MAp ideas ? +exhaust/performance questions.
 
Alright guys,

After a map for the following, plus a little question.

2010 XTX, Kev O2 fitted, K&N 1&2, Leo Vince exhausts. AIS Blocked.

So, first,
What do you rekon the best map is ?

Currently the cans have pretty large baffles in them, see pic below, the long ones. How much would this be holding it back compared to none/small ones fitted ? You can't really see the smaller ones, they're in the left of the bag and are about 3" length... stnadard is a good 10" maybe more.

Thanks in advance.

Question time while i'm watching MotoGP.
I noticed earlier this week when i rode the bike with the new LeoVince cans that at 30-33mph it's a little... well.. not quite right. You can feel what's a common issue these days on bike of poor fueling. IT's only minor, but it's there a smidgen. I didn't have this at all when i had the other exhausts fitted.
What's the difference you ask ? Well the LeoVince have/had a MASSIVE baffle in there. It's about 20mm diameter and approx 20cm long. Inside the exhuast you seem to have 3 cylinders at the top, although 2 of them become completely redundant as they are above the height the baffle goes, therefor all the expelled air can only go through the 1 cylinder, not using the other 2 at all. THe cans come with multiple baffles, i've fitted the smaller ones for the day, they allow air through all the cylinders inside the exhaust. However at the expense of MASSIVE noise... With the other can previously fitted the bike was proper loud, silly loud... However, it's proper loud like a (pseudo)Supermoto should actually be of course :) but... i leave for work at 6.30am and i'm going to be deeply unpopular with the neighbours if i leave them out. With them in, they sound good enough to be 'fruity' without being silly.
So i guess the question is, regarding performance. Considering the bike makes say 50bhp as it is and is mapped accordingly... What sort of bhp/performance loss are we looking at from leaving the baffles in ?
There's of course the argument that,
1. It doesn't matter what the performance loss is... Of course i 100% agree with that
2. It's a Supermoto, it's supposed to be horrifically loud
But... that doesn't mean i wouldn't like the answer.

I know mate, it's bookmarked on my favourites... However, i'm not really asking for a list... that only tells half the story, ... I was after more real world expeirences of similar setups

Don't take that like i'm being dismissive, i'm honestly not... But you know, they're quite specific in their description and none really fit with my actual setup of cans, o2, baffles, snorkel, AIS blocked and Stage 1&2... so i was more after an idea, rather than the list.

1. Yes the bike feels smoother
2. Actually it feels quicker LOL.
3. It's LOUD... loud beyond words.. loud beyond the realms of belief !...

The baffles have been put back in it.
