imexian Posted June 2, 2015 Report Share Posted June 2, 2015 Hi, which is the most recommended plug for 280, bp5es in at mo. Any ones which make it better? And start a bit easier.... Quote Link to comment Share on other sites More sharing options...
dadof2 Posted June 2, 2015 Report Share Posted June 2, 2015 (edited) BP5ES is the most common plug for liquid trials bikes ridden normally (not hard) An iridium plug (more expensive) will in theory make it start easier and run better but you probably will not notice the difference. A correctly set up bike should work fine on a BP5ES Edited June 2, 2015 by dadof2 Quote Link to comment Share on other sites More sharing options...
canada280i Posted June 3, 2015 Report Share Posted June 3, 2015 I have run an iridium plug in both my 2011 and factory r and it does start easier I think. Do you have the 9v easy start installed? If so also use a lithium battery as that also helps Quote Link to comment Share on other sites More sharing options...
imexian Posted June 3, 2015 Author Report Share Posted June 3, 2015 Ok just ordered a lithium battery for the 9v easy start, got iridium plug coming as well.... I know you have had a Ossa for a while (Canada280) do you have any tips on starting technique ? i've had loads of different advice but still not great on firing up!! Been out Sat/Sun and last night, bike is mega, prob best trials bike i have ever ridden, but the starting is a bit of an achilles heel....!!

canada280i Posted June 3, 2015 Report Share Posted June 3, 2015 I know people who have no problem starting at all, unfortunately as I have admitted in the past, my technique is crap so I still have issues, especially when I am tired! My best advice is ti always try to start it when standing on the pegs leaning against a tree or something. I then get the starter to the top of the stroke and give a good firm kick through. With the latest mapping my bike is 2-3 kicks from cold using this method and first kick when warm. I have seen people "snatch at the starter which also seems to work, just not for me. Is your mapping up to date? Quote Link to comment Share on other sites More sharing options...
imexian Posted June 3, 2015 Author Report Share Posted June 3, 2015 Its well strange!!! kicking it up with all sorts of different ways, sometimes its so dead it seems like it will never go again...!!! then suddenly sparks into life like a rocket!!! no rhyme or reason ?? ive had it fire 1st kick, (once) 3rd 4th 12th 30th etc...LOL When warm/hot makes it no better, in fact prob worse. Does the fuel pump need to make a noise with the easy start depressed? Can i use a bigger voltage battery? how about a truck one....!!! LOL...

canada280i Posted June 3, 2015 Report Share Posted June 3, 2015 you will find with the lithium high power battery that the fuel pump makes the noise as it primes. Is you mapping up to date as the new maps kept getting better. what year is your bike? Quote Link to comment Share on other sites More sharing options...
imexian Posted June 6, 2015 Author Report Share Posted June 6, 2015 Hi 280, lithium bat, irid plug **** crap... Does not make priming noise with easy start and better bat!! Don't know what map? It's a 2013 Ian N Quote Link to comment Share on other sites More sharing options...
imexian Posted June 6, 2015 Author Report Share Posted June 6, 2015 I've had to bump start it twice today, and so many kicks I carn't count that high...... Quote Link to comment Share on other sites More sharing options...
ric h Posted June 6, 2015 Report Share Posted June 6, 2015 When was the TPS and idle set last? They are very important to a modern Ossa.y 280 was horrible tilll they were set,and now it's always 1 kick when warm and 3 or 4 when cold.

canada280i Posted June 6, 2015 Report Share Posted June 6, 2015 Just to clarify, when you are kicking it over you are holding down the easy start button right? Not just pressing it and letting go before you kick it. You have to keep it pressed to charge the system, then when you move the kickstart into position you should hear it prime the pump, maybe not the spfirst kick but certainly on subsequent kicks, every time, especially if using a high power lithium battery. If still having issues I would definitely get it checked for TPS and idle which should be 5 degrees and approx 1400rpm or a little lower if you prefer Quote Link to comment Share on other sites More sharing options...
imexian Posted June 7, 2015 Author Report Share Posted June 7, 2015 Thanks 280, I've had a lot of conflicting advise about the starting, 9v system etc, one dealer said hold for 3/4 seconds then 2 kicks to prime them a good one to start...I've held button down all time as well, no difference, never ever hear fuel pump priming with switch, or anything, when first got it a did once then never heard again, it did come with a shrink packed Aa type pack, but as it never worked again I thought they maybe faulty, so swapped to square 9v battery. Dealer wired in after consulting with Nigel Burkett, so must be wired ok? Ian Quote Link to comment Share on other sites More sharing options...
canada280i Posted June 7, 2015 Report Share Posted June 7, 2015 3/4second is the new easy start, 2014 onwards. 2013 and earlier use the 9v system which is basically the same principle, purpose being to per gargle the electrical system for easier starting. As per my post in the other string, check for spark by removing the plug as you have changed the plug cap Quote Link to comment Share on other sites More sharing options...
imexian Posted June 8, 2015 Author Report Share Posted June 8, 2015 Posted this on suppressor cap posting, just so everyone knows..... STOP PRESS!! wires crossed on kill button/9v battery to capacitor, swapped around, the beast works!!! 2 kicks to prime good kick off she goes!!! at last a result!! im off riding......
