TC, Paul and rest of the crew,
thanks to you and all the rest who have contributed to making life to other Max owners
a little bit more comfortable and understanding. My boss and friend owns a Honda CBR
600 and he is very surprised on how tight a relationship can be between fellow Maxers,
I think he is a bit jealous, but I don't tell him so.
I'm not a crab and don't like to crawl backwards unless there is no other way and I'm
determined to make this thing work. I have been tempted to retrieve and go back to
what I had, but the TBR are such a nice set of canisters and make the bike look so
much better, that I can't even image me doing so. Dynojet clearly specifies that they
require fully open mufflers or cans to get the best from their kit and I followed
their philosophy to the bitter end. Now I find that the Stage 7 Kit could perform in
a more than desirable way with the standard box and a less than acceptable exhaust
system.
I never managed to get so much power out of my Max in such irregular conditions, so to
me this change to the Two Bros Racing canisters was a clear step forward and that
would even increase the performance on my bike by a long shot. Dynojet suggest using
as they say, quote:"1. To obtain the most from this jet kit you must use a medium or
competition baffle or have drilled out the stock baffle". I think that in this case
TBR cans are more than enough.
To Paul's mail I have to add that I never changed two items at the same time, since in
my case I started off by replacing the cans from Laser to the Two Bros. Racing and
then as I tried the bike on the road, with the standard air box and settings I had
with the Lasers, I realised that the new canisters needed more breathing and new
jetting for the bike was performing in a less than acceptable manner. The four K&N
filters have been quite drastic in what engine behaviour means, making the CV carbs
function in an irregular manner, upsetting all the conditions previously achieved, but
I firmly believe in Dynojet's approach to the Max carburetion and I'm aiming to get
it as close as possible to their demands.
As any medium knowledged mechanic would comprehend, if you understand how combustion
works, Dynojet makes it hard to believe that by removing the V-boost and leaving
straight through pipes, you can achieve good mid range power, so important to the
V-max, since that is where the low end torque depends on, but still I have been able
to feel and agree that one way or the other Dynojet have accomplished their goal,
since if anything my previous set-up with the Lasers was giving a lot more low end
torque than the standard system.
Now with the TBR racing canisters I find it much more difficult to get the mid range
torque. Following Dynojet's new recommendations (have been in constant contact with
them since all this started), I have moved the needle position to notch 5 from top
and the result has been for the better, but still my bike was able to produce far more
exhilarating acceleration marks when using the S7K and standard airbox, with the
Laser slip-ons. Today the rain was pouring down so I just rode the bike below the top
revs, but it behaved much better than yesterday when I had the needle position to max
fuel flow on the sixth notch position.
I have also been asked if I had changed the pilot air jet under the slide diaphragm to
190, but I have not. maybe I will, but not right now.
I know that open exhaust pipes will deliver better high end power by sacrificing mid
range power, but I hope I can come to terms with the system. My main goal is to have a
Max behaving like a Max, with tons of low end torque plus gaining some horse power at
the top end to be able to compare myself to the actual big sized engine bikes around.
If this mod I just made gives me top-end HP and looses mid range, then I don't want
it, my bike must outperform most of the actual bikes between 0-75 MPH and then let
them continue for that is their strong point and maxes do not or should not get
involved in high speed competition or road racing due to our obvious lack of fairing
and speed handling problems.
