J.D. Posted April 1, 2009 Share Posted April 1, 2009 hi. im hoping someone can help me with a little, well a hope little problem i have with my r1 on a 98 year. the rev counter when i start the bike works fine but after about 3 mins it starts doing what it wants, the rev counter flicks up to 4 to 8 rpm then just drops down to zero, it is very anoying but i supose i can deal with it if its going to cost me a fortune, but if there is a fix then i will give it a go, i have a haynes manual for it so will give it a go if any off you can help me.. like i said, the rev counter just seems to have a mind of its own to be honest, flicking up and down from 0 rpm to 8rpm then drops and flies back up again,, also my trip isnt working properly as when i fill the bike up i set the trip, and it works fine until i stop and turn the ignition of , then it re sets itself back to 0 which is again doing my nut it... anyway lads ,, i hope there is someone out there that can help me and believe ,, it will be much appreciated,, kind regards...

steve m Posted April 1, 2009 Share Posted April 1, 2009 First prob!! 8000 rpm is the Fault code for the Exup Valve............ Means ether your Exup valve is stuck and needs a clean and lube or the Exup servo motor is faulty. Second prob !! Check your battery, it may need charging or could be on it`s way out ? then again it could just be a bad connection. Link to comment Share on other sites More sharing options...

J.D. my dads xjr has this prob only his rev counter stopped compleatly at times, his prob was from a bad connection between the gauges and the wiring behind the headlight you could be experiencing the same problems... and if it is that then you should be able to sort it out, but i would also recommend giving the thing a clean its worth a try before doing anything major.

J.D. Hi JD, from other posts it would appear that you have an EXUP problem but as the bike is a 1998 it will be fitted with carbs (with TPS) so the fault code could also be the TPS playing up, the owners manual will give you the fault codes and the duration that the tacho stays at its position, but I would gues if 8k is an exup fault you have an exup fault.

J.D. It's the TPS, i've had the same on my 2000, the part is expansive i think i paid about £70 from yamaha, and it's really, really hard to swap over, it's located on the right top side of the engine right in between the engine and the frame with no space to work at all, you will need a special tool or you will have to make one like I did, there are only two nuts you have to undo but the bottom one is a f.....ing pain, good luck.

JimR Posted April 1, 2009 Share Posted April 1, 2009 That did cross my mind for a minute, well u could do what most R1 owners do buy a new one and end up in an it may work out cheaper than putting a hacksaw to the frame but I guess not ... I'm now to old to run a sports bike, the old man divi thing is fast enuf but I did talk to a younger guy who had a Honda Ciddie Boy Racer (CBR) 1000 today who admited the bike was to quick and on top of that he couldn't handle the hydraulic clutch it was on or off (his idea of running up to 120 in second sounds a bit bizzare to me) but what ever each to there own !

Posted April 1, 2009 Author Share Posted April 1, 2009 cheers for the bits of advise lads, ive tried to get in to the exup valve but on taken the plastics of , the bottom fairing, ive had problems geting in to it as it all is rusty, and the alen keys which i need to take of are rusty which tells me that this is were the fault is, i got to the part were the 2 wires are on a kind of pully system but im thinking the part i need to get at is located behind this,, sort of in the middle of the exhaust, to clean away all the gunk gathered there..then to re grease with copper grease,,,when ive tried to get the 3 alen key bolts / screws of they are having none of it,i did get the pully system bolt of but couldnt get in to the part im thinking i need to get to... wey i sopose ill just have to do with a falty rev counter,, its not making the bike run bad or anything so ill just have to do with that,, ive had a go anyway and i appreciate all your advise lads,, ps .. to all u awlder lads,, super sports is the way forward,, wind it on , and HANG ON..

Regards Jim Fault code for the TPS would be the rev counter showing 3000 rpm for 3 secs,,,,,so if the rev counter is showing 8000 rpm it can`t be the TPS ..

Sounds like You may have been lucky and the valve has seized "open " bout the only thing you can do is keep giving the bolts a squrit with penatrating oil and hope they free up. You could also try disconnecting the cables at the exup valve, leave then in position but disconect from the pulley,this should stop the rev counter displaying the fault code.

J.D. Hi JD, Not sure if you have fixed your problem yet but a 8000rpm fault display on the tach is for the Fuel Level Indicator Light not the EXUP. The fault display for the EXUP is 7000rpm. Check your connections to the fuel tank. Jase Link to comment Share on other sites More sharing options...

Jase didn't mean to do a reply ... but do agree with JABBOTT .. typically the fault is a wire coming loose on the sender inside the tank. Link to comment Share on other sites More sharing options...
Bob R1 Posted September 17, 2009 Share Posted September 17, 2009 I had exup trouble on a 98 R1,the bike rode fine until i hit fairly high speed when the needle would stick at 7000,when speed was dropped the revcounter would be normal again,because of the position the valve is in its always rusty,.if you dont want to spend any money,just release the exup cables from the pulley or from the motor ,its under the carb bank,revcounter will behave normally again, but the valve will be stuck closed probably,with less power maybe fit a full system,.
