a long day all about backfiring Ventures, carb slides and diaphrams,, an 1 old bike

[cowpuc]

Sooo,, still tweekin on Tweeks gettin her ready for another great season of fun..

Todays tweekin was gonna be a simple a matter of finishing up stickin in the Progressives, dropping in some plugs and tossing a carb sync at the old girl.. As usual,, nothing ever goes as planned when playin with a very tired, ridden to death, 83 Venture..

1st off,,, Tweeks exhaust system has been hit by bolders, logs, salt and hailstones so many times that there is no way it will ever quit backfiring and popping... I did notice what seemed to be a much more abnoxious attitude for doing so, so I thought I would dig into that a little too,,, also thought I might be able to help Muay with a little more advice if I found something weird..

Well,, I did.. Once I got the bike back in after warming it up, I hooked the gauges to it and noticed some really strange readings.. Many many miles ago I had diaphram problems on the road and I stopped at a Yamaha shop and picked up a tube of Yamabond to try and do some back yard, road trip fixen,, worth a try right??.. I had checked that old repair several times over the course of time,, always looked great, and thought maybe my diaphram had finally stretched its last stretch.. Popped the cover,, still looked great... Decided to check the other carbs too.. Well,, I found the culprit,, I had a very sticky slide that didnt want to close all the way.. I found that where the slide slips into the throat of the carb, stuff had built up enough that it was holding the slide open and my vacuum gauges couldnt get a good reading.. Carb cleaner on a rag over my finger, a little scrubbing and than a good internal spray down and all was well.. I have extra diaphrams and thought about putting a new one on the bad one but decided I would continue my Yamabond test for another 20k and check it again,, stuffs amazing..

Finished the tune up.. Guess what,, yea it still pops and growls like it always did (cant expect miracles) but repairing that slide helped, A LOT!!!

Even had enough time left to push new fluid thru the old girls hydraulics.. Getting ready guys,,, little by little:backinmyday:

I started the bike today abd set the pms 1/4 turn leaner and I heard a rasspy sound. Yep. Exhaust leak.

Unfortunately it's on the wrong side of the pop but I'm getting more pops now.

So to find this leak, abd loosen and re tighten the exhaust.

That analog meter has got to be over in the "insane" readings Bongo.. I mean, really,, no person in their right mind would walk into an Auto Zone AUTO PARTS STORE for a can of carb cleaner like I did today,, notice they had a few spin on oil filters for motorcycles sitting on the shelf,, take 30 minutes of a salesmans time sweet talkin him into doing some research into whether or not Auto Zone could get oil filters for a 1st Gen... Of course,, being crazy has its advantages,, that same salesman told me I am the first person that he knew of that bought oil filters for that old bike for 5 bucks each AND am having them shipped to my door for free :rotf::rotf::rotf::rotf:

hey old motorcycles are not the only thing that pops and growls.

 

I for one have knees and shoulders that pop

I growl when I have to do something I don't want to do but have too.

 

I could use progressive springs as my rear end sags. As well as my front end.
