Re: 1974 750 GT with PHF32 jetting recommendation

Here's what I finally ended up using in my '73 GT using PHF32's & Wiseco 'Sport' C.R. pistons after much fiddling and fussing on the dyno and then seat of the pants for final tweaks.

Re: Clutch Grabs Violently on Fresh Engine

Not saying that my clutch problem cure would also cure yours, but. After I got my GT engine back from a complete re-bop by Guy, the clutch stuck & grabbed horribly. I tried all manner of things to rectify with no effect. Finally, in desperation I took one of the steel plates and even though it looke...

Re: Plated cylinders

Most aircraft cylinders are Nickel Silicon Carbide plated on steel bores (not sleeves, but cylinders made from one piece). I had it done at Millenium too and gotten great results, mostly in longevity and reduced fuel consumption. I see that they will do aluminum sleeves for bikes too. I don't know i...

Re: 1974 750 GT carb question

I had a sticking slides problem that turned out to have an off the wall cause. I concocted a Guzzi boy-racer unit with an aftermarket fiberglass tank and one day the throttle stuck (exciting!). I had the (new dellorto) carbs apart probably half a dozen times looking for problems, but it kept happeni...

Re: ‘74 750 GT Restoration in Seattle

Can't say as that I did know it, though the only Bevel guys I actually know are up here in BC, mostly Square Case SS's of one sort or another. Though there are 203 other GT's I know of in the area, mine seems to be the only one that gets ridden much. Actually just got back from a little scoot to my ...

Re: ‘74 750 GT Restoration in Seattle

Amen to renewing or even improving the original electrics. An ST2 Stator / rotor and MOSFET regulator / rectifier is a good thing and ditching the points for a Dyna 'S' is as well. I don't know anything about the later handlebar switches, but if they're original 40+ YO, safe to say they would certai...

Re: Wanted to purchase RT450

https://vancouver.craigslist.ca/rds/mcy/d/1971-ducati-t-450-desmo/6569136184.html $6,900 CDN = ~ $5,474 US Seems kinda strong, but maybe you could beat him down a bit. Being a "competition" bike it might not have a title which would complicate import into the US. https://images.craigslist.org/00o0o_...

Re: 750 GT 4-Hole Solid-Style Front Disc

The measured O.D. is between 274 & 275mm This is the disc I removed from the bike as I got it as a rolling basket case in 2014. I'm led to believe it was last running before it threw the chain through the engine case in the early 90's. It seems likely that this is the disc that it came with as deliv...
