If you can't free up brake cables by soaking them or giving them many shots of WD-40, then you may want to replace them with new cables. If you see brown rust fluid dripping out each ends, then definately purchase new ones. To me, having "new" brakes cables is more important then the gas cable.
Not too sure how to help you with the tires. On our trailer that had leaky rims, I installed tubes. This worked great. With softer tires like on a quad, I would assume the tube would shift, then eventually sheer off their valve stems. To stop shifting tubes, you pump them with lots of air. This would make the tires on a quad too hard. Especially for a mini that doesn't have shocks. You're probably looking at new rims.

I have a trax 70 also the two older boys rod it for 5 years. And 2 weeks ago my 3&half old daughter took her first ride on it buy herself.
Its a good first quad. This on still has good power and has no mods jts never been apart. Have you checked the throtel limit scew on the thub throtel. Make shure its backed out far enough.

When I bought mine the brake cable was sticking, but I lubed it and its ok now. It cant spin the tires but you con slide it in the corners.
The only parts I have bought for it are the chain/sprockets and rear tires. That thing will last forever.

What year is it the one I have is A 1986. And for the oil I use 10/40 motor oil,I know its not the best for it but no problems yet.

The wheels on the trax are a split rim the o-ring between the 2 halves could we leaking cousing the flats. This happened to mine.
A tub is also an opsion.

We have a honda 70 too, it's a 1986 and is still in good stock condition. I haven't had any problems with it. I have even taken it out at Pismo and gone up and down dunes with it. It might not be a speed demon with me on it, but it's powerful enough to haul me around for fun. I would just put tubes inside the front wheels if you can't get it to stop leaking. I also run 10w40 in it and have not had any problems with it
With your kids riding the quad, I would just play it safe and replace the brake cables, never know if they might catch while the kids are trying to come to a complete safe stop. A little preventive maintenance goes along way when it comes to safety. JMHO Lt.Dan

I just picked up a trx70. Does it have a govenor on it? I rode it and it seems to lack power. I had a trail 70 with the same engine and it ran good. I ordered a manual for it but it wont be in for a couple of days. My 9 and 7 year old are going to share it. It has enough power for them now, but in the future id like to bump it up allittle.
Any suggestions would be appreciated.

I havnt got that far. Its been cold up here and I just got it on Friday. I have already replaced the chain. That was why it wouldnt move and the reason I got it for $100. I still have to change the oil and spark plug and finish checking the brakes. The fronts are frozen I believe its the cables. Not sure yet. Thanks for the reply I will check into the screw. Should this be able to spin the tires? 70cc is not small for this size quad.
Thanks again.

I just took apart the cables tonight. What and how did you lube them? I sprayed wd40 in them. Thats all i had for tonight. The shoes look ok and the tire are in great shape. I only put on the chain. What oil does it take and how much? I ordered the service manual but didnt get it yet. Is there a filter or just a screen?
Thanks for the help. It will be alittle bit before the boys can ride. We have company coming for a birthday this weekend. So hopefully next week depending on the brake cables.
Thanks for the posts.

Mine is a 1987. The brake cables are still soaking. I m going to look at them tonight and see if I can free them up. I will post some pics tonight on my page.

I have a problem with the front tires on the kids trx 70. They keep breaking the beads. Does this mean the tires need to be replaced? Or a tube? Any suggetions would help.
They love the predator 90. The first ride was Saturday but it was cut short do to 2 flats on the honda.
Also I need to either free up the brake calbes or get new ones. does anyone have suggetions on freeing them up? They just wont budge.
Thanks,

My son had one for the last 3 years. Had all the same problems and then some. If you have the brake cables off, make a small funnel out of thick paper that will fit on cable end and tape it to the cable and tape the seam. Clamp the cable to something in a vertical position and fill the funnel with oil, then wait till oil is coming out of the cable end. You might have to work the cable some with channel locks back and forth to get it sliding properly. The metal wire in the cable has a thin plastic cover over it, if this cover is haging up inside the cable it may be possible to pull it out of the cable alittle at a time and cutting it off , thus eliminating it. I had to do this with one front cable and it worked fine. While the oil is soaking you should take the front wheels off and take the breaks apart( the mechanical parts) clean them up and lubricate them, cause they will stick also. Same goes for the throttle cable and rear brake cable. Now the tires were a problem also. If the beads a breaking I guess you mean splitting( dry rot)?If rubber is good,put air in the tires and soap them down to find the leaks. I had both bead leaks and rim center leaks. Either way, take the rim apart, make sure its not bent, then wire wheel the surface that the bead contacts( cleans off old rubber build up), find a good gasket material and make a gasket to fit in between the rim halves, and use that sticky brown gasket sealer when putting it back together, and let it set up for awhile. This should work if it don't then get some tire sealer and load it up with that, it will work. I had one tire that needed it even after all that other work. I would lift up fourwheeler and set it on a wooden block so if the tire went flat it wouldn't put a crease in the tire. Good luck finding parts, one place that I found is Bikebandit.com, they have the diagrams and all, but some parts they don't make anymore. If your kids ride in water better check the rear bearings, their open cage bearings and may need some attention also,put sealed bearings in ours. The oil filter is just a screen. The bushing for the steering shaft, up near the handle bars, is plastic,and is probly going to fall apart if it hasen't already. They don,t make it anymore, had to make one for ours. The chain idler roller is some kind off plastic or something, it will disintegrate. If its still there you can make a new roller for it by copying the old one, otherwise it's 80 bucks for the roller and bracket, they don't sell just the roller. Thats just the start. Let me know if you have any other questions.
