Question about Motorcycles
I did the rings about 200 km ago on my 1996 Funduro as part of the second gear fix I did. All going fine untill today. At lunchtime, I went to check the oil level, (after running the bike for a minute or so) there was a bit of a hissing noise when I removed the filler cap (pressure?) Not thinking too much of it, did the check, found about 300 ml too much oil in the motor, drained some out, checked level again, replaced the cap. A couple of hours later, went to leave work, noticed a slighly wierd noise, but couldn't tell where it was coming from, like an exhaust leak or something. Sitting on about 80kms per hour, and woosh!! an explosion of oil somewhere at the top end. Pulled over, bike was still going but the noise was there again but worse. The rocker cover gasket was sticking out, and the oil had erupted out of there under considerable pressure. At first thought a breather may have been blocked, couldn't see any probs. So now I suspect ring trouble! pulled motor out, cylinder off, and the rings are not cracked? Could it be the rings never seated real well, building crankcase pressure? as I did also notice earlier today, a slight lack of power where there is usually heaps? Any ideas?? Regards RIchard

Hi Douglasglass. I'm not familiar with motorcycles or motorcycle apparel, but I used Google to try and find some solutions for you. If you want to try and find some cheap leathers, I suggest using ebay or Craigslist, as well as checking out your local Salvation Army store.
I also found this forum that was discussing the issue of slippery seats- stoooopid-question-how-fix-slippery-seat.html">http://www.ducatimonster.org/forums/tech/120915-stoooopid-question-how-fix-slippery-seat.html. Here are some of the suggestions listed there. Please forgive the spelling mistakes; I copy/pasted the information without editing:
*use a rosin bag to 'dust' the seat occasionally
*Tribo seat covers are listed on ebay. They are made for the pillion area of the seat but you could easily make yourself one for covering whole seat. They are made of that anti-slip nylon material, the kind that's used on the car dashboards...
*How about some of that stuff you line drawers with? That sticky mesh stuff you put under tank bags.
*Local prilla dealer suggested climbers chalk and it works. Get the one that comes in little bag, tap powder on where you sit and ride. When you get off bike no powder remains.
*ever seen those gel thingys people put on top of their dashboards to keep cellys from slidding all ovet the place, I'll bet ya you could just lay one of those on there and would'nt even have to secure it, I doubt it would even move under your arse.
*Athletic tape or grip tape like you'd use to wrap a baseball bat handle with. Not the ppofy stuff but the cloth one. A couple stripes across?
*Armour-All makes a leather/pleather conditioner that will clean any oils or contaminants from the material. I have used it on other seats where people have used regular armour-all on them and made them too slick. It works fairly well to "un-slick" a seat, but may not give you the amount of grip you are looking for....
*where they sell skate boards they sell grippy adhesive sand paper tape that they put on the top of the board to have a better grip,cut some strips and stick'em on the seat.
*glue some afro-lex (you know...the foamy beige material that use in the couches) and you'll never slip again. The only thing is that when it rains, the seat will absorb water.
I wish you the best of luck in resolving this issue. Stay safe!

SOURCE: Loud tick noise in crankcase.
Thanks for the background info. With all the work that has been done and the good readings I can suggest a few possibilities.

hi,might be able to help,a compression test would be a good start,however,if you already have the engine apart,replace the rings anyway,if the engine has been overheated the rings although they look ok will have lost their tension and therefore their ability to hold sufficent pressure against the cylinder walls,therefore allowing blowby,or compression leakage,the other area i would look is the condition of the valve seals and seats,both intake and exhaust,if the engine has been overheated,the seals may have cracked or become weak,whenever i have my race bike apart with the head off i always relap the valves(just a light cut)and this ensures a good seal through the head etc,hope all this helps...cheers ian
