not concerned at all
however, those footrest mounting bolts are probably the best looking bolts on the whole bike, imo anyway, so i'd like to go the original way if i can
been to the atomic wreckers in ackl, they don't have it, but still have a few places to check before thinking of alternatives
cheers

Its paid for itself already - its only chinese crap but I still managed to cut a fairly long thread on an A2 M10 bolt.

i actually have a set myself, but not the m10 fine, and just thought i want to spare myself trying in hurry to find one to buy + spending money on it right now
mind you, that price is amazing (even if it was only a disposable set!)

found the bolt i need, at atomic wreckers
it happens to be 5mm longer than the original which is just perfect as i now just need to find that tap and make the thread in the frame a bit longer (and there is enough room to do it)

so, with no luck finding a fine threaded m10 tap to borrow, would someone maybe know where i could buy it?

ps
i was after a high grade steel fine threaded m10 lock-nuts some time ago and couldn't find them anywhere, in like a dozen major places, so i'm worried this search doesn't take the same route...

A decent engineering shop - wairua engineering or blackwoods and Paykel will have them - only problem is they will be real high quality and probably as much for one as a whole set of crap chinese ones. Bummer.

thanks, i've seen them. would be a nice complement to my work, but financially it's not the right time for me...

blackwood quoted me $47 for one piece
so, i scored a 40 piece set off trademe for $26

i now also have taps and dies as small as M3x0.5, not sure what to use them for though, maybe to fix a fine swiss wrist watch ???

having re-coiled all the crankcases some time ago, i now re-coiled the remaining dodgy threads in the cylinder head, etc
i thought i should post my finding as it may be useful to other people servicing older bikes

with most engine threads the problem was with the threads in the holes rather than on the bolts (as the parts are alu alloy hence softer material than the steel bolts)
what i found however is that once i re-coil the holes i start having problems with the bolts...
i snapped a bolt or two trying to test-tighten them to a proper torque (in a re-coil insert), the bolts that seemed fine at first
(the thread in the bolt actually remains intact but the bolt snaps just above the coil insert)

so, the narative is to ideally replace the bolt (if old or if of crapy material) whenever re-coiling a thread

finding suitable m6 and m8 flange bolts is proving a major difficulty though

Have you been to MSL in Avondale, or maybe the fastener shop in Constellation Dr, they may be able to help.

thanks, yup, tried both places. i've been through this before... the retailers end up calling each other to see if they can get what you need from someone else

champion parts melbourne (available at repco, etc.) do high tensile flange bolts but finding the right lenght is difficult. i may have to buy longer ones and cut them

**psyguy** · 17th May 2007, 20:31

atom fasteners east tamaki have a limited range of m6 and m8 flange bolts, so i bought a few i need for inside the engine
they are high tensile 10.9 grade

other than atom fasteners, the only other flange bolts i could find come from champion parts melbourne, distributed through repco and some other places, but their availability is scarce (and they're sold in packages only and sometimes come only together with the nuts)

however, i think they are the best oem replacement available at least as far as the looks go (they are high tensile but would still need to be chromed to eliminate rusting)

everyone told me to stay away from this guy when looking for parts

but he was the only one who said he actually had in stock the pistons i'm after
i placed my order nearly 5 weeks ago but it got misteriously cancelled a week later, by a "glitch in the computer system" as he called it
then, because of the same "glitch" i couldn't place another order for another two weeks
he wouldn't accept paypal payment even though that's a listed method of payment on his website
he also wouldn't have me give him the credit card details over the phone

since i finally placed the order two weeks ago he hasn't been responding to my queries regards the order status, other than to say he was out of the office (and "out of the state on a personal matter") but would get in touch upon his return...

so, i still don't know whether those pistons really exist in his store...

you guessed, i'm a bit

by now

**psyguy** · 17th May 2007, 21:05

no, she's not finished, i just provisionally put some bits together to get enchanted each time i walk into the garage

**psyguy** · 17th May 2007, 21:16

with the oversized pistons still being the unknown:

i took the block to the shop for honing and planing and will for now install the standard size pistons with new rings
the valve clearances are all done as are all necessary heli-coils + a few new bolts

the bottom end has been done for some time now, so, prety much i should be ready to start putting back together the top end some time next week

the new airbox boots are on their way from the usa

(as are some other bits i could not resist not buying in the same go

)

**psyguy** · 18th May 2007, 19:42

as always, help much appreciated...

1.
the service manual says to fit the two top rings so that the stamped letter "R" faces the top
my rings are aftermarket and stamped "N"

do i still follow the same logic?

2.
the photo below shows the cross section of the original two top rings
my second ring however (to my eye) is square in the cross section (and not angled as in the photo)
