    Chain tensioner

    Hello guys, today I checked my chain tensioner, head machined 0.8 mmil tensioner RR I think it's really long and when it screwed my chain without oil pressure gets really tough, what happens when I have oil pressure? break the chain?. Then tried to mount the stock or adding a washer of 1.5 mm and removing the large cap washer, screw the adjuster when everything seems ok because it does not close all but are about 2.7 mm before close to everything, I also remain about 7.5mm of travel of the tensioner. What do you think? as the best solution? I think it's the tensioner thanks stock.ciao

    if block and/or head are milled to .08 mm or more then you can use Rotax Racing tensioner.
    If less then .08 mm have been milled then can use X tensioner.

    That is what i run on my ski (x tensioner) as when decking my head and block it was less then .08 mm.
    I have not run a Rotax Racing or tried so can not comment on how tight it is when installed.
