Would any full exhaust map work for the GPR exhaust that I have on my bike?? I installed the pc3 today and put the arata full exhaust w/ stock filter map on my bike. Would that be ok to run at WOT? When I rev is up a little some smoke comes out....is that normal? Just wondering if that tune is safe for me to run at the moment!

Thanks in advance

Any map close to your configuration will be as good as the next. Who knows how it will fit your bikes fuel mapping so try several until you find one the bike likes. It doesn't have to say "GPR" or "Arata" on the map to fit your bike. That will tie you over until you can get it on the dyno.

Hey cbr600rr04,sorry for not replying to you PM earlyer.
But hey on the "arata map" .well i was going through the samething as you,i had a brand new full GPR but no map. so the first thing i remember was that powercommander had some maps .i went ahead and tryed out the arata map and since then iv been happy .i havent had notice any problems besides running a lil bit rich (i could smell it). OH and also notice that it does pull a lil bit harder on high gears.
ill be mapping my bike pretty soon,im just waiting for my "stacks" which have been on backorder for almost a month from "ronayers.com"

hey what color is the smoke? im hoping its black(not good if another color(unless its really cold out)).

black- engine is running rich
blue/grey- oil being burnt somewhere
white- coolant being burnt somewhere


if you bought the exhaust brand new then its possible that there is still some oil on the inside of the pipes that comes from the manufacturing process. some companies remove it while others put more on(anti rust). usually on a new exhaust it will burn blue for a little while then stop after a good ride. its also possible that the smoke you see is from the muffler part. some manufacturers put their muffler pack(fiberglass usually) inside a burnable plastic bag, this gives it longer storage time/shelf life and keeps the packing material from absorbing lots of moisture during wharehousing/shipping. this will also burn out during the first good "hot" ride.

if the smoke is black your just running rich somewhere. if its black at idle then its just dumping a little too much at start. if its excessive it could lead to hard cold starts, and worst case it could cause cylinder wash leading to hot starts(no oil). very unlikely as an excessive amount of gas is required to reach this point.

so what color is the smoke and when does it occur? high rpm? idle? midrange? WOT? etc etc. Brand new exhaust?

is it better to run rich than to run lean?

 

[NewRedRider]

Safer to run too rich. Too lean will burn a hole in the piston or the valves.

well as always there is a compromise. a leaner burning engine will run hotter, and combustion temperatures are also greatly increased. end result if too lean you get detonation and if bad enough bye bye pistons and more.

if it too rich the engine will run like crap, could be hard to start when cold outside. if excessively rich then the gas will wash the oil off the cylinder walls. this causes lack of lubrication, and if bad enough could seize the piston and cyl together. or just accelerate wear on rings and walls. also if its bad enough its possible to get a buildup of fuel in your crankcase which does as mentioned above to other parts. it could also be a small bomb(just thought of a funny/scary story).

anyways its much more likely to cause damage with the first scenerio, its about 10 times more likely. to get the engine to run rich enough to cause the problems in the second scenerio, you would have to be really stupid, and you should be banned from touching a bike ever again. lol.

it is possible, however, that an injector could get stuck open and flood the engine this way. if you see this happen immideatly shut off the engine and fix the problem. open the oil resivior and smell for gas. if you smell gas you need to flush the oil, filter too. when you go to start it after the flush, disconnect the fuel so the engine will not start and crank it a little to get some fresh oil on the cylinder walls to avoid a hot start.



damn sorry for writing so much... i get carried away

ps im waiting on some new stacks from that site as well lol. not in a big hurry yet though.

Yeah so I havent noticed any more smoke so I guess it is running ok....Def can feel the pull sooner and throttle is 100times smoother. Prob going to get it mapped pretty soon.... Thanks
