Question

on a 2 stroke y do u need 2 change rings after 15 hours

Answer 1

Exactly! A compression test is the only way to know for sure.

I go usually go a complete 16 race season before any engine work is needed. Keeping in mind that these are 2 hour hare scrambles, plus trail riding in between, so I can usually go 32 hours plus with out any problems.

Answer 2

If it's a dirt bike, it's good preventative maintenance. If the rings were to wear down to the point of loosing compression, then the engine is on it's way towards cylinder damage. Then when you finally get around to rebuilding the top end (piston & rings), damage has begun.The motor may not need to have the rings replaced at 15 hours, but better to be safe then sorry. It costs far less (parts and labor) to change the rings, then to buy a new cylinder. 2 stroke dirt bikes with nikesel lined cylinders cannot be bored to repair any damage. They have to be replaced - $490

Answer 3

Actually it is recommended that you change your piston rings on a 2-stroke engine after 40 hours of use. I personally have never followed that rule, and generally would do a top end rebuild in the winter when the weather was too crappy to ride. I would advise you to change your oil every 3-4 rides, and also clean your air filter after full day ride.

Answer 4

There is no hard and fast rule. I assume you are talking about a racing dirt bike (CR, YZ, KX, RM etc.) Racing engines are high maintenance machines, the rings (sometimes only one) are very thin to reduce friction, and after a few races where they get the S--- thrashed out of them wear takes its toll. Back in the 70's when many street bikes were two-strokes they went many miles with normal use.

Answer 5

That would depend on how hard you ride it. Most of the factory manuals will tell you replace the piston & rings every 6 hours. I generally try to do it twice a year when racing and have had no problems with cylinder wear.

Answer 6

Thats really high, the only reason you would need to do that is if you always wanted every ounce of performance your bike had to offer. I ride pretty lightly, about once a month to twice a month, and we go 2 years and rebuild, even if its not doing to bad. Which is about 24 rides or 100 hours or so. The real reason is to avoid damage before it occurs, and performance.

Answer 7

Yes, if your a professional rider sponsored by a manufacturer.
If your not a pro. Change the rings when the engine starts to lose compression.

Answer 8

don't be silly no not unless you ran it with out two stroke oil & seized but once freed should be ok might smoke abit,

rode two strokes for years only once had to change rings on one bike after had done about 5,000 miles

Answer 9

HECK NO, IF YOU HAVE OIL INJECTION THEY LAST A LONG TIME. I HAD A MOTORCYCLE WITH 120000 MILES ON IT AND SAME RINGS THAT CAME IN IT IT WAS A SUZUKI X-6 250

Answer 10

Of course not. Where did you get that idea ??
