severdog Posted January 20, 2004 Share Posted January 20, 2004 Have heard of many similar instances when an owner or technician "over-oils" the K&N filter. Quote Link to comment Share on other sites More sharing options...
EVLXX Posted January 20, 2004 Share Posted January 20, 2004 .....garages have been known to cheat on some things like that. NO..... Really..... actually it's really sad how many... shops and/or mechanics are like that. I now of one motorcycle mechanic that was honest... he finally changeed my shimms on my 86 FJ after 70,000 miles. Before that he said it really wasn't neccesary, the shims and clearance were still within spec. Quote Link to comment Share on other sites More sharing options...
pai Posted January 21, 2004 Author Share Posted January 21, 2004 How many miles, Pai? I'm suspicious of anyone who says that the valves needed adjusting.......as so very, very few people have ever shown evidence of needing them adjusted. It has happened that a shop has charged for that part of a service....but it so seldom needs doing that I might doubt the truth of that......garages have been known to cheat on some things like that. 35000km. so i suppose there is no way i can know whether i hav been cheated?

Northman Posted January 21, 2004 Share Posted January 21, 2004 I'd vote for the over-oiled K&N, too........ Where are you, Pai? Quote Link to comment Share on other sites More sharing options...
pai Posted January 21, 2004 Author Share Posted January 21, 2004 i am fr singapore. so its e k&n overoiled. how does it affect actually? Quote Link to comment Share on other sites More sharing options...
Northman Posted January 21, 2004 Share Posted January 21, 2004 You can either take it out, re-clean it, and lightly oil it, or just let it be, and it may clear itself up (although your engine will end up ingesting the excess oil). Several full-throttle runs will clear the matter up quicker..............at least that's my motto. :twisted: Quote Link to comment Share on other sites More sharing options...
pai Posted January 21, 2004 Author Share Posted January 21, 2004 i hav decided to opt 4 e full-throttle run...hehe...but will e injesting part do any damage? btw, how does n over-oiled filter affect petrol consumption? Quote Link to comment Share on other sites More sharing options...
Northman Posted January 21, 2004 Share Posted January 21, 2004 You're basically choking the engine to a point with the over-oiling. The excess oil restricts air flow, and the engine is sucking in some oil at the same time. The oil won't hurt anything, but it may make a mess of your airbox, and could affect driveability. If you're really concerned, pull the tank off, and check out the filter, yourself, to be sure. Quote Link to comment Share on other sites More sharing options...
