New Airbox Ducts

I'm considering new airbox inlet ducts for the Mikuni BS34 carbs on my 82 GPz750. Mine are hard and have a plastic feel. Are the new ones soft and pliable?
Thanks
Nick

the new ones are very soft, really easy to work with.

Just installed them on my KZ750e with BS34s.
$45 + shipping @ Z1 Ent.

Thanks for the info. Just curious if you replaced an existing set and if they made any noticable difference in the way your bike is running.

Bought the bike with factory Keihins.
Switched to BS34s,changed exhaust and installed the new ducts at the same time.
Ran ok when I first got the bike,now it runs great.
Ducts where rock hard.

has anybody ever tried installing the boots for a set of 34s into a stock intake that had 26s-28s origionally?

That sounds kind of like a Blivet.bj

I bit the bullet and ordered a set from Z1. Hopefully it helps or completely fixes my high idle problem. I won't know for awhile as I'm waiting for parts to fix my starter clutch.

Nice soft pliable air box hoses will help make removal and replacement of carbs almost enjoyable, especially when compared to contending with the typical rock hard examples.

For "high idle problem," would more suspect post-carb air leak as opposed to pre-carb air leak.

May also need new carb holders. And perhaps also new vacuum plugs.

Would test for air leaks by spraying brake cleaner, WD40, propane, etc., about carb holder and any other possible air leak sites, while engine is idling.

Air leak would be indicated by change in idle rpm and probably also smoke from exhausts.

Good Fortune!

I received the new airbox ducts today. Wow! What a difference. They slip right on and cover up to the tabs.

I'm still waiting for parts to come in so I can fix my starter clutch, but I have to believe these will make a big difference, if for nothing else, the ease of putting them on. Thanks to all those for suggesting I replace them.

I installed the new airbox ducts today along with a fresh air filter. I'm pretty sure they fixed my high idle problem and make the carb install so easy now.
Thanks.
