    Hi, Everyone,

    I am new guy looking for my first gasbike.

    Actually, I made some research from the left hand side of sponsor links.

    Try to compare and figure out the pros and cons of different 66cc Bike Motor Kit.

    I compare one items on Ebay and one on gasbike.net shown as the link below, however, I don't know what's the buying criteria for 66cc bike motor kit



    I notice that the difference of these two products are the angles of spark plugs. Is there any special meaning for that design? Makes installation easier?

    Need some experts' feedback and opinions.

    I was going to buy a china kit on ebay just like just about any newbee to MB idea, but after reading bunch of horror stories on this forum about those, I decided to buy quality utility engine bolted to friction drive. Very easy and dependable setup.

    I am happy with my choice.

    If you are a type who likes to constantly play, tweek and fix things, you might be happy with HT kit.

    But if you want to built MB , then just ride it without much of problems along the way, then China kit is not for you.

    Read more posts regarding engines, drives, kits then make your own decision.

    Good luck and happy riding!

    No matter what the seller claims, I have found that most of the HT kits are about the same.

    not the same

    I started with the least expensive Ebay set up I could get and every part on it failed within about 600 miles. I then bought a zoom bike engine and it has worked flawlessly since then. I noticed that the better engine had larger head bolts and higher quality parts.

    even the gas tank on my cheep kit started to leek after awhile. Just because they have a similar design doesn't me their all alike. A old saying is" you get what you pay for" is out there for a reason.

    after reviewing many people's feedbacks, I am strat thinking about finding a gasbike with good quality with accepable price.

    Ebay seems a good place for us to compare the price online. However, I am more concern about the after-sale customer service. Just in case I damage anything accidiently.

    Generally speaking, what product specs will you guys take into consideration before purchasing a gasbike?

    Right now, I am discussing my choice with my brother about these two models shown below.

    "GRUBEE SkyHawk GT5 66cc/80cc"


    another one model is "Jet 66cc/80cc"


    Here is one thing I am kinda confused. GRUBEE SkyHawk GT5 66cc/80cc is like $20 more expensive than Jet 66cc/80cc but with less HP.

    Is that because of the brand? Any body wanna share comments? So that, I can make my final decision to purchase one for my brother's X'mas gift.

    Thanks for all your feedbacks and comments

    I have a stock Jet and it runs well. Have not had it long enough to say if it will last but it seems strong and smooth. This is my first MB so I really don't know nothin'

    Ya, some of my friends recommend me Jet as well.

    I guess because of their selling price and quality is comparetively good.

    Thanks for your opinion.

    Is it difficult to install these bike engine kit on your bike?

    Hopefully not....

    install info

    If I were you I would expect all of your hardware to get loose quick. I have had to doable up all of my mounting hardware so I could bind one nut against another. I would get myself a torc wrench. I am constantly checking my head bolts(every other day) to keep them from loosing up. I only set mine to 12 pounds but I would check with the forum to see what they recommend.

    My motor bicycle is my main form of transport here in the burbs, but I still don't take it for granted. Be aware of your ride and the environment. A cheep car is still over fifty times your size and nobody can ague with Newtonian physics.
    there is a thread dedicated to new users I would look it up.

    there, you got my two cents worth, good luck

    Thanks for your ideas, Mike.

    I will keep your advice in mind.

    After searching for tons of info online, I feel like more people prefer gasbike instead of electric bikes. Originally, I am thinking about getting a electric bikes.

    However, I prefer more power when I am riding.

    I guess gasbike will be a better choice for me.

    Also, Mike. A quick question here.

    If we have to check our bike hardwares every other day, what kind of tools I may need in order to make sure every pieces of my bike is on the right place?

    like the guy said before... all ht's are basically junk. Grubee is the best of the lower end manufacturers/importers. IN fact I wouldn't buy any other HT except one from grubee. You can get them through spookytooth or bikeberry.com. I believe the ones at bikeberry are on sale.

    having said that... if you want a good engine and well built/designed kit then staton or GEBE are the only way to go. They cost a little more up front but you get what you pay for.

    Bottom line is this... if you like to constantly tinker and adjust then buy an HT kit... if you just want something that will get 220 mpg, start every time, installs in under an hour with simple tools, and needs no adjustment... then go to golden eagle or staton.

    I'm one of the unusual builders. I have bought 4 engines..5 builds. The first from the one in my signature (stay away from them) and the other 3 from http://shop.ebay.com/powerkingshop/m.html?_nkw=&_armrs=1&_from=&_ipg=&_trksid=p4340 First one the CDI went out within 3 days, the seller so much told me to shove it up my azz. This last one of the last 3 the sprocket was warped (stamped out ****) and had me a new one in the mail within 2 days of e-Mail. Other then those two problems I have had not one problem from the OEM engine, not the first. I do quite a bit of inexpensive up grades myself before I crank them up for the first time. The last bike I built cost about $250.00 of which about $100.00 was for a NEW bike. These are cheap engines, don't expect much. My maintenance down time is at a bare minimum.

    4 engines 5 builts.... Is that what it takes to have one running and available most of the time?

    You probably spent much more than I did.

    But I decided to stay away from HT.

    I have 2 quality engines one 4 stroke, one 2 stroke, one driving kit, if I want to swap engine it takes 4 bolts, no maintenance beside ocassional oil change (4 stroke) I expect them engines to outlast me.

    1st build, the frame cracked where I drilled a hole

    2nd build, engine from 1st but down due to faulty aftermarket head gasket. In the picture below you will see a stock head gasket overlying the aftermarket gasket. The piston ate the gasket and ruined both the cylinder and piston/rings. The head is pitted. The supplier is aware but I've been so busy and I need to send a gasket and pictures.

    3rd build, engine 2, running strong and on the road.

    4th build, engine 3, running strong and on the road

    5th build, engine 4, running strong and on the road. ($250.00 w/new bike) This was the most expensive.
