Finally Done With Nev's Cams

[Jethro]

Here's the new dyno runs with the new cams. I still have more tweaking
to do, but this will give you guys a good idea of what to expect.
It only looks like a 8HP gain, but above 4000rpms the bike screams.
It also seems to rev much faster. In first gear if you nail it over 3000rpms
the back tire starts to spin while the front end comes up ( pretty radical ).
So far I'm happy with what I did, but like I said its not tweaked at all. I'm
sure I can get a few more horses out of it.

Good job, Jethro! I suspected you would be over 160 HP, but look at the improvement in your torque curve! In reality, I bet your bike is MUCH faster. You could use TuneBoy to change your fuel cut to 6800, tune to 7000, and get even more. How was the installation?

Check your PM.

That's an excellent point Hombre, and a point well-taken.

I should have been more specific when talking about acceleration. I was referring more to roll-ons, cruising at 2500 RPMs or so and just getting all over it for a few seconds. Mild entertainment compared to 1/4 mile runs and top speed shootouts, but then again, my skill level is mild. :lol:

Yeah, occassionally I do some fast-ass stuff and will be shifting like Hombre said, around 4500, using 2 gears, but that's very minimal compared to the roll-on thing that I do many times on a daily basis.

Hey, I'm happy that the cams are what ya all need. It doesn't seem like they're for me though.

I'm looking for something that will increase the powerband in the lower to mid RPMs. I might be dreaming too. Maybe my riding style will limit how many more mods I can do.

Anyway enough about my tame riding.

So the sound...was there a difference in the sound of your engine with those cams Jethro? Does the idle sound any different?

At idle it sounds the same, but above 4000rpms at hard throttle it seems to go through the rpm range much quicker and definitely sounds meaner.

Seat of the pants, the bike seems much more powerful. It's somewhat like when I went from the stock intake to the triples.

So far I'm happy, but I've still got more tweaking to do.

Congrats...now you should be able to beat me

J-Ro has about 2-4 more RWHP in his system if he bumps the revs and plays with the timing via the TB.

And personally I would trade some low end grunt gor high RPM pull...

once again I find myself in the land of GIANTS! Someday, maybe, I'll make it to the big league. In the mean time, I'll remain content with my ass-slinging stock beast. Woohooo!!!

 

[Jethro]

Nice one jethro .......good to see you are pleased with the result, it seems to be on par with what you would expect from the mild cams...........enjoy :wink:

Thank you, I appreciate that, also thanks for your help with this and my

triples last year.

Congrats...now you should be able to beat me

:twisted: I didn't need the cams for that. :twisted:

J-Ro has about 2-4 more RWHP in his system if he bumps the revs and plays with the timing via the TB.

I forgot to mention that the bike hasn't even been remapped yet. We just

dynoed the bike after the cams install and a 7 mile test ride waiting for the

check engine light to go off. After remap, possibly with TB, I will post new

charts.

 

[MiamiDave]

I didn't know that either (but we talked about it).

I suspected he did remap some WOT runs (the easiest to map for straight A/F) in order to make power and be safe.

The full remap will give you more juice under WOT, but still will have a positive effect on the dyno. Not to sound like a naysayer, I think he will only see 1-2 more HP but a bit more TQ with the full remap (alone).

I would love to see 15 more RWHP with the cams alone, but I don't think so.

Nev was balls on dead accurate though in his original RWHP estimations, which was equally impressive.

 

[Jethro]

Jethro, why didn't you say so?!? That changes everything... I bet with remap you'll be at 165 HP and the torque curve will look even better! BTW, with TuneBoy you could read that DTC (engine light) and then shut it off.

Like I said on another thread somewhere, I'm not the sharpest knife in the kitchen. Why do you think they call me Jethro.

Yeah, I agree with you about the increase with remap, give or take a hp.
It's mainly the dips in the lower rpm range I want to work on, maybe
starving for fuel.

The engine light went off after the 7 mile test ride by itself, but I do need
the TB for further tuning among the other things.
