1. Vespa Grande Jet?
Forum: Repair
I have an 80 Vespa Grande, all stock but a high flow filter and a factory appearing but a little better flowing muffler. I upjetted and it started like a champ and ran great for a 30 minute or so ride, but soft seized. I upjetted two steps because I felt like a soft sieze is a really lean condition, and with the two steps up jet, it will fire when I am pedaling, but not catch and run on its own,

Ok, thanks. Are front and rear brakes both set up on one lever then?

Nope, I am in Minneapolis area and have had it for a while.

Thanks everyone for the advice!I am surprised the CJ8 is the correct plug, but I'll keep trying that.When we're talking about the switch, you say the forward and backward are off. Just to be clear, when the switch it pointed lengthwise towards the front and rear of the bike the ignition is off, but when turned sideways, the ignition is on?As it is now, the decomp is set up in the right
5. Re: Starting a Motobecane SPR
Forum: Repair
So there is no ignition switch to speak of then? On my bike, it looks like someone set the decomp to run on the brake lever on the right grip. As far as I can tell, twisting it forward doesn't do anything.
6. Starting a Motobecane SPR
Forum: Repair
I have an old SPR. Based on the carb, I think its a 62. I tried to fire it up for the first time since I bought it, and it won't seem to fire. How do I start it? Is there something I am missing? It has the lever on the right hooked up to the decomp, but I don't do anything with that since I don't with my Vespa. The carb is clean and the petcock is new and flowing. I don't

Forgive my idiocy here, but I am not sure what you mean by choke plunger. This is an 82 with all the hoses, etc. I understand that an automatic choke is built into all that somehow. Everything seems to be in good shape, but I am not sure exactly what the choke plunger looks like.

Alright, I am ordering a pile of gaskets to seal everything up. That includes carb gaskets, carb to intake gasket, head and base gaskets. I took the intake off the case yesterday, and it looks like one seal that might be failing is the rubber gasket on both sides of the reed block, reed block to case and reed block to intake. I can't seem to find a replacement anywhere. Is RTV a logical c
11. Motobecane SPR Petcock
Forum: Repair
Anyone have an idea of a petcock that will work on a Motobecane SPR tank? I thought some carb cleaner and compressed air would let it flow again, but no such luck. Is there one for another moped that will work?
12. Re: Motobecane SPR Update and Question
Forum: General Discussion
You were right. It was on there, just caked in grime. I wrote down the VIN. Is it one you can decode to mean certain things (year of manufacturer, production plant, etc) or is it just a number?
13. Re: Honda Express rpm all over the place
Forum: Repair
Thought I did because it reacted to spray stater at the joint between the intake and the carb, but I sealed that up and still have the same problem. I am going to get new gaskets for everything on the intake side and see if that solves anything.
15. Re: Motobecane SPR Update and Question
Forum: General Discussion
I still can't find a VIN on this bike for anything. I have looked all over the normal places on the frame, and down by the pedal crank and center stand as others suggested. Am I just a total fool? Is it a plate welded on or riveted on, or etched into the frame directly?
16. Re: Honda Express rpm all over the place
Forum: Repair
The rtv gasket between the carb and intake didn't make any difference. I can't seem to find the air leak. If it has such a direct effect on idle speed, I feel like it is probably in the intake tract somewhere. I'll see about intake gasket and o-ring replacement
17. Re: Vespa Grande won't restart
Forum: Repair
Bought and replaced the coil. That was definitely the issue! It cold startsa lot better, and fires right off on warm start which is great. It also feels like it has more power than before? Anyway, glad to solve it.
18. Re: Vespa Grande won't restart
Forum: Repair
I had spark when it was running. When I tried to restart it and it wouldn't go, I didn't check for spark again because I had some just minutes before. I am starting to feel like that is the problem, that I lost spark. The plug did have some fuel on it when I pulled it, so I think I am getting fuel. It has done this before when it will run fine, then after shutting off, I need to wait

I need to dial in the air mixture and idle speed first and I need the airbox off to do that. I'll mount the airbox before I drive it anywhere. Hopefully that o-ring gasket issue will solve my rpm problem.
20. Re: Vespa Grande won't restart
Forum: Repair
Could this be an electrical issue? Coil maybe? I have heard that bad coils tend to work when cold, but stop working when warm. Maybe running it warmed it up, and after I turned it off, it was too hot to restart? Does replacing the coil make sense to anyone?

What? It was on level ground. I moved it several times before trying to start it again and again.

I have an 80 Vespa Grande, stock everything but pipe, air filter and jet. The carb, base gasket, head gasket and spark plug are new. I started it up today to take it for a brief drive. It fired right off, took a little to settle into an idle but then I took off. I drove for 10 minutes or so around my neighborhood then stopped back at the house to grab a few things and go for a longer ride (like

I checked the petcock again- flows great in reserve, mediocre in on, so I run it in reserve, as I have been doing. I checked the carb drain screw and it let gas out so it is definitely getting gas to the carb. I checked the plug and it looks super light, so certainly a lean condition. I started it up again and sprayed all over with starter fluid to see if I could find an air leak. It stumbled

I see your seat cover seemed to be in the same condition mine is in. Have you done anything to solve the seat cover/seat foam issue yet?

I have a photo that makes it look like 488 S 7/62. If you need the whole thing I can get it next time I am working on it, which will hopefully be in the next few days.

I also looked for air leaks on mine and couldn't find any at the head or base gasket anyway.

Ok, here comes an idiot question -- how do I adjust my float level on a stock 82 Honda Express carb? There is no adjustability apparent to me. It looks like the float valve just sits in in between the two plastic tabs on the float. Is there a way I should be adjusting it? And to what?

Forum: General Discussion
I agree that it depends on the person and how well they take care of their stuff. I have known poor people to take great care of their stuff, or have total disregard for their stuff. I can say the same about wealthy people I have known. Moped buys have been the same, got some crappy ones and some nice ones from all ranges of income and age.
