hey im a 16 year old and have a 1987 yz80 that has got some serious balls and i kinda wanna make em bigger if you no what i mean. I mean my bike hauls ass already and it flibs me over even when im riding at high speeds when i shift. But i wanna get some real power out of that bike any ideas on what i can do like litle stuf tuning and adjustments you no. edit: just so you all know i no alot about single cylinder motors as in how they work and a few whay to make em better so please no more retard comments like paint it red red bikes o faster...... and believe it or not ive have completely redesigned the engine i have a prototype design and am saving up money to make it a reality i dont wanna tell you to much cuz i dont wnt people stealing my idea but its a combination of a standard single piston motor and a rotary motor if you really wanna no more then ask and ill send you a pik of my design with some stuff obviously scratched out.

It sounds like your power band might be stretched. :msn-wink:

ducatilover suggested that nitrous would give my bike some extra speed, so it's sure to work for yours! also, there's this guy called 'shermin' who has made his bike go faster by drilling holes in the frame, to lighten it, might like to look him up.

Obviously you need to paint it red (if it isn't red already) And put some go quickly stripes on it (aka speed streaks I think).

If you're 16, may I suggest you try a 125. Much bettera balls for a man of your age.

nah i dont wanna bigger bike trust me i dont no what the hell the dude i bought it from did to it he said he used to race it anyway its frikken extremely powerful my uncle is a proffessional and well hes huge he weighs like 523 but hes not fat just tall and slightly chubby well he hopped on the bike thinkin it was nuthin and it flipped him over!!! so he got on again and sat so far up that if he went any further he would sit on the handlebars and he tried again well this time it ended up picking up up and making him do a weelie ll the way up my street. so i dont think bigger bike is nececary but i relly wanna put some serious power in it you no i mean deos anyone know any of the adjustment stuff like like spark gap oil vescosity and if i use a fatter spark plug wire could that help to.

Deffinitely get the fatter sprak plug wire. Also try to get a one piece coil and powerband off a PW50. It'll make it even frikken extremely powerfuller. Trust me.

Sigh. Someone joins the forum in hope of gaining further understanding of his bike, and more importantly how he can get more power, and all you guys can do is take the piss. No wonder motorcycling is dying before our very eyes, what with you lot not remembering what it was like to be 16 and ride a powerful bike for the first time.

So, ignore all the comments about Shervin, Nos, replacement powerbands etc, they are all just pulling your leg.

Now I'm no two stroke expert, but it sounds like this mighty 80cc beast already has been fettled somewhat, especially how it flipped your uncle, who lets not forget is a professional, and weighs 523. So with that in mind, I'd suggest you check the duration and lift of both the inlet and exhaust cams. Also degreeing the cams in is important, so don't forget that. Next would be checking the apex seals on the rotor. Are these carbon replacements or the factory ones? Once again, find out, you'll get a lot more power if they are carbon. Next to check would be how many windings there on the aperture. The more the better.

If you want to get really serious, look at reversing your cylinder. The factories all got in wrong back in the day (translation issue) and put the cylinders on in reverse. It's not an easy job, but there are huge gains to be made by correcting this. Think about it, exhaust at the back, inlet at the front.

There is a lot more that you can do of course, but these should be your starting points for a good base to big power. Let me know how you get on and if needed I could possibly recommend some more mods.

Rip the brakes off for a bit of weight reduction. It will go way harder then.

Another often overlooked mod that is perhaps the quickest, cheapest and most "instant gratification" thing you can do to enhance the size of a bikes balls is to swap the sprockets over. Take the front & mount it on the rear wheel & vice-versa.

If your uncle really does weigh 523, like you say, I'd hazard to guess the sprocket-swap may have already been done on your bike.

