You're coil may be on it's way out and may need to be replaced. Check all you're ignition cables for wear and tear. It may also be that the bike is running to lean. But you should not try and play with the air fuel mixture a this may have catastophic consequences. You will need to get it done by a professional.

Hi and welcome to FixYa,

It would seem you posted twice, pls try here, here or here. In some, the wiring diagram is part of the Service Manual. If the year is different, most harness/wiring would be relatively similar.

Good luck and Thank you for using FixYa. Happy Holidays.

would I be better off shortening the rear shock or would the Emig link or something similar be better? Would you still have full amount of travel in the rear with the link? Looks like it would just change the swingarm location to me. Any clearance issues with the rear fender on full compression? Would it balance OK with the front if travel there is reduced to 10 or so?I have an '02 LC4 that I lowered the front forks by sliding them up into the triple clamp about 3/4. I had to put a washer under the handlebar mount to get the forks up as high as I could. Since I weigh 225 plus gear I set the rear sag about 1/4 inch over what it should be. I also bought racetech springs for the front and Adventurer springs for the rear. With my weight and the lowering method I used the seat height is about 1 1/4 lower than stock at static sag. With me on it it drops about 1 1/2 to 2 lower than stock. I can reach the ground easily. I don't really need to be lower since I am 6'1 but I like to ride tight trails and prefer to be able to put my foot down even when off camber downhill. I never botton since the racetech springs do there part, and I still have full travel length.,,,

Yep normal. All my KTM's do that. I don't even hear it anymore because it's mentally filtered out. ;),

any maintance tips?Piston seizures are due to lack of lubrication and/or a way too lean mixture - incorrect ignition timing unless it is a mechanical failure of the rings bearings or rod. Just like a car engine, there should be a thermostat in the cooling system, so that the engine can warm up quickly and maintain an even engine temperature. If the crank and rod is still okay, then check the mating surfaces of the crankcase to cylinder and cylinder to cylinder head. Be sure that the cooling system is clean and that the water pump is working okay. Bleed all the air out of the cooling system before you start the motor again. 2 strokes get all kinds of mods done to them, so it is hard to determine what the correct jetting should be unless the entire intake, exhaust and port timing are all OEM standard. Go with a richer jet and some non-synthetic oil in somewhat heavier ratios, to help break in the new parts. Adding more oil actually can cause the jetting to lean down, due to added weight of the fluid mixture slowing the flow through the jets. There are several Honda Elsinore MX websites out there to help guide you through the setup process, once the type and make of parts are known. Each manufacturer of exhaust and intake systems will have different setup suggestions. Always warm the engines up slowly, until the cooling system is circulating properly. Inspect the carburetor for any kinds of debris or contamination that could cause lean running and verify ignition timing specs. Intake manifolding and/or reed valves need to be checked carefully for air leaks/damage. If the bike was run HOT with failing cooling system, the damage to the crankshaft rod may not be visually apparent, so a crank rebuild may be in order, so you know that the bearings are not damaged. Considering that there was coolant in the crankcase, a crank rebuild really is a necessity, as old coolant will etch and damage ball and needle bearings, as well as the crankpin and rod end. If gasket failure isn't apparent, then you may have to have the cylinder and head pressure checked to identify any hairline cracks that may open up under heat and pressure. Use OEM Honda gaskets to prevent material failures, which can occur with after-market parts.,,,

Check your oil of full you might have a rocker loose you might won't to take it to a shop or just grab a book on your bike and have at it. It's not that hard of a job just time consuming ....good luck.

Try adding an inch (26mm) of fork oil to each fork. Be sure the fork oil level is the same in each fork. Normally there is 3 to 5 inches of air at the top of each fork.

It has a standard LED headlight, so I am guessing you turned it off.

The brake light may only work with the engine running.

Here is the manual. Page 28. Fuses on page 170, look at fuse 6 which is lighting.
