im about to change the crankshaft in my malossi 221 from a mazz full circle{ as it proved to be to restrictive at high rpm} to sips version of the worb5 lip style for reed valve. the one with a welded pin was out of stock so ive ordered the version without is it recomended to have the pin welded or is this a bit overkill???
thankyou in advance for any advice given!!!!!!!
