stealth94 Posted February 27, 2012 Share Posted February 27, 2012 Hello there, I'm pretty new to the motorcycle build/rebuilding scene and i was just wondering if anyone out there had some knowledge on the 1986 FZ6. I've been riding for like 6 years now however i never really had the chance of tearing down and rebuilding a bike till now. Current project is making a 1986 FZ6 into a track bike for some of the local tracks in Wisconsin, till i get some experience and then upgrading later down the road. I got it free, it is missing quite a few peices (none too essential like plastics) but it does had a wire mess going on. It also has stage 7 jets and a kerker header with no can. If anyone has any tips on building one of these guys up i'd love to hear it. And if there are any easy swaps that may increase performance that'd be pretty awesome as well. Thank you Oh and does anyone know the stock length of the fork springs? Link to comment Share on other sites More sharing options...
Moderator drewpy Posted February 27, 2012 Moderator Share Posted February 27, 2012 As it happens, I just got an official Yam service manual for the fz600 (in anticipation, thanks Brownie). A 1986 edition no less. stock fork length is 517.5mm or 20.4". min free length 512.5 (19") the engine is an XJ600 and gas flowing and Neta exhaust seems to be the favoured route with a stage 3 dynojet!

Moderator drewpy Posted February 27, 2012 Moderator Share Posted February 27, 2012 Thank ya much good sir. Doesnt say anything about stage 7's though eh? the bit about tuning I picked up off t'internet. I did read that a few peeps have started racing the fz600 in a classification. So in the near future there will be more info out there. Link to comment Share on other sites More sharing options...
stealth94 Posted February 28, 2012 Author Share Posted February 28, 2012 Not soon enough, hoping for a few races/track days this year haha. Would going from stock to progressive springs have an advantage?? https://www.denniskirk.com/progressive-suspension/fork-springs.p58973.prd/58968.sku Link to comment Share on other sites More sharing options...
Moderator drewpy Posted February 28, 2012 Moderator Share Posted February 28, 2012 certainly in racing, need to check the regs though as if in the proddy class there's not a lot you can do! CRMC are the body that introduced the new proddy class for 80's sports bikes. Link to comment Share on other sites More sharing options...
stealth94 Posted March 9, 2012 Author Share Posted March 9, 2012 Know anything about brake pads? I was looking at some on denniskirk but it says dont put these on unless your bike already had them. How do ik if my bike has had sintered or not? https://www.denniskirk.com/dp-brakes/dp-sport-hh-supersport-sintered-brake-pads.p195534.prd/193908.sku Link to comment Share on other sites More sharing options...
