These are the same comments I added to an older thread, but wanted a new title addressing the Komoto specificially. I just bought for the wife a new 05-06? Red Komoto 150. Seems to be a clone of the clones. While searching for something for the wife, I had these criteria: Auto or Semi-automatic, reverse, and some kind of back-up starting method. About all the 150 clones have this. Next was the dual A-Arms up front and price ($1050 delivered). What sold me on the Komoto was that the rear shock was not mounted straight up and down. It is angled and moved forward quite a bit. My theory was that this would give a smoother ride. Since there has not been much review on the newer models, I'll chime in my 2 cents:

1. Assembly was fairly easy. I had a tough time aligning the bolt holes for the front fender bar guards. One of the bolt holes was stripped and the other bar needed quite a bit of bending to make it fit. I broke a fender mount doing this, but no big deal. The tie rod ends that bolt in the center to the steering tube were cotter pinned, but very loose. As far as anything being loose, nothing has jumped out at me yet.

2. Ergonomics. Me AND the wife noticed that you seem to be leaning foward. I think I'll just put on some bigger tires up front. The forward/reverse lever is mounted in a bad area for hitting the leg/knee. I think I'll just glue some pipe insulation to the edges for a cushion. Foot pegs also seem back a little too far.

3. Starting/Carburation: It has a manual choke lever mounted on the handlebars. It has been about 30 deg each time I have been starting it. Since right out of the crate it has started and run perfectly. Even the wife has no problem starting it!!!!!!!!!!!! Filter is KN style with the silk cover.

4. Suspension: Up front, the dual a-arms are great, not stiff, Adjustable, no complaints. Rear suspension has plenty of travel, but hard as a rock!!! The only way I can get it to move more than an 1" is to stand on the rear grab bar and jump up/down. With that and my 180 lbs I can get about 8 " travel.

So far I haven't ridden it hard. I will this weekend though as a test and then go through it more thoroughly. If all goes well we will go with another couple to WV for a weekend ride the following week. Up there can get pretty hard core.

Here's some input I'm looking for: I'm concerned about the location of the air filter not being up high enough. Something up under the seat would be better. Some of those creek beds are deep and unpredictable. I don't want to drown it. But with the battery compartment and the shock mount up so close, I don't know where it would go? There looks like there was a filter in the front end, but that's the first place to get wet.

The rear shock has plenty of travel, just WAY too HARD!! It does not appear adjustable and doubt any adjustment would help. The shock is 10" eye to eye. Does anyone know of a replacement? Or even a spring change? I'll work on the mounts if I have to, but would prefer knowing someone else has already done the testing.

So there are my issues so far. Seems like many of the earlier issues have been resolved with the newer models. After I ride it a little harder I'll give an update.

 

Isn't there an adjust ring on the rear spring? If it is set too high then that would explain both the hard ride, AND the "leaning foward".

 

Where did you get it for 1050.00 delivered. Im interested.

Call to get the best deal. OOPS I paid $1150

Note the position of the rear shock.

 

Coma,

The first thing I would do is change the air filter that came with the quad. It looks like a K&N but it doesn't work like a K&N. It will let dust and dirt into the carb. Now if you look at my pics I did an air filter upgrade and placed it under the seat. So far it has been OK in this location. We did go out riding and went through some small puddles. The only thing I noticed is that I may have a problem with the chain throwing water and mud up into the filter if we were to ride into bigger puddles. I am going to work on a remedy for this before our next ride.

My daughters 150 also has the rear shock mounted on an angle. Over the Christmas Season I had a chance to buy another 150 for a $1000. I almost bought it, but I just did not want another 150. Also I do not like where the reverse gear is placed nor do I like its design. I did notice the quad had a couple upgrades mine did not have. My daughters quad is an 05, the new one was an 06. I did notice they changed the rear shock. The new quad had a stiffer shock installed on it. On my quad, when I put it into reverse and when it engages, it will drop 1 1/2 to 2 inches in the rear and the chain will get a little loose. After I did the air filter mod, pipe mod, and the rejet of the carb, I can get the front end to pull off the ground. Now when I do this, again the rear of the quad will compress and the chain will loosen. At this point the chain will skip a tooth on the sprocket and make an awful grinding noise at the rear axle. If your in reverse and hit the throttle it will do the same thing {just does not come off the ground [img]i/expressions/face-icon-small-smile.gif[/img]}. So I'm assuming with the stiffer shock less compression at the rear end and a tight chain. Possibly no more chain skipping. I just don't know because I do not have the stiffer shock.

