Hey, I had my mechanic tear apart my engine and fix the chronic delaminating valve issue. He said that the problem will probably happen again because he had to replace it with OEM parts. For any owners who have had that problem and fixed the engine, did your engine start failing again?
Since my mechanic did the research into the problem, I articulate so I can make myself clear. My engine started to fail in a manner that required me to hold open my throttle at idle, otherwise it would die. When my mechanic took apart the engine, the valves had worn away at the edges. He replaced the valves and gaskets and the bike runs like brand new again.
I ask about this because my friends have been bugging me into investing in an aftermarket cannister (Yosh slip-on?) but I don't want to if I'm going to have that frustrating engine problem again.
How many miles did the bike have on it when the valves wore-out? Exhaust valves only? All of them? Stock exhaust the whole time? More history on the bike would be very interesting.
Aaah ... OK the valve adjustment that you ignored and held the throttle open at startup, then burnt the valve ... and you expect it to happen again ... that chronic problem ... OK ... I am gonna guess you can achieve that again in 3-6 months ...
Here is another hint as to how often it occours on our bikes ... seeing that its a chronic problem and we all have bikes with OEM parts ... search for "valve delamination" and see how many many many pages of threads show up.
And one more helpful hint for you ... hold on to this mechanic ... you got yourself a good un. Nice research he did too ... post his name and phone number, so you know we all know where to take it.
You really need to listen to your friends and buy yourself that yosh slip on, valve delamination or not, pleasing your friends is much more vital.
In case your too stupid to understand the sarcasm that is flowing like the niagra falls in my post ...
Valve delamination - no such thing.
Valve burning - yes, yours burnt, and that's cos you ignored a tight valve.
Design problem - Yes, but not 1/2 or even 1/10 as bad as a kawi, and not one you cannot jet and adjust your valves out of ... well before it burns.
Your Mechanic - He's on crack, and I wont let him put air in my tars, let alone work on my bike.
There are people here who have run 100K on the original motor without replacing a single critical part. I Made it to 48K on a used and abused 89 and it never failed me unless I failed it a few days prior. It does not have a real big design flaw and does not burn valves unprovoked.
Jet the f*(ker to a +1 setup, run a slip on ... or do K&N and slip on and jet to 150 mains, and I dont think you'd ever need to go to that "mechanic" again. Heck, even if you have to ... find another, any one, one from the phone book ... one that is sitting on a highway off ramp with a sign "will work for whisky" ... will prolly be better.
Cool.

Bill - suzuki put better material in the exhaust valves, hence those tend to not burn as easy, intake burns first ... on nearly all jap crap intakes fry before exhausts.
BTW intakes are 16 bucks, exhausts are 24 ... take that sucka ... proof that crappy intakes, better exhausts are the norm.
Cool.

Hmmmmmmmmmmm. Buddha; any chance the exhaust and intakes are inter-changable parts?
prs
Nope, different diameter and I am thinking length as well ...
Cool.
