Today, we are taking a look at Murray Carbs! We had a lot of issues with the first set of carbs. The question is, is the new set going to be better? Watch and find out! #caferacer #cb750 #motorcycle

I had the same problem on a xs1100. I doubled the springs on top of the slides. Works fine now.

My brother did a big bore kit on his 1979 GS750 and added a Yoshimura pipe and Mikuni 29mm smoothbores. It was a very fast bike.

Oh LORD, a big bore kit alone adds a good amount of power! Plus the yoshi and 29mm makes that thing probably RIP down the road!!!

Og quad cards are all you need! A little jetting, raise he needle and ur done. I'm on cafe build number 3 and I have never not ran the stock carbs. Lean how a carb works and u won't have any problems

I’ve done a handful of builds too. I usually use the OG carbs but wanted to give something new a go! But appreciate it brotha!
you are NOT alone. My murrays carb kit came far too rich, and i'm still trying to dial them in. plugs are more black then Westley Snipes
@zsgarage7710Ай бұрын
That is so frustrating! Definitely not good when your spark plugs are westly snipes dark. Hahahahaha

I would try removing cables from carbs, and run bike by operating the throttle by hand, if the revs are still high, then its not the cables, slides could be getting stuck.
@zsgarage7710Ай бұрын
Definitely could be getting stuck internally. Only thing is I polished the internals. So, idk.

Hello, I had same issue with murrayscarbs on 1982 cb750k, its not throttle cables but jetting. idling jetting too lean. Replace the #35 pilot jet with #47.5 or #50 with 1-1/4 air screw. The needle position were one step too rich, I set the clip at 1st top position. With this recipe my cb750k has a nice throttle, no more brrrbrrr or boowwwoooaah

Thanks for your review, I have a set of Murray carbs I got for free and want to put it into my CB750 but it seems like a headache. I’ll try my best to get it installed because it was free but I also heard to keep the stock carbs just because of the reliability.

Ive got a set of Mikuni vm32's i think on my cb400 and they run great after re jetting them. The 1 into 2 cable is a high quality cable to, haven't had any issues with it. The Murray's set are Mikuni's right? What Mikuni's would you replace them with? Looking at getting some for my cb750 down the track.

You could try reaching out to Barnett cables. They can make custom cables for that carb setup. If you think that cable setup is difficult, try working on Kawasaki triples.

I had the sticky throttle problem too and along with that when I got them the air screws were literally 3/4 of a turn off from each other and were absolutely not synced, I called him and he got angry with me saying that I must’ve somehow messed them up and just about refused to talk to me. Absolutely would not recommend

Got a set from Murray a month ago. Having the same particular issue with a 1980 cb 650. Gonna try to do the new boot route and use carb spray to diagnose a possible vacuum leak. If I'm being honest, Murray isn't the happiest guy when it came to communication on the phone. From all the forums and videos I've seen, some people either have the best or the worst experience from him. It's a crap shoot :/ Might just say screw it and give it to motorcycle wizard to take a crack at it.

@@zsgarage7710 Had mine looked at from this local guy who strictly works on Japanese 4 cylinders for over 40 years. Once I mentioned "Murray Carbs" he immediately frowned. He said that he dealt with a couple of bikes with the Murray Carb treatment with the same particular issue and claims those carbs and all carbs are not "plug and play". They require rejetting, synching and all of the goodness. Sure it fits, but all bikes are different even if they're the same model engine. (Compression numbers, timing, etc.)

Last month, got a Murrays Carbs kit with the solid mount manifolds for my 1975 CB550 with stock 4-4 pipes. The bike is now a hot rod. The transformation was startling and gratifying. I've probably put 500 miles on the set up and am really happy with it. The only issue is that about once per ride, the bike bogs and won't rev above 5K for about 1-3 minutes. It's like hitting a wall--- sluggish to no throttle response other than deceleration. Don't know if it's an issue with the cables or stuck slide. Last night the sluggish response lasted 15 minutes and I was concerned that the bike wouldn't have the power to climb the mountain roads to my house. Stopped to get groceries for about 5 minutes and the bike was back to being a hot rod. There is no good time to lose power on a motorcycle, and abrupt power loss can be downright dangerous. I think I'll lube the cables and see if that helps....

Go buy a injected bike. Carbs are a Labour of love, from my experience, don't put down a carb company due to your lack of knowledge about carbs, they need tinkering with weekly. I'm in Australia never heard of Murray carbs BTW.
@zsgarage771026 күн бұрын
I don’t disagree with you about the labor of love. But I disagree with you on the weekly tinkering. That’s not my experience from the multiple carbed bikes that I’ve owned. But when I get multiple emails about the same issue with these carbs, I don’t think it’s a me problem. But I could be wrong. I did do a lot of “tinkering” off camera and continued to have this problem.
