    Tank bolts

    Though I can't find simple descriptions in English but, I show one resource. Stainless steel has larger gap with alminium more than between steels and Aluminium. I don't make sure screw hole seize will appear with just the cause of galvanic corrosion or not, you can predict handling of stainless...

    Allow my this reply for riders safety Just thinking the corrosion on stainless screw or parts, I almost agree with you. However, waher looks made by aluminium and, how about screw hole of master cylinder? Corrosion of brake system is one kind of most scare one for me. Putting grease would work...

    Tank bolts

    Allow my intrupption, I wouldn't think use stainless bolt is better idea. Aluminume side(screw hole) will has corrosion by galvanize though I dodn't check finish of screw hole. If you need to use stainless steel bolt at aluminium or steel part at temporaly use, ptting grease will makes it...

    Tank bolts

    OEM bolts are M6 and around 20mm length. Also washer is preinstalled in bolt. Refer to lazamus69-san's comment, why dont you order OEM?

    Brake Caliper Modification for 06 model fz6?

    Lewis-san, Thank you for your concern. There are many Japanese riders that they keep the condition of old bikes. For exhample, FZ750 and XJ900 XS650 FZR1000 non-exup, FZR1000 etc. Especially, FZ750 has very poor caliper and damn ventilated rotor.... Many people swap using FZR front end...

    Galfer? (galfer responds)

    Excuse me....... . Why use stainless steel? To think well electrical corrosion, Stainless steel never have good combination with steel or aluminium unless any plating because combination between SS and Steel or Alminium produce large electrical gap. This voltage gap work for material corossion...

    Brake Caliper Modification for 06 model fz6?

    For the people who has later FZ6 and want to use brembo caliper, there are YAMAHA OEM brembo(licenced production; we call Yamambo). It is XJR400R XJR1200, early XJR1300 one have 100mm gap. Some people say better than FZ6 OEM Sumitomo.

    Brake Caliper Modification for 06 model fz6?

    You should check GSX R one with measurement. It is not ordinaly that they have 83mm. Usually they use 89mm Nisshin. I think brembo has 40 or 65mm gap on 4pod casting caliper. Another choice?? How about Belringer?

    Brake Caliper Modification for 06 model fz6?

    Yes. I suppose to need to take matching with master cylinder and also sent him the parts list of master cylinder on each model. To prevent slip down at panic brake, need running consideration of mastercylinder and pad combination. Actually, I don't know the piston(pod) daimeter of early FZ6...

    Brake Caliper Modification for 06 model fz6?

    If I were you....... I'll choose 4 pod casting brembo with bracket........ nono just kidding:D I agree with using OEM products because expendable supplies(Seal, piston) are provide for decades. Additionally, Triumph (Speed triple) use 83mm Nisshin with "Triumph" logo of surface!!! I guess...

    Brake Caliper Modification for 06 model fz6?

    FZ6 early model has 83mm pitch mount and, later model from '07 has 100mm(Sumitomo MOS64 Series). I could recommend you to use TZ250(racing bike) caliper (made by Nisshin). Probably, it will has too strong stopping power but, we Japanese geeks prefer to use Nisshin than Sumitomo because...

You can see this kind of 4 digits besides of tire on every tire (each manufacture). Incidentally, tire maker recommend consumer that need to replace...
