I have a 1998 VTR1000. I love it. Recently the front pot stopped working, it had become increasingly hard to start and did backfire a few times. Then the front barrel stopped powering the bike. Compression was good, spark was good. I stripped the carbs and on top of the diaphragm I found a bit of burnt foam, which may have been enough to clog the hose and therefore not allowing the slide to work. I can't imagine where this is from as the filter is paper and quite new.
Has anyone else come across this issue?
My next move is to check the hoses and rebuild hoping it leaps back into life.
Cheers. Ben

Re: Vacuum hose blocked
The airbox has two sub fillters. These can degrade & potentialy get sucked in. Lift top & fillter off & check...Item No.'s...10.

Clear out any old stuff & repalce with new or if your a tight butt/on a budget/in a real hurry...cut up a green pan scourer or get some aquarium fillter foam...
It may have been pulled through & is blocking the carb, so give them a good clean.

Making up since 2007, sometimes it's true...Honest...
Re: Vacuum hose blocked
WOW I so didn't see them when I stripped it down. Off to buy some and some carb cleaner
Thanks very much, I have no doubt that will be the issue.

On the left is what's left of the front carb vacuum filter. The rear isn't much better.
Great stuff, with thanks for your help. Ben

Re: Vacuum hose blocked
As the foam is open cell, allowing air to flow through, even bits of foam shouldn't have obstructed the flow through the vac line. I think your problem will be elsewhere, but it costs nothing to try...good luck!
It's not falling off, it's an upgrade opportunity.
