First Build, have a few questions

[Wrinkley]

Hello Wrinkley...

I am new at this like you. I am chiming in only because you mentioned specifically the kit I used... from hel•io bikes.

I've been very happy with the engine thus far and have zero complaints with their kit.

There is one upgrade that was simply a requirement (for me) before I put my butt in the seat. I simply was not happy with either the 2-bolt ... or even the upgraded 4-bolt chain tensioner options that come with these kits. In my head I can see them getting loose and dropping right in to my spokes killing my rim (and potentially me along with it).

Not gunna happen.

My brother has used the spring tensioner that attaches to the engine... and he's also locked up his chain inside the sprocket area not ONCE, not TWICE, but THREE TIMES using that same tensioner (you'd think you'd learn, huh?)... again... not me.

I went with this tensioner and I HIGHLY RECOMMEND it...

(All the listings on Amazon appear to be the same part. This one happens to include two wheels instead of one ... same price ... why not?)



EDIT: Can anyone tell me why the IMG Width=xxx tag isn't working on this forum? This is an Xenforo forum, right? I know that width extension works on another Xenforo forum I frequent. I figured it was part of the stock software... maybe a mod? (EDIT #2: It seems it's a custom BBC code. One worthy of adding IMHO. The other forum actually simply replaced the stock IMG tag with it it seems as IMG WIDTH=200 works ...(for example). It really cleans up a site that has lots of embedded images. -soapbox

Thanks for your suggestion, I could definitely see the utility of that. I'll probably go with what comes with the kit just to start out so I can acclimate myself to the set up, but I could see that being one of the first upgrades that I do.

UPDATE

I ended up going with this engine, went with CDH because of all the positive reviews from this forum. Hopefully I didn't screw up too bad!

I would have done the same thing. Beware that it might be a little sluggish until it's broke in though with that 36 tooth sprocket.

I love the bike you picked, a common 5,6, or 7 speed with rim brakes, the most economical.

I lettered your questions;
A: mass produced so some are on backward, the pins for the rings go to the intake side, ignore any arrows or letters.
B: The most recommended plug is a NGK B6HS or Champ equivalent.
C: 80cc type kit will be fine and the most common to get parts for.
D: Have fun and take your time, if you run into any snafus, come back for issue solving.

Bikeberry is the least recommended, on this site anyway.

Check "Dealer Reviews" before purchasing.

If you really want to build a bike with a REAL motor that is a REAL pleasure to ride. The 139.00 motor you purchase anywhere is purely junk and a waste of money. You must realize that the actual cost of that motor before shipping from China is around $4.00 what do you get for your four dollars. The casting of the motors are made individually apart from one another one side of the bottom case is not made to the opposite side. Their specfications are way off. They don't even clean off the slag from the casting process. Start watching you tube video from smolik performance racing. These guys race their bikes on the professional race circuit. They build their own motors to very high tolerance. Yes they are not cheap. But you get what you pay for. I currently am running a Menirille vertical 70cc hybred manerriali dyno tested at 8.6 HP. The best thing I have ever done

You don't have to put a grand into a bike engine to have a fun bike, let alone the wait for those guys to get it to you. I put together quite a few $63 kits that are still on the road after 8 years, I don't have a dyno nor care what the hp is on them, it's the smiles per/mile that counts.

When a $1000 engine blows... you feel it (edit: Well... at least I do!)...

When a $150 China Doll engine blows... you order another one while you complain a little..

Looking at the frame of the bike, you'll need one of these to mount the motor.
Use a piece of inner tube wrapped around the tubes where the motor mounts.

My personal advice for a first time builder is get rid of the fenders. Latter on you can research how to reinforce them if you wish to put them back on.

You'll also need metric tools.

I use mine the other way but it won't fit with stock exhaust
