Finally i got the main jet kit from battlescooter, i am impress it is great and the t-shirt is wonderful, so i was able to finish my air intake, first a list of supplies 1 5/8 mandrel bent exhaust j-pipe (you can get them from jegs or summit for about 13 dollars) k&n type fabric air filter with a 1 11/16 flange (you can get them from any go kart part supplier for about 10 dollars) Any radiator hose with an inside diameter of 1 5/8 Flat piece of sheet metal for the bracket  just cut two pieces so that the straigth tube is 11.5 cm (4 1/2 inches)and a section of the bent cut at a 45 degree angle, in one of them you need to solder or epoxy a couple of fittings for the hoses, i fabricated them out of old gas filters, cut two small section of the coolant hose so you could attach them together and to the carburator  the bracket was kind of tricky but after bending some cardboard and cutting and trimming untill i was satisfied with the fit i made a template so i could transfer it to a piece of sheet metal, if you have any problems maybe later i will post the template, i also had to trim the rear fender so it will clear the filter  I had to rejet the carb to a 90 main jet to get the motor to run smooth, boy i am happy, it picks up speed a lot faster and the sound alone is great, now i need to get one of ruckass mufflers and this ruckus will be perfect, any way a before and after pictures   |

I really want to do this mod but am hesitant about taking the carb. off and dealing with all that mess. I really want an individual air pod filter though, I put those on my motorcycle and I think they look soooooo much better than the stock box. Nice job too on that homemade bracket, I wish I was good at working with metal.

That bracket is the part of that kit that might be hard for many Ruckus owners to make. You might wanna consider making and selling a few. The filters etc can be gotten anywhere.
As for taking the carb off. Once you do it, you'll see it aint that much trouble. Just a lot of screws taking off the seat, foot plate, and taking the carb apart. I'm going to cut that plastic plate in half, so I can leave the foot part on when I want to get at the motor.

Yeah, cutting it would be nice, I was thinking about getting one of those frame braces though. I think it's better though with your legs inline with the bars instead of out on the pegs for aerodynamic reasons.

Yeah for aerodynamics, legs out onthe pegs does add a bit of drag but its nice having them so you can switch up your stance now and again. I like being able to lean forward with my feet on the pegs. I find its not as hard on the stomach. My pegs are rusting though which is kinda pissing me off as they were kinda spensive!

I have find out that with this intake taking the carb out is much easier, becouse removing the air box was a pain in the neck, but you just need to remove the seat and all 6 mm bolts in the floorboard, raising up the floor and the carb is just there, i keep the water cooling lines bypassed mainwhile i work on a satisfactory jet size, so removing it was easier, just the fuel line the cable and the electrical connections, the pick up is a lot better but terminal speed remains the same, however is nice to finally move from the light with the same speed as the rest of the traffic. Hey ruckass where did you get your muffler and who makes it, i want to fabricate an exhaust system and that muffler looks a lot better than the go kart one i was looking at. fabricating the bracket is not that hard figuring out the shape was the hard part, becouse it has to clear the spring and hold the mudguard, the one they sell at battlescooter is just a bracket to hold the mudguard, becouse the filters are before the spring. I will take picture of the template with measurements and post them on the wekend.  |

The muffler is made by a friend in Taiwan and imported to Vancouver. Its made for a 125cc 4 stroke but works great on my 50cc. The only prob is, it needs a pipe made exactly like the stock one. The pipe that came with it was too large in diameter and did not curve in the correct way to wrap around the radiator etc. It had to be cut and re-welded to work properly. If you know of anyone who can make a stock pipe replica, it would be a smokin system (no pun intended). I'll try and get some more close up pics of the connection from muffler to pipe.
I don't know how much he sells them for as I got it at cost. I'm kind testing it for him. If you want to contact him his name is Wayne and he can tell you more about it. His e-mail is scooter@jiangwayne.com By the way, they come in a few different colours. Tell him i sent you.

I shorten the pipe were the filter is by 3/4 of an inch to make it closer to the spring and bracket, to avoid putting to much stress in the hoses, here is a final picture  I think it looks better, What do you think? |

 Thanks, i am planing to make a box to enclose the filter to protect it from the rain, a concern here in south Florida. I was hoping for some feed back.

I noticed you kept those two fittings on the intake. Those extra emission hoses. If I remember right, the battlescooter site tells you how to re-route all that doesn't it. Basically, if you wanted to just smack a filter right on the carb, couldn't you just plug up all that extra stuff?

See this is what i mean for feedback, those two hose are one for carb breather and the other for the pcv system, both need filtered air, the one they sell at battlescooter has small breather filters for these two hoses, if you look at the pictures you will notice three filters all group together on the side of the engine, i wanted to avoid that porcupine look so i did it this way, one big filter and two fittings for those hoses, the one you can get rid off is the pair injection, you just need to cap off the pair valve and the vacuum supply line, i decided to keep it so i just put a foam at the end of the hose by the gas tank.
If you decide to install a filter at the end of the carb you will need to install two small filters, one at the carb
and the other at the head (actually valve cover) for the pcv system.
Is allways a good idea to have a good supply of filtered air before the carb for those times when you snap the throttle so you do not starve the engine of clean air, therefore is a good idea to have the filter away from the carb (or throttle plate) not right at the end of the carb,
any comments will be apreciated.

I just bought a K&N filter, that is lots like that. Did you connect all the little hoses just directly to the intake? What diameter is the whole on the end of the air filter? The one on the K&N filter is pretty darn small, I may want to drill it out. Here are some pics:   |

My intake on my K&N filter is much larger than that. Maybe 1 or 1.5 inches in diameter. I connected one of the hoses and plugged the PAIR (PAR) valve. So I only have two filters.

Well I'll be able to drill it out to make it about an inch. Right now it is the same size as the intake on the stock exhaust. Hmm, I wonder if it would need jetted since its the same size. I imagine so. I'll drill it out larger and then re-jet my carb. It should flow well! This K&N filter is made for engines smaller than 250cc

Mine works great, though I do worry about water getting inside it when it rains. But the oil its soaked in should keep most moisture out....I hope.

 i can see my pictures anymore Ok i bought my filter from a go kart place call American Power Sports its web site is www.apskarting.com and is a K&N type filter part AP1636 and is a 3x4 filter with a 1 and 11/16 flange, they do have real K&N filters of the same size but are about 4 times as much. The one you have is a breather type so it does not have a flange, you will have to modified it, if you plan to reuse the rubber intake pipe, just cut untill you can fit it in, now the factory intake has three vacuum lines, one is the vent for the carburator (you have to keep it) one is for the pcv system (you also need to keep this) and the other is just a loop for the PAIR (you can just plug one connector at the head and also a small vacuum hose in the intake between the carb and the head) but i decided to keep it, so i hook the first two hoses to two fittings i welded to my intake hose, you will need to cap these two hoses with small breather filters or hook both of them to a vacuum t and install one filter for both of them  I have to find a way to post pictures so i can explain this better
