Ha. Doubt my truck is too accurate any more. I put different rims, tires, changed the suspension all around and screwed with just about everything I could within my capabilities, lol. Its a bit of a sleeper I guess. All my buddies have seen some of the hidden upgrades and I helped them do some of it to their rigs. Its become one of those things that I can't ever sell due to the chunk of time, blood, sweat ect. that I will never get what it's worth. Plus I can admit I wouldn't mind befriending the cop on my block. Lol. He seems cool. I ported the extra 1 pc head. Took my sweet time on it and I believe it will outperform the 1st. Kind of odd this one doesn't have the decomp notch that the other has. No I didn't research or use a degree wheel. I will get there eventually.

Thats because if you measure it-it appears to me it could be a 40mm/43cc or 42.5mm/46cc cylinder..How many screws hold the intake to the cylinder on it?

If it is 44mm and notchless that would be the most awesome seller to keep note of or buy another asap as that would be a unicorn in the pb world.......

You dont have to use a degree wheel yet...You can experiment around a lil with different porting technics...You only need the wheel when you want every lil ounce of power to shine through by taking the tool engine and turning it into a full blown racing engine with a specially made tuned pipe thats tuned and designed to the porting.Without a degree wheel you're at a stalemate on the pipe....



My 2010 1500 quad cab has a 6" lift and 35" tires with 250 extra hp and my 08 2500 series has 3500 series heavy duty axles in it with larger tires and about 300 extra hp....Both with gear changes to maximize torque...

Both have 100% accurate speedometers and do you know how?..My power programmer...It allows you to change the gear ratio and the tire size to keep speedometer accuracy……...

Nice. I wonder if that is available for my tacoma? More than likely it is and even more likely, illegal in ca. Smog laws are fairly restrictive here. I have printed a few wheels and started reading into proper use. I just laminated one and another I affixed to a piece of lexan. There are two bolts for intake and two dimples where it looks like two bolts would be if drilled/tapped. I of course will believe you on the mislabeled cc of the jug as I don't buy the unicorn story, lol. Looking at all the pics of your engines has really peaked my interest into auto cdi, custom 2 piece head design and execution. In your opinion is it possible for myself to cut the head off and get a cap off say ebay? I read you used a fine tooth hacksaw, file and oilstone. And finally last question (at the moment) I should follow break in procedure for this new top end even though I ported first correct? It will be a while before I get to that however. I still have yet to polish, blueprint bottom to case, ect. Sorry if I used the wrong term at any point. I never really got into the lingo of some of this until I got introduced to forums, which hasn't been long at all.

Hey cam what program do you use there for the exhaust Calculate?

Something seems to be wrong, however, according to your calculation, the overflows are open 240 °

Re: New to little bikes.

ive got about 7 different pipe calculation programs, this is a copy/paste from a txt file ive had for about 9years, so im not sure if the links are still live, but i got the programs via this first one... (the link is dead but the page/forum is still there... the links are sure to be buried in there somewhere on a new page.)

A big collection of free(small)software

Port Timing calculators - Lambretta Images Archive

TorqSoft - Reed Petal Design - Calculation Tool
Only reed petal calculator I've found. Good guidline for syncing natural frequency with rpm.

Re: New to little bikes.

That's what I did, hacksaw, I believe 5 fins down, then break off the 6 fins, that gives you space to form the ring for the Cag head. I used a new grinding wheel on my 8" bench grinder to rough form the compression ring on top the cyld, then Dremel, files, sandpaper etc. I have a small surface plane and sandpaper, you can use glass and lay it flat. The top of the ring has to be flat to seal the round copper head gasket. Here is a Cag cut cyld from Sam, Boosted306.

Sweet thanks epr! I might try it out and see if I can make my own two piece head. Worst case scenario is I waste 30 bucks on a jug. Some of cams engines are stuck in my head and I love it when I frankenstein something and someone else looks at it and says what the...? Just whether I can do it successfully is the question. Lol

Re: New to little bikes.

The other main thing is, your case/cyld mount threads are a little wider so on the Cag round alum hp head, you have to move all 4 head slots out about .070" to mount your alum head on the piston port engine with the long bolts that comes with the Cag head kits. I have seen the round alloy heads alone for $20.

So cam was right which we already knew. That jug is not a 49cc so I contacted the seller and raised he, ll about it and threatened to complain to ebay, leave bad feedback and whatnot and low and behold they not only refunded me the dough but sent another one free. Whoowho! Now I can actually use a degree wheel and try to get calculations right. Fingers crossed. I think I will lop the head off this one and make a two piece. Or try anyway... Epr you said an x6 would fit as far as front forks, or x7?

