You are going to get good advice and suggestions from Luke. In the end I think it was a combination of things for my bike that I think caused the weave. I tightened head race, replaced swing arm bearings and spent a lot of time on the suspension. My r6 Shock had been reworked by reactive suspension prior to me getting hold of it and as such had a slight difference in settings. This resulted in suggested settings being slightly out in so much that even a quarter turn rather than a half turn could make all the difference. What I am saying is grab a pen and paper, put the shock to Luke's suggested settings, stick the tools in your pocket and then find a piece of road which has bumps and turns in it, make minor adjustments and record them until it feels right for you. Do rear and then work on the front until the two work together. Once the two married up the weave pretty much went. It really is a slow methodical approach to get it right. The settings you had with the r6 shock and standard front are not likely to be what you need now with the new front springs so you may need to play a little bit for them to come together again. I have just come back from 1400 miles trip around Scotland and the bike was embarrassing sports bikes. I also fitted Dunlop Roadsmart 3 tyres which were brilliant in both wet and dry conditions and have really deep tread, they hardly look worn showing the suspension is working well. Luke made a comment and I think it sums up the bike well...'You can sort the suspension but you will get flex in the steel frame' I agree. The bike handles very well now but it will never be sports bike stiff and if you have come from Sportsbikes like I have the flex when pushed hard is noticeable. However be smooth and take note of the bikes limitations and it will hustle along at a mighty pace. Good luck and you will get there in the end.

I have gone through all the bearings again. I think the swing arm bearings have some side to side play. It wasn't noticeable before but after spending half the day trying to identify the problem with some high speed runs I am convinced it has play in it.

I got the shock elsewhere, the dog bones and the set up from you. The shock has been refreshed by reactive suspension and was working sweetly prior to the front getting ktec springs and oil. It's the right shock, I checked with you via email prior to fitting. The only reason I have raised the preload was to try another option while attempting to sort out this speed weave.

So today I put the front forks back to recommended settings as per the fazer manual despite the ktec springs and thicker oil. I also put forks back to flush with yolks. I did as you suggested with the loosening of bolts, bouncing front and tightening. It made no difference. Hard acceleration around 110mph (closed road!) speed weave. Forks thru 10mm...standard settings...same. Forks thru 13mm! Same! Rear preload up to one off max. Same! Front rebound dialled back to absolute minimum and all as before...the bike is on its nose. Same though maybe not quite as violent. Really stumped! I am thinking of taking the forks back to the mechanic who fitted the springs and oil...summats up!

Hi guys,
I intend to try the fork bolts tomorrow. Tyre pressure wise 42 rear is recommended for rider and passenger while 39 was for solo....it is in my Yamaha service manual anyway. The front pressure is my preference but again manual states 36. I was running these pressures before in metzlers and also Dunlop qualifiers with no issues although I fully accept the tyres are different now as is the suspension. Headstock and all other usual suspect bearings are fine. It's the standard r6 shock conversion in which case the rear Spring should be stiffer than the standard one. Dog ones were done as per Devilsyam's genius. I have one up on the high speed damping but no difference as yet. I will as I say try the bolts and all standard set up again tomorrow and see how we go. Thanks for the suggestions everyone.

A few good ideas there guys. Once it stops pissing it down I will give it a try

Linear springs, rear ride height preload at third from highest, sag correct for my weight, tyre pressures front 35 and rear 39...and no problems at these pressures prior to forks being done. Can't say exact weight biase but with forks dropped 10mm and preload up at rear roughly front 52 and rear 48.

Thanks for the suggestions guys

Hi all,
Yep it's another tyre thread! Sorry but I am considering a pair from the current crop of tyres which offer the all round performance and good mileage. Having not used any of them cos I usually buy the best priced half decent tyre on offer from eBay  , has anyone used any of them and can recommend on the gen 1? I would say my general use is hooning, odd commute, a couple of long tours a year. Riding style smooth and rapid.   I have ktec springs up front, forks 12mm raised, and the r6 Shock conversion plus the usual ivans modifications. Cheers.

If they give It a fazer style top fairing and a decent sized tank I would consider it. Standard tank is only 17ltr and we all know how backward a step that was on gen 1 to gen 2. I also have a big bang r1 and its a thirsty beast!

It's fixed!!!!
Ok...so interesting problems were finally identified.
Fuelling...unbelievably one of the tiny springs which tension the carb needle to the plastic housing needle cap inside the diaphragm had failed. It was snapped in two but remained on the top of the needle (luckily!) but there was no longer correct tension on the needle. This in effect allowed the needle to vibrate and jump about leading to the stutter. If you were smooth on the throttle it hardly registered but grab a handful and it reared it's head. Who would of thought it?
Electrical fault...Right hand coil. Where the two wires which attach to the coil with push clips. The wires feed back into the loom and are covered with a protective plastic cover. Once I cut the cover away approx. 2 inches along the loom I found one of the coil wires had corroded. I know it was still protected by plastic but somehow this was intermittently shorting.
It's been a journey and a half with this one and I guess it's unusual for either of these faults to occur on a Fazer ( my middle names Lucky!) but hopefully if anyone comes across a Fazer with similar problems then don't discount what I found on mine. Normal service has now resumed baiting the young guns on sports bikes and to say I am now a happie chappie is an understatement. Thanks to everyone who contributed and showed an interest in my thread. Keep it sunny side all! Cheers!

Still got issues....still trying to find the problem.....still pulling my hair out!
