Cool , will have the jets replaced …. Hopefully I should be able to get 97.5 at a local parts dealer , will check that out today and I am planning on installing new iridium spark plugs , and I haven’t checked the valve clearances the bike had done just 15,000 kms totally so I guess the clearance should be fine .
And one more thing Marcel have you tuned the petrol mixture screw on a 250 ? The manual says not to tamper with these screws 😁, however I had to remove them cause my carbs were too stuck up after sitting for a couple of years ,
The mixture screw for the rear carb was 4 1/2 turns out and the front was almost 2 .. is this the default tuning ?
Any knowledge on this would be helpful .
Cheers 🍻
Thanks alot Marcel, I was confused wondering if the slimmer one goes for the front carb to compensate for the bigger jet at the rear carb .. couldn’t find this info in any service manual as well … ,
It’s running on the stalk main jets 92.5 front and 95 rear a, K&N air filter in the stalk air box … The bike does a top speed of 150 kmph on the highway.. but it’s just that I feel it’s getting too hot … Should I lift both the slide needles to the third groove from top ..it’s in the middle groove now which I guess is the default settings
All the best , but before you take anything apart check some basic stuff … Like disconnect the fuel hose to the carb and check if there is fuel coming out when you crank the engine , also check the vacuum hose to the fuel cork …. Cheers 🍻 … And all the best for your new bike
Yup check the main jet and the pilot jet again I will attach a picture of them from My comet 250 carb , and also try pushing the slides up with a finger and see if they slide back down freely without any restriction…
If everything is fine try starting the bike without the air box on.. may be the air filter is chocked .. so u could see if the slides are moving when u accelerate …
The Gap is totally fine , this is a small pump that squirts a little gas inside the cylinder on acceleration , u can manually check this if it works smoothly , unless the rubber boot is become hard and holding it down,
However this would not be a cause for the acceleration issue that your facing , check pilot jet circuit again and also if both the slides are moving freely without restriction.