2 stroke Wizard.....Like I said in previous also in numerous threads that state tool based engines aren't as technical as European built ones and all arent built precise like european engines are and even though they operate on the same principals there's different ideals in the purpose in which they are built and casted for....

There's a wide range of different Chinese engines to experiment with where you'll soon learn that the rules of building performance oriented two strokers is in a world of its own against even Japanese built motorbike engines...…


We didn't have Polini in 1983 but we did have IAME and besides theyre only 39-50cc...We modified 80 and 100cc 2 stroker Chainsaw engines that pushed 20-35hp and propelled jr karts to 70-85 mph....

X6 and X8 4 stroke models.They have a necktube similar to a BMX bike with same circular caged roller bearings

X7s use wheel bearings and a 10mm steering shaft.

As far as the engine it shouldn't be too bad...You are definately capable so I feel confident in you completing the task sucesssfully..

I found something new today. The gearbox has been fine but the little section that reverses rotation has been spitting up oil out of the fill bolt ever since I changed it. So I pulled it out and pulled the one on the gearbox itself. When you look at them side by side the vent hole is higher on one in comparison to the other. So I switched them out and no more oil spit. Boy thats a duh moment for me. Lol Thanks guys I will report back when I'm done, fingers crossed haha

Hacksaws......These are a few of the ones I use.....Sure you could use a saws-all but you can lose control quite easily or even use a lathe but that adds to the bottomline...…



Heres what I do to make the cut successful....

I use the bottom of the cooling fin as a guide

I use a really really fine hacksaw blade...…I believe its like 1/16" thick and 32tth per inch bi-metal blade....

I don't make the cut straight through straight off.....I cut straight through the rib that connects all the cooling fins then I kinda go around and around at first to get a good solid guide line then I make my crosscut...…….



I also spray the blade and inside the cylinder with WD-40 too..



These are the worst bottomends….LOL

Heres a great solution....Take the top bolt out..Open the sidecase and put a rag on top of the chain to collect the drill cuttings ..drill and tap the top hole for a 1/8" NPT fitting...

Put a brass barbed fitting with a short piece of rubber hose..You can make a topper by slitting a screw in half and slipping it on on top or getting one of them vent tops they use for pitbike fuelcaps...

Forks for 4 stroke X6/X8 and lower triple clamp..You may be able to drill the topclamp / bottomclamp holes to 26mm's to save a lil $$$..Also if you happen to find the top clamp it will be about $10 cheaper than the bottomclamp with steeringpost.

If you really want them act fast because as you can see theres 2 pair left...

One thing to know is they will need to be modified aswell….I use motor honey or lucas Oil stabilizer in my 4 stroke forks mixed with a lil Factory Connection FF5 fork oil.......

The Chinese just put mineral oil that's thin as water and those forks have very loose valving...…….

Re: New to little bikes.

Next you'll need a nice 3 way adjustable mountainbike shock with thicker 750lb spring for the rear....

One thing to note is something youd never consider when summing up the feel of the rear of an X1 X2 X6 & X8....


If you remove the rear swingarm youll notice that the swingarm tube just simply rubs on the sides of the frame also inside the tube itself and the fit is quite sloppy and gives a lot of negative feedback to the rider while riding...

You can only tighten the swingarm bolt only so much before it starts counteracting against the suspension making the ride even harder..

What I do to my X1 parkinglot racers is add roller bearings on the sides and whats funny is I use the front fork tube bottoms to make the bearing holder to weld inside both frame legs..


Then I cut the swingarm end tubes down so they fit in between the roller bearings...

I also drill out the swingarm tube and line it with a nylon plastic tube with a 10mm inside diameter to match the swingarm bolt..

I lube the bolt liberally with silicone vacuum grease...……

Even with the stock modded pogostick spring its a huge overall improvement in ride feel aswell as handling.....

I have yet another random question for you guys. Is it terribly difficult to ditch the housing for the elec start? I already gutted it and used the center of the armature to reattach the starter pawl but I'd like to remove it and mate the pull start housing to the engine. I know if I do it then it will be difficult to use if I ever want to use the plastics again. What do you guys think, do it or leave it. Still haven't cut the new jug apart yet. My wife has been putting me to work on the house again but my mind has been on the bike the whole time, lol.

Its not terribly difficult...its just a small PITA.If you gutted it totally id leave it...If the itch ever comes to reinstalling an e-starter again atleast it will be an easy task..
