So I took my tank down to a radiator shop and they said $65-$116 to clean and seal the inside of the tank and I won't have to repaint the exterior. Crossing my fingers everything goes well!

After 3 years of cleaning the carbs every 3 months I realized I had rust in the tank. I've probably spent a cumulative total of $175 in chemicals and sealers and what not in trying to clean and reline my tank. Just spent $160 getting a used one from ebay and get it opened up and it has a bunch of gas varnish and black tar junk, and what appears to be...RUST! I spent almost $50 bucks in stuff to hopefully clean the varnish and junk out of it. Lol, because of the rust in the tank issue, this bike has left me stranded more than once and I'm ready to cut my loses with this bike and send it to the bike bone yard. But i like this bike which is why I haven't.

Question 1.
Does bad dried out gas sometimes look like rust? Or does this new tank have varnish and rust?

Question 2.
If it's not rust, what's the best way to clean this sludge out without hurting the factory coating on the inside of the tank?
(I put a quart of denatured alcohol and filled it to the brim with cheap gas that has up to 10% ethonal in it and am letting it soak, but before that, I put bb's and rubbing alcohol(cuz it's cheap) and tried to swirl it around gently so the bb's wouldn't hurt the finish on the inside cuz I really don't want to have to try and reseal this tank)

I took it for a test ride and took my spare key and when it started acting up I popped the gas cap off and it didn't change anything. It still acted up. It would act up and pull out of it, then one time it died and I could never get it start back up again. It would turn over and over but wouldn't fire. Full tank of gas, and I put half a can of GB44K in it. It turned over till the battery was dead. Had to have my wife tow me home with the jeep and a tow strap. Holy crap that's scary! So I don't know. I seriously rebuilt the carbs 3 months before it started acting up this last time. But now that riding season is over maybe I'll just sell it. I probably should pull the crabs before I try and sell it though. I don't know. Just so fed up with the bike. But thank you so much max for responding. Still if you or anyone else have suggestions I still need to fix it. Thanks

I agree with Paperkrain.  Additionally, I have had my '05 Venox for almost three years and i've put two new batteries in it. The guy that I bought it from said he put a new battery in it the year before I bought it. I replace the stator (or generator), that didn't fix my problem, then I replaced the voltage regulator and that WAS the problem. I bought a battery charger at walmart to charge the battery, but it still dies if it sits over winter.  I took it to a bike shop and they said my charger won't even touch the battery, so they charged it for me and I haven't had any battery issues this summer and I ride about 250 miles per week.

I want to put a windshield on my Venox, but don't like the looks of the big, bulky windshields.  I want to keep the sleek look of the Venox has. I really liked the looks of the Gozzie 1981 windshield, but either they don't make it anymore or I can't get it here in the US. Ive heard guys using the Mephis Shade, but I haven't seen any pictures of them on the bike.  What windshields do ya'll have on your Venox? If you have one can you post pictures of it for me? Also, if you post a picture i'd like to know how much it was and where I could order one.  Thanks for all the help!

I've never adjusted the valves.  Is there any write ups on how to do this?  Thanks for the help max oradea!

  Front carb started to plug off on my way to class and it started to chug going down the highway, I had a test so i kind of limped it to class.  When I got to class my bottom muffler had changed to the blue/gold color they turn when they get super hot, but just the bottom one.  I put some GB44K in the tank and limped it back the 26 miles to home.  On they way back at higher RPMs the power would snap back.  I cleaned out the carbs the next day and it runs great now!  But it has a ticking sound that comes from the upper end of the rear cylinder now, which it didn't have before.  It's always had the Venox ticking that goes away as the RPMs goes up, but it's different now.  The new ticking isn't too noticeable at idle up as the RPMs goes up it gets louder.  When it got hot enough to change the muffler colors, did I burn an exhaust valve?  Or did I fry my oil and now it's not lubricating like it should?  My wife and I took it out today and it doesn't have any loss of power.  I have never adjusted the valves, do I even need to?  I was planning on changing the oil this week.  Thanks for any advice.
