The seals on a GS 150 can't be installed backwards since they are a combination of the rubber seal and a metal outer structure. If there is a problem with the...
I have procured a 180SS cylinder that has been rebored to rally 200 diameter along with a rally 200 piston. There is extra port on the skirt of the rally...
A friend in our scooter club just got that modification done. He is welding the piston in order to close this port. Another norwegian friend told that this was...
Hi Trace I have had this conversion done and it works very well. If you look on the MB Developments web site, it is my conversion they are showing. I'm doing...
Chris, Thanks for the advice. Did it add noticable power? Do you know if the carb also has to be re-jetted? I took a look at their site. It does sound like...
this is the problem the bike starts ok but when I start in 1rst I have to give half the throttle before leating the clutch go or else It will die It alse boggs...
GS150 carb door, centerstand with springs and brackets, air intake, choke lever, license plate holder. GL150 20/17 carb and air cleaner. One can of original...
You definitely need the longer reach plug. An NGK B7ES would do the trick. I don't know if it will solve your bogging problems,but it'll certainly make your...
how much for the GL150 20/17 carb and air cleaner? I'm selling my 1963 GL150, and it could use a better carb. John __________________________________ Do you...
The clutch when engaged slows the engine idle speed to nil. How can it drag when not in gear? I would appreciate any insight and adjustments. This is my first...
what happens when you open the throttle with the clutch engaged? what about in gear...do you still get the low idle? congrats on your purchase, by the way. ...
Far out maybe but just an idea If you have play in the crank axis, the engaging of the clutch will press the crank to one side. This may cause seal leakage if...
It feels like the clutch is dragging somehow. It doesn't die the rpm's increase but the motor is working harder. It goes into first. I haven't tried to ride it...
Everthing feels pretty tight. I adjusted the cable so there is a little free-play; like an old triumph. I'll mess with it tomorrow. Thank you, Jim ... Far out...
Jonathan Are you sure the gs150 uses the long reach plug? I have worked on the P-series Vespa's and as far as I know the NGK B6HS (short reach) is for the...
Trace it has more power so acceleration is much better. I don't know about top speed yet because mine is only just run in and the speedo is a bit unsteady but...
Chris, Ian at MB says that this modification will require some work to the head also. Right now I have a working top end and hate to modify it until I have...
Good that the crank is tight You can also put some new oil in the gearbox, I have had restoration objects with tar coming out when the oil plug was removed and...
Hi GS150 (VS2-5), GS160, SS180, Rally 180/200, PX200 and all use the long reach plugs according to my sources. BR/ Henrik Börjeson ... the ... for ... would ...
With some help from the group I finally got the VBB1 running but for only about 15 minutes. Replaced the External Coil and Points and it started right up. Now...
... Yep, it's easy to remember: All VS prefixed Vespas = long reach All other Vespas = short reach (except maybe T5, I can never remember, but I think it's...
so it doesn't run now or it just won't get into neutral? i'd try adjusting your clutch cables first. if that doesn't fix it, you're probably going to need to...
"The clutch should start engaging when the clutch lever is parallel to the handle and there should be some "dead zone" at the end." service manual says there...
it's kinda hard to say if you haven't ridden it yet. at the same time, this may very well be out of my league. honestly, i have no idea why the clutch would...
Hi all, i'm designing an expansion chamber for my SS180 motor and need to find out the rpm so i can calculate where my powerband will lie. Can anyone tell me...
You should be able to calculate it from the wheel size and gear ratios. My source says the SS180 gear ratios are: 1st - 14.47 2nd - 10.09 3rd - 7.46 4th - 5.71...
Your calculations look good enough for me Steve, This should help heaps, thanks Mike ... ratios. ... not ... 52,800 ... 1051 ... diameter ... circumference ......
