It sounds like you have something under the needle in the inlet valve.

It sounds like you have something under the needle in the inlet valve.

I'd still be concerned about the noise, something is a miss somewhere and I tend to lean towards the lifters.

Ya I agree, I am going to dig into the front cylinder tonight.

Removed the front valve cover to check the springs. I can't tell if there is a broken spring. I also watched the springs while turning the bike over, the only things that I noticed is the front rocker arm would move a few times before the rear one would (2-4 times) before the rear rocker arm on the same cylinder. Also the front spring did not seem as stiff as the rear when moving.

I also noticed but not sure if its suppose to be like this, the pushrods seem to be riding on the walls of the pushrod sleeve

 

[glider]

Is there adjustable push rods in the motor?

 

[Knuckles]

Iam not sure if they are adjustable push rods or not. I bought the bike used and have no history of the bike. Is there a way to tell if they are adjustable?

 

[glider]

Lift up the covers to expose the lower portion push rods to see if there is the adjuster nuts there..

 

[Knuckles]

Cool, I will take a look at that tonight, and if they are they just may need to be adjusted?

 

[glider]

When you mentioned "... I noticed is the front rocker arm would move a few times before the rear one would" there's something not normal in there and this is where you start the process of finding it.

 

[Knuckles]

Glider, Thanks for the info! So the rockers should move one after the other?

 

[glider]

In most cases yes:s
