    Hi i'm just wondering what the best performance parts are?
    I'm buying a 32 teeth sprocket because there is literally no hills around here,
    I'm also buying a racing carburetor. Is there anything else i should get? What exhaust is the best for top end speeds? Also wheres the best place for buying a high compression head? What else do you guys recommend?
    Thanks!!

    Carby and Sprocket I'm buying,

    A good spark plug first

    What would you recommend?

    From what I understand, hear, and have experienced, those are 2 good choices. I have also had a 36 tooth with holes in it for mounting to a disk brake hub, looked a little better machined than the eBay listing.

    Exhaust, doesn't matter, but does. Certain varieties of stock exhaust can be restrictive to gas escaping, others not at all, some loud, some not, pick what makes it run nice (remember the muffler is part of the cooling system, too cold can damage the cylinder, too hot same result. Remember as well that louder exhausts make you feel and appear faster than normal, even if it's only in our heads.

    I bought a tuned exhaust, worked great on my bike. Tuned is better described as an expansion chamber, and insert magic/science, and that chamber sends a shockwave back towards the engine, pushing clean, unburnt gas and air back to the engine, resulting in a more efficient engine. Some work, some don't, with the huge variety in riding style, types of engines, types of riding climate, something will work for somebody, and others won't.

    Research.

    High compression heads, I first owned and still operate a slant head design, I've seen a few types, mine has the best compression out of box, maybe a manufacturing defect made the volume of my head smaller than it should have been. Matt, of. Bicycle_motor_works on eBay, sells his custom machined hc head, on the bikes I've seen, cools nicely and performs well, another popular high compression head overheated the engine he used before the high compression.

    Wait for more replies before acting, perhaps a member has a very similar engine and set up to what you want and can have valuable input.

    Triple prong, hold up better to oily break in gas, one arm gets fouled, and the next takes over and helps burn off the bad stuff on the other 2.

    Grandpa had a nice Isuzu manual transmission pickup, ran beautifully but had a bad pinging problem, and just wasnt as powerful as grandpa remembered it being. We replaced all the plugs with triple prongs and he loved grabbing that stick afterwords until it had a severe engine failure after another engine went through it sideways...

    Iridium spark plug

    best mod you can do is take the crank out and balance it. (see my site for more info)

    Iridium, really...? As far as I can possibly tell, iridium plugs are a marketing gimmick unless the engine is quite litteraly built around the plug (which could very well be the case in a minority of ultra high performance machines,) course the multi prong plugs are likely a gimmick as well, but 3 prongs betters the chance of a successful ignition over a longer time. From what I hear manufacturers don't even recommend you adjust iridium plugs because it could damage them (like I said, engines built around plugs.)

    I second the crank balancing act 1, exit stage right. Lights camera action, what's going on here? Also exit stage right.

    Jag knows his stuff. Done as much or more research than any other person on this forum

    Iridium has never failed to give me a performance boost, no matter what engine I use them in.
    It's the only plug I recommend.

    I bet he does I just never noticed a difference performance wise, let's also note jag has converted the gas powered paperweights of the East into something that could be expected to be sold out of Switzerland, with help from automobile designers from Germany, and 2 not 1 but 2 nasa rocket engineers.. Of course his artwork benefits from a very high performance sparkplug (ehem did I mention engines being built around sparkplugs?) He frigging rebuilt them to higher standards than a Rolex watch.

    Yes, his engines perform well and so do his spark plugs, in a standard smokey the bear oil spitting oriental environmental disaster, I see no difference, nor do the other stock riders. 3 prongs, they hold up nicely though.

    Nice compliment but no - you've heard you can't make a silk purse out of a sows ear? These things will always be crude and rude.

    don't be so negative man.
    They can be greatly improved by anyone with a positive attitude and mechanical ability.

