The big bore kit is pretty easy. It is actually pretty basic. If you are buying a complete kit it should come with a spec sheet that will give you clearances and so forth. Make sure you gap the rings. I believe the gap should be .002" per inch of bore. If you are running a super hi-lift cam then you will want to check the piston to valve clearance and also the check for valve spring coil bind.
Good luck and let me know if you have any further questions.

sounds like a head gasket, get your head bolts re torgued before the problem becomes worse. it might be to late now, might have to replace the gasket to be sure.

No other gear set available to my knowledge. The correct set of gears should be able to handle an extra 50cc. The head gasket and cylinder gasket should also be the same. If they arn't, the larger gaskets would come with the kit.

I have a hawk 250cc Chinese dirt bike with 80 mph on the speedometer but I only can get it to 50mph what could I do to get it to 80mph


Hi, Maurice that is the average top speed of a 250cc 4 stroke engine but depending on how fat your wallet is there are a few things you can do to increase speed: 1. Adjust throttle cable so carburetor slide is completely up. 2. Experiment with larger carburetor main jets. 3. Go up 1 tooth on your front sprocket or down 2-3 on the rear. 4. Adapt/fabricate a K&N high flow air filter kit.
5. Performance camshaft if available. 6. Performance exhaust system. 7. Big bore cylinder kit. I know this is a brand X scooter but if you spend enough time on the web and know where to look by googling and visiting dirt bike forums you may not get what you want but you can always get what you need. Good luck and have a nice day.

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.

Wide open throttle there is no rpm like ignition problems has a9 cam big bore kit with the big valves high-performance plug coil and cd put 24mm manual carb jetted


Hi, Larry and the usual suspects are:
1. Severely drained or faulty battery.
2. Faulty regulator/rectifier or high output coil.
3. Faulty power valve, solenoid or installation.
4. Clogged air filter or exhaust.
5. Cracked or incorrect float level.
6. Float needle is not seating.
7. Faulty reed valve.
Good luck and have a nice day.

I have a klx 250s 2009 model and was thinking about getting a new needle and slide put in plus a 300 big bore kit will this give it more get up and go...


The 300 kit should produce more power, and you may need to rejet the carby to match the 300 kit
A good after market muffler also increases power
A needle and slide will not produce more power, unless the current ones are very worn and supplying the incorrect mixture.

boring over increases power but reduces durability. If you're looking to race, it's good but if you just want a reliable toy, I'd get a stock bike

I want to significantly power up my 1996 Yamaha Royal Star 1300. I've been told that putting racing cams, dual valve springs, a performance kit should do the trick. I'm obviously not a builder. What...


Race cams do increase power, but reduce mileage and don't idle as well. Dual springs prevent float at high RPM, but it is not clear you want to rev that high as they do in racing. By performance kit, I assume the idea would be to cause ignition timing to be advanced more when accelerating. This will take advantage of the valve opening overlap from the race cams, but may require premium gasoline to prevent pre-ignition.
Technically I think you can do this without even removing the head. But it may be easier to remove it. And then it may be cheaper just to go with a larger bore or larger valves. If you don't have the tools for compressing the springs, then you will have to take it in anyway, in which case you can get their opinion. But it is within the capabilities of most home mechanics that understand how to replace a timing chain. You have to keep the crank and cam in correct synchronization. If you don't know what I mean, then don't try it without reading up on camshaft timing.

Tt600 performance parts?


There are no mass-produced engine parts for the 600/650cc, so you'd be looking at custom built parts. There are ecm programs (e.g. power commander and tuneboy) that will help with power as will aftermarket mufflers.
