A couple golfcart questions (grizzly 600)

[chris200x]

Ok, first. Why don't clymer have a repiar manual for the 99 yamaha grizzly? :rolleyes: Where the heck am I supposed to get one?

Anyone use that heat tape? Ever wrap a header with it? This thing gets vapor locked (i think) I was gonna line the bottom of the gastank and wrap the header up. Will this work? How long will it hold?

[slothminx]

hmmm i wouldnt try wrapping the header in it. but making an aluminium plate bloted to the frame around the header would transfer the heat away pretty good !! and keep the vapour locks away;)

[chris200x]

How bout aluminum foil? :lol: Do I gotta get a book from the dealer or something...







I miss my trike. :cry:

[SpeedBump]

Vapor lock on a Griz....I have heard something about a design problem with the 1st generation Grizzlies. When the quad hits water, it splashes up under the plastics where it hits something hot...engine, header or both. The water turns to steam and the intake system's fresh air inlet is located RIGHTTHERE! Instead of the air coming in fresh and cool, it is steam. I am not sure this is what is happening to yours, but it is something to check into. As for a Clymer Manual, odd they don't make one. Also a Yamaha Dealer should be able to locate you something....maybe a different brand.

[chris200x]

Thanks SB..I called a yamaha dealer and they can get me one but I'd have to put a deposit down with a creditcard. Well I don't have one! :mad: And it's about 30 miles away but I didn't want to make two trips. One to put the deposit on it, then when it comes in I'd have to drive back down to pick it up! Why can't things be simplier.

I've noticed the air intake for the airbox is right under the back of the gastank? WTF? Anyway to remedy this?

[chris200x]

Can that rather large hole be blocked off? This has to be the dumbest design I've ever seen.

[smokinwrench]

Why do you say its vapor locking? Tells us the syptoms and maybe we can help.

[chris200x]

It runs for a little bit then dies. It won't restart til the motor cools.

The valves have to be readjusted. (new topend) a while back. And it's tickin a bit.

The guy I got it from says that's what he thinks it is so that's what I'm goin by!

[sblt500r]

how longs alittle bit? i had a 83 kdx that ran for a few minutes and then died. when it got hot it shorted the wires out on the stator so it wouldn't spark. got the stator rewound and it was fine.

just a suggestion :D

[MTS]

is the gas cap venting? could be creating a vacume, next time it stalls take the cap off and listin for a sucking sound.

[brapp]

no its just a pos. lol j/k but it always had a problem with vapor locking. get a piece of pvc pipe and snorkel it. and it will help but another thing is when you run it hard it runs better. dunno whyt justy does.

[smokinwrench]

Friend of mine put a aftermarket CDI on his predator not long ago. It got to where it was dieing after a few minutes of hard run time. It would start and run perfect for about 5-10 minutes then die and not restart for a bit. Vaporlocking was my first guess. Turns out the cdi had problems causing hard starting when it got hot.

[chris200x]

There was a new cdi put on this thing. According to the reciepts I got. Also the motor had no compression so a piston kit was put on. I think he said that after he got all this work done by a shop he still had the same problem as before. With it dying after running a bit. I'm leaning towards the vapor lock problem. Any suggestions.

[hotroddal]

why are you so intersted in getting a manual, you dont need one, just use your brain.

[slothminx]

yeh seriously chris just surround everything fuel related in aluminium foil and if it still has that problem you can rule it out ;) but also when it stalls have you tried taking the plug out putting a couple of drops of fuel in there and seeing if she runs. if it doesnt you got yourself some other problem.

[chris200x]

why are you so intersted in getting a manual, you dont need one, just use your brain.

Why you ask? Simple really... Then I won't have to rely on young punks like you for the answers. :lol:

[hotroddal]

im not a punk by any means, and i find it better to learn on your own , and if you cant figure it out, ask someone else or go look in a manual as a last resort, but thats just me.

[chris200x]

Oh, OK. So when I go to adjust the valves... I should just guess then huh? :rolleyes:

[chris200x]

Are you serious? :lol: My father told me he used to do that on his old international truck but i just blew it off thinking he was joking. :lol:

[slothminx]

yep im being serious!!!!!!!! it will do just to test it out and see if that your problem then you can make a more permanant fix if it helps ;) give it a try see how it goes

[sblt500r]

now that everyone is saying check the gas cap i remember it happening to me. the 200sx i had, had this on off switch on the cap. why i don't know, stupid if you ask me. was riding it one day and then blah it just died. turned the knob and it was fine. started right up.

why in the first place did it need a top end?

[chris200x]

It had only 90 psi or lbs (not sure how it's measured) of compression.

[chris200x]

I just went out and looked at the cap. No switch on there. The gas gauge (I think) was been jb welded. But I don't think that has anything to do with it.

[sblt500r]

can you blow through the vent hose?

do you know what was the cause of the 90 lbs of compression? i ask because that could be the problem with it now, and was never fixed and could happen again.

