Looking at all those pics again.
You got a stock jug there that has been hogged out. When you do that the holes get bigger don't they ?? That changes timing a bit -- NO ??
You also got a big arse exhaust hole there (don't misinterpret)
, putting you at the edge of a snagging ring.
Now you put on a different pipe after it has run well for years
. This changes things NO ??
We all know that we can change our two stroke performance by changing a pipe.
That pipe might have caused fresh charge flow problems.
So I ask: Could this have caused a bit of ring flutter and snagged a ring in that exhaust port ??
After all you didn't re-jet (I think). It may have needed a bit more air now because of that pipe and that's why it ran better with the lid off.
I'm confused now but will hold on to my old theory until a pressure check verifies seal condition or a poo fuel pump.
Before I changed the pipe, and had the old pipe on, I would still have to adjust the airbox accordingly by taking the lid off and on so nothing change there, so when I had to do it at the dunes that was no surprise.I knew changing the pipe sometimes requires jetting accordingly but after changing pipe it seemed like there was no change and didn’t require a rejet.No I didn’t do plug chops and most likely I never will,I know that’s a big no-no in the two-stroke world but I have no place to do it and I’m not suddenly going to have a place to do it. The ATV parts I go to do not have good straightaways for me to do it, they are made for mudding. I’ve Tried it before at the beach, but conditions have to be perfect. Unless it’s the winter much the beach is always too crowded,I’ve tried doing plug chops there before and wind was blowing hard I was afraid sand would get in
Engine when I pulled plug out.
As far as fuel pump,I’ve tried searching for it on here and on YouTube and not finding conclusive answers, can you explain to me how I should do it on my pilot?
Edit: I did find fuel flow rate for pilot is 4.7 ounces for 10 seconds at idle.
Also another thing just hit me,while researching the pump test I found out that 89 and 89 pilot fuel caps are different,that the 89 breathes thru the keyhole and the 90 doesnt,how do you tell the difference between the two? My pilot is a 90 but has aftermarket tank on it so who knows what cap is on it.The reason I bring this up is because with the rain at LS and my pilot leaks a little gas at fuel cap after I fill up the tank was covered on the top with wet sand and gas cap could have been blocked,so if it was an 89 cap and hole was blocked,I'm not sure if that could be problem or not.
Also I messaged methodical again( on Facebook) with no luck,I don’t know why he’s ignoring me,unless he’s upset I did not agree to go with him the first time I contacted him and wanted to try local first.First time I contacted him he got back to me pretty quick so I don’t understand the ignore factor
