Indeed sounds like the the front Cam Chain Tensioner being worn ( my front one started making noises only at ~80.000 km [on both owned Vfr's 6 gens : 2002/2009, the rear went after more than 100.000 km] - The low milage of the bike doesn't support a Cct problem thesis. - On my 6'gen noise appears when idling not when throttling . Good luck p.s - The part is ~70 usd on ebay. - Getting to the 2 bolts to free the front CCT one requires a bit of work to be done.... (on 6' Gen) - There are some samples recordings on youtube... which can be compared to this exact noise sound.

the way I did it, 2 stage : 1. wiggle the sprocket off by hand (use 2 hands on both sides of the sprocket- not much force is needed, wiggle & pull) ( U can use some wd40 on the conical washer, i did not, even though it had some rust ) 2. Take the other half off by gently tapping it with a hammer ( photos 1-4 ), tapp and rotate axle 180 degrees, repeat... ( rubber might fall off - see photo for the correct large/small rubber reassembly orientation ) ( no need for the big hammer attached in the photo) Good luck. p.s : A. To take off the sprocket mount, release one front balt of the chain gard and stretch the chain tensioner as far as it goes while chain is off - see photo #6. B. When reassembling remember : the washer has an orientation to it AND the Nut should be staked (since its "wet torqued" with lube it might get free and opened if not secured ) VID_20180707_122501.mp4

Tnx ( I need to replace the break Disc , its under the 5mm spec ) No need to to take out the clamp bolt just for the axle (i decided its better to tighten it before smacking it out of the bearing holder which is held by this bolt) ( https://www.partzilla.com/catalog/honda/motorcycle/2009/vfr800-a-interceptor/rear-wheel Circlip 28/29 are not in the way of the Axle )

Tnx, NO Circlips stated in the service manual just for the axle. ( There is a snap ring if u need to take out the bearing holder out of the swingarm, which i don't)

Hi I Removed the caliper on the right side, stripped everything on the Left side. Tried Biting it with a 600g hammer.... but it does not move ! ( I guess it is seized by a bit of rust , or I"m missing something else that i have to remove ) HELP !!! Any Idea's ?

So Let us know how does the story end ? What was the problem ?

Clear enough, I would add : interaction between front and back is only present when both are applied (tested this empirically - its probably the Secondary Master Cylinder (SMC) on front left caliper functionality(coupling the F & B) ). Empirically Tested : ___ - Apply front brake only- both front disc have the same Hot temperature, rear disc is Cold. ___ - Apply rear brake only - both front disc are Cold ___________________, rear disc is Hot. ___ - Apply both R+F brake - All disc get Hot - Front Left is noticeably Hotter than right.

O.K got U now.

From service manual (6 gen) its understood :front and rear brake are unconditionally combined all the time : (front brake will stop the read even when rear not pressed and vice versa) : " BRAKE SYSTEM INSPECTION This model is equipped with a Linked Brake System. Check ... as follows: ...motorcycle on its centerstand shift to neutral. Push the left front brake caliper upward by hand. Make sure the rear wheel does not turn while the left front brake caliper is pushed. Apply the rear brake pedal. Make sure the front wheel does not turn while the rear brake pedal is applied "

Its been the same unsymmetrical behavior of pad wear for the last 10 years on 2 different 6'th gen VFR800 (the first was fully serviced at Honda central). Left caliper is clearly hotter than the right side ( Don't try this at home- it gets really hot- could get burned especially with sintered pads- use wireless thermometer or slight tap of the hand or gloves) Yes I"m always using the front + rear brake, shouldn't I ? I"ll compare the temps of the right and left disc again but now without the rear brakes.

Is this because of the vfr's integral brake system (combined front left to rear braking system) ?

Service limit is at 3.5 mm. a mechanic told me i could go as much as 0.2-0.3 mm bellow but not more. Does that sound O.K (vfr800A9) ?

Curious, how does this ends ? What was the problem/mistake (4 the lower race) ?

I replaced the pump with a new one after flushing the old coolant with distilled water. Its good as new now. { difficulties: 1) undoing of the cylinder drain bold took time until i found the right tool to get in there. 2) bleeding the air out... } my old 2004 vfr800 (with over 200.000 km) had no issues with the water pump.
