1981 GS 450 L project

[bakirkwold]

Tonight I fixed the leaking carb bowl gasket. And while I had the carb bowl off I boiled it in lemon juice and water. The jets too. Worked like a charm and of course I did the other side too. For the gasket I used some Threebond 1194 just a really thin coat on both sides of the gasket. I had to be really careful not to get excess on the inside of the bowl. It seems to work just fine. Its got a stronger idle now as well as more acceleration. I am a happy biker now.

My H pipe is now gone. Anyway. It still does backfire a little on the decel. And also once I turn the bike off and a few seconds go by I here a poof why does that happen? My headers are wrapped? One other thing should I feel more resistance when I push the bike in gear with the clutch pulled in then in N? Thanks!

Popping on decel is common in a lean condition. By the looks of your plugs... that may be the case.

The other thing that could cause an obscure 'poof' or thunk in the tail pipes is an exhaust leak. Normally up at the head, but can be common around the clamp where the muffler attaches to the downpipe.

This, too, could cause an excess in popping on deceleration.

And yes, you should feel more drag with the bike in-gear. There's a thin layer of oil between the plates, and there's only about 2-3mm of thow-out max, so you're pushing through that friction, be it ever so small. When you're in gear, you're not only spinning the back tire, you're spinning the entire final drive and clutch basket as well, hence the drag.

Its not an exhaust leak. And I was told that this is the pistons coming to a spot with no spark and the exhaust valve opens and the header(s) ignite it. But he could be wrong. The plugs look a lot better now too.

The only things I've ever had 'poof' on me after the motor was shut off was a 2-stroke dirt bike that was WAY timing advanced, and a 3.5hp Briggs and Stratton power washer. Which my guess the pump kept the motor rotating after the fuel was cut off causing it to 'diesel'.

However, my Triumph Tiger 955i will pop and sputter on decel because of the slip-on exhaust pipe and the slightly leaner map I installed.

Just ride it! If the plugs chop fine, and the thing has get-up-and-go then blast off !

[bakirkwold]

Yup. I got the plugs re gapped. To the smallest of the range. I will get some pics of those up here is a few days maybe. After I ride it a bit.

[bakirkwold]

I got the exhaust ends all painted up today. They where cracking a bit where the baffle folds. So I sealed them up with some high temp epoxy. Here are the pics.

Nice, that oughta look a little nicer and will fit in with your colour scheme too.

[Chrkut]

Thats the same paint i used on my entire muffler. You might need to respray it on occasion, though.

[bakirkwold]

I used 3 coats. We will see.

[bakirkwold]

New tire!

[7981GS]

That is becoming a very nice looking baby L.
It still needs some kind of seating improvement in my opinion though.

Very nice. Better looking than new IMO! Time for a new project!

[bakirkwold]

Thanks for the comments guys!

[bakirkwold]

There you go. A one of kind chain guard. Do you guys like it? Anything I should change?
