My kid has an MC65, very nice and powerful bike. But we mainly run enduro/trail riding, so the powerband i a little too peaky.
What's the easiest way to shift the power to lower part of revrange?
I was thinking of putting in an fixed exhaust valve, but the cylinder has a three port exhaust, which makes it pretty complicated to fix. Is there any chemical compounds that would last the temperatures in the exhaust? Like JBweld or smth?
Or should I change the exhaust pipe?
Any other ideas?
So come out all you twostroke tuners
