Clutch housing for a Cateye?

So, took apart the reduction portion thinking the clutch was behind there, it's obviously not, looked up a clutch replacement for a goped (similar motor, right?) and to me it looks like the entire motor has to be pulled just to remove the clutch from it?

Any help is appreciated.

Re: Clutch housing for a Cateye?

The clutch is located on the flywheel. May not have to remove the entire motor, just the gear setup bolted to the right side of the motor.

Life's too short to eat bad cake.

Ah, that explains it then. Guess I'll be doing that soon then.

Re: Clutch housing for a Cateye?

Don't need to remove the engine. There are 4 long bolts around the unit, 2 on the bottom go thru the right engine mount plate, once there out loosen or remove the two M5 engine mount bolts, pick up the right side till you can clear the engine mount w/ the trans box.

When you say on the bottom, is that bottom of engine plate, so ground facing up or horizontal to the ground? Have a new clutch coming in on Monday.

Re: Clutch housing for a Cateye?

The 2 long bottom trans mount bolts go through the frame engine mount holes thru the trans and into the flywheel housing, there are 2 long M6 bolts on top the trans into the flywheel housing. On the left side loosen the two M5 engine mounting bolts enough so you can raise the trans on the right side and clear the engine mount to pull the trans off, so you can get to the clutch mounted to the flywheel.

Re: Clutch housing for a Cateye?

So, got the motor out to change it, but not sure if I got the clutch in the proper way, bike doesn't want to move, but if I hold it in the air it has no issue with moving the back tire. On the ground, tries to then back fires.

Sorry if the photos are huge. Does the inside of the clutch housing need to be cleaned/sanded out?

Re: Clutch housing for a Cateye?

The clutch direction arrows are pointing to the exhaust port, which is right. That's not the right coil, that's off a different engine, you only have one mount bolt, and it's probably vibrating, is it hitting the flywheel magnets?? There should be one on the threaded hole on the other side, and you can see the top coil mount has nothing to bolt too. Can you see if the pads were contacting the bell?? And yes I would clean the inside, and sand the bell where the pads hit w/ 100 grit sand paper to rough it up, for better grip. Not sure why the clutch is not engaging right, might want to take it off and make sure its on right. You might have some other kind of engine problem making it backfire.

Re: Clutch housing for a Cateye?

Did not realize the lack of the second bolt for the coil. I didn't notice any contact from the clutch touching the bell at all. It idles fine and doesn't miss a beat, without the transmission on it I can rev it fine and no issues there, but once I add in the transmission it's like it's binding on something. I can spin the bell fine, and the outer gear turns, same with outer gear, spin it with ease and bell moves. I'll try the sanding down thing and hopefully find another bolt for the coil. Hoping it's a cheap fix before I dive into a different motor and stuff for it.

Re: Clutch housing for a Cateye?

You have the wrong coil its 2nd mount is on top and your cases don't have a place for a bolt. The iron on a P/P coil is U shaped so you can put a bolt where you see the M5 threaded hole on the right side of the coil that's on it now. It looks like a chainsaw coil.
Sounds strange, everything turn good apart but not when it's together. Since this started after you changed the clutch, maybe the clutch is not working right, new means nothing when it comes to China parts. I would take that spring off and see, and remove the two bolts and take the arms off, you can post photos. Big Photos are fine with me, easier to see.

So, sanded down the bell, put it back together, still bogs down, swap the spring from the old clutch to the new clutch and it doesn't bog down. Ride around and it gets better, but feels like it's totally lacking any take off on it. Swap in a different plug smoother idle, but still lacking take off or top end. Brother was over he's going around on the Cateye, I'm on the Cag, the Cag has a lot more umph and top end to it than the cateye does. Is that normal? My brother has a cateye also and he said his feels like it has more take off and top end.

Would the coil affect it that much?

Re: Clutch housing for a Cateye?

The other clutch probably has a heavier spring, and your engine can't make enough RPMs especially if you have the starter/generator the heavy magnets robbing power from the maybe 3hp engine and the cateye weights so much more than a Cag. Weight is your number enemy if you want to go fast, get the picture, lol. It's not hard to make 4 or 5 hp with some mods, lighten the flywheel, port the cyld intake and exhaust port, rocket key to advance the timing 10 degrees, bigger carb, tuned exhaust like the fatty for piston port.

Re: Clutch housing for a Cateye?

Well, snapped the coil mount. We pulled that coil and checked to see if a spare one we had kicking around would fit, it didn't so we put the one that was on there back on. Fast forward to today, friend comes over showing him everything. Guess that when I pulled and replaced that coil I didn't Hulk it down like it was, fell down hit the flywheel and snapped the mount.

Guess I'll be going with a motor swap. I've been eyeing the predator swaps for these. I think I'm going to go that route. I do have access to a welder also.

Re: Clutch housing for a Cateye?

The alum on these engines is not the best. These engines vibrate so much one bolt is not enough to hold anything. Also the center post of the coil is your engine timing, I put my P/Port coil on backwards and it was hard to start had to put gas down the carb to get it to start, but it revv up with the 10 degree advance rocket key on the flywheel and the coil backwards it was 20 degrees advanced. With a different coil with different mount wear is your timing at is the question. I have had the coil riding on the flywheel before but never broke a tab off.
A lot of people have put the 6.5 hp Predator engine in a Cateye frame. The clutches that fit on that engine are #35 chain and sprockets. I bought a clutch and 76 or 78 tooth #35 rear scooter gear and #35 chain, was hard to find, and it will not bolt up to any rim I have here, so it will have to be modified. The 6.5 has so much low end torque a rear gear that big, it would be a wheelie machine. Here is what I got.

Re: Clutch housing for a Cateye?

My thoughts are to grab one of the blanks and drill it out to fit. Do you know if when you flip the wheel if the wheel will still coast like it does now? I'm used to BMX stuff where you can't just flip stuff like that.

I was playing around with a gear calculator, seems like I could get it to run 55, but that would mean no acceleration. So I think I'll end up with a 60 tooth or so rear.

Re: Clutch housing for a Cateye?

You can flip the rear wheel but you have to weld the freewheel bearing so it does not turn, and weld a rear brake caliper bracket on the right. With a #35 sprocket on the Go-Kart clutch need a #35 rear gear, if you can get a blank #35 sprocket and drill it to fit your rear rim. I tried to drill holes in a PB rear gear with a hand drill, seems like it is hardened, might need a drill press and a M5 or M6 end mill to make the mount holes.
