    Five Minute Fix – fragile fixings

    by

    โ€“

    Words/Pictures by Steve Cooper Once in a while thereโ€™s a need to tight a nut or bolt on something thatโ€™s small, fragile or mounted on a surface thatโ€™s easily damaged. If youโ€™re not careful the fixing ends up either not sufficiently tight or the surrounding material gets marked. Even worse you over tighten then snap…

    Your Tips – TY250 yellowing tank

    by

    In an earlier edition of Q&A Lee was asking how to restore the yellowing plastic of the petrol tank on his TY250. I had a similar issue with the expansion tank on my CX500 restoration. I ‘borrowed’ some bleach from under the kitchen sink, made up a fairly strong solution with water and immersed the…

    Q: I have installed a racing exhaust on my W650, which is pretty much a set of empty pipes/silencers, but did not re-jet (I wasn’t interested in the supposedly four extra bhp it was said to provide). It’s LOUD, and the backfiring was wild at first, but 3500 miles / 5500kms or so later, it’s…

    Q: Hello! My son is living in the USA and he is in the middle of fixing up his 1984 ZX750 GPzย ย A12 American spec. He wants to know the torque setting for the bolts holding the drive chain sprocket on the rear wheel. He has set them at 29 ft-lbs, but is unsure if that…

  • Five Minute Fix – remove paint from threads

    by

    โ€“

    Words/Pictures by Steve Cooper Weโ€™ve all been there; the painter or powdercoater forget to mask a thread. Taps and dies are good on smaller threads but what about larger ones? What if youโ€™ve already fitted key parts and access is limited? Fill the back of any holes or spaces with clean rag and add masking…

  • Suzuki GS850G crash damage

    Q: My bike was involved in a crash and came down on the right hand (timing cover) side. All theย electronic ignition pick-ups have been replaced by a previous owner with parts from a GS1000. I am not sure whether the black box was also replaced to match. The bike starts fine, but will not rev-out…

  • Your Tips – paint your wagon

    by

    โ€“

    In the October 2015 edition of CMM a chap called Rob Neal wrote about high-temperature paint for his CX500 well, I have a similar vintage CBX1000 and have used VHT silver spray paint to good effect on several of the casings and it looks great despite not being applied by a professional. While in the…

  • Five Minute Fix – finding small parts

    by

    โ€“

    Words/Pictures by Steve Cooper Dropping a fixing into a bike is a pain with ages spent crawling around to no avail. Rather than waste time stand back, take a deep breath and then put something cushioning under the bike. Often just taking the bike the stand will cause the screw, washer etc. to plop onto…

  • Advice on nuts and bolts

    by

    โ€“

    Q: Can you tell me how to tell if a nut or bolt is usable or not.ย  I think I over-torqued a bolt/acorn nut combination due to using a cheap torque wrench which didn’t click. Note to self: cheap tools cause more problems than they solve. Tommy G, USA ย A: It has often occurred to…
