100% possible. I too had one boot shimmy loose while riding, the tach started going nuts.

Yes it could cause a vacuum leak, there's alignment marks on the engine boots.

I got my new intake boots today and i see the marks ill make sure they are lined up properly. One more thing if anyone could help. I removed the thermostat housing today in preperarion to remove the carbs. While i was draining the coolant none came out of the bottom plug or the right hand rear cylinder plug i only got a small amount of coolant out of the left hand front cylinder plug and avout a third of a gallon or maybe a little more out of the radiator. I noticed a lot of rust. Should i be concerned about their only being coolant out of one of the engine plugs? I think i will gravity flush the engine with water that way i dont break anything by using a hose to flush it. Bike seemed last time i rode it to be cooling fine. Any help here would be appreciated. Also thanks to everyone for your advice i am new to bikes and learning a lit form you all

Maybe the system wasn't full?

Flushing with a garden hose won't hurt it. I like to flush and back flush, flushing the water in all directions, like backwards from normal flow.

Just run the garden hose into every available hose fitting or pipe until the water comes out clear.

Ok thank you ill do that. I got the carbs off today and noticed an issue right away the front carb slide doesnt do the "woosh" like it should just falls down with no resistance or indication of vacuum, the rear does have the "woosh". Also the front leaked gas out of every hose including the hose that t's and runs to the right "ear" air filter housing. I will get them apart tomorrow but is their anything specific i should look for that could cause the excessive leaking? And im assuming the "woosh" problem is probably the diaphragm either ripped or not installed correct.

Look for chunks of debris that can block the float needle open. Make sure the jets are open and clean.

Yes, check the diaphragms closely.

So I tore into my carbs today I found the front carb diaphragm has a huge tear and is not repairable also the enrichment valve or air cutoff valve diaphragm was disintegrating and pieces of rubber were all over inside the carb. Also I found gas that had turned to like plastic 😅 I have everything to repair these except a new slide diaphragm any advice on where to get one? Also the float bowls are seized together probably the plastic lookin gas deposits gluing them in (my guess) any advice on how to get these screws out?

Diaphragm parts maybe eBay or partzilla, as for the bowl screws definitely get yourself a JIS screwdriver. Great tool for working on Japanese vehicles. I have a vessel screwdriver that has a built in impact. Pretty nifty.

I am using a jis screw driver their just so stuck on they womt budge and its starting to strip. I have new hardware came in my all balls carb kits was just looking for a trick if anyone knew a way to free up the gasy glue thats holding them in. Guess its time for the dremil and a flat head since i dont have to reuse them

A good soak in Seafoam should break down the varnish if it’s an exposed area. I don’t know if it will penetrate the screws though. Not sure how quickly it would work either. The carb bodies are expensive so may be worth taking the slow approach.

If you can get a pair of vice grips on the screw head that can sometimes give good leverage.

No, just make sure all the chunks are picked out of the carbs.

Ok i have the torn diaphram on the front carb its a big tear so i dunno if it is fixable. I was thinking maybe using a light tape and some spray rubber over it maybe that will work? I ordered new rubber diaphragms just in case i cant fix it anyone know of a link on how to switch out just the rubber?
