New project- Guzzi NTX650
« on: December 13, 2024, 02:53:12 PM »
I've been looking for one of these for ages and finally got my hands on one this week, it's a rare 1987 Moto Guzzi NTX650. These were never imported to the UK at the time as their plastic tank wasn't legal then, but a handful have bee imported privately since then. This one looks rather rough but apparently mechanically is ok, it certainly needs a good clean which I'll hopefully get onto tomorrow. The rough plan for this project is to get it running & ride it a bit, to make sure it's ok and I like it, then sort out the cosmetics- full paint job etc., though I'm curious to try out wrapping so that may happen.

I'll try to update this one as I go. My last  2 projects were a BMW R100RS which I did a write up on it after I'd sorted it out, and a Kawa H1 which was never meant to be a project, the auction's claim of it being restored wasn't too true and I ended up discovering loads of work to do.

That's a cool bike. Moto Guzzi motors have a bunch of torque. Our 90' Moto Guzzi 1000 Le Mans tries to throw itself over on the right side if you blip the throttle at the stoplight. 8)

Subscribed, always wanted a Guzzi! 

Can't find one for sale here in the States, guess it was not imported here?

A bit of progress to report. I cleaned it at the weekend twice, it seriously needed it, the amount of ingrained grime was amazing. I gave it a good go with various detergents on Saturday, then took it for a ride later, then cleaned it again with traffic film remover on Sunday. Looks better now, the wheel rims are particularly good, I didn't discover much else either, other than spotting that the speedo drive is  free moving & only stopped from spinning with the wheel by the cable anchoring it. Bit odd that.

I gave it a check over- all fluids ok, oil looks fairly fresh, front master cylinder lid hasn't been off for years, I was relieved when I got the 2 seized Philips screws undone without damage. All chassis bearings seem good. Fork tube chrome is really good. Calipers aren't seized, that makes a change for me. 
 
Riding. Ok it's a sod to start from cold. Sometimes. But I'm onto that, I think it is due to several problems with the choke cables, plungers & lever.  The engine sounds good, rides well and pulls up to 80+ swiftly, though doesn't feel very right at all low down, I suspect the throttle cables are miles out of sync. The clutch works aok too, and I was pleased to discover all gears are present, after my project BMW's test ride a couple of years ago discovered that it had a neutral instead of 5th.

 The handling felt dismal though, most unpleasant turning into corners, the tyres are pretty worn and a check of the date codes shows them as 2003 vintage. I work with people younger than that. So new ones are called for.

Also called for is some electrical attention- check out the battery terminals in the photo. If you look closely at the +ve one you may be able to see that extension/ busbar has 4 or 5 wires attached to it.  All the more exciting for there being no insulation and no fuses.
