Make sure the carb boot isn't leaking at the seal. One of the most common times for a leak there is right after it is installed. To reach maximum speed on the streets the tires should have maximum air pressure. 22 psi front, 25 psi rear.

Make sure the carb boot isn't leaking at the seal. One of the most common times for a leak there is right after it is installed How can I check this ?? Check for vacuum leaks.... 1) Have a fire extinguisher handy. 2) Get a can of something aerosol and flammable... carb cleaner, brake cleaner, etc. 3) Cold bike, start the engine. 4) Squirt little shots of the aerosol on the joint between the intake boot and cylinder, intake boot and carb, both plastic side covers on the carb, and the diaphragm cap on top. Work your way around each joint a little at a time. In between each squirt, pause for a couple seconds to listen. If there's a vacuum leak, the engine will rev up as the aerosol is extra fuel that gets pulled in through the leak. If/when it does rev up, the idle may or may not come back down. If it doesn't come back down (called a hanging idle and indicative of a vacuum leak), you'll either have to blip the throttle or shut the bike off to get it to come back to normal. Keep in mind that you're squirting a highly flammable substance on surfaces that are rapidly heating up. It has potential to get exciting really fast. See #1 as necessary.

Thanks for that info, peejman. Ha ha, this is funny.....just today I was out by the motorcycles and spotted the can of starting fluid. I remembered reading something quite awhile ago about spraying volatile stuff on a running bike to check for vacuum leaks, but didn't remember all the details. Then, as I thought more about it, it seemed kinda dangerous, so I didn't do it. Perhaps is is time to throw caution to the wind......For sure I will wheel the bike out away from the other ones.....

Another way to check for vacuum leaks is to spray a less flamable substance, such as WD40, on suspected leak locations and listen for a drop in engine speed.

It's really not that bad unless you get distracted with something unrelated for a minute or two and then spray the stuff directly on the exhaust. Not that I'd know anything about that.... It burns out before you can get to the extinguisher anyway.

The problem with using carb or brake cleaners is that those substances can cause damage to rubber and plastic components.

I've had pretty good luck with Berryman B-12 carb cleaner. I try to keep it on the metal parts only.

Berryman B-12 carb cleaner is good stuff. Works well. Always have it on hand in the shop. Haven't had problems with it on non-metal parts, but don't typically spray them..

Another way to check for vacuum leaks: https://www.youtube.com/watch?v=BAPy3C9r2zsThe test starts at around the 4 minute mark.
