just started a new 4 stroke build

Looks like you have all the basics - I'll bet if I was starting on a new project I'd have a batch of parts that appear similar to yours, including the 4-stroke.
Looking forward to future photos.

If you don't mind would you tell us which 4-stroke kit you decided on and why? I'm new and still working out the decision making process of the difference in kits offered. 4G -7G and soon 10G, so many to choose from.

Thanks for the information on your decision making process, being a newbie it is really easy to not make the best choices. I bought a Firmstrong Chief bike for my first 4-stroke build but now find myself needing to fabricate an engine mount.

This is the bike

I wanted to mount the engine right above the chainguard and the span is approx 15".

I bought the same kit you did for the same reasons you did, plus it is closer to home than everyone else.

I also picked up http://www.kingsmotorbikes.com/44-tooth-cnc-sprocket-adapter.html

That purchase was based entirely on price, when I ordered it they were 25% off and free shipping on the entire order. I'm hoping the 44 tooth will work ok.

Call Bicycle-Engines and see if they will help you out. I'm hoping after paying 3 bills for a kit they will provide some support for you.

Nice build!

You can really wake up it's performance with the following:

Pull off the box exhaust and put a real pipe on, a 2-stroke pipe can be made to work.

Get an NGK 7544 (CR7HIX) Iridium spark plug and pull out the CCV hose from the air filter and put it in a catch can for the crank case waste.

The 4G transfer case was a good choice.
Looks like the 100T, is yours a freewheel 100T pulley or freewheel sprocket?

A shift kit is pretty much a must for me with the HS 142's and they sure make a difference.

SickBikeParts make a nice shift kit for the 142/4G combo.
Their new base design is spot on for motor mounts now too.

Also note you don't have to be a slave to the 4G motor mount holes.
I didn't want to put a super wide crank in this fat tire so I oriented the 4G so the bottom of the cover was just above the left pedal.



With small slots for the mount bolt holes you can tension your left side JS chain by orienting the 4G.
Actually that is a new 10G but the same base, just a different output shaft and 100T freewheel design.

You can also handle right side chain tension pretty easy with your kits chain tension wheel.

Just drill a slot in the base and put it there.



The fat tire was too cramped for the stock carb and air cleaner so I put an NT on a Z intake on it and it runs great.

When you get to wanting to make it a shifter get ahold of me.
I have some special parts coming and working on a new 4-stroke shifting system based on what you already have.

In short a jackshaft, without the extra shaft, sprocket or chain.

its a free wheel sprocket and i just order a http://www.bicycle-engines.com/Standard-One-Piece-Muffler.html muffler and i plan on picking up a new spark plug tomorrow, and i have plans on picking up the jack shaft kit when my funds permit it

Yep, 'when funds permit', that's a bummer for most.
Gears change everything though, it's not cheap or easy to pull off, but worth if you can, even a simple 3-speed which I like best anyway.
