[QUOTE="ThreeSix, post: 229907, member: 5474"] Just take a wire from the + terminal of the battery and then to the big lug on the starter. Damn thing should do something then. Make sure it ain’t in gear. those older ktms aren’t a walk in the park to kickstart. Regardless of who you are. Mess with the valves unless they’re out of adjustment, and your messing entails putting them back into factory specified tolerances. Make sure you use the correct adjustment marks and are on the correct sequence of rotation (usually TDC On compression stroke and a couple marks to line up-outlined in service manual) If you are not god damn sure that your on the correct marks and adjust the valves somehow, it may be really really hard to start, or not start at all. modern 4 strokes should start within 2/3 kicks usually. For most of them, start with the bike cold as normal. Turn gas on. Give the throttle 2 quick cranks to wide open and close. Turn the choke on. Kick it through slowly, and listen to the motor. It’ll make a sound that’s similar to air escaping usually, that’s the exhaust valves opening and closing. After you hear that sound, keep slowly kicking until you feel that same feeling again. Now it’s on the compression stroke. Once there. Kick it from the top of the stroke, all the way through, with all your weight. It should start. If it’s always a massive pain to start, pull the carb off and take everything apart that you can, order rebuild kit, remove all the jets, slide, needle, so on so forth, and let it sit in a container full of carb cleaner overnight. Jets, carb body possible. Needle. Bowl. Float. So on so forth. there’s a lot of crap in today’s fuel that will gum a carb up. The passages in them jets are extremely small in some cases, make sure everything’s clear enough to see daylight through before assembly, and try to record things like adjustment of screws and cables before removing. modern 4 strokes should start within a few kicks. Not a hundred every time. Some are a lot more temperamental than others, and most have a ritual. That’s what works for me. Good luck [/QUOTE]
