Just been looking in the tech section and saw that there was a hidden resistor which sometimes fails and causes the bike not to start This is a common thing which was used on all the Suzuki and Kawasaki looms on all their bikes from the early ninetys Normally the resister was fitted in the bottom of the ignition barrel so that if a screwdriver was used to smash the ignition barrel it actually twisted this resister off Putting twelve volts to the wire wouldn't work nor would putting it to earth I'm guessing CCM when supplied with Suzuki engines had to get round the ecu needing to see this resistor in the wiring before allowing the engine to fire In this case it's fitted in the earth cable but in my experience they sometimes also fitted them into the positive side as well in another attempt to fool the thieves. I've personally wired hundreds of motorbike engines into all sorts of race cars and when I started doing it had a hell of a job working it out as nobody would tell you because it was a security thing It didn't appear on any wiring looms at all for obvious reasons Up until a couple of years ago I owned Z Cars which is a company that built motorbike engined race and road cars, some of you may have seen the sort of stuff we got up to I'm retired now having sold the business on to my right hand man but I'm always happy to try help with wiring issues If you want an idea of what I used to do go onto you tube and type in "tour of z cars" There's a few cars and things on there might interest you if you are a petrol head which I guess we all are |

Yes the hidden resistor has claimed many a non runner, I have always refitted them it the neutral external to the loom by the cdi, easy to get to next time |

Balancing two sets of carbs on two engines in the one vehicle is pretty easy when you know how I built my first twin engined car in 1995, at the time I was building loads of grass track single seater cars using honda C B R 1000 engines. I had seven on order and had a pair of engines sat side by side in the workshop ready to fit into two of them. I walked past them and it struck me I could mount two in the back of the car instead of just one Within fifteen minutes I'd worked out a way of doing it and within three weeks built the first car I used one clutch master cylinder and put a t piece into the pipe taking it to each slave cylinder on each engine, that sorted the clutches out I then put two gear levers in the car one to each engine Finally I had two throttle cables one to each engine set of carburettors To balance the two engines I just checked the slack in the cables by eye and tried to get them as close together as I could then held the throttle open with both engines running at around three thousand rpm You can then adjust the cables to each other till both engines start to harmonise You can hear when they are right very much like the sound you get with an old Lancaster bomber or similar multi engined aircraft flying overhead The engines kind of warble when they are right If the car has rev counters in it you can use them but I've done so many twin engined cars over the years I can do it by ear. One things for certain the sound of two four cylinder bike engines revving together at eleven thousand makes the hairs on your neck stand up Plus it's relatively cheap power I guess over the years I've built around a hundred twin engined cars mainly of the grass track variety but I also did some cater ham seven style cars and an ultima sports car with two five hundred horsepower turbo hyabusa engines in it, one engine driving the front wheels one driving the rear that's the one in the tour of z cars clip on you tube Went out on the bike on Sunday had a whale of a time although the forestry tracks I was on were packed snow and black ice making it a bit of a steady run |
