All balls Carb Rebuild
Permalink  
 


As I am always asking Bri to test kits that I have in the shop, thought I would have a go at fitting the all balls carb kit, as my carb needed a overhaul on my OE that I am going to do a full rebuild/ 350 kit on.

So I started off stripping the carb down

Now I think most people buy the kits, just to use all the gaskets O rings, needles and jets, as it is very cheap compared to buying all the separate Yamaha parts and has the benefit of me adding a few bits extra to the all ball kits and making sure the screws and washers all fit. They don't in the standard all balls kit.

I wanted to fit everything in the kit, so I wanted to remove the float bowl to replace the float needle valve set. So all was going well, changed all the O rings, Jets,and  needle set. All very straight forward, just making sure not to over tighten as they are all quite delicate bits.

Then I got to removing the float bowl and the pin is having none of it, phoned Bri and he told me to have a look at the old threads on the forum for advice. Now there are alot of broken float bowl arms out there and I was sure I am not going to add one of them. After reading the good advice, I decided not to carry on trying to punch my pin out and went to Halfords, to buy one of these.

Will carry on with the job tomorrow and let you all know how I get on.

You think they would make them with a removable circlp so damage would not happen.  If you rem it  out, will it not fall out?

What if any is the difference between an american model and (insert you're country here) model? They look the same to me visually, but price is much lower in the usa. 1/2 price for me if i buy from usa.??
Asking as i feel i may need to buy one. At some stage. *maybe*
Can not supply links, but have two all balls carb rebuild kits saved on ebay, one locally, one from usa. Massive price difference. I guess the reason i ask is, the usa seller says something to the effect only valid to usa models, other countries double check?

No difference apart from the parts I have added to make sure it all fits and also I have to pay import charges when getting them here, which you will not have.

Hope that helps

Steve

Think He is just trying it on, you will be fine with the other kit.

Great news, i got the float pin out today, without breaking anything. This is the first time I have tried to take one out and glad I bought the automatic punch, can't believe how well they worksmilesmile

Now need to crack on as I have a date to go ridingwinkwink

Great feedback, i was a little worried about trying to remove the float (which i ended up not doing). But good to know that a simple punch will save what i would imagine to be MORE money on replacing the carb.

Yeah, local sellers have about $90, whilst usa seller has $46 (after conversion) inc shipping.
Still may buy one, as seems i have a leak. Was hoping it was out of the fuel hose, but just a basic looking over, appears to be from the back/bottom of the carb.

I watched a video that had the pin that was directional(aka only could be pushed out one direction) , but he mentions this is not normal for most.

Edit:spelling

Is the leak coming from the bottom of the diaphragm cover? easy fix, with the 2 O rings and maybe the diaphragm, worth checking first, as them bits do not come in a standard all balls kit.

Hope that helps

Steve

Looks like you will need to face your diaphragm cover before putting it back on Steve wink

 As you blokes know i'm a bit of a noob. With ttr250 things.

I am leaving it sit overnight, with a container under carb area, to see how much of a leak i have.

These o-rings, and diaphragm are these bought via a local yamaha dealer?

I do not have much time tonight to do much, other than turn the petrol on, and see it leak out onto the ground, TENTATIVELY looks like maybe ever the over flow hose??? 

When petrol is switch off does not appear to leak at all. Having said that, petrol was off last night, only for me to find a small patch this afternoon after work. Plus the smell of petrol in garage.

I recently pulled carb out, so perhaps i damaged things, or did not tighten things up properly.

Give the side of the carb a gentle tap with a plastic type mallet, it may just be a stuck float issue.
