so is this fuel ??? motor problems??? or normal ????


OH YA.... all the oil... that is after-run oil...... that is why it is all wet.... (sorry forgot to state that)

Been running Byron's for 10+ years now and have NEVER seen that sort of yuck ! I'll snap a few shots of my 21 gallon 421 for you to see , as I am about to change out the crank because the pilot shaft is worn from a bad bearing ealier this season (locked up and spun on the shaft ) This is my favorite engine too. That burnt up looking black stuff may be from your filter oil ?? What are you using ?

Chances are you will leave some kind of grit in motor just put the motor back together and run the thing!But next motor change to a different clear fuel if you change now most of the stuff will come loose and mess the sleeve up!

I too have been wondering about this. Is there any substance to this post? I have been running tilted and have noticed a lot of coloring on all of my internals on my v-spec. I want to switch fuels since I dont like the high caster oil content in this fuel and the build up it leaves. I have been wondering if swtiching fuels now after a gallon will let that come loose. I have a PTM 3 port from Brian that I dont want this to happen to as well.

ODonnell burns realllly clean...i tried Tilted 30 green for a gallon and it carboned up the piston Real Good...and imo was lacking some bottom end snap that OD has Always had.....also on a side note....when u get a puff of OD in the face u Know its Nitro.....the Tilted dosent seem to have that same Burn........and the tune from 1 to the other is Totally different....so that tells me its something in the fuel....and for the price difference...illl pay a couple extra $$ for the OD from now on.

Red face Ah... OK I see.

Steve,
Make sure your deck height is at approximately .025". Any lower will be hard to tune and any higher will be harder to burn. Hint - Hint - Wink...
If it is harder to burn you end up leaning the fuel out and here you are.

Is this Gen II fuel?

From the looks of those pics it looks like your case is not cooling. Look at your inlet ports on the outside of the sleeve. The only way to do that is to run extremely hot or not burning all of the fuel completely when you are in your exhaust stroke.

Check your exhaust temps against your head temps. Check right on the first corner of your header. Find the hottest reading to compare to what you are reading on the head. You might find a descrepancy there in your readings. Typically, it takes 285 + to burn like that on the exhaust side. This looks alot like the problems guys had when Magnesium heads came out. Their heads were cooling too good while they were killing the inside of their engines.

Let us know what you find.
Hope this helps,
TEX