There is some pretty expensive mods described here but you could try the less expensive modest performance enhancing mods such as;

Replace the air in the tyres for helium, you have spoked wheels so you will have to remove the tyres first and cover the spoke adjusters with black duct tape (caution here don't use the grey, the pigment in the grey tape reacts with the helium. Many have come unstuck here excuse the pun). replace the tyres and re-inflate with the helium (obtainable from balloon shops). The more you put in the lighter the bike becomes and the faster it will go :yes:

Next; being a two stroke it will have transfer ports in the barrel (these transfer the fuel from the bottom of the engine to the top) usually one or two transfer ports are in low tune motors. A simple afternoons work with a dremel will add more (the more you add the more fuel will transfer, the more power the engine will make and the faster it will go. Before you do this pop your barrel into any motorbike shop and a service technician will happily show you where to make new transfer ports free of charge.

You will now have a much more powerful and lightweight bike so you need to look at the brakes. They will get hot hauling this beast down from the higher speed so will need cooling, The cables will expand as they get hot requiring more movement in the linkage for the same braking effort. Remove the inner wire and paint it with heat resistant paint used for exhausts and BBQ's and replace it when dry this will allow the heat to disperse more efficiently.

These few simple mods will take half a day to do and cost just a few dollars.

Helium??!! :gob: I'd recommend Nitrogen - It's a well known performance enhancer. I can supply tyre gas with 78% Nitrogen for only $5 per tyre. It's awesome!

I like this guy, :woohoo:
just remember, check everthing twice, walk away, have a bear, scratch ya balls then check it again,
the beer that is, ensue its empty.
Always on race day when your checking the bike before a race,
Don't get distracted by the pussy walking by, you might tighten the wrong knobb

Sorry Steve your quite right it does improve performance further.
However if cost wasn't a consideration I would fill the tyres with Iridium for its handling characteristics. The last quote I had was $30 a tyre!

Consider what you can do with the exhaust. This simple pipe performs two functions
1. removing waste gas behind the vehicle
2. removing noise (via the baffles)

Well it's only an 80cc so there's not going to be too much gas, no more than you're breathing from the bus in front. Plus the baffles as well as removing noise also strip some of the power. Get rid of the exhaust get rid of the power 'sap' and you get a great sound. Plus getting rid of the exhaust system you remove a hell of a lot of weight. It's a win win situation.

You might also consider getting rid of the carburettor for the same weight reduction reasons. The carb mixes fuel and air but for a simple engine how much mixing is actually required and as we know more petrol = more power = more speed (that's what we do when we twist the throttle. Much better if you just drag a pipe from the fuel tank to the inlet manifold and attach the throttle cable to the fuel on/off switch.

Hope this helps and I look forward to hearing you out on the roads

no believe it or not i got an aftermrket piston for a ttr 150 sent the motor out to get machined and it works really good the slightly bigger piston adds to the compression but because i upped the compression higher than it was indended to be im kinda scared of it exploding. lol

A rocket would be better that a bomb. Bombs just explode, rockets shoot along, then explode. Shoot along = more speed. This has been proven by myth busters I believe, strap a rocket to you or the bike and you should experience (although short lived) massive power gains. Don't worry about the extra weight of the rocket, it will be outweighed by the amazing improvement in power.

Take a dump (No1 and 2) and you'll probably shave 1.5kgs depending on how much you $hit.

Remember, 1 litre of water = 1 kg.

Speaking of shaving, shave all your hair off to take off some weight, and while your at it, eat less pies, or food altogether. Got any superfluous limbs or anything? That's sure to take off a fair bit of weight.
Less hair means less weight and less drag (Assuming you ride naked as would be expected if you want to cut down more weight) every little bit helps.

Try a fltaslide carb if it hasn't already got 1 fitted, deosn't really increase the power as much as peop[le might have you think but it gives it alot quicker....alot quicker:yes:

Iridium spark plug. Also, take the carb off and stick the fuel line directly into the intake manifold, carburettors are there purely to satisfy emissions requirements. You get twice the horsepower due to free flow of air and that cool whooshing induction noise, all your homies will think your bike has VTEC oi
