I’m guessing that people are still running the power jets on their carbs when they state main jet sizes?...

@DtxPower Best jetting for Athena 170 is 300 main jet on the standard Mikuni tm28 carb but with the powerjet blocked off. Just cut the rubber tube in half from the float chamber to the powerjet then block the 2 halves of the rubber tube with a couple of 5mm threaded bolts or similar.

@kevin I want to go with a 2.0 or so. I don’t know the increment’s. I have a 2.5 fitted ATM...

@garth link text As for cleaning it, I admit I usually leave my carb alone as much as possible and leave it for those more experienced then I however cleaning it isn’t too hard. If you can take the carb off yourself then locate someone with an ultrasonic cleaner and Chuck them a tenner, failing that go to your local bike shop. However there are plenty of extremely detailed and fool proof tutorials on YouTube for the DT125R look this, courtesy of my favourite grumpy old git of a DT enthusiast, Frankie. link text

@dtr-nsr Thanks for the input guys. It's a very interesting topic, which will have many viewpoints and will surely be a hot debatable one for many years to come!!!

@theportingmaster Thanks alot , just what i wanted to hear it narrows down the "to buy" list where u running with or without powerjet circuit ?

@markus-w said in Air filter oil. Ram Air foam filter: Hi all, my foam filter is a bit dry so I have order a can of filter oil but was wondering has anyone used any other type of oil just to get me going until my order arrives? https://www.ebay.co.uk/itm/283683433382 One of my first purchases, comes with piper cross air filter cleaner and conditioner. £20 too. Bargain.

@Calum okay, will do that later when the carb is complete

@SpookDog yes the spring, rubber parts and piston are available at mikuni

mikuni topham should have it if its the mikuni carb

@declan alright Thanks for the help!

@Darty Oh, didn't think of the wr inlet thing. I'm actually trying to modify the original inlet boot right now, if the project is successful I'll post some pictures. But thanks for responding. I don't think I have the skills to design something like that but I could try. I just really don't like my pod filter because it gets wet easily and just sucks a bit overall.

@Arild said in Best carb for the dt125re 2006: @declan yeah my experience with them is the same, thought id post it because some people might not give them a chance because of the price compared to the branded ones that are 3x or 4x the price and think the replicas must be shit since theyre way cheaper and come straight from china, but so far ive heard nothng but good about them so if your looking at a new carb they seem to be a great option Been thinking of getting myself a replica TM30ss/TM32SS. The angled spigot as taught to me by darty is very helpful if you do any sort of off roading with your bike. However I certain can’t justify £150+ until I know the setup works very well

@Darty thanks

Well it's going to be specific to that carb. Jets are not universal, they all use different size measurements. Jet the bike accordingly to suit. It's not that difficult once you know what you're looking for. There is a guide on here.

@Glynn123 oh ok. That makes more sence.do you know what the differnece is? I am now running 146 main jet in a koso 32mm carb, but when i rev it at max it wont go over 8k in rpm.

Yea thats true, do you know what the stock jetting is?

@Calum i thought the same thing. a carb doesnt change that much so it should work when paired with the right intake. got a 36mm keihin to work on my dtre so why wouldnt a lectron work

Oh I did not know that... My method was that I turned out A/F screw about the same as the manual says (28mm Mikuni - 1 and 1/4). Then i went for calm ride using only up to 1/8 turn of the throttle. After 10km I checked spark plug and based on colour of it I further turned the A/F screw inwards. So I did not base on factory setting but on colour of spark plug... I hope my English is understandable enough...
