I'll tighten the chain and see what that does to the equation ?

you can't tighten the cam chain bro !, it has an automatic cam chain tensioner built into the back side of the engine case. you have to remove the back engine cases in order to change the cam chain, which means, the starter has to come off, pull starter removed, stator case removed, flywheel removed, then you can replace the cam chain. you will need to drop the rear swing arm in order to get the rear engine case off. and you will need a flywheel puller tool to pop the flywheel off.

Ahh rightio, saw something about the chain tensioner in the manual obviously it's not adjustable, excuse my lack of mechanical knowledge this is my first proper ATV project

also, YOU MUST PULL THE TOP END OFF AS WELL !. reason : the cam followers will drop down in the lower engine if you pull the cam out to replace the chain. you can how ever, unbolt the cam chain sprocket from the cam, and replace the cam chain that way ?, but I always pull the cam out, cuz I want to inspect the cam lobes. tip: the cam sprocket has punch marks stamped on it, they should have 250, and 350 stamped on it ?, YOU WANT THE 350 MARKS TIMED TO THE INDEX ON THE CASE, NOT THE 250 !..LOL.

Ahhh okay sweet, handy tip right there

Start the bike with the multimeter connected to the bike battery. What do you see for AC and DC voltages at about half throttle?

I' seen a mud dobber's nest in the intake pipe and exhaust do some funny things like this.

Hi all, just a general question, is there a specific wire to do with the CDI or something out that cuts the throttle control?

no, c.d.i either works , or doesn't ?. has nothing to do with how the motor rev's, for the most part anyway. in other words, has no control over the carb.

your welcome. keep in mind, this info was for your model/year, newer atvs have a TPS on the carbs butter fly, which is tied to the ecu/c.d.i., yours does not have this .

Hi Rick
Here are my results
Battery without any connections 13.05v
Ignition on : 12.92v
Idle: 14.44v (bouncing up and down)
Throttle no change?? Still 14.44v

Idle on AC .009
Half throttle .009

Hope this give you a more clear idea of what's going on?

Those voltage numbers indicate that your voltage regulator / rectifier are healthy and you can look elsewhere for problems. I'm thinking timing chain problems or maybe a sick CDI.

Hi all, is there anyway to check to see if when you give the bike throttle the spark is becoming more frequent? Leaning toward a spark issues after replacing the timing chain at my Honda dealer. Any ideas, or should I just go new spark plug? Plz note I have cleaned the plug and no improvement.

Replace the plug.... Sometimes Cleaning doesn't help
