Barge like handling - Stinka - 21-02-19 So I need to do some serious tweaking to sharpen up the front end on my gen 1. What are the limits of raising the forks through clamps before it’s gets a bit slappy? I’m thinking I’ll go for 15mm straight away as it’s so slow to tip in. Loads of dive under braking and the preload is pretty much all the way out, I’m 23 stone lol so I’m going to need to wind it right in a fair bit me thinks ... any suggestions? Re: Barge like handling - Dudeofrude - 21-02-19 To be honest I doubt there is much the standard forks are gonna do with 23 stone bearing down on them. You have to remember these bikes are all design in Japan for people that are 5ft 5 and weigh 8 stone haha I'd be more inclined to rebuild the forks with heavier springs to suit you. If you can do the job yourself then really isn't that expensive :thumbup Re: Barge like handling - ogri48 - 21-02-19 mate you wouldn't believe how much difference a clean and fresh oil will make to your bike. Ask Dynspud too, once hes had a chance to get a proper run on his recently refreshed front end thou. ![]() Re: Barge like handling - Falcon 269 - 22-02-19 I agree with what's been suggested to improve the forks (heavier single-rate springs, new oil etc) but you need to address the rear shock first. It was also designed for the tiny rice eater who tested the bike and is good for a 13st rider in gear. That's when new so by now it's well past it's best. With the rear sagging so deep, you will never get the front end weight bias you desire no matter how far through the yokes you pull the fork legs. ![]() Re: Barge like handling - stevierst - 22-02-19 You need a bit of fresh springing Stinka! Makes a huge difference to how the bike behaves, it did with mine. As for fork dropping through the yokes, I did this, and it certainly sharpened up the steering, but made the bike ‘flop’ into bends which felt a little odd to me. As an alternative, I put the forks back to normal, and raised the rear 2”. It cured the flop, kept the neutral steering, and made her a hell of a lot sharper on the twisties. Might not work for everyone, but I’m built like a giraffe with very long legs. Just my 2p worth. Re: Barge like handling - Stinka - 22-02-19 I have the s1000rr shock to fit when I can get around to it. I’ll probably get ktec or someone to redo the forks after that. Anyone decent in the midlands to do my forks ? Re: Barge like handling - Old-Git - 22-02-19 (22-02-19, 12:34 PM)Stinka link Wrote: I have the s1000rr shock to fit when I can get around to it.

Dropping the front will only make it turn in faster, the Fzs1000 has a tendency to run wide out of bends especially when giving it the beans and dropping the front won't fix that, it needs a lot of work to reduce/stop it. It can be done with just upgrading the fork springs and increase the the fork oil to 7.5w minimum, playing around with the compression and rebound damping, but is a slow process I have noticed over the years that oils from different companies do not work the same even if they have the same weight markings.

Running wide out of bends is exactly it ! I’ve wound the preload in to no rings showing and it still dives badly. Using 110mm of travel on spirited riding with some hard braking. It seems the first 2 inches of the spring are just pure sag and slop , maybe someone put progressive springs in at some point. Either way they’re pretty shagged, time for a rebuild Re: Barge like handling - Stinka - 22-02-19 https://youtu.be/wUuv2U_Ie7c Looks very easy tbh. My best pal is an engineer and I reckon we’ll piss that between us Where to order linear springs and oil from ?

I changed mine to stiffer wilbers progressive, but still found the soft setting to soft but not as bad as the originals. I did not go linear because I go two up a lot. With the original springs and original oil (which is about 5W), I used these settings to start (I'm about 13.5 stone with all gear on) Front: drop forks 5mm through yokes. Compression: five turns back from max. Rebound: six turns back from max. finally took it in to 4, improved the running wide a bit. Preload: maximum no rings showing. With Wilbers and 7.5W oil Front: drop forks 10mm through yokes. (12 to 15mm made it turn in top quick with the Sportec M7RR) Compression: six clicks back from max. Started at eight and worked back Rebound: four clicks back from max. Started at 8 and worked back Preload: maximum no rings showing. I found that the rebound had more effect as I felt it appeared to be rebounding too quick and causing it to run wide, by slowing the rebound it improved. The problem was I used different make of oil last time and my original settings before that no longer worked. A word of caution when putting the forks back together if you strip them, set the rebound adjusters off the bike to half way, it is around 40 clicks from soft out to hard. Otherwise you may end up not being able to adjust it properly when assembled. Otherwise you may not be able to adjust them to full hard, I found out the hard way :'( Re: Barge like handling - Stinka - 22-02-19 Cheers for that mate ! More tweeking required in the short term, before I tare them down and start again Re: Barge like handling - unfazed - 22-02-19 :thumbup Re: Barge like handling - Mustang - 23-02-19 (22-02-19, 01:50 PM)Old-Git link Wrote: [quote author=Stinka link=topic=24967.msg293099#msg293099 date=1550835242]Parkitt Performance near Newark [/quote] Revs racing, Halesowen Re: Barge like handling - Stinka - 25-02-19 Right, I’m taking it in the get the forks done. I’m 23stone lol, so I’m thinking 10wt oil and 10nm/mm linear springs? Anyone know if that sounds right ? Re: Barge like handling - PieEater - 25-02-19 Sounds good, I'm a similar weight to you and that's what I have in my forks :thumbup I found raising the back end helped a lot with handling, I'd reccomend a 25mm Jack-up kit if you're not too short in the leg department - https://www.ebay.co.uk/itm/K-Yamaha-FZS1000-Fazer-00-05-Jack-Up-Kit-25mm-Dog-Bones-Suspension-Linkages-/223098198451 - I have these fitted along with my Nitron shock at max ride height adjustment. Re: Barge like handling - Stinka - 25-02-19 I’ve taken it to https://www.bikerzracing.co.uk/ Seems to know his stuff, loads of race bikes and stuff in there. He’s going to sort it anyway Re: Barge like handling - Stinka - 28-02-19 Forks done, he’s put 10.5kg liner springs and 10wt oil in Says the compression adjusters were sized and he tried a few ways of getting them free but said they’re fucked What affect will they have on fork action ? Forks were a sloppy spongy mess, I’m expecting a totally different experience now but these adjusters being siezed is a bit pants Re: Barge like handling - Stinka - 28-02-19 (28-02-19, 04:58 PM)Stinka link Wrote: Forks done, he’s put 10.5kg liner springs and 10wt oil in Re: Barge like handling - Old-Git - 01-03-19 10w Oil in the forks and standard is 2.5w (IIRC?) I was going to go with 5w, with the Wilbers springs I've just ordered..... any opinions anyone? |
