All fitted,just as well, UPS never turned up with the new one from csm l, then sent email saying I was not in when delivery attempted at 4.59. Bulls##t! I was working on bike right by front door! Long story short coming Saturday after phone argument, driver tried to deliver to no 5, I live at no 9. Every fk'd up delivery I get is UPS, even their app is garbage. Bike starts and runs fine, a lot easier to fit carb as well with the correct inlet.

I have '88 3BN and it was equipped with VM28SS carb. Even user manual can proof that.

That is the correct set, I had the flatside carb with the 3bn inlet meant for the first edition carb, hard to fit carb

The link pipe on the carb is to do with the power jet, just don't ask me what it does!

@oldman Power Jets are awesome.
Basically when the bike is at a decent load but not accelerating, it soesn't need to use all of the main jet as that is too much fuel, the power jet instead takes over which uses slightly less fuel and has a leaner mixture.
They are not there on all carbs.

Slightly of topic but the same part of the engine, is the gasket on the inlet a rubber one? There’s a rubber one on mine and it has an air leak, I remember on my other engine it was the cereal box type

@calum god damn, the bike should run without the choke when I get that replaced then. Fingers crossed! Cheers

You can get some paper gasket adhesive to just ensure it's properly sealed. It's what I've used on my engines.

@ricky0115 For gaskets and obtaining authentic genuine athena gaskets. Choose none other than PJME.
But personal preference. I use eBay for almost everything else.

Loctite Adhesive Spray.
Bought that like 5 years ago and still use it today.
People will no doubt say it's unnecessary. All I can say is I've only built engines with it and never had any problems. But I'll admit it's potentially over cautious.
