It's not a huge difference but noticeable, as the revs rise the midrange pull is harder than on the 620, and it pulls strongly to higher revs after that. I fitted the pumper version of the standard carb (which used to be on Harley or Moto Guzzi) so it instantly squirts petrol on the turn of the throttle, without a digital brain calculating if it is dangerous to do it first of all or not
The vibes can be draining after a couple of hours though, that would be my main reason for changing it, I might have one last go with getting the seat gelled up for more comfort though.
It's the mere 142kg of weight which really makes it something fun to ride.
The fact the oil tank is in the frame and having two oil filters just makes it more interesting to bleed the oil after an oil/filter change
Â
The 690 is on my radar, I would probably only ditch this 640 for a 690, I keep looking at the mk1 2008 model, and just lost out on ebay on one for £2250 in fact, I'll try again on the next one that comes along.
Â
Basically the 690 has significantly more power, torque and a much needed 6th gear, together with a second balancer shaft to smooth it all out, at the expense of not much more weight at all.
A supermoto 690 on sticky tyres beats almost anything on the twisties around here, apart from another supermoto.
Â
It's a class of bike I never thought would suit me, and the 620 was just a mad experiment to to see if it lived up to the description I read about it on a website - "DO NOT BUY THIS MOTORCYCLE "Â ( https://www.motorcyclespecs.co.za/model/...e%2097.htm). They were right, it's one of the cheapest entry points into hooliganism there is, I should have left it alone...
That's a tidy XJ. I couriered mine for 60,000 miles with hardly any bother. Haven't seen a front fairing like that before, but it looks like the headlights are an improvement on standard !
Original 80âs PowerBronze, only 1 I have seen, previous owner built the frame himself.
He's been helping a mate with a turbo Busa which was recently just pipped for an NZ Land Speed record by an Kawasaki H2R.
Â
Some of the madness has rubbed off. He was around yesterday telling me about electric turbo's which spin up to 35'000 rippums. Once the top end has been stripped and checked he will make the call on traditional or electric.
TDM 850 Loud and unusual. CRM 250r Woo hoo! DT 230 Lanza Fiddled with.... Bloody hell, is that legal? GG Randonee AKA "I didn't think that was possible".

The TDM was beat when I got it but I still thought it was great.
Now all new top end, comparing how it runs to how it ran when I bought it, I will never need another bike.
Just bought 2 bikes and had them delivered on Monday. A 1991 TDM850, 6,700 miles, all original and a 1981 XJ650 shaftie. Both need work so should satisfy my fettlin' needs for a good while.

Off topic (not really).... mancave needs treatment (and a door), by the look of it.......Sadolin durable.... not cheap but lasts years (applied 2 coats to my new shed and it's still good 7 years later), much better than fence paint.

I was helping Mole get some of Wicky's bike stuff sorted and the mk1 kinda grew on me as I worked on it, had to have it.

Â
5 fookin gears not 4.5 eh. Mk1 needs a deep clean and a few jobs, paint fork lowers, sort out fuel lines etc, depending how far I want to take it really. The Xj650, I'll probably just get it running sweet, sort out any mechanical needs, give it a good clean and run as is for now.

Been thinking it might be a good bike to take abroad.
