Anyone use the universal Mikuni carb mounting flanges on bikebandit for 1982 gs650l?

[leftlostcommonsense]

I'm thinking to replace the old intake boots on my gs650l and saw the universal flanges bikebandit offers to be much cheaper. My only thoughts are will they be a problem since the original intakes have a slight curve and I'm not sure these do? If someone has tried them and found them to work please let me know. On the other hand let me know if there's a reason why there seems to be no talk about them anywhere online as far as i can find. OEM is an option but see no reason if they can be replaced for much cheaper. Also, off hand anyone know the measurement from bolt center to bolt center and overall depth on the originals? No big deal if not it's just I'm not in a place to take a measurement right now. Thanks.

Are your vacuum sync ports in the head? I don't see any on those boots.

No, they're on the boots themselves. I didn't really think of them when considering the boots. How important are they if everything is set before the replacement? Honestly I'm looking to just get rid of any possible leaks down the road as I don't have any issues right now just realized they are pretty old and hard. I'm not entirely sure but I could possibly put ports in them if needed at a later date. I only payed $100 for a bike that didn't run due to the petcock and an owner that didn't think to see if it was getting fuel so in all honesty I'm not looking to pour another 100 or so into rubber that doesn't absolutely have to be replaced at this point just figured i would if it were cheap enough since I'm going to have to later on and I've already got the carbs pulled. The least I put into it the more I can make if and when i decide to sell it. Cosmetic fixes is really all that's 100% needed everything else is in tip top other than hardened rubber boots. Before pulling the carbs I had no leaks but after putting them back on may be a different story IDK. (Disclaimer) Please correct me in any ignorance shown in my statements as I am 100% new to anything that doesn't have a hood and 4 wheels.

They are very important. You can get close with a bench sync but need to vacuum sync to your engine. In fact, after adjusting any valve clearances they may need to be synched again. It's not a one and done thing but periodic maintenance. If you try to add ports later you will most likely create more of a hassle than it's worth. A tiny air leak will create a lean condition and you'll go mad trying to correct it. Beware of using regular hose clamps too. OEM stuff here is really the best option, including the O-rings under the boots.

Ahh, I really appreciate the reply I had no idea it would need to be synced again after shim replacement and whatnot. That's what's so great about this site so I don't buy stuff that'll cause me more of a problem that fixing it. Guessing ebay is the cheapest option for OEM? I see $90 a set including o-rings every day any websites that can beat it?

Parts Outlaw is one of the cheapest OEM parts source sights. I wouldn't buy aftermarket unless you have to.

I have ran them on my bike for 4 years with no issues but a 78 GS1000 has the sync ports in the head. They are made by Mikuni so that is a little better reputation than your average aftermarket source. One concern I had was they do not use o-rings but no problems thus far and the rubber is still soft.

Yep, click HERE, you will see that they are only $29.85 each. Yeah, that's about $7 more for each one, but for less than $30 difference, you are guaranteed to have the right part.

If you are not looking to spend AT LEAST $1000 to make the bike reliable and safe get rid of it now. Most new members, myself included, figured we would do the minimum possible to get out riding. After you pay the tow truck driver a few times, and maybe crash you will change your tune. This is the MINIMUM: http://www.thegsresources.com/_forum/showthread.php?171846-Top-10-Newbie-Mistakes

I understand what you mean about making sure the bike is safe. There is possibly no way on earth I would invest $1000 in this bike without throwing away tons of parts with absolutely nothing wrong with them. If the bike needed it that's a different story but I really got a perfect bike with absolutely nothing wrong with it except tires and the paint job and plugged petcock. According to the title and previous owner it's only switched hands one time before I got it and the guy that had it beforehand took excellent care of it. The only things I've found to be an issue has been hardened rubber intakes but absolutely everything else such a brake lines have been replaced and are still in tip top condition even all the small springs and stuff that would normally rust are in perfect condition. I bought the bike for $100 thinking it would take a while to get it running but after making sure it had gas it fired up immediately. I have never had such luck with anything I've bought to tell the truth so I kind of feel like I stole the bike to be honest...
