There is no "sort of 2007ish". The 312R was made in the 2007/8 model year only.

Rear Hub, Fuel Lines, Air Box Wellnuts are the major contributors to issues. Bleeding the rear brakes well and keeping the coolant at the minimum mark wehn cold are other niggles. Switch to Engine Ice.

There are minor issues mostly catered for by knowing your bike and keeping it in a good state of service.

If I bought one of these, ( and I used to own this model ), I would service the hub and consider upgrading to a stronger Hub ..There are details on the forum.
I would given the age change the internal and external fuel lines for new...and possibly change the eternal elbow connectors for USA made CPC metal ones ( Not from Far East ). I personally believe that most problems with the oe plastic elbows occur through rough handling of the tank on removal straining the connectors and causing cracking...You won't know !

The major area I would recommend addressing is the ECU which is set to weaken the mixture at approx 5000 RPM in order to reduce emissions for Homologation under test ( VW were alot more sophisticated ! )
The problem is that 5000 rpm is a sweet area to ride along on the road and is just at the rev where I open up to overtake a vehicle in front....Not a great place for the bike to lose power...

I have had an X Bikes tunes Microtec ECU fitted which gets the best from the engine and removes this flat spot.

I believe there is a fix for the oe Magnetti Marelli 5SM available ( Chuck ? )

and ..not pushing my own wares but it's a low cost strategy to fit a Stainless steel radiator Support bracket to reduce the sagging in the radiator which are known to crack and fail.

Replacing a couple of airbox Wellnuts with Rivnuts is also highly recommeneded.

I loved my 312 R....I sold it as I had two F4s and I would have another definitely.

Get it !

USA 312R's had the upgraded cam chain tensioner. Don't know where you're from but I'd check that out.

Rear hub problems are generally related to over-tightening the pinch bolts at rear of swing arm, and improper chain tension (too tight)....that and simple lack of maintenance.
Serviced properly and not stressed from over-tightend caused distortion, the rear hub is fairly reliable. Many have not had any problems, some have.
A more robust design is available from Mitchy down under.
