Marine organisims 👍

Do you ride an electric bike, or can you buy vegan friendly petrol and oil ?

Is you are prepared to spend the money, a trick bantam is every bit as good as a standard fantic, but will cost 3 times the price.

I'd check plug colour, timing and carburation.

The WHOOP UCI Mountain Bike World Series is BACK at Nevis Range, Fort William in 2024 with the legendary Scottish venue set to host the opening downhill round on the calendar from 3–5 May 2024!! The general area is going to be very busy.

Both of the company's mentioned are UK based , I'm guessing your not ?

I think the hex but is the kickstart spring locator, nothing good comes from undoing it 😂

Have a look on motoswm for engine manuals, can't remember if there is one for the climber, but the bottom end is the same as swm 's. On the bottom of the engine there is an alan key plug, remove to drain oil. Clean the magnet. (Do NOT undo the hex nut) Refill with 1 litre of ATF . Use some super expensive oil if you prefer.

Does the knock lessen when the engine is hot ? If it remains the same I would be looking elsewhere.

Out the " crate " and unmodified - the fantic is defiantly the better bike.

Hopefully the increasing number of demanding / unthanking members read this. You only have to look at their profiles to see they dip in with questions, rarely acknowledge and virtually never offer assistance to others - rant over.....

Most /all the bearings can be bought from a bearing supplier. The number is generally on the individual bearing. Crank bearings are normally c3 clearance.

Happy New Year to you too. Maybe contact Josh 'JP' Pierson on f'book, as he makes swm ones.

Maybe ? https://www.inmotiontrials.com/product/bultaco-sherpa-wes-alloy-silencer/
