There are many basic theories for breaking in an engine. It is very difficult to do, but always worthwhile. Frankly, if you don't break in an engine properly, you'll never have the best performance and reliability you could have have.The basics (that I use)1. use an extra oz. or 2 of oil.2. Vary the revs, but never open it full throttle until at least 150 miles, and never for longer
Keith Wallace — 18 years ago
First off, you shouldn't run full throttle until you have at least 200 miles, preferrable 300. Top speed on a stock tomos usually falls between 28-32 mph.

http://www.vtcycles.comSteve hooked me up with a 65cc metra kit, proma low boy exhaust, carb jet, and transmission tuning parts for a great deal. Check him out. Be aware, you'll have to make a custom bracket for the exhaust. Runs great, super quick takeoff, and top speed of about 42-43 mph with the weights I have in it now.
Keith Wallace — 18 years ago
it's a front sprocket, yes it'll fit a tomos, that's what you found it under, correct? It'll add some top end, but cost you acceleration. Stock I believe is 26 tooth.The euro kit won't add a lot of speed with the stock exhaust, pick up a techingas or techno exhaust, parma kit or airsal kit, and 15mm carb and intake for the best increase in speed.

I had the polin kit, and it usually runs good somewhere between 76-84.

I'd take the head off, and put it back on again, it may be slightly off line. Did the bolts tighten smoothly (i.e.- no cross threading)? Are you sure the problem isn't with the fuel flow or the spark plug not firing? Since you just added so many parts, there could be any number of things. Unbolt the intake, exhaust and head, and rebolt them all. Make sure your cylinder is all the wa

That looks too lean. Check this picture for a more acceptable colorhttp://www.mopedarmy.com/forums/discuss/download.php?f=1&file=1086890525_bougie2.jpgYou want the color to be a coffe with cream colored.

Either the 80 or 85cc kit will require a massive amount of work- they are larger than your crankcase. You would have to weld material onto your crankcase, then grind it down, and finish the inside to mount the kit. You'll also need a bigger crank. It's a lot of $$ and hard work. The polini kit, ,15mm bing carb and intake, and biturbo/estoril/circuit pipe will give you a solid 40-50

You will see a signifigant increase in speed, though your acceleration may suffer a bit. You should near/exceed 40 mph.
Keith Wallace — 18 years ago
25 mph is pretty average for your moped stock. You may want to try cleaning the carb if it's been sitting for a long time, that may help a bit. If you are looking to kit it, the polini kit, 15mm bing carb and intake, and any exhaust will work well. I've seen numerous puchs with this setup work well. Be prepared to spend around $300+ on the parts. It isn't a difficult job, but y

If you get your cylinder bored out-there are several things to consider-you will need a larger piston and rings to fit in the larger diameter of the bored out cylinder. Exactly. Wiseco makes a huge # of pistons, but finding the right one for your application would be a nightmare, because I'm sure they don't sell bored out pistons for Panther mopeds. So you'd have to have some dam

You don't need to run more oil neccessarily, but you should have to put a larger carb jet in your carb. Is that picture of a new spark plug, and is it with or without the bullet pipe?The only way to determine what jet size you need is to get a brand new spark plug, do a full throttle run for a 1/2 mile or so, the shut off the engine at full speed with the kill switch. Then check the plug c

A piston ring sleeve would be unneccessary, you can usually compress the rings by hand enough to slide the piston in the cylinder. A good pair of circlip pliers (very thin needlenose work well) make the job a little easier.Some tips off the top of my head:Make sure you remove all the old gasket material before putting on the new ones.Check for bits of flashing in the cylinder ports and intake, an

unfortunately, most increases in top speed will cause a decrease in take off, and vice versa. If you really want to go faster, you'll probably have to lose some take off. What have you done to it to make it faster than stocK?
Keith Wallace — 18 years ago
yep, its the best kit around- better porting, reed valves, and clean construction.
Keith Wallace — 18 years ago
yes, but you can get a better kit athttp://www.mopedwarehouse.comfor a better price. Get the polini kit, 15mm bing carb and intake, and whatever pipe you'd like, you'll be flying, you can use the stock head, and Chris is a good guy. Call him or post on his forum, it's difficult to catch him via email.You may or may not be aware of this, but 2 speed puchs fail at a higher rate than

go to http://www.vtcycles.com- I'm pretty sure they still have the proma exhaust pipe for this bike, they may even still have the 70cc kits, too.

nope- the fa50 is one of those mopeds that performance parts pretty much have to be fabricated for, there are no kits, pipes, etc. that are bolt on.
Keith Wallace — 18 years ago
There is no governor on your moped, it is limited in speed by the exhaust, intake, carb, etc. There are also no performance parts designed for the qt50. Be happy that it runs smoothly, cause it ain't going any faster. I've heard most of them top out closer to 28 or 30mph, you may want to check your exhaust or ports for carbon buildup, that could be slowing you down.
Keith Wallace — 18 years ago
Do some searches for Fred's posts in the general forum for all dates, his pa50 runs up to about 50mph, and all he did was tweak what was there, and add a home-made exhaust.

Essentially, the reed valve controls the flow of fuel into the crankcase, minimizing the amount of wasted fuel. reeds "flutter" at idle and lower rpms to keep the amount of fuel in the crankcase matched more closely to the rate of burning.
Keith Wallace — 18 years ago
Reed valves also improve your gas mileage. You have to get a kit and intake that uses reed valves, so do your research before you buy a kit.Keith

Ummm....no. If not those sets, Tab has some of his magnum with the polini 70cc kit with reedvalves, a bigger carb and intake, and a performance exhuast. You can run it on standard 87 octane fuel, it doesn't increase the compression enough to warrant a higher octane, though iuf you want to run midgrade or premium, that's your choice, I suppose. (I have the same kit installed on my maxi
Keith Wallace — 18 years ago
yeah, it's the same. Check out this thread at mopedriders.orghttp://mopedriders.org/viewtopic.php?t=336&highlight=it lists tab's dyno results from his puch, and his aprillia too.

1-do a serach for all dates in the general forum, and look for references to Angelo, a fellow from sicily that equipped me with a performance pipe (leo vinci) and dellorto 15mm carb and intake for my old minarelli.2-go directly to the polini website and see if you can purchase it from them.3-find a dealer that stocks polini performance parts and find out if they can get it for you.Good luck!Keith

your cheapest bet is probably a gear ratio change, which would mean replacing the front or rear sprocket, or both. The lag in power happens because the pipe is designed to produce power at higher rpms, which your bike can't create until the top of it's powerband 9the two stroke slang term is 'getting on the pipe'). A stronger solution would be to add a displacement kit to you

No further, you've got it dead on. Most people recommend several things during break in:use non-synthetic oil for the first 300 miles. (synthetic is too slippery, will make the break-in process last longer).don't run hard or long for the first 300 miles, and don't open up full throttle for at least the first 100. I don't like to take a ped out for more than 10 miles at a tim

You would have to do trial and error. What size jet is in the carb right now? Any other mods to your maxi? I'd guess 2-3 jet sizes, but the only way to know is to buy them, get a new plug, and do a plug chop. (see fred's guide in the resources section for plug chop info). Why are you adding the hi-flow filter? I'm not sure it would add a noticable difference in performance by
