I have a yamaha Blaster 200 CC year 2000 and i dont know what has happened to it. When i was riding it this winter there was snow on the ground and i was spinning alot and i think it over heated because it killed on me when i started it i kept trying to get it to the garage and it kept shutting off until once it didnt turn on again. So i drug it up there by hand and let it sit until like 2 months ago and it wouldnt start. We pulled it behind the 4 wheeler a few times around the house and it started and finnael ran normaly again. Then about 3 weeks ago i was riding with my cousin down a trail and it was raining all day and there was some mud. I was riding it down the road going pretty fast when i felt something go wrong so i let off and it killed. I let it sit for a bit to let it cool off but it wouldnt start so we pulled it behind the 4 wheeler and kept riding it that day and half of the next. I dont know what to do now tho ebcause it wont run without being towned behind another 4 wheeler to start and it doesnt have as much power like that. If you know what may be wrong please help

Sounds to me like you have damaged your top end. You need to get the compression tested. A mechanic can tell you from this test if that is whats going on. If it is, there are lots of items that can cause top end failure. I have redone several Blasters over the years and am aware of some issues they had with their oil injection - this can cause the type of problem you might be experiencing..
Get it checked out - it will only get worse to the point of total engine failure..

dang ok thanks man i dont know what we will do because last year we spend 1600 plus on engine for piston cracked cranckcase etc..

I had the same thing with my old banshee happen, after going on a long ride it wouldnt start up at all and the only way to get it going was to pull start it and when you did that it ran like shit. I didn't ride it for like 4 months after that, and in that time I had done everything I could think of to get it running(clean carbs, check top end, etc) and nothing worked. The last thing I did was drain the gas and replace it with some fresh gas and oil and she started right up and rode fine ever since! I don't know if that's what is wrong with yours but it's worth a shot before taking it to a shop and getting charged 50+ dollars an hour.

ok thanks man im thinking(well dad) is thinking that it may be the fuel filter also because we replaced it about 8 months ago . So I think maybe it could have soemthing to do with gas, how did you drain it? syphon?

I just drove it so much trying to get it to run correctly that it finally ran out of gas and i replaced it haha, but you could pull the gas line off the valve and drain it like that.

Smart one dumb ass... How many times have i told you that it will overheat VERY easily in the winter... Your about as sharp as a marble... Hope your dick is bigger then your brain... Cause obviously you don't have much up there...

ok well i drained it earlier by pulling gas line off and put some good gas with seafoam in it and it still runs bad. I dont know should i let it sit another 4 months then try again thats what i did last time

Oh also do you think oil would have to do with it? We use Cabelas Marine 2 cycle oil in it, i herd its thicker or something.

If it still runs bad, clean the carb and check the floats to make sure its not getting too much gas. Its real easy to clean and check it. If that doesn't solve the problem, start the engine and feel if it warms up faster than usual, that can help you determine if its running lean or not getting enough oil. Another thing you can try is disconnect and plug the oil pump hose, drain the gas tank and then add 32:1 gas&oil mix. If it runs fine then it was your pump,if not you need to check the compression and probably do a rebuild. I detonated a piston in ours (it probably broke from letting everyone use it as a practice quad for beginners and it had a ton of hours on it) but I rebuilt it myself for $100 dollars, thats including $20 for gaskets and oil, $55 for piston and clips and $25 for a machine shop to bore and hone the cylinder. One thing I forgot to do was loctite the kickstart lever which fell off while riding on my frozen pond last winter.

last year i have tryed to clean the carbs but ran into a problem that one screw was stripped and idk but alot of screws on this 4 wheller get stripped to easy... oh also if i did figure out i need it rebuild how much experience do you think i would need because i know if i bring it in we will end up spending another grand probably

I would do it myself if I were you. It will cost a heck of a lot less then taking it to a mechanic! Just be glad it ain't a 4 stroke...

yeah maybe glad for less work but 4 stroke USUALLY have less problems also

But when they do your screwed!!


Do you think it could just be a leak in the head gasket?

no, a leak in the head gasket would make it rev very high at idle. It happened to mine before. What sucks is that once it comes loose, you need a new gasket. The gasket is a copper crush gasket that can only be used once. It really is simple to rebuild. Just pick up a repair manual and follow each step. The motor has very few parts you need to touch and the clutch can stay together when you do rebuild it.

Yeah, I figured it wasn't. On my old shee I re used the head gasket more than once and it always ran great. I know I should've replaced it but wanted to see how it would run, and it ran great suprisingly.

yeah well when i can get it startyed i either have to hold full open till starts then keep on gas a bit so it wont shut off or pull it behnd another 4 wheeler

what you are describing sounds like it has very little compression or way too much fuel. Take it to someone with a gauge or you can buy a decent one for about $60. That will help you zero in on the problem instead of guessing.

Also, check for good spark. Pull the plug and let it rest against the engine while connected to the plug. Kick it over and it should spark bright several times.

ok well ill check the spark and stuff soon and hopefully it is just the gas which is what my dad was thinking maybe the filter went bad again because we got this fuel filter we got it because it looked the same exact as the other one maybe it was a bit different.

Here's my 2 cents based on your descriptions. First thing you payed way to much for the original repairs (unless you had the engine restored to like new condition). Next thing is stop wasting your time guessing and have the compression tested. You have described the classic symptoms off a worn or damaged top end. If you spin it fast enough (like tow starting it) it will build enough pressure in the cylinder to start and run, untill the rpm's get low enough and it stalls. If the fuel filter was plugged it would run better at lower rpm's, but at higer rpm's it would start to run poorly since the fuel flow can't keep up with the demand.

Too bad you didn't live near Mid-Michigan. My labor rate is cheaper than most other shops and I give honest estimates. Sometimes I give away some labor just to get a guy back running. I hate to see a dead ride with no hope of being fixed and even more so I hate to see a guy that had a good ride but can't afford to fix it and sits on it too long and eventually looses intrest in the sport. Good luck.

OK steve im with you 100% but first of all i would need to get a compression tester and does like any normal car repair shops carry them? Could i just go to say AutoZone and pick one up? Also how much do they usually run for?

Go to Sears and get a Craftsman comp. tester. Probably your cheapest bet. Most go for around $60.00 and up, but I think Sears might be a little cheaper. You might also find one at Auto Zone or others, but make sure it has the hose that screws into the correct size spark plug hole and not the one with the one size fits all rubber tip, otherwise it becomes a two man job. Once you have the hose and gauge hooked up it is important that you hold the throttle wide open and kick it over untill the gauge stops. If the reading is 120 psi or above your good to go, but if it is anything less your cylinder and/or piston and rings are toast. 100 psi and above may run, but start hard and be low on power. Good luck.

hey man here is the deal with ur blaster i know for a fact. Check ur reeds they are probaly busted or cracked and change your plug. i had the same problem man.

I see you are in MN. If you are close enough, I could check it out for you. I work on these things all the time and my labor rate is cheap compared to a shop. PM me if interested and I'll give you my contact info. Soundslike the one in my garage right now. Bad top end. Total parts and labor with a tune up on this one was under 200.
