slack Posted January 1, 2012 Report Share Posted January 1, 2012 Hi Guys & a happy new year to you all,Here goes i am posting this topic for my friend again as he is still having the same problems.The bike runs for approx 30mins then shuts its self down to tick over & half throttle.He has just had the bike to a well known bike mechanic & friend & had the following done. A new injector,fuel pump stripped & cleaned,tappets reset & plugged into computer to find the fault.But still has an issue.He's checked his manuel & it is saying check the TP VALVE but he does not know where to find it on the bike. Any one with any ideas it would be appreaciated. THANKS. Quote Link to comment Share on other sites More sharing options...

Hi It could mean throttle position sensor ? http://www.trialaction.dk/Portals/0/downloads/COTA_4RT_manual.pdf Not sure if that helps Cheers Michael Quote Link to comment Share on other sites More sharing options...
nigel dabster Posted January 2, 2012 Report Share Posted January 2, 2012 is it the tilt sensor? Is it always at 30 minutes? take the bike to AG BIKES in richmond they are good. Quote Link to comment Share on other sites More sharing options...
honda_freak Posted January 2, 2012 Report Share Posted January 2, 2012 Throttle sensor is built into the bike's ECU and is therefore not available for any measurement of this. If you want to measure the TPS, you must remove the ecu from the throttle body and even then it is not advisable to separate the ECU, because tps sensor located on ECU's mother board. If you are sure that it is the tps sensor is faulty - it is my opinion the only way to solve your problem, is to initially borrow a known good ecu (throttlebody and ecu) from a friend. The outcome of this will determine future steps to be taken. Regards Honda Freak Quote Link to comment Share on other sites More sharing options...
turbo Posted January 2, 2012 Report Share Posted January 2, 2012 cant help much other than when i had problems with mine recently, spoke to Pidcocks who were helpfull but basically said that they fault find by swapping parts one by one , which is what I did , borrowing a mates bike to find out my throttle body had clapped.These 4rts are not the easiest bikes to find faults on.

jimmyl Posted January 2, 2012 Report Share Posted January 2, 2012 Still sounds like fuel pump. Only plays up when hot. - about 30mins. Will then just not rev out at higher rpm. Bit like a dirty carb/blocked main jet. Park bike up and let cool and is fine again until warms up. Will keep running but poor at top end. I am not aware of anybody being able to clean/repair the pumps. You can clean filter etc but made no difference to mine. See if you can swap a tank assembly with somebody - only a 5 min swap. Would try this first then a maybe swap throttle bodies. Second hand Non PTB are quiet common and cheaper than a fuel pump. If anybody has had any joy getting fuel pumps repaired would be intetsted as got my faulty one still lying under the bench. Only aware of early 05/06 bikes having pump problems unless anybody knows different. Best of luck Quote Link to comment Share on other sites More sharing options...

Best of luck If water and engine temp is getting to high ecu will reset to low safty revs perhaps this is your problem. Cheapest is to start switching temp. sensor in the lower of radiator Quote Link to comment Share on other sites More sharing options...
nelly1 Posted January 2, 2012 Report Share Posted January 2, 2012 do they have a crank possition sensor if it was a car i would deffinately say it was that Quote Link to comment Share on other sites More sharing options...
slack Posted January 2, 2012 Author Report Share Posted January 2, 2012 Thanks to everyone for your reply's i will pass on all the comments made.I suggested swapping parts but not many people riding them in our club now & we(his mates ride GG)so he'll have to do a bit grovling to some one at the trial. And once again many thanks. Quote Link to comment Share on other sites More sharing options...
