youshouldatappdR1 Posted January 23, 2014 Report Share Posted January 23, 2014 Firstly, I'm after the name or even the supplier of (please excuse my scrappy description) the chain holder you would see on endurance racing bikes. It sits on the upper rear section of the swing arm, bolts to it and has multiple jagged teeth that sit in between the chain links to hold it whilst the mechanic or pit crew is changing tyres, sprocket, etc. I've searched for this under multiple names, with no result. My other question relates to the cooling system. From what I've read most bikes come with a ntc thermistor for a temperature sensor. I'm curious as to why they would use this as opposed to a thermocouple? aging of the thermo? temperature constraints? voltage to small or irregularities? Apologies in advance for the fiddly questions (and the many more to most probably follow). Link to comment Share on other sites More sharing options...
smobytoe Posted January 23, 2014 Report Share Posted January 23, 2014 Cibbers on here has one but I am really not sure where it was sourced. He may well be along shortly. Hth Link to comment Share on other sites More sharing options...
blow_away Posted January 23, 2014 Report Share Posted January 23, 2014 http://pbmagforum.co.uk/index.php?/topic/29536-project-cbr/ The chain doodah is in this thread somewhere, if you don't want to read all 32 pages you could PM Cibbersicks Link to comment Share on other sites More sharing options...
youshouldatappdR1 Posted January 23, 2014 Author Report Share Posted January 23, 2014 i've been rrading through it since smobytoe mentioned it. firstly, cibbers, fwark! thats a nice cbr. i then followed the link, and had to have a moment alone when i saw the bikes on the tsr site. wow. http://shop.tsrjp.com/item/IS00008N00077.html?PSID=df56f6758521f0eebf7e8d5d073950c2 Link to comment Share on other sites More sharing options...
DougW Posted January 28, 2014 Report Share Posted January 28, 2014 NTC ( Negative Temperature Coefficient ) thermistor is an easier/cheaper way of measuring temperature, thermocouple may be cheap but requires a more sophisticated amplifier with cold junction compensation to measure temperature. Measuring the change in resistance of the thermistor is easier. With recent advances in chip manufacturing this answer may well now be B******s, its 23 years since I was an Instrument/electronics technician.
