i wouldnt bother with re chroming the raygun silencers as ran my triple with them years ago. the metal is so thin they eventually blow around the outside top of the silencer due to the heat cycles. there was a company in new zealand making fine replicas but i dont know if they are still around.

i had exactly the same issue as the original post with a bsa a7 7 " single sided  rim. spent ages on build. tried reversing the rim with little change and one set of spokes were too long and another slightly too short. i should have sent the whole thing back but i was desperate to get the bike on the road and settled for a bodge job. i was copying the same bsa spoke pattern and i found a post on another forum that had the same issue as me . it seems the rim producer i bought from does not necessarily use the standard rim spoke pattern but can have their own version. my fault for not consulting the manufacturer but a lot wiser to the pitfalls .
on the subject of wheel building , about 30 years ago i went to vic nunns in surbiton [ wheelbuilder ] to buy some replacement broken spokes on my trident and what the friendly old boy did was match the spoke size and length and then hand tap the curl on the end of the spoke  on his old blacksmiths vise. it took him seconds to bend each spoke perfectly.

i have yet to buy a rim for a bsa that laced together perfectly like an original dunlop. recently i bought spokes and rim for a super rocket full width hub and the drilling was perfect and laced up really well. however the dimples in the rim were not as central as the dunlop rims and i had to grind some of the spoke nipple as well as the protruding spokes to give a smooth rounded surface for the inner tube. another issue is being supplied with larger 4mm spokes rather than butted spokes that meant the spokes were never in contact when they cross. if you question anything with the manufacturers over the phone they can bounce you by telling you to take it to a  wheelbuilder with years of experience.
without dunlop and the original jigs i guess its all a compromise replacing rims.

hi dave,
with my b31 handling issue i changed head races ,front tyre, fork springs then added rebound dampers which all helped but i saved the worst for last and swopped the swing arm bearings for needle rollers and cured.
recently on my a10 i had a horrible high speed veer to the left which i thought was wheel bearings but turned out to be an old tyre on the front wheel. it looked perfect but i suspect didnt like getting warmed up.
nothing worse than poor handling on a straight road at high speed.

hi dave, i found fork rebound dampers helped one of my b sa with poor handling. a b31. however the eventual problem was found to be worn swing arm bushing. since i ve gone to needle rollers and bobbins and am now happy. the stiffer front end is better than bouncing on the front springs as you potter along and any other issue like i had makes it worse.

Twins / Re: a65 coil brackets unobtainium
« on: 11 May, 2022, 23:11:33 »
just to update if anyone was interested. after making these brackets i found i didnt have the right coil clamps. also they looked clumsy in place. so i drilled a hole in the cross over bracket for each commonly sourced coil clamp to fit with a long bolt and spacer. a lot simpler and hidden by side covers anyway.

thankyou for the dimension drawings spaceman.
however i m a little confused why both brackets are so different.do both brackets locate the horizontal panel mount bracket? which holes?
as they are missing its hard to figure out.

Twins / a65 coil brackets unobtainium
« on: 28 April, 2022, 22:14:19 »
hello,
almost completed my mongrel 66 a65 with an oif engine project.
i have a65 side panels ,cross over bracket , but somebody nicked the coil brackets 68 9278 and 9279.
having rung around the usual bsa dealers and trawled internet i realise i will have to make these from scrap.
so could anyone be so kind to give measurements ?

hi, checked my notes.  i ve used 4043 rods for small welds on bsa crankcases as they were free with the welder . i spent a lot more time on cleaning and prep than welding. there is another rod preferred by other welders which i cant remember but 4043 rods will weld.
i recommend a search on u tube for advise.

hello,
impossible to diagnose that fault from emails.
i ve heard the saying on forums that most carb issues are electrical and vise versa.
i am having similar ongoing issues with richness even with electronic ignition and suspect its the latest fuel.
have you checked the fuel flow from the petrol tank is good? new petrol? is the petrol being contaminated with water from the petrol tank? drain the carb and check the jets are clear.
the next option is to substitute a good working carb and magneto.

« on: 04 March, 2022, 22:01:19 »
there has been many posts regarding bsa a7 a10 factory replacement frames .they are identified by having rear brake cable brackets and rod operated brake lever hole. i should imagine all the frames left in 1972 73 were oif a65. and the receivers still managed to cobble some bikes together for sale.
