Reducing back pressure is usually a good thing on these engines but remember you need to up the main jet most likely since it can flow more air through the engine with added flow from openint up the exhaust.

Clean the spark plug real good with a wire brush and a solvent like spray carb cleaner or brake cleaner, dry it off, put it back in engine and then go for a couple mile road trip, after you get back let it sit for 10-15 minutes and then pull the plug out and look to see what color it is, if its very light tan or white looking its for sure you need a larger main jet.

Replaced the fuel line and spark plug with a ngk bp6hs and then took her on a test ride with no helmet, brakes, or shoes and couldnt get her slowed down enough turn back into my driveway so I decided it was better to go down in grass than asphalt so I tried going over the curb and flipped over the handlebars and landed on my face and trashed my neck pretty bad, now is one of the times I wish I had health insurance...


I have learned my lesson and she will be locked safely away in the garage until I put brakes on it and buy a helmet.

That reminds me of a friend, he was pulling his tractor behind his truck without trailer brakes and had someone pull out in front of him. He didn't wreck but came very close, ruined his bvd's I bet!

Come on bro....... these are exactly the kind of mishaps that have the potential to give motorized bikes a bad rap, common sense says if it has a motor and no brakes its a no go situation until it does.....!

Glad you weren't seriously injured and hope what is injured heals fast but we all better be thinking about the big picture and not taking risk like that for multiple reasons, first it aint worth loosing life and or limb over and second one bad accident may be all it takes for some nut job with some pull and money in the area to mount a campaign against people having a motorized bike on the public roadways....... lots of people now days just itching for something to make themselves famous with......

Again hope you heal quick and good..... and as you said..... keep that's dang bike as something only to look at until you make sure its safe.....!

The first thing I do to any vehicle or motorcycle is check or go through the brakes, my son once asked me why. I told him " it don't have to run but it has to stop"!

I know im an idiot but I never left the subdivision and only two people saw it, one was a middle aged woman who didnt even offer to help and the other was a surveyor who wanted to buy the bike.


I found a front and back set of caliper brakes including levers, cables, calipers, and pads for $25 a few days ago but cant find them now, does anybody know where I can find a deal like that? If I can find them ill order them tonight but I cant afford more than that for a few more weeks so anything more expensive is out of the question

'' one was a middle aged woman who didnt even offer to help ''....dude.
You're lucky she didn't come horselaugh you as you lay writhing in pain.
I would have.
You should find a cheap or junked parts bike for your brakes. Cheaper than buying new.

Those are side pull that mount in the fender mounting hole, if you need v-brakes just search on eBay.

Shoot, I cringed reading that spill story. I've treated folks with head and neck injuries. They can change your life quickly to a no-fun option. Picture being fed with a tube.
I'm sure it's sitting there all tempting to ride as it's new etc, but don't do it without the full setup including a lid!
Now I can sleep after writing that.
