bmwpowere36m3 Posted May 19, 2015 Share Posted May 19, 2015 you're keeping the OEM springs for a guy who weighs 180lbs? Poor choice. OEm is only passable for ~150 at most. 180 should be running .90 as a minimum and .95 would be better if aggressive rider (track use). Frankly a 150lb rider should equip their bike with .82-.85 vs the stock which is somewhere in the .7's. Based on MT-07 service manual, the fork spring rate is 0.87 and shock is ~11 kg/mm. The MT-07 P/Ns for the fork springs are the same as US FZ-07, minus -00 at the very end. The shock (spring N/A) however is a different P/N... I'll be taking some sag measurements soon... but at ~190 lbs in gear, I'll likely need new springs. Link to comment Share on other sites More sharing options...
pattonme Posted May 19, 2015 Share Posted May 19, 2015 There is no way the OEM fork spring is a 0.87. (you sourcing info from here? http://www.motorcycle-talk.net/forum/archive/index.php/t-824.html) It dives far too heavily for that. I would bow deeply and kiss the hand of a Yamaha engineer if they were to have put a 0.85 in there. No Japanese factory puts the right springs in their bikes unless you are ~140lb and even then...

pattonme Posted May 19, 2015 Share Posted May 19, 2015 @bmwpowere36m3 maybe in EU they actually have the 8.5N/mm springs (doubt it) but I don't know if any members here hail from the mother-country. @unknown can tell you there was a significant difference between pre-/post- upgrade in fork dive and going from 0.87 to 0.92 is barely enough for anyone to notice. I didn't keep the original springs I took out, so the next time I get a set I'll put 50lbs on the forks and measure how much it compresses and empirically calculate what is actually installed. It's not uncommon for service manuals to have misprints or be inconsistent with the finalized product's bill of materials. If I'm wrong, I'll eat my hat (and give you free springs).

Don't sweat it.... I wasn't trying to prove you wrong. I know things get lost in "translation" in manuals or their simply wrong in certain cases. On my DRZ-400 I went from 0.44 to 0.48 springs.... I noticed it, but it wasn't huge. However I also swapped the damper rod for cartridge forks at the same time. I'll definitely be in contact as I'll be looking for springs and the cartridge DIY kit.

Premium Member tino206 Posted May 19, 2015 Premium Member Share Posted May 19, 2015 if I confused anyone I had done a full traxxion damper kit on my bike and am installing set gold valves in a different bike a coworker bought an fz after riding mine also afer riding mine with the fork fixed he wanted to try just the valves also for the record traxxion sent .95 spring in my kit and I am 250lbs my coworker is like 180 that is why he wanted to start with just the valves springs can be had if need he will probably never ride the bike aggressive enough to need a full on race set up nor will I, Im just fat Please explain this in stupid terms..you replaced what with what? (links will help illustrate). I am around 230lbs with gear and I would like to know if I have to change something and how I do it. Link to comment Share on other sites More sharing options...
pattonme Posted May 19, 2015 Share Posted May 19, 2015 He bought the Traxxion option under Emulators: http://fz07.org/post/25375 So he replaced the OEM damper rods, springs, added the kit's GVE and put in fresh (15w?) oil Link to comment Share on other sites More sharing options...
gtmn Posted May 20, 2015 Share Posted May 20, 2015 that about says it all except that kit is awesome 1m 250lbs and the bike handles way better then stock very simple install and very effective if you track the bike you may need more but I doubt it installed 95 kg springs and maybe the yellow spring on the gold valve 3 turns in and oil at 110 mm from top so kit goes bottom to top damper rod, gold valve, spring, washer, spacer, washer, cap and oil 110 mm from top was I pint exactly each leg very simple install in fact this type kit will fix many under performing bikes not just sport oh ya Dan at Traxxion is great he also did my ctx 1300 with ak-20shttp://www.traxxion.com/Drop-In-Damper-Rod-and-Fork-Spring-Kit/ Link to comment Share on other sites More sharing options...
Premium Member tino206 Posted May 20, 2015 Premium Member Share Posted May 20, 2015 so that replaced the guts from the forks but how about the rear suspension? or did I miss something.. Link to comment Share on other sites More sharing options...
gtmn Posted May 20, 2015 Share Posted May 20, 2015 nothing on the rear so far in fact I turned down the rear spring to 3 and the bike is better then when I had it on full preload I will probably do a shock on the rear but I just spent 1300 on the other bike also on the forks so I need to slow the spending down this set up made the bike a lot more rideable and no longer pushes through the corners it is very firm but smooth over the bumps and seems to absorb them also it dove like no other bike I ever owned and that is now gone it was very soft on the front before I dint want to take it into a corner it didn't feel right now I just send it in and power out the bike is a blast I think the fork first and test it to see what you need on the rear before you spend on both the rear is not great but it will do for now for me anyway Link to comment Share on other sites More sharing options...
Premium Member tino206 Posted May 20, 2015 Premium Member Share Posted May 20, 2015 good to know, it seems like this is plug and play type of upgrade, I think I will mess with my rear shock and see, I don't really fell any issues with the bike right now so I don't know..it may just be the fact I don't have experience in riding a bike that has been upgraded in the suspension department Link to comment Share on other sites More sharing options...
gtmn Posted May 20, 2015 Share Posted May 20, 2015 I think it came from racetech you only know the best suspension you have ridden it really is cool how much better it can be and I fully under stand mine is still very basic for me this is a play bike and my people mover that gets used more often is the 2014 ctx1300 if you are over 200 lbs the fork needs to be much stiffer for control even if its a simple spring swap and that would take no more then a half hr Link to comment Share on other sites More sharing options...
gtmn Posted May 20, 2015 Share Posted May 20, 2015 I think it was cruizin that said the first money spent on accessories should be suspension, so that the bike fits you and your needs after doing 2 bikes forks I cant even tell you that is the best advice given on the net at 250lbs my bike should absolutely be set up different then a person 100 lbs lighter riding this bike with the suspension fixed or at least repaired is like going from a buick lesabre to a mustang with track suspension if you rode our bikes with a fixed fork you would not hesitate to spend the money by "you" I mean anyone reading these forums good news is there are many guys on this forum willing to help in the suspension areawe sure have a lot of great options you just have to justify the price and how you will ride the bikethese are of course just opinions Link to comment Share on other sites More sharing options...
pattonme Posted May 22, 2015 Share Posted May 22, 2015 OEM spring rate has been measured. see http://fz07.org/post/38634 Link to comment Share on other sites More sharing options...
Premium Member howworkclutch Posted May 22, 2015 Premium Member Share Posted May 22, 2015 I think it was cruizin that said the first money spent on accessories should be suspension, so that the bike fits you and your needs i have a friend who has a supersport with ohlins front/rear setup for his weight. i'm a little heavy in my gear, but not by much. that bike makes me superman. i can hop on it and burn a lap across my favorite mountain road and go like stink. but to me, it doesn't feel like i'm going like stink. it feels mildly brisk. if i follow him on my bike, its drama. nothing but drama. i can't stand sport-riding the fz07. so whoever said that is 100% right. put your money in suspension first. -HowWorkClutch Link to comment Share on other sites More sharing options...
