Cool , will have the jets replaced …. Hopefully I should be able to get 97.5 at a local parts dealer , will check that out todayΒ  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 🍻
