fitz_the_viking Posted August 16, 2015 Report Share Posted August 16, 2015 Hi Been having some issues with the mixture on mine, plug is always sooty black, went through new plug in a trials and a practice today, saw that the TPS was loose too, anyone know of somone in the leicester area that can reset the tps and have a fiddle with the mixture? i have had a google but couldnt see any trials mechanics in leicester at all but them i am not the best at googling. I do plod around on the easy routes so i dont make the bike work as hard as it could, i cleared it out with a quick 4th gear full throttle blast and it smoked like hell for a while. that did make it a little happier but then wouldnt idle, cleaned the plug and its all lovely again. makes me think the exhaust could do with a re pack too, any ideas on how to do this without cutting a hole in there? am using the higher RON petrol (not race gas) with 50mls of silkolene race oil per 5l. cheers all Quote Link to comment Share on other sites More sharing options...
barryb1973 Posted August 19, 2015 Report Share Posted August 19, 2015 cant do exhaust without cutting,try dropping to 40ml that should help thats what i put in mine also give it a good rev to clear it out make sure air filters clean Quote Link to comment Share on other sites More sharing options...
twinshock giles Posted August 24, 2015 Report Share Posted August 24, 2015 Isn't the new Ossa recommended to run at 120:1? That sounds a frighteningly little amount of oil but if thats what it takes not to upset the system. That may account for the fouled plug?

fitz_the_viking Posted November 8, 2015 Author Report Share Posted November 8, 2015 sorry forgot i posted this. i have had the tps reset and a couple of codes that came up cos i had run it with the tps on the cock. the plug is still sooty black, i am going to try putoline 45mls per 5l. your right it doesnt sound alot but thats what the book says. ill see what happens. the exhaust i believe to be clogged too, its had 130 hours on it, seems a right faff to repack it and a replacement aint cheap and the termi is over 800 quid. mmmmmmmm decisions decisions. a good clearout run aint doing the job.

telecat Posted November 17, 2015 Report Share Posted November 17, 2015 We run 50ml Synthetic Oil to 5 litres of Tesco momentum. I also put in 50ml of Silkolene FST Pro boost. It's a liitle smokey when cold but runs fine when warm. I also fit Iridium plugs. Chris's is a 2014 300 for reference. I can recommend Andy at Pennine Trialsport if you need any specialist advice but he is a bit away from you. Quote Link to comment Share on other sites More sharing options...
imexian Posted November 23, 2015 Report Share Posted November 23, 2015 Hi, What's the best packing material for the tremignoni exhaust? Loose or wadding, seems like there is some wire wool in there as well!! Quote Link to comment Share on other sites More sharing options...
fitz_the_viking Posted December 4, 2015 Author Report Share Posted December 4, 2015 (edited) changed to mx9, using bp ultimate fuel. killed the first plug today. the annoying thing is that on any other bike its a quarter of a turn on the air screw. also unless its wide open it doesnt like 3/4 to full throttle, it seems to bog down, but it runs a million times better and starts easily after the tps got reset. will have to go and see the bloke at cambs trial center again. he is the closest to me. the fuel treatment sounds like a good idea, i ran that in my bandit to stop the carbs from freezing, so does the iridium plug. will give it 40mls of oil next time too.

lotus54 Posted December 12, 2015 Report Share Posted December 12, 2015 I 'flashed' the newer firmware on my 2014- it runs better and starts even easier. I did mess about a little with baseline mixture - I run 100:1 Motorex full synth. Non- ethanol fuel (makes a difference, but probably not an issue there?) I run a hotter plug then recommended, I've never seem any sign of it being too hot. I found the bike is a bit touchy for likeing a clean sparking plug. I run a spark arrestor and need to make sure it stays clean or it runs like crap. I have something like 250 hours - still runs great. It seems to like a TPS reset every 100 hours or so. If I notice a bit rich, I just reset and everything is fine. Quote Link to comment Share on other sites More sharing options...
jsp Posted December 13, 2015 Report Share Posted December 13, 2015 once you've bought the cables where do you get the software from ? Quote Link to comment Share on other sites More sharing options...
canada280i Posted December 13, 2015 Report Share Posted December 13, 2015 Software is supposed to come with the cables along with a bunch of maps Quote Link to comment Share on other sites More sharing options...
lotus54 Posted December 13, 2015 Report Share Posted December 13, 2015 Yes, it comes with software/maps/manuals. I can send those to you if you like. Quote Link to comment Share on other sites More sharing options...
fitz_the_viking Posted December 16, 2015 Author Report Share Posted December 16, 2015 (edited) that might be worth a go too. i am doing a training session this saturday, first time out with 40mls of oil and the fuel treatment. i have a hotter plug and have thought about it but i have blown holes in pistons before and had the ballache of repairing it so its good to hear someone else has done it i have heard the more modern maps runa little leaner. when i was cleaning the bike a thought came to me. there was the ecu, a relay and the battery to the easy start in the airbox. i could hardly see the filter, the bike starts fine so i have removed the battery and am hoping it will allow a little more air to flow freely in the airbox. aything is worth a shot. the tps was reset less than 10 hours ago. cheers for all the suggestions everyone. also going to change from esso high octane to bp.

fitz_the_viking Posted December 19, 2015 Author Report Share Posted December 19, 2015 we have a result!!! no the one i was hoping for but hey. instead of burning through a plug in 4 trials i managed it in a record 2.5 hours. didnt rev out properly, ran really rough. surely less oil means a richer mixture, if i am right the oil doesnt combust jut lubricates right? so 50 mls of oil will mean less petrol in the chamber.

cornishtwinspring Posted December 19, 2015 Report Share Posted December 19, 2015 Richer or leaner mixture is air/fuel ratio.The oil in premix is to lube the big end/mains. That said to much oil will naff up the clean running by oiling up the plug until it stops. 1 Quote Link to comment Share on other sites More sharing options...
