Rode some creeks today, but, had to stop a little sooner than I had liked. Upon climbing steep inclines the grizz starts cutting out and will die if the incline is steep enough. It reaks of raw fuel. Once level, everything is fine until hard acceleration, or, another hill. I have just turned 50 miles and it sucks 'cause I'm right at 20 hours and was prepared to change the oil and let her rip. Now I have this issue to deal with. My buddy has an '02 kodiak and said yami's are a little rich and he changed his plug real soon too. I pulled the plug and it is not wet... it looks fine it's black around the seat and the electrode is light tan. If the plug is the problem why is it only acting up on hills? It started this early, but it was very mild. It steadily worsened until I was unable to traverse some hills. Anyone heard of this? Thanx for any advice!

Hey Bluegrizz!

Hate to hear you are having all these problems on a new grizz starting out the gate.You said it wreaked of gas on the hills,was there any hitting the ground from the bowl over flow tube?If so it might be a float sticking in the bowl of the carb,sudden take offs or like you said sharp inclines might be making the float stick to the point it`s flooding the carb.In anycase it sounds as if the float setting is way off anyway to make it act like this.
You are still under warranty and the best thing to do is let them fix the problem even if you have to take off from work and drive a few miles if you did not by it at a local dealer.Later on when is when you would want to use the shadtree mechanic`s way of fixing the problem.There could other problems you might not have seen that the dealer`s mechanics might catch for you.

I agree that it could be a stuck float. Try tapping on the side of the carb with the handle of a screwdriver. You can also try to drain the carb using the drain screw. If you do this, be sure you turn OFF the fuel valve on the gas tank first. :)

Drain the carb, then tap on the carb. Or spray some carb cleaner in through the hole. That may help too.

I took the grizz out today, just in the yard. I have a bank and I slowly crawled up it, to see if the problem was still there. I felt not a single burp in the motor. Would it be possible for this problem to remidy itself? I'm not very good with carbs (auto or atv) and do not mess w/ them much. I made several attempts warm and cold... I even sat on the steepest part of the bank useing the motor to hold myself in position and it was smooth as silk. If it's fine now how long before it happens again? Is there something I can do to prevent/ fix the float or should I just wait to see if the problem arises again? I hate to go to our riding place and have it happen again. I took it buy our local dealership where I purchased it, but, they are d**ks and I would rather burn the joint down than drop my grizz off there (McBride's Yamaha, Saint Joseph, MO) they suck ass! So if possible I would like to keep it in my garage. Thanx for all the help guys!

Well, I rode the grizz on saturday and had no problems whatsoever! I guess I will not worry about the problem unless it comes around again. My buddies Rincon is heating up any time you ride it more than 15 minutes (yikes) so he's coming over to clean his radiator, I guess I'll do the same before it's too late. Any tips on cleaning mud from a radiator? Or, is it best to just remove it? Thanx!

Rincon having hot flash`s uh?

Bluegrizz! When you try to clean the raditor try to do it when the engine is cool,or if not have the wheeler running when trying to wash the mud out from the radiator.These liquid cooled motors are not as bad to distort when a sudden
blast of cold water hits them like the older aircooled engines could do when they were not running and where real hot! I`ve known of some people coming in from a hard ride in the heat of the Summer and killing the motor try to wash them down in a hurry and cracking the engine jug of the head.Don`t use a high pressure wash rig on the raditor,it could bend the cooling vanes of the radiator and restrict the air flow and also cause a problem of trapping debris.Take a regular garden hose and spray nozzle and wash out the radiator from the back toward the front to get the leaves and everything back out the way it got in. Hope it helps out your friends heating problems,if not he might have a water pump problem.
