Re: Jetting and needle for PHF32s on stock 750 GT

Heh James, I've got a 750 GT that was recently brought back from a basket case that has Sport pistons and PHF 32's, but otherwise stock for mods that would effect jetting. I started out with the jetting specified for the 750 Sport: MJ 125 NJ: 265AB PJ: 65 Needle: K5 Slide: 70/2 Variables are - Chevr...

Re: 750GT Rolling Basket Challange

The weather here in Vancouver is starting to get more like what we all block out of our minds as soon as Spring gets here - like winter never happened. It's the season for the record for most consecutive days of rain (33) and getting close to that is not unusual at some point(s) during the next six ...

Re: 750GT Rolling Basket Challange

Well here's a coincidence. A friend (and author) that I go sport-motoring with from Vancouver, just sent me an email recommending a boook: The Flamethrowers by Rachel Kushner: http://www.goodreads.com/book/show/15803141-the-flamethrowers The year is 1975 and Reno—so-called because of the place of he...

Re: 750GT Rolling Basket Challange

Another leak from a casting flaw. A judicious application of JB Weld and it should be sealed up. Found it with oil dye and black light flashlight. That stuff is fantastic - 1st time I've used it. https://i.postimg.cc/LJYbfv9f/leakfix.jpg (road test) Took it out for about 120 km. hither & thither and...

Re: 750GT Rolling Basket Challange

I'd heard that there were self-locking, nylock output shaft nuts available, but had a hell of a time finding them. They are available from Maryland Metrics for about $9.25 each, P/N GUK7. http://mdmetric.com/ I got a couple and tried one on the stock sprocket nut socket only to discovered that the s...

Re: 750GT Rolling Basket Challange

Installing aluminium tubes should've solved the problem . They expand more when warm, sealing better. However it was (is ?) difficult to find tubes with a 31 mm OD, so most turned down a 32-3 mm tube, maybe the OD isn't the same as standard. I found some standard 30-2 mm tubes and turned the INSIDE...

Re: 750GT Rolling Basket Challange

The turn usually does the trick but as Steve said the grooves need to be clean and the o rings resilient. Not being the trusting sort I use a thin coat of the non hardening Permatex Aviation sealer- the brown brush on liquid - on the end of the tube before I install and carefully wipe off the tube ...

Re: 750GT Rolling Basket Challange

These are 1 of those things that you really must pay attention to, newly rebuilt doesn't mean all the crap got out of the grooves.... Every little bit must go. Also, the orings used could have just been too old and hardened to work. Well I guess I'll find out when it comes apart this winter. Got to...

Re: 750GT Rolling Basket Challange

Perhaps the problem is with the aluminum tubes. From my experience the standard steel tubes work well. Bruce Others with chrome or stainless ones seem to have had this problem too. And can't imagine why, if the aluminum tubes are the same dimension as the chrome ones, there would be more of a leaki...

Re: 750GT Rolling Basket Challange

OK ..... my 750 GT is running great, but it has a few irritating oil leaks. I recon that the one I'm chasing in the counter-shaft sprocket area is from a porous casting and waiting for oil dye to track that one down. The other ones are coming from the top of the bevel shaft tubes. I tried rotating t...

Re: 750GT Rolling Basket Challange

Went down to the Vintage Motorcycle Festival at the LeMay Car Museum in Tacoma WA this past Saturday. There was a clutch of Bevels there, among which was the 80's Tunstall racer: https://i.postimg.cc/3d68jSTF/lemay1.jpg https://i.postimg.cc/5jKb176W/lemay2.jpg https://i.postimg.cc/McYJLth4/lemay3.jp...
