I had a succession of across the frame 4 pot bikes. Then I traded a ZZR1100 for a Ducati 900SS and was then forever a V-twin man. Just loved the torque and drivability, also the elegance and simplicity of the design.
I could never understand why Tamburini put a 4 cylinder in the MV.

The F3 is a 3 cylinder 675 engine, I assumed it was a Triumph lump from their Daytona and Street Tripple but looking closely I'm not too sure!.

Have you ever riden a 2010 onwards Yamaha R1 "big bang" (cross plane crank)?. Remarkable engine, the low down grunt of a V twin but revs like an inline 4. In all my 20+ years of spannering that engine and power delivery really stood out.

A real peach of an engine.

No, never did. I’ve heard good things about it though.
They did summat similar years ago, with the TRX850. Hailed as being a competitor for the Duc L twins.

They are a great looking bike, very similar styling to Ducati (was it the same bloke who designed the 916?).
Think you are right, would love a 916 but hey the 748s is ok by me !

I have whole packing line to service today while it's quiet so time to do those jobs that have been building up.
Promotional label applicator, the loom between the control box and labeller, the flexi conduit has deteriorated.

Cut away the damaged conduit, shorten the 16 wires as there's now very little room to accommodate the surplus in the socket

, tidy up and refit.

Nice to get the niggly stuff done. Got a damaged 3 phase isolator next.
 
Graftin' in the sunshine :sun:

I had the joys of drilling out three pilot air screws today (brass screws in aluminium carb bodies).

Managed to get them out without ruining the threads in the carbs.

Have advised the carbs needed sorting out over the last 3 or 4 services, wish I'd have kept my bloody mouth shut in hindsight!.

Seem to be having a run on carb jobs!, YZF750 this time. Had to drill the pilot air screw anti tamper caps out (joy!).

Ran sweet as a nut!.

Also had a lovely Kawasaki GT750, fully restored but ran like a bag of spanners, couple of hours fettling the carbs and it was a completely different bike.

It's going to be a lost art soon, all laptops and diagnostic kit for the new bikes...

I passed my bike test, and 30 minutes later I bought a Kawasaki GT750. After a 125cc Yamaha it felt like a fire breathing monster! Mine was a gold one. Kept it for 2 years and upgraded to a GPZ900R, the original Ninja :becool:
