One of your squirrels has asthma? :-k


Actually, it sounds like a bad leak in an intake boot or a vacuum hose is not connected.

[blowerbike]

sounds like your dog was playing with a squeaky toy.
i'm over here by germantown.

Oh lookie there... A 'Burg boy... I probably pass your house every day on the way to work (in springboro).... I'm sure 'tween Blowerbike and I one of us could lend you a hand..

 

[Im Faster]

Im off tomorrow err.. today if any one IS bored.. I do have new intake ooot orings I need to install.. and if either of you have a sync gauge that would be great

 

[Im Faster]

well i have replaced the orings.. i honestly thought they were metal they were so old and hard..

some real smart guy also drilled 2 little holes in the intake boots i guess to sync them or something..

but i just filled them up with some silicone.. gonna wait a while for it to dry before i start it..

lets hope..


i still need help syncing my carbs

 

[Im Faster]

dang it..

it didnt fix it.. it doesnt seem quite as loud... but i only ran the bike for a few seconds...

any ideas where this can be coming from????

 

[Steve]

Are your silicone plugs still there? :-k

Hopefully they did not get sucked into the engine.

.

 

[Im Faster]

no there all good so far lol

 

[Im Faster]

Okay.. so while the bike hadent warmed up yet... i was putting my hand over parts of the motor trying to figure out where the sound came from..


and this area is where it appears to be coming from
could it be the cam?
or the gasket for the cover?

anty ideas?

any advice before i tear into this

That is definitely the bike sucking in air in the video, mine did something like that on a smaller scale when one of my exhaust pipes was not on tight enough after a previous rebuilt.

How soon did this start, did you do any major work recently? Check the bolts on the pipes... maybe one is loose. (but careful they break a lot if you try to take them out, just do visual inspection for now)

Is there anything he can put on the boots or pipes to see if its sucking in air? for some things soapy water is ok not sure if that applies here.

 

[Im Faster]

well dang it.. i took the water bottle to it.. and found a leak from loose spark plugs...

however it did not fix the problem....


it has to be some where that has back pressure.. because it doesnt do it under throttle

Hi,

Bad valve guide?



Thank you for your indulgence,

BassCliff

 

[Im Faster]

how can I check ?

 

[Skateguy50]

so nothing on the header side? I swear mine sounded just like that but not as loud when pipe #1 was connected loose. I tightened up the rear mount before the head and made it not slide all the way in.

 

[Skateguy50]

how can I check ?

Oh boy thats a big one. I was just in my engine to the valve oil seals where you could check the guides... IF thats the issue it involves taking the valve cover off, the exhaust system, the cams, the head, then taking the valves apart and then putting it all back together with a minimum of new base and head gasket. I included cylinder orings, piston rings, valve oil seals, and fresh honing for good measure.

I would stick to the basic before you dig into the engine, and if so start with checking the valve cover gasket. Has it been burning oil? if the guides are going wouldnt it burn more oil?

I don't know if this will work on a bike motor, but a car motor can be tested for worn valve guides using a vacuum gauge.

If at idle the needle fluctuates between 14" and 19" it indicates worn valve guides or a blown head gasket between two cylinders.

Could be worth a try. Hook each carby up individually and see what happens.

tightened the exhaust to no avail