Other things I noticed were the tires, they went up one size both front and rear. The rear swing arm was missing a plate that was welded to mine. They also went with a different type and color of paint on the frame. The front bumper was redesigned, and the headlights are mounted differently. Other than that the quad was the same. I don't know if this will helps you any but these are some of the things I have noticed so far. Please don't get me wrong I do like my daughters quad. There are just some things I would like to see the manufacturer change.

Keep us posted on the things you run into with your quad.

SB.

 

I have the komoto 150 also, unfortunately mine is an 05 with the single arms in the front. I added the k&n also, but mine had a spot infront of the battery, under the seat. I cut out a hole and used muffler pipe to come off the carb into this area under the seat. I was then able to use a slightly smaller k&n then the unifilter i have on my kawa bayou. It is about the size of 3 dip cans put end to end. The arangement works great, but does not let quite enough air in at full throtle (it bogs down slightly, with me on it at wide open). This has not been a problem yet because my doughter is still learning. I too added the pipe insulation to cushion her knee. I have also added some skid plating under the frame, and from the front of the swing arm to the little (cheesy) chain guards. We do alot of trail riding and this makes it easy for her to slide over logs up to 6+ inches. Before that she would get cought on the mounts for the nerf bars and it would just stop the little quad fast. I added a thumb lever to the throtle and turned the front tires around. The newer ones look like they have a wider stance up front thu. All in all it has been a good bike, it will do burn outs with me on it it my grass, pulls me up super steep grades, and has run great for 8 months now.
change the oil and have fun.

SB, I checked out your pictures and your bike looks identicle. My rear shock is Red, explaining the hardness difference. (Confirmed, there is no adjustment capability). Though my chain issue is opposite of yours. I took it out for a lap around my track and.................
Any extra torque makes the chain jump teeth. Like getting on it hard around a turn or a donought and coming off a bump throttle on. I did a quick sharp turn and threw the chain. Looking at this chain arrangement closer, I noticed some BIG problems. First, the chain is neither riding straight NOR perpendicular to the front shaft. I can probably get the chain a little straighter by adjusting the right and left side axle/chain adjuster nuts. But the perpindicular part may be more difficult.

Now for what may be the biggest issue: The chain is a little loose to start, but as the suspension compresses about an inch or so it binds up tight. This really pissed me off.

If I can't ride easy around my track without the chain issues, I have a POS. Forget the WV Mountain trip this weekend!!

Cooling off a bit, I will probably pull the shock and chain off, and at various points check shaft-to-shaft distance. Depending on my findings, I may have to modify the pivot point of the rear swingarm.

So far it has run well, but stalls when coming off a fast run. I'm hoping just stepping up the idle will help. I just didn't feel like even looking at the thing after that last ride. I am pleased with the speed and power.

Dave, looks like your air filter mod is the same as SB's. Some rubber flaps should keep the mud off.

And thanks guys for the input. Stay tuned for more of my results.

 

After reading my own post, I realized it might not have been clear. The air filter one the 150 is actually in the enclosed area right in front of the battery. There really is very little chance for mud.

does anyone know how to fix this problem? i even compressed the the seat and frame, then tightened the chain and even used a monkey wrench to rotate the axle in order for a tight chain. even then when you put it in gear the chain becomes loose. i have the chain coming off regularly even though it is tight when not in gear.
the alignment from the rear axle to tranny gear is not completely straight even after adjusting the tensioners.
please help me to resolve this problem, everyone that i call has no way to fix this.

if it was not for the chain coming off and the long turning radius, the yamoto 150cc atv has been a pretty darn good atv, just don't buy a bmx 150cc atv.

cngrichards,

I worked on a forum members BMS(Same quad as the Yamoto) that had your exact same problem. Let me ask you this, does your 150 have one or two chain adjusting arms at the rear axle? The BMS I worked on only had one. Every time they put it in under a load, the adjustment arm would bend and the chain would come loose. So I suggested he have a piece of metal welded to the adjustment arm (not the nut and bolt ) and the lower axle guard. He took the quad over to his cousin's who owns the local Arctic Cat Dealer and they welded the piece on for him. He said it worked like a charm. The chain no longer came loose and the chain quit coming off the sprockets.

If you could post a pic of your rear axle I could show you where to have the piece welded.


Good Luck.


SB.
