Re: Disc run-out

Heh, In my experience, you will need to see about .1mm / .15mm max run-out to not end p with pulsation at the lever. When you say that the carrier is the problem, do you mean an aluminum carrier that the disc bolts up to and then that assembly bolts on to the wheel hub? If that is the case, you migh...

Re: 750GT Rolling Basket Challange

Still waiting for the warranty replacement Dyna-S to show up. I did get the .85 kg/mm fork springs to replace the .90 ones that should make the ride a bit better. (the .90 ones from Racetech will be going on eBay) Pulled off the drive sprocket to extract the output shaft collar to seal its end and g...

Re: 750GT Rolling Basket Challange

A few more salt bike detail shots: Hereis the air intake duct leading to the air box. There is a filter in the airbox made from a furnace filter element. The air box also has a flapper door that opens before ram air takes effect and closes & seals the box when ram air raises the pressure in the airb...

Re: 750GT Rolling Basket Challange

Things are getting a bit cramped in 'Tom's Temple of Torque'. The red GT on the left came in for getting running and then a list of electrical problems.

Some with the fairing:

The rear lower fairing is not installed. It has to stay off for rear frame support & transport tie-downs.

Re: 750GT Rolling Basket Challange

I get it takes enormous power to generate speed like that,especially on the salt.Is it geared to the moon and needs a big push off as well.Enjoying your posts here,there is a bloke on the Laverda list who builds high end classic cars,Napier's etc for a living.For fun he is doing a couple of Laverda...

Re: 750GT Rolling Basket Challange

hey geodoc, tho' some may find it EZ to laugh at your 'gremlins' suspicion, I concur on more than one occasion, I've replaced a bulb or other minor component in a circuit, only to have another system part fail VERY quickly - I then chase that BS around for awhile until it's somehow 'flushed', and a...

Re: 750GT Rolling Basket Challange

Bad day at black rock. Tweaking the idle last night after installing the #60 pilot jets and it went OK. Then shut it off to answer the phone. Started again to give it a final touch & the idle speed was down from before ....... odd. It had very little fuel in it so put on reserve, but didn't seem to ...

Re: 750GT Rolling Basket Challange

You are probably leaking at the countershaft sprocket/spacer interface. Before you go digging out the seals try undoing the sprocket, pull the spacer and apply 3Bond [Hondabond, Yamabond etc.] to both edges of the spacer and the outer edge of the sprocket and tighten the crap out of the nut. What h...

Re: 750GT Rolling Basket Challange

Just back from a 2 day, 800 km. / 500 mile trip from Vancouver. Went with friend Ian Watson with him riding his '72 BSA Rocket Three. Ran like a freight train - no break-downs, no crashes, no roadside conversations with constable Bob and no near misses with Bambi. Interestingly, Ian's BSA & the 750 ...
