u/Shot-Top-8281

Ive just got the bike and its been stood a long time with ethanol fuel. When i got it, it was impossible to twist the hrottle as the throttle butterflies were gummed shut. The slides were also immobile due to the needle stuck in the emulsiin tube. They were a mess.

Ive taken the carbs off and disassembled them to individual bodies. So far i have cleaned #1 carb and all is well with the butterfly snapping shut when released.

The video is of carb #2. As you can see it takes about 3 seconds for the butterfly to close. Do i just need more carb cleaner? A different solvent? Is there any danger if damaging the seal that the butterfly shaft sits in?

How do i move forwards without damaging the seal to the butterfly shaft?

Thanks

I have bought an unloved cbr400rrn from 1992. In cleaning the carbs, i discovered a perished diaphragm.

The diaphragm seems to be sandwiched firmly between two parts of the slide. Does the slide unscrew? I must be missing something as the needle isnt able to be removed, making me think that there is a part trapping both the diaphragm and holding the needle.

Can anyone help?

So i found this last week. It was stocked with water bottles and what i thought was melted ice cubes in a bag.

The timespan has expired. Has someone just forgotten it and has it now become litter? How long do i wait before i remove it?

Sensational riding on almost deserted hills.

I have been swapping frame bearings in a 5 yr old Trek Remedy aluminium for a friend. The pivot on the seat tube has a bearing each side. These bearings are pressed upto a shoulder.

We used an expanding bearing extractor on these bearings and the NDS one came out without any probs.

However the DS one is very stuck ant the expanding extractor and hammer has knocked the inner race and balls out of the outer. The outer is still firmly stuck and due to it being pressed up to a shoulder, its proving v hard to try and drift out.

Pic1 is the NDS with bearing removed.

Pic 2 and 3 are the outer race firmly stuck

Pic 4 is the inner race and the NDS bearing after removal.

So, how to remove the stuck outer race?

i) heatgun/boiling water to expand the aluminium

ii) penetrating fluid for a couple of days

iii) dremel the outer race and hope to either cut a more suitable slot to get a punch into, or weaken it, so it has less tension holding it

iv) a combination of above with some industrial grade swearing.

Help! Any suggestions gratefully received.

EDIT

Well we managed to get it out. We used a Makita hot airgun that was set at 130c. I then had borrowed some blind bearing extractors that comprised of a collet with a little lip at the bottom. This is then attached to a slide hammer.

So, some heat, some penetrating fluid and the collet and slide hammer managed to drift it out.

Thanks for all the input!

So Oulton Park is in a very wealthy part of Cheshire. The farms are wealthy and not some struggling Welsh hill farm or Scottish croft.

Both yesterday and today, this tractor pulls up alongside the wall near Clay Hill. He then spends his afternoon watching the action from over the fence.

The tractor probably isnt even paying duty on its fuel.

It just felt a bit of an insult to the people who dont get a farming subsidy and have red diesel to travel around.

EDIT It seems that the local residents get a free entry pass, so my outrage is misplaced. In fact by putting his tractor outside the circuit he even helped the parking situation.

My dad owns this and wants to move it on. Its all working. Any questions let me know. Its rather theraputic when its running.
