Back in 1973 I bought an RD250 from the horrid bike dealer Gambier Reeks. I holed a piston and dropped in a 350cc engine rather than repair. The RD I had was the round tank edition with blue paintwork. I was young and naive with no mechanical background (then)... so when the small ends went, regrettably I sold it and bought a 500-4. Later, in 90's I bought an FJ1200 and kept her for 13 years, an awesome bike she ate consumables but was a 'rocket sofa' LOL.... I had several bikes over the years, too many to mention here - eventually I succumbed to getting onto a BMW GSA Adventure - it was stolen and I saw sense decided to be more practical, thoughtfully got an XT660z (second hand of course). She goes everywhere with me, I am off to Norkapp and also, later this year to Switzerland. We went to Berlin in January before C-19... Yamahas have SOUL and are not ridden by berks, in the main scheme of things. I have ridden, despatched, taught and worked on bikes for 45 years now... 1995 R1100RS sits in the garage (want to sell her), next to a 1984 R80RT I have had her for last 30 years! So - nice to be her, cheers, James

@Noise; Surely you can answer him? The poor guy wanted info... Yes, I too have an Xt660z 2010 and have fitted a power commander (with O2 sensor) also DNA air filter. It definitely makes a difference but it would be fine without. It is best noticed when in lower rev range but you might feel a little more inclined to use the throttle more and increase petrol use accordingly! Maybe get it set up properly on a dyno, I am considering doing that. (£200+) - you need a Windows PC to set it up, dont forget...
