    Ok so I have about 150 to upgrade my bike, it only ran for about 12 hours max so far. Then one day pop my spark plug flew out and its covered in gas dark black what does that mean? So after that I couldnt get it to run fully. And the carb was pouring out gas. So I was like DAM!! So I tried the next day to run it and now im hearing a loud spark So I thought it was the CDI so I orderd a brand new CDI from gasbike for about 25 dollars shipped it should be here tommorow. So until tommorow I wont know if it was the CDI or not. The bike has been sitting about 5 days and i turned off the fuel and everything. No fuel is coming from carb any more so I think it unflooded itself. But anyways I just orderd an RT carberator from datsdax, and I remembered my motor isnt propperly mounted its squishing the carberator. So I HAVE to order a front mount from SBP I was looking at one for $15 but I need to know the outer diameter of my down tube frame and idk it so Tommorow if my bike gets running im going to have to buy a caliper just to use it once to meausure my dam down frame. UGHHH so much to do! ok so I have about $90 left and I want to get some performance parts, I was looking at getting a expansion chamber but then I tohught I could wait till christmas for $80. So what I want to know is what upgrades should I get low cost but effective. I was looking at a manic mechanic Manic Mechanic Billet Intake Manifold BikeBerry.com intake. But does it fit? I heard it gives big performance for low cost. so yeah any suggestions on what to get? any comment is appreciated.Oh yeah I have a chinese 2 stroke 80cc . Sorry for long post just very excited to upgrade my happytime!.shft.

    First, I would break in your motor before trying to tune anything. This site is has a wealth of information on mostly every question you have about the HT, the google search is awesome and is your friend! :)

    From my research:

    1. UPGRADE YOUR BRAKES IF YOU'RE ONLY RUNNING A COASTER BRAKE
    2. See #1
    3. Purchase the hardware kit and head studs from SBP
    4. Replace all gaskets
    5. NGK6HS Spark plug
    6. Buy some high temp bearing grease, a cone wrench and service your wheel bearings (do this regularly)
    6. Port match (free if you have a file!)
    7. 41t or 36t sprocket depending on terrain and rider weight
    8. X-pipe

    No worries my friend, we all have to start somewhere! I found the following posts/forums extremely helpful:

    MotoredBikes.com: Motorized Bicycle Forum - View Single Post - Tips I've learned from many builds-great newbie read.

    Classic Instructions for Building and Repairing Motorized Bicycle Engine Kits - Motorized Bicycle: Engine Kit Forum

    I find as you tinker and continue to build more questions arise. Most everything you need to know about working on these engines are in these forums. Personally, I did most everything listed in that first thread that I had the tools and capability to do. If you're using a cruiser bike and need a custom front mount I can't say enough about Al.Fisherman. He made me a custom mount for $20 and it works great.

    For my MB specific parts, I like www.sickbikeparts.com, www.thatsdax.com and www.piratecycles1.com. Everything else I get at my local autozone or hardware store. I know it's exciting and you just want to ride, same thing happened to me, I'm glad I took my time though. If you're going to do it right, might as well start from the beginning..if you do your HT will thank you in the long run. :)

    theres so much to do After I read that!! Lots of small things to do but worth it in the long run. IM thinking about not buying so much into the upgrades anymore and get the neccesities done first. I think I will do that. One thing how the heck do I get the head gasket nut screws off? They are long acorn shaped and not much space to put a wrench in!!?

    Use a deep socket and ratchet.
    Be careful to not over torque them back on later, and ditch the acorn nuts. get standard nuts from a vendor or your local hardware store.

    10mm for 6mm studs

    13mm for 8mm studs

    edit: Do you have a socket set and a torque wrench? I definitely recommend using a torque wrench on the head studs and every other bolt as well. Here's a link to a cheap torque wrench that will work fine: http://www.harborfreight.com/3-8-eighth-inch-drive-click-stop-torque-wrench-807.html

    Also found an updated list from Al.Fisherman, check it out:

    Do not get wrapped around the axle about the cost of the tools. Firstly I PROMISE you that you will get your moneys worth out of the tools, and then some. (Plus you can get more that sufficient quality tools for our use at Harbor Freight. On line if not local.). Guessing torque = warped head. (Torque wrench at HF is $14.99) I am new to this as well, but have learned that the motors need only a reasonable amount of attention paid to them to keep running trouble free.

    1. Check chain tension before every ride. Tighten it right away if it needs it, NOT when (if) you get back.
    2. Check and tighten all bolts and nuts on the engine, mounts, and bike. (toss the fenders if you have them).
    3. Use quality fasteners, not the supplied junk.
    4. Use good gas and good oil (don't skimp to save $.25)

    That is pretty much it. Everything else out there are just neat add on's to make the bike sound, look, feel neat or gain a few MPH here or there.

    Stick with the basic bike and motor till it is broken in. THEN go an get the fun stuff.

    Thats my two cents worth.

    I haven't read through all the responses..

    Diameter of tube from circumference...

    Example 4: The circumference of a circle is 15.7 centimeters. What is the diameter?
    Solution:
    C equals Pi times d
    15.7 cm = 3.14 · d
    15.7 cm ÷ 3.14 = d
    d = 15.7 cm ÷ 3.14
    d = 5 cm

    Hi there Clashed. Do you have a welder or a buddy with one? The downtube on your cranbrook is 1 1/2 diameter. That motor mount you need is nothing but a muffler clamp with a piece of z metal on it. Just get a standard muffler clamp 1 1/2 and two small pieces of angle iron and drill the holes for the engine on one and the clamp on the other slide them against each other back to back till you get the height you need and weld them up. Don't kid yourself you are going to need wrenches and a socket set more than a few times. Maybe the sbp mount on the front will be just right if you lower the rear of the engine some. In anycase that carb needs to be close to level as you can make it. Sounds like the float might be stuck or its too out of level to work correctly. If its dumping raw gas into the crankcase your going to blow the seals at least. Take your time and get that motor set before you tear down the street. I have a cranbrook too although all I really wanted was the motor on it. It's going in a 48 schwinn that's waiting for wheels. Then I am feeding the cranny to my chop saw. The brakes suck for anything over about 6 miles an hour. But you got what you got so my upgrades would be a springer fork with the v brake bosses from pirate cycle and better rear wheel. See how this is going? I've added a hundred bucks to an 80 dollar bike. I know the wheel looks heavy duty but that hub is pretty cheap. Just be aware of it. And the 415 china chain is junk also. Get those front brakes set up first. I always said I'd rather have a car not run than one that wouldn't stop. Niagara cycle or bikepartsusa are good bike parts places. Scrap metal yards sometimes around here at least pile up old bikes in one spot. Yard sales and estate sales can be gold mines. I picked up my schwinn for 20 bucks.

    As far as the front mount, to install the engine properly, I feel you need to make one. Here is a front mount I made today for a member that is mounting a HT on a cruiser. The muffler clamp is not installed as when I took the picture I hadn't gone to town and bought it yet. Made today, mailed today.
