Like alley said the pipe and muffler is not moving with the engine. The muffler is mounted to the frame solid. after it broke the last time I made brackets and mounted the pipe to the engine. I am thinking that the engine mounting bushings are allowing the engine to move to much. If I hold the brake and rev it the engine is twisting in the frame. So a flex pipe at the muffler and new bushings should cure this. I will put E.F.I. on the 300. I got the kit from ECOTRONS. www.ecotrons.com/index.php?ncr=1. Here is another. www.mbe-motorsports.comRoy |

Have you adjusted the valves? With 1746 miles it's time, they are probably tight. set intake to .004 and exhaust to .005.

John, the original muffler and pipe was replaced long time ago. After it broke the first time. I put a supertrapp muffler on it. I also had a header pipe made. I think this time around I'm going to get a 2"x4" flex pipe and put between the muffler and header pipe. I might try a smaller muffler, like this. www.jackssmallengines.com/strapmain.cfmRoy |

The header pipe on my 50cc trike broke again today. This is the third time. It broke about one inch from the flange. The first one broke at the flange weld. The second one broke at about two inches from the flange. This one was made of thick walled pipe. I also made brackets to mount it more solid to the engine and frame. I'm going to redo the mounts and the header flange and pipe. I might look into trying some sort of flex connection. For some reason the pipe is getting stressed at this point.

When I ran the power wire to the fuze block I also ran a 10 gauge ground wire to a wire terminal so I could ground the lights and other stuff there. Behind the fairing is cramped for space so instead of hunting for a good ground I made one.

I will look into the rib.The scooter harness only powers the relays. 16 gauge wire is what I had lying around. The scooter harness is 18 gauge or whatever the mm measurement is the Chinese use. The resistance and voltage drop between 16 and 14 gauge on a short run is minimal. And the wire will handle 20 amp, so it should be ok.

When I drained mine it had about 10 oz in it. The gear box also has about 10 oz. I refilled with 80w-90 synthetic gear oil. 10-12 oz will be good.

I ran a 10 gauge wire with a 30 amp fuse in it up to a fuse block I mounted in the left side glove box. I then power each light on separate 10 amp circuits with 16 gauge wire from the fuse block through the relays to the lights.

I haven't had time to work on a timing circuit yet. What I did is I wired the power wires to the light on one side to a relay. the other side I wired it through a rocker switch then to a relay. After the engine is running I turn the lights on and only one side comes on, then I wait a little while then flip the rocker switch to on and the other side comes on. I used the relays so that 8+ amps of current don't flow through the stock headlight switch. Now I can almost see into the next county. LOL

Wow, what a bummer. Wet electrical connections will corrode over time. Check the connections and dry them. You can use the grease to waterproof them. I use clear silicon caulk. after you put the connections back together put a bead around them and where the wires go in. A tube in a caulk gun goes a long way. You might want to check your air filter also. If it's paper you will want to change it. Paper filters don't work as well if they get soaked. they tend to harden up after dry. If it is foam just take it out Wash with soapy water, rinse squeeze out excess water and let dry. Good luck.

I got lots of shtuff and some times I need to haul some of it, I'll use the truck. Some times I'll take the grand kids out, gotta use the Explorer they won't all fit in the truck or because of bad weather. If I just want to enjoy a nice afternoon or run some errands I ride one of my scooters.

Scooter engines have individual personalities. So what works for one won't necessarily work on another. It is a trial and error system. Find out what size jet is in it now and go up 2 sizes. That is a good starting point. 110- 125 is a pretty good spread, It may take a few tries to get it right.

I'm not sure, but I would think the magnum and compellor have the same differential. I haven't had to tear into mine yet.
