Update: Rebuild kit should come tomorrow (Thursday) I had another question. Can I just slap on this carb? Even though its not a 07? Or does the carb differ throughout the models. 2007 Yamaha V Star 650 Classic Carbs Carburetors | eBay

Nvm on that carb. There seems to be a shortage on these carbs haha.

Hello, everyone. I hope everyone is having a good day/night. I just recently bought a V star 650 Classic (01) for $1,500. The person who sold it to me said he was selling it for so cheap because he said he messed up the carburetor trying to do a DIY job. Something to do with either the needle inside the carb. So he says. When I start the bike cold, and turn the choke on, it idles good and everything. But when I open the throttle it dies. On my rebel 250 when I did a cold start on her she would let me open the throttle to get the revs up. But that's not even the main issue. The main issue is on 1st gear, when I wanna take off it feels like its about to die, so I open the throttle more and it does the job. I didn't think it required so much throttle to be open. The other issue arose when I was on the highway. I noticed that I went up through all the gears on the 650 and it didn't want surpass 60 mph. Which was pretty bizarre to me. Because my 250 would go 85mph and reach its max speed. It honestly felt like it wanted to go more but it couldn't. The revs weren't even high. In my introduction I gave an example that went something like this "it felt like it was the weight of a 650 but the power of a 250" maybe even less than the 250 tbh. I only say that because it didn't want to go pass 60mph. I just wanted to know if you guys would recommend switching both carburetors out with new ones? Would that fix the problem im having? Thank you so much for taking the time to read this thread. I hope everyone has a good day/night. Any help would be grateful thanks. View attachment 92161

Sounds like he screwed with the mid range that's the needle in the center of the carb with a snap ring on it for the correct height , the same thing happened to me when I put a hypercharger on it and the local Yamaha shop suggested that I drop the snap ring down 1 to increase the fuel which I did and after setting the ratio screws and putting it all back together it bogged down about half throttle I put them back to factory tweaked the a/f ratio and it's been screaming sinse.

your bike is a 2001 (from your 1st post)

there was a change in that time frame, either the throttle position sensor or the fuel cutoff used by the governer - Im not sure if the carbs are interchangable from 01 to 07

I cant answer off the top of my head, but get a positive response from someone before you buy it

The same issue happened to me when I first rebuilt the carbs. The issue for me was the nozzle that the needle sits in was installed upside down, allowing too much fuel to enter 1 carb and therefore flooding it with the exact same symptoms you mentioned. Part #32 on this diagram.

UPDATE: the rebuild kit came in! Im having a hard time remembering which screw goes in first. Is there any complete strip down video on these two carbs and complete rebuild of it? (including the bracket that holds both carbs and outside screws) Or a worded step by step. I appreciate the kind help everyone has gave me here. Im excited to start this rebuild officially. Im at a complete lost on where to start though. Ill be posting all the pictures of the carbs here with every screw I saved from it. I hope I can get this baby up and running. Thanks, I hope everyone has a wonderful day.

I Just got time to get all the parts I took off and organize them. I unfortunately made this a puzzle now. Where do these go??

Any help would be highly appreciated

Normally if the carb has never been touched since the bike was new, you can take it apart screw by screw, take photos of everything, make notes of where every part goes, and then clean it as you go and put it back together with the new parts from the carb kit

if you are not going to take peoples advice you are going to end up with your motorcycle in a couple of baskets for sale as is on craigslist

if you downloaded the factory manual look at the exploded drawing of the carb in the rebuild section, or goto bikebandit.com and put in the year make and model of your bike, then follow the OEM parts tree down to the carb

it will show an exploded drawing of your carb and list every part that is in it with arrows and numbers, and the thread sizes and length of each fastener. You will have to measure all the screws to figure out which one is which

since you took all the parts off without taking photos or notes or making any drawings, now you will have to figure out what each part is by size in mm and its shape from the exploded drawing

there is no real order for putting the jets back in, each one just needs all its parts and spacers and seals and springs as you replace them one by one

I dont mean to sound un-compassionate, you hurried up and took it all apart and piled the parts together, when a bit of your time, a few photos on your phone and some simple drawings would have made it really simple

from your photos it looks like you cleaned the carb bodies up nicely

you can do this - slow down and take your time, and if you are really stuck on specific parts (if you cant tell one from the other) someone can probably help you

but remember some people only log into the website every few days - this is not the yamaha factory service emergency hotline

I am guilty on getting ahead of myself for sure. I managed to take out the broken screw that was in the carb without having to use a tap. Which is really good. It saved me such a big hassle. I was just too excited and got ahead of myself. The video online is a good walkthrough. Thank you guys for the advice. I will be assembling the carb now officially. I got the screw out and the rebuild kit came in. ?

 

[Shawn855]

Also a bit of advice: don't work on it when you're tired. I did mine at 2am and did some stupid mistakes that I would have caught if I were well rested. Ended up having to take it all apart again in the morning.

If you pick up a cheap vacuum test tool from harbor freight, hook the hose up to the fuel inlet post on your carburetor, pump air into it and it should hold the air, if the carbs don’t hold the air there is a problem with a gasket or O-ring on the needle seat. I had a similar issue with my 1100. It ended up being the O-ring on my float needle seat, so I bought 2 new float needle seat kits ($24), replaced them and it ran better. You will also likely need to change your oil because it’s possible that gas has surpassed the carbs and is now mixed with your engine oil which would also make it run like crap and damage the internal engine components due to a lack of lubrication...... never mind lol I didn’t read all the responses ?

Hello, everyone. Its been about 2 weeks since I was on here. Just wanted to keep you guys updated. I managed to reassemble most of the carb. But I had a question: The bolt that snapped off on me obviously isn't working anymore. Is this its replacement? I just didn't know because it had A small opening on it.

 

[dt.15r]

UPDATE: hello everyone, I got most of my carburetor built. But there’s this one screw rhat I can’t find where it goes. I’ve tried climbing down the diagram tree but I don’t see a screw that resembles this.

 

[dt.15r]

I think I got it, it must be this. Check me if I’m wrong

And we have a winner!!!

HAHAHAH, only took about half a day! Im learning from my mistakes. Im glad there's such good people on this forum. Will keep everyone updated throughout my journey of reassembling the carbs

OOPS wrong the spring on the left goes outside under the E clip at the end of the shaft and the yoke on the lever engages the end of the choke plunger.

Yes that looks like the right screw but check my last last reply before you install the carbs.
