You shouldn't have to restrictions only happen on faster bikes 600cc onwards but if you talking about the inabilty to push your revs to the very max, I wouldn't do this unless you know what you doing, and by you asking this question, you don't know what u doing, this rev restriction is set in place for safety of your engine, rather than restricting speed.,,,

It`s ALREADY de-restricted!!! Restriction is only for keeping the 50cc models in the Moped category so some people whould not need an endorsement and not exceed 30mph,

SOURCE: any ideas how to de restrict hyosung gv650 or

The most common way is move the throttle cable from position one to position two. Check to see if this method will work for you by watching the throttle mechanism at the engine while an assistant turns the throttle (engine not running). When the assistant can turn the handle no farther, see if you can push the mechanism open farther with your finger or a screwdriver. If you can, then you will be able to derestrict the bike by repositioning the cable.

No they don't but they do make one for yours. Most kits are changed every 4 years, unless you can find and older one that matches exactly to yours.

A cold engine needs more fuel to run. The choke helps this by blocking the normal air flow.If you can get your hand over the carb intake try one finger at the time untill it will warm up. If it will just idle let it idle till it gets warm. The choke is so you can hope on and ride right away.

Is my 2005 qiangiang gmi 108 a 2 stroke or a 4 stroke


Hi, David engine design is very easy to identify:
TWO STROKE
1. Two strokes red line around 12,000-16,000 RPM.
2. A reed valve is in between the carburetor and cylinder head.
3. The exhaust has an expansion chamber.
4. The muffler has a small diameter tail pipe.
5. The exhaust has a high pitched Bap Bap sound.
6. Small scooters and small dirt bikes are generally 2 Stroke.
7. Older models had adjustable throttle actuated oil injection.
8. Older models had a premix ratio of 2 stroke oil and gas.
FOUR STROKE
1. Four strokes red line around 6,000-8,000 RPM.
2. Four strokes have camshafts and valves.
3. Mufflers have large diameter outlets.
4. The exhaust has low pitch deep rumble sound.
5. 350cc and larger engines are usually 4 strokes.
6. Four strokes have separate oil tanks that feed an oil pump.

How to tune / de-restrict a 2 stroke


2 strokes in lower ccs are usualy slow, so heres a list of things you can do to de-restrict and tune your 2 stroke.

1) Get a racing exhaust, Key part too most 2 strokes is a good exhaust, this will remove some restrictions. Gianelli, Big One, fmf and many others are available on ebay or your local bike shop.

2) Big Bore kit, adding a big bore kit can give up to 30% more performance, and will usualy de-restrict the bike. search ebay for (Bike Model) (year) Big Bore kit. it will come usualy with everything you need for the upgrade.

3) Carbon Reed Valves, are a key part too your acceleration, also removing the little cages that stop them opening all the way and replacing with big washers is another good step, make sure theres nothing for your reeds to nock on when removing the cage.

4) Boost Bottle, a boost bottle will help 2 strokes with no reed valves more then reeded bikes but will give alot more low and high end performace. search ebay for (bikes cc) boost bottle.

5) Jets, are a key thing when getting a bore kit or race exhaust. you MUST change the jets if you change exhaust, get bigger ones if you get an exhaust go a few sizes over and check the spark plug if its a brown tan/ grey collor you got it all right, if its black it means you have to much fuel so go smaller, and if its white it usualy means not enough fuel. you can buy jets from any motorcycle shop usualy around $1 a peice. you onyl need to change the Main jet.

6) Air Filter, you dont need it on most bikes but it could add extra acceleration, measure your carbeurator intake and search it on ebay for a K&N style filter, Power filter.

7) Restrictors in the intake, some 2 strokes have restrictors between the carb and the cylinder, it is key to remove these or drill them out to the size of the carb/ cylinder hole size.

8) Sprockets, if your lucky enough to have a chain and sprockets, its a nice trick to change sprockets on your bike.
For Top Speed - Bigger front sprocket & smaller rear sprocket
For Acceleration - Smaller front sprocket & bigger rear sprocket
by bigger or smaller i mean more or less teeth on the sprocket. if you go for speed your acceleration will lack and vice versa if you go for acceleration you will loose top speed.

9) Electical Restriction, Some bikes are restricted in the CDI, if yours does not want to reach a good RPM search up CDI, de-restriction. usualy it involves cutting a wire between the CDI and engine. and will unlock that slow engine into a screaming 2 stroke.


If you follow all these steps your 2 stroke will no longer be restricted and slow and will be the fastest arround.

What fuel type is used for saxonette luxus


Standard gas, it is powered by a 30cc Sachs engine. It is a two stroke, so oil has to be mixed with the gas. I can find if it is pre-mix or injected oil? You need to be very certain of this before you start it up.

The specs are here Sachs Saxonette Luxus 2007

With bike warm and choke off my 2002 crf450 pops on deacceleration. reves and runs exellent only on de aceeleration will it pop.


Popping during deceleration is unburned fuel igniting in the exhaust system. Four stroke dirt bikes are highly prone to this. However, you should be able to minimize the popping by restricting the air leaking into the exhaust. Replace the exhaust gasket in the head between the head and head pipe and the head pipe to the muffler. If there is no gasket between headpipe and muffler you may be able to improvise with a strip of fiberglass cloth

Is it neccessary to restrict 650 dragstar to 25kw


Orig power is 40 HP (29.2Kw) If that is required, it can be done by restricting top speed, exhaust pipe and/or chokeing the carb abilities but will take the fun out of riding big bikes..

How do i derestrict my lifan s-ray 50cc 4-stroke scooter please? forgot to add its a honda based engine and its a 59 plate thanks


Unless you find a small "restricting washer" between the head and the exhaust pipe...Then usually there is no easy means. In the past these "washers" were put in place to reduce performance, the idea was as the riders skills improve the washer can be removed. It also was a way for parents to keep their children from zooming flat out everywhere.

Red Warning Light is on!!! What does it mean?


Hi and welcome to FixYa,

On most vehicles, a red warning light indicates need for immediate attention. One area that this light would indicate would be oil level and/or oil pressure. On most bikes, the red light would show when IGN is first switched on telling the rider that the oil is not pumping. Once the engine has started this should go out indicating that the oil is circulating. In other bikes, the red indicator could represent the level of a 2T oil. In such instances, if it comes on with just switching on the IGN, then this indicates that there is little or no 2T oil in the reservoir. So this would be really be dependent on the make & model, whether a 4 stroke or a 2 stroke. Note: running a 2 stroke engine with little or no 2T oil in the fuel mix would result to burned pistons, rings and an overheated engine.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

General


i know you have to change the oil and oil filter but how often and is that the only thing different from maintance on a 2-stroke?. Im getting an 04 kx 250f any help would be great!The two most important aspects of four-stroke maintenance are frequent oil/filter changes and regular valve clearance checks/adjustments. And some four-strokes (RMZ450 for example) have a manual timing chain tensioner that must be regularly checked/adjusted. Everything else is exactly like a two-stroke.,,,
