How to protect new exhausts inside?

(1/4) > >>

sprinta:
I have just bought a new set of Yamiya no number 300's and would like to know if any of you have found a treatment or process to protect/preserve, as best one can, the inside of the pipes before use to hopefully prolong their use by stopping/slowing down internal rust/corrosion?

Even from new, as a result of all the various chemicals used during the chroming process, there will be some that will not have been flushed out due to the internal structures trapping some and as a result there will enviably be some rust/corrosion already present.

I know that some recommend an annual filling and draining of old/new engine oil, but this is a far too messy and time consuming procedure for me to do on an annual basics and whilst happy to do whilst before they have been used for the first time is this the best procedure for what would hopefully be a first time and once only process?

I know that short journeys and blocked drain holes are the killer for these pipes and I never do a ride of less than 30 miles and always ensure that the drain holes are clear, but even so the ends of the pipes rarely get more than warm.

Have any of you found alternative treatment/processes?

My 500 pipes are now 30yrs old,

Before you fit them, pour oil into them, and try to coat all the nooks and crannies are immersed,

But your doing the right thing, very few short journeys,

Make sure you get the pipes hot,

Burn any debris out,

For different reasons Sprinta, I add 2 stroke oil to all my bikes; at 150:1 or so, and primarily to prolong the tank life. I’ll assume it can only help wrt exhaust life too, and am now keen to learn what the experts in the field have to say …… ?

Nurse Julie:
Just run the bike a tad on the rich side, rather than leaner.

I'm a fan of adding low dose of 2T oil every four tank fulls or so.
