Hi all,, before stripping the old girl down perhaps I should seek advice first! '79 XR500 seems reluctant to shift into 4th and 5th if the revs are high(ish). With clutch,without clutch--makes no difference. Only sure way is to reach down and give it a decent heave by hand, not entirely satisfactory. So, check external mechanism, shift drum,shift forks,splines/dogs etc. Anything else to look at?? Thanks in advance! Muzz.
