here you can hear the high end bogging. I thought it was an unadjusted H needle, but adjusting it did nothing:

Defiantly does not sound right. I have a 30.5 I put together with a OBR race ported top end and crank. It is a CY 2 bolt. I only have one tank over break in on it and it seems to run very well. Cannot really tell till I get the first gallon on it. Do to the damn heat and humidity here might be another month before I do much with it.

Have you tried another spark plug? I guessing you have but thought I would ask just in case.
 
Looks lean to me but I am half blind. What is that build up just below the threads on the edge of the flat area? How much run time on this plug? Things do not change if you richen it up?
 
But shouldn't there be a larg air bubble in the primer if it was to lean?
The bulb are all filled up, without any air bubble.

Maybe two tanks on this plug. Will try a new plug tomorrow.
Don't know what that residue is.
 
that residue looks like oil, in which case that might be your problem. try a new spark plug (assuming you haven't) and then set your needles to the recommended per the engine builder and try fresh fuel mixed 25:1 and see if that has any effect. not sure of the weather in your area but that might also be part of the problem. i noticed that i have been getting oil buildup latley trying to run it in the heat and humidity here in oklahoma
 
ONE more thing, when tightening the spark plug, should it come to a point when you can't tighten it any more? Of course you can ruin it with to much force. But mine come to a point where its good and tight, but with very little force I can screw it in much further, but I'm afraid of hurting the threads. Should it bottom out? Maybe that's where the leak are present?
 
No the needle settings on the carburetor are what affect the fuel mixture unless you have a air leak in your fuel lines. Just like Sharkey recommended try riching it up. What I would do is go back to factory settings and start tuning again. If it does not do any good going one way try the other way.

if there was a leak at the spark plug you would see residue around the plug. i have to be careful tightening spark plugs because i can strip them out if im not careful, i was called a human impact wrench when i was in teh military because everytime i tightened teh lugnuts on my hemtt the maintenance guys had to get an impact wrench to get them off LOL. tighten the plug down with your fingers then snug it up with the wrench ;)
 
From working on motorcycles for over 40 years and having my own small engine machine shop in the basement I all ways put a little anti size on the threads of a plug. Does not matter what I put a spark plug in I all ways do this. I all so torque all my engine fasteners including the spark plug to book specifications. I have seen the affects of over tightening a plug and over a period of time will mess up where the plug seats and or the threads.

My concern with the pictures of your plug looks like metal on it at the bottom of the threads.

oly thing i see on his plug looks like oil spatter maybe a little ash, i do not see anything that looks like metal. in fact it looked like my plug did the other day when i took it out to install my lauterbacher clutch. best thing i can suggest is for him to try a new plug.
 
mine has a light tinge of brown to it but still has a little oil on it because i am running it a little rich on purpose due to the hot weather we are having here in oklahoma LOL.

I know all about the weather as I live in middle Georgia. We have not had under 100 plus degree heat index in weeks and very few in months. The heat is not what makes it so bad it is the HIGH humidity! Best to all ways run a little on the rich side.

humidity sucks donkey nuts :lol:
 
Yes it does and at my age it keeps me from running my baja till it cools off. Humidity here right now is only 85% at all most 1 AM. :(

i know that feeling it is about the same here in ok, i wake up take a shower, step out of the shower and want to turn around and get back in it to cool off LOL.

anyway i gots to check my adds to see if anyone is buying anythign, i need baja funds :lol::lol:
