help! pinging and i dont know why!

wr250f95 · 09-16-2007, 01:56 PM

Last night I adjusted the valves on my 96 xr250r, now since the feeler gauge broke

I had to go by feel. Now the bike is making a pinging noise when you get on the gas and when you let off the gas. I cant hear it when its in idle or at wot. is it possible I got my vavles too lose?

thats what i would say. your cams are hitting the buckets at too aggressive of an angle cause that noise.

wr250f95 · 09-16-2007, 07:18 PM

also if it means anything the bike runs with the decomp pulled in, its not supposed to

tigmaster · 09-16-2007, 07:49 PM

ya, the decompressor isnt even hitting the bucket then so um shes real far out. basically get yourself a sheet of paper and use that as the gauge cuz thats plenty of height, u went way to low.

it wouldnt hurt to just wait till they tighten up again? damn im lazy right now, re building my wr's forks kicked my..................

no no no. picture your cam. ok so u know of it exponentially gets steeper up until the tip. instead of gently hitting on the slope of the cam, u are effectively slamming at the bucket with the "side" of the cam. this is real bad for everything including time chain. this puts lots of stress on the chain an can easily break it.

ok thanks tig. what i thought..........

tigmaster · 09-16-2007, 08:56 PM

no prob, dont want to see u have to do any repairs that arent needed.

wr250f95 · 09-16-2007, 09:09 PM

lol I should actually replace the timing chain anyway, it is 11 years old.

tigmaster · 09-17-2007, 06:22 AM

ya, i wouldnt let one really get over 4 years old with the amount of spring tension on valves now.
