.

If you're looking for a Road 2.0, I can hook you up. Mine has an AFR bung welded on, too, so it's almost a 3.1. I wouldn't mind having something lower profile than a RoadXL to put on my VBB.
