74 honda cb200 kart

[superballskart]

I have a few questions about how to mount the engine in my frame which I built myself and still is not finished but idk if I should set the motor real low in the frame to line up with the axle in pillow block bearings or if I should just get the cassette bearings and mount my axle higher its all up for debate I'm not doing suspension either I'm relying on 22x11 and 20x7 tires

Will be adding more pics later everything else is in my basement but its pretty much all new part except front tires the motor was rebuild with +1mm pistons and when I got it back I had to rejet it and get new air filters but now the motor runs amazing

Looks good.

A "cassette" type and pillow blocks are the same, except PB are self-aligning. The regular bearings need a housing for them to sit in(ie. make or buy them if you can).

I'm just worried about my sprockets lining up ..I'm not running a jackshaft my axle will be behind the engine and idk what would be best thinking just set the engine deeper in the frame so everything lines up and it lowers the center of gravity since my kart will be sitting fairly high

But if I use cassette type it will lower my rear which would probably be better and then still set the engine deeper in the frame

Setting the engine lower is a good idea for the reasons you mentioned however, you can only go so low before you start losing ground clearance; as long as the lowerst point of the engine is higher than the axle, you'll be golden...

It makes very little difference (as far as alignment) whether you use pillow blocks or cassettes, it all depends on where you mount them to the frame...

OK thank for your input and helping me navigate this site I read a lot on here but this is my first actual post

 

[OzFab]

Technically, that ^^ was your 5th

That's why we're here Ask all the questions you need...

Welcome! What gear ratio are you thinking of running? What engine are you using? Are you going to use a centrifugal clutch ot torque converter?

 

[thepattonman]

If I am reading this correctly, you are wanting to use a CB 200 from a 1974 motorcycle and install it into a kart frame which you fabricated?? If yes, let me know and I will walk you thru the next steps.

 

[superballskart]

Your right pattonman but pretty much I'm stumped on how to make my engine mounts I have my original rear motor mount I planned to incorporate in it

 

[thepattonman]

OK if you have seen my kart then you know I'm pretty good at installing motorcycle engines into karts. Here is a couple tips to help you out. By the size tires you have you are not going to have to worry to much about ground clearance. I would suggest that you install some cross members front and rear. In the engineering world its known as triangular bracing. Basically you need to support the lateral forces that your kart will produce. Put a set between the front two lateral bars. ( left to right ) and two along the two back corners but keep in mind axle placement. What this will do is stop the kart from flexing side to side in a turn.

Now next question, do you have all the other parts? IE axle, seat hubs front spindles etc?

 

[superballskart]

Im waiting to get more steel to do all the lateral supports and I have the spindles and mounts off of a 85 Suzuki 185 which will be welded to a 2x2 11 gauge square tube thats like 4 foot i can cut it to length i need....should imake the front as wide as the rear just to be stable or will it effect turning?and my rear axle is 40 inches have a 30 tooth on it thinking of going to 38 the engines sprocket is a 15 tooth and I really don't need to go 70 haha maybe all less cause all imma do it tear threw my back yard

 

[thepattonman]

Is the sprocket adjustable on the axle? meaning can it slide back and forth on the axle. If not no biggie but I would definitely have a rolling chassis before I installed the engine.

 

[superballskart]

Yea I can move it wherever it needs to be and I was going to get the front on and engine then do the rear axle that way I don't have to make a tensioner and to see how far up I can move my axle forward

 

[thepattonman]

Keep in mind with a tensioner you can change sprockets to different sizes and not have to move anything. I usually use a serpentine belt tensioner for my chains. Believe it or not works extremely well. You can find them at a junk yard for like 10 bucks. And when the chain stretches it will keep it tight. Just a thought

 

[superballskart]

Yea I forgot that I might be changing my sprocket but then I could just use another chain I got 3 that I can resize and they are #520 which is correct for what I need

 

[thepattonman]

I tried that and it ended up a mess trying 1/2 links and trying to find a perfect match. I usually run 520 o ring chains. I found that if you can't adjust the motor its easier with a tensioner.
