Nice score...You have an MT-A2 cag and a 49cc cateye..........I had that same cag frame..it didnt feel too sfe so i remodeled it a bit ........have fun with the builds,,,,,,,

Nice, I'm don't really have any experience with porting so ill have to find a tutorial or something. Any idea on what kind of boost in performance I'm looking with the 49cc head kit?Nice score. Your have a 43cc and 49cc Cag head kit. Raise and widen the exh port on the inside and leave the base gasket out and use Yamabond, it will raise your compression a whole lot. For $30 shipped your can get a full circle racing crank in 10 or 12mm to fit your piston pin.
The perf you get depends on where the cylinder was made and the finished squish and compression ratio...........The one 3 port cylinder you showed has wider transfer ports than the other...the wider one is the one to start out with...Nice, I'm don't really have any experience with porting so ill have to find a tutorial or something.

Well! what is it?Theres a basic rule to the basic mods and if carried out to the TEE can yield great power aswell as put a smile on the face almost every ride..........
Something like this idea I first had for my stand-up scooter..?Question for cam or epr, have you ever retrofitted one of these with a cag engine? Just wondering how you could accommodate for the fact the gears on the right side.
The carb throttle mech is broken on the piston port, i have another pumper carb at my parents place but i dont go back till the 6th and i was hoping to have it running before then.
And i kinda wanna install the big bore and run that puppy.
Cateyes have a 2pc engine mount thats bolted to the frame plate...thats how you adjust the tension in the front chain for the jackshaft and the engine.............If you run a 5 to1 reverse reduction transmission, and run the engine backwards, like the twin engine bike I am building.
The Cag engine is no better than a piston port, and it's alot of work, would have to cut off the Zenoah engine mount and weld a Cag eng. mount, weld a bracket for a brake caliper on the otherside.
You have a 5:1 reverse reduction box already on your Cateye...........Flipm the cag engine backwards,,bolt it up to the trans,,Bolt it down straight,,hook it up and give it a whirl.........No clue where to get a 5:1 reverse reduction box...
Probably going to end up waiting till i get the other carb from my place.
The crank in this engine is covered in yellow gunked up gasoline whats best to clean it out with? Gas or kerosene?
All the engine flanges at the bell housings are the same size and the bellhousings are interchangeable........Ive run so many versions and combos I dont even know where to start to show that even though tehyre two diff engines theyre quite the same in certain ways..............I was looking at it but will it bolt up? It didnt look like it would but then again i am tired as hell atm.
The arrow points towards the exhaust port on reeded engines............So i decided to clean up the cag engine and get the new bore installed. Found a broken petcock mount (luckily i got a brand new carb) and then i managed to break a piston ring well putting them on...
Hopefully the small engine repair shop has piston rings the right size...
also what side does the arrow point to again?
