i dont know the history of either bikes. except they were both at around 20,000 miles. ill probably get the crack welded because its on the frame that i have a title for. i wonder if there is anything honda could do if we could find enough cracks on other bikes.

We have to take into account the bikes are all 20 years old, the frames are probably realisticly more along the lines of 22 years old. The frames were made with an older heavier steel, which was probably coated originally but probably has worn off at certain points. Remember that todays steel is tempered so that its not as prone to cracking and improvements in welding makes welds stronger than the steel its bonding, as the frames of 87 are certainly strong (lets face it there is more steel in an 87-88 frame than in todays vokswagens) they will crack.

I urge everyone who is having their frames welded, its done by a professional machine shop, and not some yahoo with a 110 volt wire feed welder. I cant remember what exactly the frame composition is, but ifwelded improperly they can cause more damage than good.

The source of the cracking is probably more or less from riding. the bikes do take a beating if it be normal nice soft riding, or someone doing stunts. Shocks take 99% of the effects but some is bound to push through... we all know that the seals on the forks go out with regularity, and cause ill effects.

I seriously doubt that honda or any other manufacturer would do anything about a product that they sold 20 years ago, particularly a high performance product that many of us have had the time of our lives tearing up the roads on. If you are shopping for a used one it is buyer beware... and now you know one more thing to check before money changes hands.
