why is that crazy? i'll be more than happy to give out my map for the turnone airbox and sato lows as soon as i get the stuff on and have the opportunity to get it down there.

as JBs_SP3 said, i'm not racing against anyone (and hell even if i was they could be running a stock production computer on a gp engine, i could have nitrous and a turbo and they would still beat my ass) so why does it matter? it's not like a custom map is the last can of soup in the pantry... no one is going to go hungry for sharing

Okay

Hey selfinfliction,... GREAT Idea, I wish I had thought of it like 3 or 4 months ago LOL...
selfinfliction cheap way to find out if it's getting too much air:

put duct tape covering 75% of the intake and go run it, then do 50% covered and 25% covered. will take about 5 minutes to find out

Hey "robfromsc"
To answer YOUR question Rob... YES I will try this out but not until "Spring", you live close enough to me I would think You've got to be having the same Freezing asz cold weather I am!.. So I will TEST this idea come spring... end of Feb. beginning of March... I'll reinstall it... Then I'll be ready to test it out when we have a freak warm day here or there..


JBs_SP3 I suspected your Baro sensor also. If the sensor's OK then I'm surprised (impressed?) your fueling is that much out.

Yes sir, I did try this as stated above in an eairly reply,.. I disconnected and reconnected.. NO change. And also Again,... IF this sensor was NFG.... would My RC51 be running Great in the mid and upper RPM ranges??... As mine was...?

The thing is here> I removed said snorkel and reinstalled OEM snorkel... and it runs Awesome!


Hey Mike aka El Pozzinator...
Great to see you here man, been along time eh! I will try and shoot you a PM within the next day or 3...



Thanks for your input as well here "wingnutt" PM coming your way too...

Thanks everyone, IF I missed someone.... sorry..

Peace Jeff

Im not even going to touch this one, except to say that theory if flawed. Think what you will be doing to the atmospheric pressure and the baro sensor. It would be highly unlikely just the difference in airflow between snorkels alone would cause any mapping problems. Your not getting "too much air".

After you put the OEM snorkel back on and the low end cleaned up, did you try the TurnOne snorkel again to verify the problem? I'm thinking you may have had a bad connection elsewhere in the wire harness, possibly effecting the baro sensor. What ever you disconnected and reconnected in the process of reinstalling the OEM snorkel is what probably fixed the problem.

[Turnone]

Highly unlikely to be an issue with any variation in airflow or restriction from the stock intake to the carbon intake.

Here's a couple of things to try,I've probably run through these with you before Jeff.

Check the Intake Baro sensor is working properly.
With the bike idling unplug and reconnect the wiring loom from the back of the sensor. If all is o.k. you should hear the idle and note change slightly.

Check the flapper vacuum hose is blocked off or has not come adrift further down the line or even come away from the front throttle body connection.

Cheers , Brett

[El Pozzinator]

good call brett... didn't think of the vaccuum hose. come to think of it, i prolly ought to recheck mine when i get home for thanksgiving.

[RCVTR]

JBs SP3, it sounds like your map sould be a decent starting place for my bike.

I'm running a T1 airbox and snorkel, full Moriwaki exhaust, pistons and minor head work.

I appreciate your willingness to share it. When I get mine fully dialled in, I'll pass it.

PM sent.

Cheers.

I've talked to Brett about it and I just wanted to ask, if any of you had problems as well?

After I installed said snorkel, (Beautifully Made!) My RC51 was running like CRAP in the RPM range say 3,300 RPM's and less, it was missing something horrible.... I made NO other changes.... anything over said RPM range, she ran Awesome!...
So I'm thinking a custom map right.... BUT why,.. when she was running so good before this mod., So before I start spending a bunch of money on a map, I figure I'm going to put the OEM back on first and see what happens....?
After I did the swap out and Installed OEM Ram Air Duct.... She was running as if it was never removed!.... KILLER!...

So,... have ALL you guys had custom maps made!??

TIA..

Peace

PS. I even put it up "for sale" and then had second thoughts.... LOL

I had...still have this same issue on mine. I had my bike dyno'ed and a custom map installed which helped a lot but did not totally eliminate problem. Do not have the stock snorkel to swap and see. Same rpm range you state too. I hope someone knows a fix because it would make me a very happy man!

The fix is to do the box and snorkel then get a map built by a good operator

hey man i'm running a similar setup now as well, have mild port work (just smoothed and all of the ledges removed) je pistons, t1 airbox, sato banzais and a hollowed out snorkel. hopefully my heads will be done tomorrow and we can start putting the baby back together this weekend. i would like to be on a dyno in 3 weeks max, and will be going to hordpower in ohio or hdf1 (iirc) in georgia to get the tune. will be happy to share with anyone who wants it. i am running a pc3usb now though instead of a pc3r i think the maps are interchangable right? except for the timing

the guy from hordpower seems to know his stuff, shouldn't be an issue to get up there and back i'll just take a day off work

The gentleman I had dyno my bike has been in the tuning biz for years. He has built numerous competitive race bikes for AMA, WERA, and CCS classes. I send my customers to him all the time all with positive results. I did not just take it to some joe smoe to blow up my RC with a s**t map. I do not have a box yet, I plan on this mod but want to wait for mrgrn exhaust so I can have them tuned together to save on dyno time which is $$$$$! He spent the majority of the time in the low rpms to smooth out low fueling issues. About 75-80% of the "jerkiness" was removed. The other bit I can deal with, just keep the revs up. Past 3400rpms she runs like a raped ape. Just saw someone else that had a similar issue and was wondering if there was something further to this annoyance.

Sorry if I came across as an asshole, and I'm not questioning any operators ability.

Just trying to promote the hidden potential these motors have...
the ride home from the day of purchase was a HUGE dissapointment followed by a custom map and some sato lows.
Then came suspension.
The base line for acceleration was my "84 fj 1100 which still kept pace

Then the realisation that the best weight / power combo could be had by getting the box/snorkel/dyno completed at once was tantamount... no hardware mod collection will yeild crisp responce without it ... AND beleive ME when I tell you this one is linear

[hawkman996]

I figured the low fueling issue may have been more the Jardine 2:1 fault then then the snorkel, but I see now someone else has this issue. Just wondering if this was a known issue with a possible simple fix.

I know you were not trying to be an arse, I was just stating the facts so all was known. I have seen some horrible dyno operators and the sorry affects of their maps.

I rode a customer's RC with sato lows, T1 box/snorkel and it ripped. From about 5-5500rpm it felt similar to mine, pulled harder past 7500-8rpm on up, and did not have low rpm hick-ups like mine. I liked the stronger bottom with 2:2 setup though. I know you can still get the hp up top and some in low/mid with 2:2 without losing on the bottom like my 2:1.

My bike was noticeably better after the tune. Much smoother/crisper in mid to high, where it just keeps pulling, but that "jerkiness" below 3400rpm is an annoyance I can live with but would like to remedy if possible. The gentleman who owned my beast before me just downloaded a sato-low map and while it was a nice try, only the custom map would work.

Once mrgrn has the 2:2 full ready and I have either a T1 or thorsten box installed I will retune. I am excited and optimistic about the results.

I wish taking my bike to JD Hord was an option. Jealous as hell. If you do please post up the results.

will do man, he's only about 5 hours away and the same price as the local shops, it's dumb for me not to take advantage

[CBR400RR]

I don't think any RC51 stock or not likes to be ridden below 3K rpm.

Jeff,
Did you ever get this sorted out??? I added the snorkel and had *0* issues.. I did however have it reDyno'd and map was changed a tad bit..but it was all on the higher values nothing down low.
