As some of you know I've never been properly happy with the throttle on my 2010 RRA Blade... Essentially it is going from open throttle to closed throttle at small throttle inputs in the typical range of 0-5 % throttle which makes the bike an utter PITA when filtering through traffic. I'm 99% certain that it can be mapped out ... and have so far installed (on a stock bike with exhaust valve disconnected) a Power Commander PCV with Dynojet O2 eliminator and the recommended map as shown here (lower rpm only as this is the area I'm discussing): It's a lot better with this setup... but I want to smooth out the roll on - roll off transition to make it a bit easier through traffic... i.e 0-5% range... circa 2000-4000rpm I've got three weeks till it goes to a mapping specialist but wondered if anyone on here has an experience of modifying the lower throttle figures to smooth out throttle transitions or even has a difference map for me to try - even better custom map for a stock bike! I'm thinking enrichen of the fueling at lower throttle openings would smooth things? Any suggestions?
without sounding patronising,i assume you checked the chain to make sure it's not too slack,and also the amount of play in the rear sprocket carrier.?
I'm open to all suggestions mate... Bike is in A1 condition with correctly adjusted / lubed chain and throttle.. the bike has only done 4,000 miles from new.
Whilst the chain and carrier suggestion is bang on, it really does seem to fit with a lot of owners experiences, mine was identical even with a new chain setup. the issue was only cured from 2012 on, the 14 model is even better, totally glitch free.
Hence the mapping I am having done I hope will cure it / improve it ... Anyone done this on a stock bike?
Ocd did you change the air filter or is it the one that was in the bike,this will make a massive differsnce in the outcome
Air filter is standard... I've only owned the bike two months so not really touched it. (Other than install PCV)
I would put a new air filter in whether a standard or a k and n ,u will see it will make a massive differsnce,u would not run a marathon with a mask on would ya ,deffo change it ,it's likely to be the cause
Standard filters are supposed to be great as is Graham. When i changed mine...had no difference. A map sorted it out good style.
Have you considered an Auto Tune? They provide the ideal fuel / air ratio in real time. I had the same problem on my 2011 blade a session on a dyno has improved it but not completely. I had a ride on a 2012 blade a few months back and I couldn't believe how much better it was stock. I'm now considering an auto tune.
standard filters these days are as good any aftermarket filter (or at least not that you would notice).good thing about aftermarket is they can be cleaned rather than replaced.
They require quite a bit of fettling to get them work so I'm led to believe and is yet another box to install on the bike so isn't really the route I want to go... I have uploaded the map Simon sent me to the PCV and hopefully will be able to try it tomorrow (ice up here this morning so car today) ... will give me a good comparison between Dynojets base map they provided. However, the bike is booked in with these guys FW Developments | Services | Fuel Mapping in two weeks... and I'm pretty sure they will sort it hence don't want to fiddle too much...
The auto tune isn't another box it replaces the existing lamba sensor and plugs into the PCV. That said I think a session on the dyno should improve matters so see how it goes.
Your right sorry about that I always thought it plugged straight into the PCV. Still it's a very small black box.
