Re: need some help on choosing a kit!
a kit is only as reliable as its installation allows it to be.
that being said, if you came into my shop, I would recommend the four (I use the 4g trans which I convert from bushing to bearing, as well as shortening the clutch springs), they are just higher quality engines which is reflected in the price. its not really fair to even compare the two given one is 150 and the other closer to four hundred. you will also appreciate less vibration on a trip that long. when given the opportunity to ride both, all but one person has preferred the four, though not everyone has been able to afford one.
i have no interest in function without form.
