Has anyone used or have an opinion on HD,s additve(duralt) .Is this particular additive,"duralt "found in amy other products.? I convinced mysely to buy a bottle to try in my '92Evo.It has a mild pinging in the rear cylinder and thought it might be some carbon build up.I tried it yesterday for a hundred miles and It seemed to have a bit more Umph.@ 5.95 per bottle,I would think a similar product might get the same "claimed "results and cost less.Open to all comments or advic e....bike has 60,000 miles and runs strong and virtually problem free all its life." I have researched this forum and not really found a solid answer on HD additives "or "duralt" found in it.

 

I use it periodically with good results. Definite power increase.

 

report on Duralt...have ridden 300 miles and I have noticed more power and does run quiter...no after run(dieseling) .There was an apparent carbon buildup that was causing some of the problems.Only used 1/2 oz to 2 tank fuls total ..probably wont buy any now that it seems to have done its job.The rest goes in the Jeep.....
