MOPED ARMY

Does the airsal 50cc kit have a intake window in the piston? Also the homoet pipe is a top speed pipe not a torque monster. I'd run a circuit pipe if you have a lot of hills to climb.

How what a nice lifefull forum !

@ Aaron Blair

I use ipone box2 gearbox oil, and yes it suprise me also but the leather give an incredibly strong grip ... so much that the epoxy bi-composante i use to bond it juste melt ...

@ Stephen Simmons

Pretty sure no windows in mine cylinder (good observation watson !), what you mean by a "circuit " pipe ?

@ Daniel

Yes for sure but what top speed you get? Because i won't go to much fast ... in my country i can have some serious probleme for changing a moped power, i change the carburator and pipe but it's enough to get in trouble with the "order's force" if i ride like a crazy "motherfuckerteenager".

And i forget something i have in stock a 30 lb spring clutch ... maybe a good idea to try a first 30 lb and second 25lb ? (intake window look great also)

The 50cc kits with no intake window in the piston didn't make the power they should have. You really need to cut the window in the piston. Like this on the intake side of the piston skirt.

Yes, Tomos 2 Speed Automatics, or for that matter, most 2 Speed Automatic Moped's aren't really reliable when making a lot of Power, specially when going up steep hills. But you should be good if you keep the rpm's down and don't push it.

But also, modifying Tomos Bikes with in Frame Tanks isn't really a good idea anyways, they aren't stable at all.

Ok here is the skinny on the Tomos clutches. Use vibraam rubber for pads. If possible slot an a35's clutch hubs to use a3 shoes.

Replace with pivot pin in back so it opens toward rotation instead of away...swap out your tranny fluid with marvel mystery oil and c astrol atf at 4/1. The downshift is. Controlled by the internal countershaft Kickstarter cage and associated question mark spring.

Okay thanks for this variety of answer, one last question. What about the clutch spring?

I buy a set of 20-25-30 lbs spring to change my stock one. so what is the best ratio to get ? for a gently modified engine ? and more importent is the 1st or the 2nd clutch need the stiffer spring, because it's unclear.

I must not be an average tuner because the stock A3 exhaust even with with the big header still doesn’t produce nowhere near the horsepower and torque as the cheapest expansion chamber known to man!

The only stock non chamber exhaust that is ok is a puch 2hp magnum exhaust pipe and that still needs a few mods and it is actually a chamber pipe of some sorts,

Yes safari, derby, Avante Garelli clone and other bikes come with an actual chamber pipe I’m talking non chamber pipes

Ya I rode a tomos with like a 30-35 inch foot straight pipe and it blasted and I had a 3 cylinder 85hp outboard motor boat that only had a 3 inch long port coming from the cylinders right off the engine so exhaust at all no nothing and it blasted but if a exspandion chamber was put on it it would be 2x hp,

a expansion chamber exhaust is a supercharger/turbo charger for a two stroke and no one will tell me otherwise,

If you want more torque have a long header but always have a expansion chamber with a two stroke engine

So i test a 20-30lbs (2nd-1st) clutch setting and i get a good torque on hill, shifting at 18-24 mph but ... it yell as fuck. And when i get on flat what a blast! It was nice but i get so muche higer rpm that will be noot good for my baby (sob).

Conclusion: it work but it's not the good way if you want to keep your moped alive more than a 500 miles.

Know the question is how to keep lower rpm, because it's definitely the higer one breaking clutch shoes and everthing else (shame on them! buu).

Is a 65cc kit with a tinyer carb (like a 14-12 sha or a 14 phva maybe) and a Stock pipe is a way to keep lower rpm's ? ( and for sure somthing like a stokish clutch spring setting)

Yes, a 64cc kit and smaller carb with a stock pipe will make it very quiet and torquey. Also I think the cork clutches grip a lot better than kevlar or leather. Better yet are the friction material on the tomos shoes from doscycles.com.

The old model a3 exhaust that has a 22mm header.

Okay forget that if A35 and A55 have same A52 crankcase it's not exactly the same.