    Yes I heard the saying, too bad it was written before today's advanced technology. I mean today they are making ROBOT Stingray (the fish not the bike) skeletons from freaking gold then attaching thousands of HEART MUSCLE CELLS from RATS and wrapping it in silicone and making it swim with f***ing LASERS HOLY EFFING BAT CRAP BATMAN! THE FIRST REAL CYBORG IS THAT THING THAT KILLED THAT FAMOUS AUSTRALIAN GUY WHO LIKES ALIGATORS! No seriously they did that Google it.

    So it's likely safe to say that the technology exists to turn sow ears into silk purses, it's just currently easier and cheaper to use silk worms and those fancy weaving machines. But you just wait one day your childrens' CHILDRENS' CHILDREN'S WIVES WILL WANT SILK PURSES AND ALL THE WORMS WILL BE DEAD AND YOU'LL NEED TO RELY ON THE SWINE SOUND COLLECTION UNIT SILK TRANSFORMATION TECHNOLOGY TO RECREATE THAT SILKY SMOOTH EAR SKIN PURSES!! AND YOU NEVER THOUGHT YOUR GRANDMA'S FAKE GOLD TEETH COULD BE COMBINED WITH YOUR SISTERS PET RAT WITH THAT OLD TUBE OF BATHTUB SEALANT AND A FEW DOLLAR STORE LASERS TO CREATE A CYBORG OF DEATH!

    SO STICK THAT IN YOUR METAPHOR AND 2 SMOKE IT!

    What he said. Good engines exist, I've seen and ridden them

    Balancing is excellent. Iridium plug is excellent. Best bang for the buck bolt on, really feel it power, for a 2 stroke engine = expansion chamber

    Wtf I didnt mean to start a war with a comment.....I'm very disappointed in you guys.

    Back on track, I've tried the crap china spark plug you get with the motor, it does its job just not as well as one you could buy for about $3 bucks. Theres a whole thread on spark plugs and with my own experience ive tried the "performance" 3 prong plug from bikeberry and it provided faster start up and a tad smoother running than the china plug. I switched to an E3 diamond fire (similar to a 3 prong) and the bike started up almost as soon as i popped the clutch. It also ran smoother than the other two. The only downside was that the heat range may have been a tad too hot.

    Ive heard great results from an NGK BH6S(?) from people here, someone care to validate this?

    My opinion: (worth what you paid for it)

    For performance improvement gains most to least:
    1) Proper tuned pipe (including gasket matching)
    2) Curved CDI ignition, you will need it by now if you haven't detonated to death
    3) Properly chambered head (including proper squish gap)
    4) Porting (again, has to be done properly for the rpm range you want)
    5) Larger carb, finally
    6) Case stuffing, mainly helps bottom end
    7) Reed valve, but your going to need a big one by this point, the small bolt on stuff won't cut it.
    8) Stroking and boring, helps bottom end torque mainly, as long as it doesn't kill rpm
    9) Boost bottle if you take the time to tune it, otherwise don't bother.
    10) High octane fuel and the compression to use it, minor gain for the pain in the butt

    As far as bang for your buck:
    1) Rechambered head and gapped squish $0-$50 (might include a compression raise)
    2) Gasket matching $0-$5
    3) Porting, if you know what you are doing $0-$30
    4) Case stuffing $30
    5) Well designed pipe $40-$250
    6) Curved ignition, cuz you need it now $50-$100

    You are screaming along now, anything else is big bucks and small potatoes.

    I did a little test on sparkplugs a few weeks ago. Tried NGK and Champion and various heat ranges in a lightly modified motor.
    Have a look at the post if you can find it. The chinese 1 and 3 prong plugs did surprisingly well. Didn't try Iridium.
    I've used Iridium in my KTMs with no noticeable advantage, although they are specified for my snowmobile ($22 each!).

    Like I said twice before lol, jaguar rebuilds his engines either around the sparkplug, or he's just so damn good that they meet and exceed the specifications of racecar engines, which is why they CAN take advantage of the better plug, can lead a horse to water but can't make it drink... Give it enough steroids, though, and it will drink the river dry.
