airbox

[angus]

Recently replaced the carb to head inlet manifolds and refited the carbs,having serious issues with re fitting the airbox.have sofened the rubbers with hairdryer and still cant get them on.Any tips or tricks to help would be great.Conan

Attach the airbox first then slide the carbs into the head. It may come down to needing new boots on the airbox side too. Do a search on airbox and my name and you'll be able to read my fight last summer. In fact I'll go look and try to find it for you

It`s as simple as that.I took carbs off,heated the rubbers on airbox and miracles happened the airbox went on so easy,had been trying for a few days wwith carbs on bike.Now I have a kink in the new fuel line I fitted better get it sorted.Conan

Sorted the fuel line,now the bike idles and revs up ok but when I try drive it there is no power bearly moves,have noticed a sucking like sound in the fule line from tank.Could it be something as simple as re-balancing the carbs.With the kink in the line she would idle with choke on and not rev but die when choke off and wouldn`t start without choke on (thats sorted now).Also when I had the carbs off I noticed all the main jets had come out and I just screwed them back in fully is that ok.Conan

Hi,

Have you properly cleaned the carbs?

Feel free to put your bike's year and model in your signature file.


Thank you for your indulgence,

The carbs were checked and were clean.The chrome covers for airbox are still off as Im waiting on new air filter.Could this affect it,bike was running much better before i replaced the inlet manifold boots.Conan

The carbs were checked and were clean.

So bike was sorta running before and you removed carb rack to replace carb boots, found all main jets loose, but didn't investigate carbs any further??? Did you replace the boot o-rings at cylinder head interface?

Yes replaced the boot rings at cylynder head local mechanic looked over carbs after I put the main jets back in said everything was fine,he is ment to be comming back sometime this week to see whats wrong.He thinks since the bike was running sorta ok ish that they just need to be balanced.It was him that noticed the boots gone when he came to balance he first time.Conan

With the airbox wide open and no filter, it'll always run like crap. It's getting too much air. Until you put a filter in there, properly oiled, and seal up the airbox, you'll never really be able to run it.

I see you've started putting your bike year/model in the title of your posts. Do yourself a favor. In the upper left corner of this page click "User CP" (that's User Control Panel) then, in the left margin, click "Edit Signature". Any information that you put in there will be displayed at the bottom of every one of your posts, with no other effort on your part. Pretty tricky.

See the "sig file" below my post? Believe me, I don't type that up every time.

Thank you for your indulgencde,

New filter in still not running right.Rev it up slowly goes to 4 thousand rpm and try go above it dies completley.Took it out tried to drive her and it and you could walk quicker and she will cut out.This has only started since I replaced the carb to engine manifolfd boots.Conan

I'm still worried about those loose main jets that you had to screw back in. Maybe someone has fiddled with needle height and so when you screwed the jets all the way in, now there is not enough fuel flowing thru mains system as needle height is too low.

I guess I`ll get the mechanic I know to look at it as the bike was running ok before I replaced the boots.It was the mechanic who said just to screw the jets back in.The plugs are black and sooty no wetness on them.Conan

I have mechanic coming down to me he says the 2 screws on the right side of carbs above where the carbs fit to the manifold boots are adjustable.I have the haynes manual and says the pilot air screw is pre set and the pilot mixture screw is N/A .Does anybody have these settings from stripping carbs down before. I presume the screws Im talking about are the pilot screws.Would like to have them to hand for when he arrives he said they should be in the manual but there not.Conan
