Kazuma 90 first impressions and mods
#1
As I previously stated, John at Raceway went above and beyond to get my sons quad here before Christmas. We got it together and he was able to ride it for a minute on Christmas morning around the yard. Had a few hangups, but I think its a great deal for the price. A few issues that I have had and dealt with.
My son loves this thing. It has plenty of power, turns quick and he had it sliding around the corners in under 10 minutes. I actually rode this around for a bit and was highly impressed. It is surprisingly quiet. Front suspension seems to be up to par with all the other minis in this class. Definitely needed to relieve some air pressure from the tires. They varied from 10 - 16 lbs of pressure. Droppped them down to 6 lbs each and it handles much better. Seems to be fairly straight forward and I think with the proper maintenance will provide years of fun for my son.
Here are a few of the things I have had to address so far.
The front tires did not fit on. I had to redrill the rims, to get them over the studs on the quad, no big deal. Used the lock washers as well as some blue loc-tite.
When turning in very loose dirt or sand, the front tires would "lock up" either to the left or the right. There are two stoppers for the steering stem when it turns either way. They were bent out too far and thus prevented my sons quad from keeping the tires from going past the point of no return. I bought some heater hose tubing from the local automotive store, and although it helped, it still happened. I will bend the stops further in tomorrow.
The starter button quit working. Took it apart and found that one of the wires had come off of one of the posts. After looking at the wire and soldering, I would highly reccomend taking this unit apart and resolder the connections. Put it back together without a hitch.
Ball joint was VERY loose. Could have caused a major accident, so I cannot stress enough how important it is when everyone says to go through these quads and make sure all nuts and bolts have loc-tite and are torqued down.
Have had a couple of the lines come off of the carburetor. Bought some crimp on style clamps for those and they work great now.
Planning on replacing the rear shock immediatley. The fronts seem to work OK, however the back does not seem to dampen anything at all.
The dipstick is made of plastic. The shiny chrome where you grab hold to unscrew it out is a plastic cap. This came off immediately and used some gorilla glue to put it back together. This was also true of the black caps that go on the front bumper.
I will keep posting as I become more familiar with this quad and of course if anything else comes up

after reading your post i'm glad i didn't buy a kazuma, instead we brought a sunl 70 and a 90 as replacements for the kazuma 50 meercats. they rode the heck out of them this last week. the 90 has no steering stops, the 70 use to. both turn really sharp. when i assemble them everything went as planned without any problems whatsoever. both started right up first time, the battery on the 70 discharged overnite and i put it on a 2 amp charger for 15minutes and haven't had aproblem since. the 90 is real fast will be my 150 kazuma in a drag race of 300 feet, the 70 not to far behind. the only encounter we had was the chain guard on the 90 is metal and was just tack welded ,broke at the welds so i had to reweld it. everthing else is tight,nothing fell off. the fit and finish on these quads are amazing, after 1 week of pure riding i only had to adjust the chain on the 90 once, i paid $285 for the 70 and purchased the 90 from raceway for $660, now the grandkids went home they'll sit for a couple on months, i did buy a couple of battery tenders for that . these are great quads and would recommed them to anyone looking to buy a quad in the 50-90cc range. one more thing when i got these i did disassemble both quads and assemble them back with lockwashers and locktite,used di-electric grease on all the connectors.

Hello again.
I have another dilemma that Im trying to solve. The floorboards/baskets are a problem as well as the brake. My son has a size 2 boot. I have rebent these floorboards to give him more room and he still has to take his foot out of the basket, slide it out and then over the brake then back in. Very difficult and not very safe for him. Also the footbrake is very high, its not sitting just at the footpegs like most do, it really sits high. I think I will have to bend it, or cut some out and reweld it for him. Anybody have any problems with this?

We bought a Kazuma Mini Falcon 90 for my son for christmas. We also bought a Kazuma Merkat 50 for our smallest son. The Merkat 50, no problems. However we have had nothing but problems from the Mini Falcon. It quit running in 8 days. Come to find out we had to replace the cylinder head. Now, it rattles. We adjust the valves, and it quits rattling for about 15 min. or so, and it starts rattling again. They shouldn't need to be adjusted that frequently. So once again it is parked. Since Christmas he has gotten to ride it for 8 days. We had to wait on parts, etc. I am disgusted that I have spent so much money on it, and he can't even enjoy it. Not to mention, he has lost little bolts here and there. Please, if anyone can help, please tell us what to do.
Thanks,
Amy

Have you called and talked to John at Raceway? He should be able to help with it. If the problem persists, demand that the entire engine be replaced. Where did you buy it from? I have come up with quite a few fixes that are not motor related and can help you with those, it seems since these are so new, there are alot of bugs needed to be worked out. Let me know if I can help.
