Sucks. Drain your moped and try laying it on its side, or even turning it upside down, and take a wooden mallet and just lightly tap the triple tree with it, that might get them to come loose and fall out. Might also try compressed air, you might be able to blast them out.
Smaller front sprocket. Proma circuit. High-compression head. Pull your clutch and turn the two screws in about 180 degrees to tighten the springs, and it'll engage later and definitely improve your low end.
Does your Newport have an E50 or a ZA50? If it has an E50, keep in mind you're comparing a one-speed (E50) to a two-speed (A3).With a pipe and 16 SHA you'll be doing 35 on your Newport in no time.
Check your ignition timing. Bad timing = low power.Check your compression. Old piston rings = low compression = low power.Check your tire pressure. Low tires = engine works harder = low power.If you have a 504 or 505 engine on your Sachs, then "read this.":http://www.mopedarmy.com/wiki/Sachs_505/1a_performance
Anyone that thinks premium gas is doing them better performance-wise is simply deluded.Hell, if you only get 1 gallon of fuel, most of it's going to just be whatever is in the hose from the person that got gas before you.
I assume he means kill switch. On a Tomos you push the switch to the left to kill, right to on.
Sounds like a fuel issue to me.
Less than 100 miles on the rings? They're probably fine! Reduce! Reuse! Recycle!
I've got good compression and basically no air leaks, so I think it might be the reeds. I've got some new ones on the way from Benji right now. Will report back...
The problem:My Tomos idles fine, but if I give it some gas, it seems to fire unevenly. Once I get up to around 20 mph it evens out much more when it hits the main jet; by the time it gets to 30-40 it's perfect.The setup:- Tomos A3- Alukit, high-comp head- Mikuni VM20, main jet 170, other jets are stock- Tecno Estoril- fresh fuelHere's what's going on:<object width="640"

If your carb looks clean but your moped isn't starting, CLEAN IT ANYWAY.One time my Tomos wouldn't start and everything seemed to be perfect. My Mikuni VM20 seemed to be in flawless condition. But I cleaned it anyway and suddenly it ran perfectly.
I still don't get how someone could find out about Moped Army, register an account, and post a post without first noticing that there is NO mention of scooters anywhere on the site.
Well it's about 130 psi or so, but the low-end really, really blows. Like, worse-than-stock-cylinder blows.
My Pinto's got an absolutely ancient Autisa cylinder on it. Lately I've been thinking of replacing the rings. Any idea what kind of piston and/or rings would work on it?
Fresh gas and pipe, still no luck. Same result as before.I bought a compression tester at NAPA today (yay tool sale). Too low of compression is my new theory.
1) 160 jet is a typical jet size for a VM20 / Airsal setup2) It should still at least run without the exhaust.Tonight I checked my timing, it's almost perfect.Something else must be going on here.
If you're talented, mill the bottom of the cylinder instead of the top. That won't affect port timing.And if you're not that talented you could probably pay a machine shop $50 to do it.
Er, I don't know what I was thinking when I posted the last post. Tomos and Puch stroke length is 43mm, not 38mm.However I just Googled around for kitting a Batavus and apparently Puch kits fit real nice, you would just have to mill the top of the cylinder down from 43 to 38mm to get the right stroke length.
Caveat: I have never heard of anyone kitting a Trac before.That said, anything is possible, so I say go for it! There isn't much info on Tracs out there, but a lot of (all?) Tracs have Daelim copies of Laura M56 engines, which means if you can find a cylinder out there for the Laura M56 you could probably make it work on your Trac.But then again, that's assuming you could find a cylinder
Well, it's not all that new of a kit, it's probably got at least 50 miles or so on it from when it was on the A35. And right now all I'm trying to do is get the thing to run. Or do you think the exhaust would truly make that much of a difference? I don't see why it would.
*The setup*A3GM with Alukit, hi-comp and Mikuni VM20 with a 160 jet. Don't have an exhaust on at the moment.*The problem*Engine doesn't QUITE start. If I pull the choke plunger, kick it hard a couple times, then un-choke it and give it at least 3/4ths throttle, it'll run for four or five seconds, then die.*What I've already tried*- Verified I have a nice bright blue spark (ho
Unless you really do have a ton of money then I would stick to filters $20 or less. $40 K&N filters don't really get you anything except being able to say you spent $40 on a filter when you could've bought a whole new carb body.I assume you either have a SHA or PHVA. There are dozens of different air filters that fit them:http://www.treatland.tv/SearchResults.asp?Search=air+filter
1) Hm, what size jet are you using?2) Could be your timing is off.
Hm, what jet size and gas-oil ratio are you using? Have you tried tweaking the idle speed?
I'd start with Fred's Guide so you can get some general knowledge of concepts.For the carb, get a spray bottle of carb cleaner, and one of compressed air.Various fuel line sizes can work but I'd go 3/16th inch.There is debate about how reliable Tomos oil injection is and most people are probably going to tell you to remove it and just pre-mix your gas and oil instead. I tend to agr
Linda I admire your ability to be consistently nice to people and awesome.
Yep, just be sure not to get any grease/oil on the brake pads themselves.
A socket wrench extension is not the same as a deep-well socket, you know. I've seen a number of different Tomos heads and only the high-comp ones tend to require a deep-well. But that's about it. No thin-wall or anything crazy needed.
