No rush - the machine shop guy is away for a week anyway !

Thanx - we took a flyer with 24mm - worked spot on.

re:the APE stud sets - do you think they might be persuaded to sell the 4 studs we need as a kit ? They already make them so would be another market outlet for them !

Work is progressing with the twin plug head conversions - the jig is made [ machine shop ]. I am debating whether to use 10mm or 14mm fo the second plug. Either way the conversions I've seen done so far have left the thread exposed where it follows into the combustion chamber contour - in my view risking a local hot spot .... especially with NOS / Turbo !

The uprated [ 20% ] clutch spring samples are now made - just waiting passivating. I have to get 100 ordered, but that's "only" 25 engines - and I now have 3 !

It would be nice if we could persuade APE to come up with the stud kit. Do you have an address / contact for them ?

You need 8 studs of 2 different lengths. . The 1000 uses 12 studs of three different lengths,  so if you buy the 1000 stud set you end up with 4 studs that are too short. APE might sell you a stud kit, sans the 4 studs you don’t need but demand is virtually non existent for something like this so I would be surprised if they would. You also need their longer head nuts or through nuts to compensate for the slightly longer head studs. Their contact info is at http://www.aperaceparts.com/

Yes, understand re: the lack of a huge market !! - but as they already make the parts ...... worth a try. Thanx for the link, I'll contact them Monday.

WOW - result ! I contacted them and they are willing to sell me the parts needed as a kit.

Depending on price I have 3 other people in UK / Germany interested in kits. I'm trying to get an order for 5 kits - then I can ask for discount !

Can you confirm the length [s ] of the studs required ? When I confirm that they will give me a firm price.

Appreciate your help.

Man you keep getting me at the worst times. I just moved at the beginning of the month to a new two car garage. Everything is still packed up at the moment. Its gonna be a second until I can locate the parts. I do remember that the bolts I did not use from their kit were the shortest ones. hopefully i will have a chance this weekend and dig through  my boxes of parts

No rush - sorry to catch you at a busy time !

I'm just glad I got a positive response from APE. In fact they seemed to be quite interested in my project !

Unusual these days for a big company to take time to deal with an enquiry which by no means will lead to substantial orders !

But if you give them permission to put pictures on their site etc of your bike with the blower and their studs holding in the pressure that's some great marketing material.
