    I see no problems so far. You have a good start and will be rewarded for your efforts. Keep us posted on your progress. By the way, I like your color scheme. That should make a good looking bike.

    While I get mu dual pull handle, were should I mount my brake, front or rear?

    What grade hardware should I buy to replace my originals?

    Can I use regular black engine enamel to touch up some parts of my engine?

    Is it a good idea for me to remove the head and clean up/polish the combustion chamber?

    It is a slant head 68.5cc, what spark plug do you recommend?

    I would leave the engine alone till its broke in nice and easy. Run a few tanks of gas through it. The little engine will surprise you

    The cranny is my first build too.

    It wouldnt hurt to change out the hardware and get better quality studs. SBP Sells a hardware kit that replaces all the hardware or go to your local ace.

    I would defiantly just leave the head on and not worry about polishing the head.

    Update: Picked up a few things for the build.
    Bought Some locktite
    Bought some new black fuel line
    Bought the oldest looking fuel filter I could find
    Took the bag of nuts and bolts the kit brought and replaced all the loose hardware with grade 8 allen and locking nuts.
    Bought a NGK B7HS Spark Plug (Why is the gap on it smaller than my included plug?)

    Hi Caramanos, my build is a Cranbrook also.
    Like what you're doing so far.
    A lot of plugs come from the factory gapped to who-knows-what. Check your instruction book, if I remember right the gap should be set to .024 to .030 with a spark plug gauge. You can get one of those coin-shaped thingies at the auto store for around a buck.

    B7HS might be too cold. I had one of those lying around and ran it in my 48cc the other day, and it didn't seem to have the power that even the stock kit plug had. The kit plug was a nice light milk chocolate color after several miles, and the B7HS was a much lighter tan after a twenty minute run around the block. Of course, it was about 15 deg F outside, too.

    Until you get the dual pull handle, if you're only going to run one brake handle, I'd put it on the front, and make sure you're using it and your coaster to stop under normal conditions.

    I wouldn't worry about pulling the motor apart. Just make sure the head nuts are torqued properly (10 foot-lbs, 120 inch-lbs, I think? right?). If you don't go crazy with overtorquing the kit hardware, it shouldn't give you problems right away.

    The only hardware I'd advise to replace immediately is the nuts and bolts that hold the chain tensioner on. Get harder bolts and locknuts - anything the hardware store will have is fine. With only two bolts on the tensioner bracket, the bolts and/or nuts from the kit will strip before you get it on tight enough to stay in one place. Then you'll have the chain sliding off into the spokes, wrecking your wheel and possibly you.

    I picked the 7 plug because its never colder than 80 degrees here, usually around 90 during the day.

    Update:
    Made custom air filter housing
    Sealed gas tank with kreem
    Cant find enough lock nuts in the right size for the rear sprocket

    Hi, Welcome. If You Use Allen Bolts In Your Motor Mounts, Be Sure The Are Grabing As Many Threads As Possible. But Make Sure They Do Not Bottom Out Before They Are Tight. Studs Are Best For The Mounts. Many Have Trouble With The Mount Studs, Stripping, Breaking. Your Parts Are Looking Good. Good Luck. Ron .cvlt1

    Im done!!! My internet at home is out but im writing from work. Rode it last night finally after having replaced almost all of the kits and bikes hardware with grade 8 and lock nuts. Had to adjust the idle screw a little so it idles good. Chain is solid and didnt come off once (im guessing because we adjusted it for hours before riding). Also sealed the carb with silicone as recommended on the forum.

    Pictures will hopefully come soon, got it up to 20mph already. Thanks all, you guys have me addicted.

    Caraman, glad to hear your first build went off without too much of a hitch : ) Did you use the truck bed liner paint for the frame? If so that is a great idea, I might do that to my frame so I don't have to worry about scratches/mud haha. Good job man

    Caramanos, I have yet to get my motor, hopefully it comes today, but what all hardware did you replace. I'd like to get it ahead of time so it is ready for the install this weekend, or should I just wait until it gets here and go match up whatever hardware pack comes with the motor with new stuff at the hardware? What is the most important pieces to replace, the studs, intake, exhaust or head bolts and side cover hardware? This is my first build so I'd appreciate any help, I have a feeling this motor will be a little different than the 250 in my dirt bike haha. Thanks for any help ...