[chris200x]

HOLEY SMOKES!!! I just got off the phone with the guy from the shop. There's no aftermarket manual available for this model... He could get me one directly from yamaha.... are you sitting down? $80!!!!! :crazy: Hotroddal... I take back my comments I made earlier. :D

Shawn. I can blow through the air hose just fine. Also it seems to have plenty of compression now. The guy told me the numder it was running but I forgot. :rolleyes: It was alot higher than 90 though. If it ever stops raining I'm going to start taking it apart. You have to first take the front rack off then the front fender then the gastank cover to get to the tank. Then the carb is under that! Life was soooooooooo much eaisier when I was working on that 200x. I could pull the motor on that in less than 30 minutes! Gonna take me all day just to pull the carb on this. :rolleyes: :TrikesOwn

[smokinwrench]

I just have a hard time believing it's vapor locking.

Vapor locking is the result of the gas in the fuel line vaporizing before it gets to the carb, because everythign is so hot.

How about putting a clear peice of gas line on the carb bowl drain fitting. Leave the fitting open this will let the gas go up the tube to the exact hiegth (sp) of the float setting. THis way when it dies and you will be able to see if the carb has fuel in the bowl. I think if the carb has gas in it the problem would be electrical.

One good thing to do is to pull off all the plastic and check out every bit of the wiring. Also loosen all grounds and retighten them.

[sblt500r]

chris before you go spend that $80, rocky mountain atv has a oem griz manual for $60. :D

i'm sure it has way more than 90 lbs now because of the new top end. was just curious what cause it to loose compresion. allmost all 4 stroke top ends will last more than 6 years! unless it sucks in water or dirt. :eek:

[chris200x]

maybe this is the culprit. It's the first bike I;ve owned that has an opening in the airbox like this. I' sure it would let dirt and water in quite easiliy. :rolleyes: let alone the steam off the header. WTF?

[chris200x]

This is probably the dumbest idea wou''l hear from me but how about if I block that tube off and add 1 or 2 of those uni filtered air vents on the lid back from the front where that tube is. At this point I'm just guessing.

Is threre anything I can wrap the header up with like headetape or something similier? Suggestion?

[sblt500r]

thats just a deep water snorkel intake. thats for when you go riding in water up to and over the airbox. if you can, take it off. i wouldn't block it, it will be sucking even less air. if its posibile also remove the airbox lid, but i know you can't on some yamaha's. the lid holds the airfilter in place on some.

so try removing the snorkel, and the lid or put some holes in the lid, so its sucking some cooler air away from the header.

[brapp]

i owned this quad at one time the entire electrical stystem has been replaced , then the carb builds up so much heat under the tanka nd it vaporizes the fuel in the fuellike and the floatbowl and doesnt run verry well but if you run it wot constantly and move enough fuel trough it it runs fine. belive me thats why my girl friend coudl never rid eit but the transmission was totaly trashed. blew it into a million pieces. so dont jump it it will blow it apart.

[brapp]

i am tellign you it just builkds up alot of heat. i rod eit for hours in the snow and thjen it woudl die and not want to restart until it cooled off alot

[chris200x]

Would can I remedy this mototor getting to hot. Drill mores holes in the plastics? :TrikesOwn

[brapp]

try rynnign it without the plastic shrouds arounjd the motor or front plastics i am certin it runs alot better. try it and belive me .i actualy wanted to build vents to let alot more air flow trough it but it wouldnt have helped from what i use dto do with it. 95% of the riding i did was deep mud.

[sblt500r]

was there ever a recall on the grizzly for that kind of problem?

does it have a fan? its aircooled right?

[03 ORANGE SHEE]

hey, i found my old grizz, that was mine awhile back!then josh, then a guy in jersey, now you!

[Mosh]

my brother in law had one of these 600 grizzes. he had loads of problems with it.take the side plastic covers off.they just run too hot.another thing to check is,the tubes coming off the bottom of the carbs.they get clogged with mudd and wont let the float bowl fill back up.the tubes run down between the frame and swing arm.take them off and blow thru them. make sure they are clear.he also had a problem with the wiring harness,but you said your is new.some coneections melted under the front plastic by the steering stem.also,your valves,if adjusted too tight,as the motor gets hot,the stem of the valve expands.this will in turn push the valves some what off the seats,cuasing a loss of seal at the valve seats until they cool back down.if the motor ticks alot,then it is possible that the timing chain is worn and someone adjusted the valves too tight trying to get rid of the ticking noise.hope this stuff helps.i would check those tubes on the bottom of the carb first.very common problem.

[chris200x]

hey, i found my old grizz, that was mine awhile back!then josh, then a guy in jersey, now you!

WANT IT BACK??? :lol:

So which one of you guys beat this thing into submission? :(

Moshman... Thanks for the advice. At the moment the quad is buried in the garage again as i recently moved and haven't had a chanche to work on it. But I will look into these things that you mentioned. :beer
