This bypasses the Service Manual method of removing console / tank / throttle assembly & manifold to remove the left side tensioner .
Start with the right side tensioner . Remove as per Snake / Gadget's post in this forum .
Do NOT re-fit it , yet .
Remove the banjo bolt securing the two external oil lines located under the tensioner hole - have a tissue handy for the few drips .
On the left side remove the dogbowl (1 bolt) , air filter, plastic backing plate (2 +1), metal U bracket (2).
Move the oil lines out of the way .
Now you will need a 30mm x 100mm 5mm Allen key to access the inner bolt & then the outer .
Rotate the tensioner assembly 30 degrees clockwise and slip it out – be patient , NO force is necessary .
Add extenders to both units , re-fit (L) , Banjo bolt, then (R) as per other post .
When doing the right side one, it is easier to access the inner 5 mm bolt by putting your hand thru the frame from the left .
Re-assemble left side components .
The paper gaskets have 6mm bolt holes & A 21.5mm central hole . I used Molybedenum Disulfide
to smear both sides of my handmade replacements !
