The Bar

hi guys I have a 2000 thunderace and when I took it out of the shed the other morning it seemed to have developed a misfire . very lumpy at low revs and not wanting to pick up unless given a handful and stinking of petrol I have replaced the standard exhaust with a stubby race can and thought this could have caused the problem but after replacing the standard exhaust yhe misfire continues could it be as simple as a plug off or something more serious

As y'all know, I have a 1998 Thunderace... It's THIS colour: Vivid Red Cocktail But..! There's ANOTHER one!!! VERY close to where I live, I see it sometimes on the way to work! It's even the same colour pattern!!! I don't know who he is or where he lives or how long he's had it, but it's really, REALLY strange seeing 'my' bike on the road! lol There's so few of them left, and this is the only other one I've seen in 'my' colours. I'm getting mine back on the road for the start of the season after riding my V-Strom for the last year. I'll surprise him one morning and drop into convoy..!

Iv got a thundercat on 98 plate does anybody know if possible I could change the rear with a r6 end thanks phil

Hi, new member. Does anybody have a good diagram or photo of front fork internals, as there assembled. Changing my seals and it looks like the small rebound spring isn't in the right place. sort of jammed looking on the large c clip in bottom of stantion. Looked on the net at manual pictures and very vage looking, were it goes. and looking at it, it doesn't look comfortable anywere. any help appreciated. cheers.

Hi so I've just bought a 1998 Yzf thundercat she's a project it's fair to be said. I've bought 2 paddock stands to do all the maintenance myself (or try) and the rear has bobbin adaptors. Anyone know where these fit on the thundercat as in struggling to find any specific for the cat? Thanks

Hi. I am new on here despite owning my Thundercat since I was 19yrs old. I have not had it on the road for two yrs since I bought a new Honda 600rr and now want it back on the road! It failed an MOT last yr on rusted downpipes and have just taken them off etc and am looking for replacement ones. Does anyone have anything to offer on replacement ones in terms off what to get. I know some people say aftermarket ones don't always fit easily!!!! I would buy replacement non stainless if necessary. I would be doing arounf 500 miles per year at best!! I look forward to hearing what people think. Thanks Rob

hi all i have had my 1996 thundercat for just under 2 years now and for the past 4 months in my spare time i have been taking the engine apart and rebuilding it due to killing the gearbox...... after encountering a few other problems which have been overcome and managed i am now in the final stages of rebuild and the crank seems to be binding when its all built up. I am completely baffled i have taken apart and reassembled the top part of the engine multiple times to no avail. All i can say that the noise it makes when turned over is a grinding, rubbing sound and its coming from piston 3 area.... i think. Help......

hi im new to this forum but wondered if anyone had any idea what the normal engine temperature should be on a yzf 600 thundercat 1998. the only reason i ask is that last week i took mine up to scotland and have never used it in the cold before but normally the gauge reads about 60 degrees c but when i went up north it dropped to about 40 degrees c and started missfiring. all the lads at work say there bikes are normally running about 75- 80 degrees c and dont fall much below this when on the move. when the temp on my bike drops it starts to missfire but when i stop and the temperature rises it stops missfiring. my suspisions lie with the thermostat or lack of t…

HI I HAVE A UK SPEC 1997 THUNDERCAT WHOOSE FRONT BRAKE CALLIPERS HAVE SEIZED. I'VE BEEN TOLD THIS IS A COMMON PROBLEM WITH THESE CALLIPERS AND THEY WILL NEED REPLACING, AND HAVE BEEN RECOMMENDED FAZER CALLIPERS AS A BETTER ALTERNATIVE. CAN ANYONE CONFIRM IF FAZER FRONT CALLIPERS WILL FIT MY CAT AND IF SO ANY PARTICULAR MODEL/YEAR OF FAZER? OR DOES ANYONE KNOW ANY OTHER WAY TO CONFIRM THIS BEFORE I SPEND MY HARD EARNED £'S ALL ADVICE AND SUGGESTIONS VERY WELCOME. THANKS

Hi guys i've had my thundercat for about 3months topped up the anti freeze a month ago and now everytime i take her for a ride the antifreeze comes out of the overflow pipe.What worries me is that the antifreeze container never seems to get empty but the water keeps flowing? shouldnt it stop overflowing when it gets to a certain point? Just want to make sure it's nothing bad. thanks

Got my new bike the other day and it all good apart form when am doing slow speeds <30mph. it seems to not like slow speeds at all. Sounds chuggy and makes strange noise in all gears when slow. Anyone know what the problem is? Thanks kev.

Hey folks. Quicky question to pester you all with. I bought my Yam Thundercat 600 about 6 months ago and have noticed there is very little feel from the rear brake? A quick inspection shows the pads seem in good nick and not being mechanically minded I'm not sure where to look next. Any advice would be greatly appreciated. Thanks, Andy

Hi guys, I am in need of some 33bhp washers for my 1997 thundercat. Does anyone know where I can get some secondhand, I dont really want to spend £270 on small washers which im going to take out in a year or so. On a similar note is there anyone on the forum using an throttle stop as a restrictor ?

Just fitted a 33bhp restrictor kit myself that I got of someone who used to have their cat restricted The washers went into the inlet manifolds like they are meant to Went out a ride and in first gear it revved up to 12k. Is this normal? I know the washers are in there and they are for the thundercat I dont see how they could have came out though :S any ideas?? Cheers

When running at idle and low rpm in traffic or pulling away, my thundercat runs rough, splutters and has little power. It happens when the throttle is just cracked open. Once through this and opened up its fine. I believe it started when i left it standing over winter ( I put it down to petrol gone off) I have cleaned out carbs, checked sync, changed plugs and checked for air leaks, all to no avail. Has anyone had similar problems? Is there anything else I could try?? Thanks - rosie

Hi there, I have a Thundercat which is running hot when stationary (i.e. in traffic). The fan doesn't kick in until well into the red which I understand is common but it has actually boiled over before now. I am going to change the thermo switch for a lower operating spec switch so just canvassing opinion on what would be the optimum temperature for the engine to run at please? Any information greatly appreciated, Cheers, Lee
