Hi,



The rubber part of the intake manifold on my left-hand cylinder is cracked. Is there an easy way to repair this? Bike is 1983 GL650I.



Thanks,

Joshua

Which part is cracked? Can you provide a picture?



I've gotten by with using electrical tape for a while, I was able to wrap it around the intake manifold...however the crack was conveniently placed for this. I've also used some type of RTV or sealant before, I think it was 3M brand weatherstripping adhesive stuff...yeah that's what it was! That stuff hardens HARD and really bonds to stuff, it's in a black tube. I put some of that on the crack and wiped it with my finger, you could barely notice it. After it hardened overnight I started the bike...didn't leak anymore after that!

Thanks guys,



I'll try the RTV black, and see how it works.


try coating it with Silicon if you get a tube of it and coat it all over it will seal it up nice and be flexible

You can get clear or you might get some black.

Its a common problem and unless the cracks go all the way through

its liveable with

people have used various methods as shown above.

One option is to remove the manifold and use some suitably sized heatshrink tubing.

I've seen that done and it looks quite neat too.

I used self amalgamating tape as a quick fix once.

I also heard of someone using a peice of bicycle inner tube.



If you're not sure if the bikes sucking air through it

when she's warmed up, spray some WD40 or similar at it and see

if the engine speed changes
