Full system exhausts

[Toast]

How many here have put a full system on their bike and had to remove the back pressure valve thing by whichever name it goes on the particular bike?

I just put one on and it's mean, except runs like a mutt with bird flu below 2000rpm. Now I never thought this would be a problem, but I've started a new job this week and commuting to work is a pain in the ass, especially in the wet when you've got to ride the clutch while doing a u-turn in front of an oncoming bus.

Will getting a custom map help this particular problem much?

Where's the best place to go for one? I was going to go to Ray Clee, figuring he'd have a bit of knowledge about this stuff, but the seller recommended GP Motorcycles in Tauranga, saying that they had the DynoJet Dyno or something like that.

Recommendations?

Cheers

[bugjuice]

thought about a power commander to help the issue? eBay is a cheap place to look..


oh, and if a cop sees you pulling right out of the drive on a no-right junction, nail it, or go up the road a bit and pull into one of the drives on the right next to the bus shelter ;)

[Toast]

Got a PC3 already actually BJ...it does fuel better than before once past that 2 thou' mark...

haha...I'm bound to get sprung going right towards the South-bound motorway on-ramp some day soon...

[bugjuice]

have you had it remapped since you installed the system?

just turn left out the drive, go into the middle of the road, then turn right into the bus stop/drive, then just nail it.. I do it all the time. It's a U turn then, and there's nothing wrong with U turns :bleh:

[White trash]

Anything GP trading can do, Ray Clee can do better. Difference is, how much do you wanna spend?

There's a reason Andrew Stroud and Ray are always at the front mate.

(This is no way a dig at GP trading. They do good work at a good price)

[Toast]

Yeah, I've got a bit of faith in the Ray Clee name, I'm sure he can do a good job.

I don't mind paying a bit more to get it done absolutely right. $200ish, $300 at most. It wouldn't cost more than this I assume?

Yeah there was a bit of traffic today so I did that...but if it's clear I can't be arsed and just gun it. That new on-ramp layout has quite a nice corner, and you're protected from the view of the motorway traffic for a few metres so can pull a sneaky little wheelie without much risk if you feel the need :niceone: (which you do after work)

Ah, I was hoping you wouldn't ask Winja...it's a 'FUCKIN SACK OF SHIT HONDA FIREBLADE (929) THAT'S NOT EVEN AS FAST AS A GIXXER 750'.

Actually it's not as fast as a K1 or later 750 I don't reckon. Goes ok up to 240 but I think from then on it's really missing the ram air...struggles a bit. Won't be a bad bike once the forks are sorted.

ITS PROLLY A BIT RICH DOWN LOW AND A LITTLE LEAN UP TOP ,IT DONT SOUND LIKE ROCKET SCIENCE TO SORT OUT.
IS THE AIR FILTER CLEAN?

hav you had a search on the net for the right fuel map for your exhuast?

I think the filter is ok.

Shouldn't take much sorting from a pro...and it will be better everywhere else too...

I got this second hand...I'm just using the one that the previous owner had on there, which he said was the one for the exhaust.

(edit: the exhaust and PC3 came from the same dude)

[cowpoos]

have a look on www.dynojet.com search through the fuel maps...see if theres some thing there to try....no harm in trying.... might save ya alot of $$$ if something works well!!

Cheers poos, I'll take a look at that.

All the Americans reckon that there's nothing quite like a custom map, but yeah, I'll try these ones first, definitely no harm in trying. Gotta get the bike out of shit city more though, so that I can assess the performance at higher rpm's.

[Fishy]

Hey Toast, you could take it in to AMPS and get them to sort it out on the dyno. They will be able to get it sorted pretty quickly. Probably cost ya a couple hundy.

They sell install and dyno tune bikes with aftermarket pipes and PC's.

[Cajun]

Really depends on where you are i guess,
AMPS - AKL
GP Trading - TGA
Ray Clee - Wherever he is
WMC - Wellington

Dyno should cost you $200-$300 i guess, takes a few runs to figure out the best map to use with your bike, you will notice a hell of a difference in the bikes power, and more likley than not get better fuel milage.

THe basic maps are fine from the website they are just a guide tho, since very bike is different really.

[montsta56]

Go an see Gary an the boys a GP honda , Gary's a master on the dyno he'll have it purring in no time flat,. They look after all my bikes an I think there the best goin round.Well priced to!!!!

[Cajun]

hey monststa you should come say hello at navagitor at mount one thrusday evening.

alot of us meet up there

I was actually quite disappointed that he didn't give me the 'you're gonna need more than a custom map to learn me, sonny' treatment...it just doesn't feel the same :(

WINJA also didn't shit on the Fireblade...must be Easter cheer, such a pious soul he is.

If AMPS is decent I might go to them, then. They're about 10 mins from my place, and open on weekend mornings, which I doubt Ray Clee is. Ray's in the whops too.

Nothing wrong with 929 Blades, must be the rider. My old one had a Micron and ran shit hot at any revs.
Since you seem to hate your choice of bike so much and slag it off, do the bike a favour and buy something else.

Did I say I hate it? You may have noted the CAPS in the description of the bike, imitating how WINJA normally describes the 'Blade family. It wasn't exactly subtle.

They are a really goodbike, especially on the road, but they're not really powerful, the 0.7kg/mm springs up front are way too soft to be used hard by someone heavy, and many a magazine has found a Gixxer 750 to be a quicker bike.

Your 929 probably ran well at all revs because it only had the end can, and still had the exhaust valve in there doing its thing at lower revs.

All make sense to you now?

[WINJA]

funny thing about the first blade , when you put just an end can on some of them it would run real shitty, one fix was to pull the end can apart and ding the perf tube slightly with a ball peen hammer at the inlet then go 180 deg round the tube and put another ding at the other end , that slight restriction was enough back preasure to clear it up , i think 2 brothers even bought a can out like that

Doesn't that kinda kill the purpose of putting a can that allows more air to flow in the first place? Or is the air flow and the back pressure not directly related?

WITH A COUPLE OF SMALL DINGS IT WOULD STILL FLOW MORE, THEY ARE RELATED MORE BACK PREASURE LESS FLOW. BUT THERES MORE TO EXHAUSTS THAN YOUD THINK , IT MAY HAVE SOMETHING TO DO WITH CAM OVERLAP AS MUCH AS FUELING , MOTU WOULD KNOW

Ok Sarcasm doesn't come across when reading it. Agreed, they are are good bike. From memory mine had the valve thingy closed over (sort of welded shut) on the connecting pipe an inch or so before it fed into the Micron muffler. Whatever, the bike ran bloody well and pulled hard way passed 260kph mark. I didn't have any issues with the forks?
A KBer owns mine now down south and he's happy as with it.
I've just fitted a Micron to the 636 a few days ago and the kit came with instructions and bits and pieces to take care of the exhaust valve - a clever gadget to fool the sytem management/ignition check so the FI warning light wont stay on or register a fault. Sounds sweet and I weighed the original muffler 5.9kg and the Micron ... 1.9kg

That's pretty interesing that the valve was closed over and it still ran well.

I had the bike to 265 idicated with the stock kit...so will be interested to see what it will do under the same conditions with the new stuff.

Micron is classy kit...woulda liked summat, but just got this at a good price.

Are you quite light? I'm 85kg, and have had the forks bottom out under braking in the wet...not nice. To be honest being smoother coming in to them would help...but I've decided that I will change the spring to suit me instead of changing me to suit the bike.

a gsxr750 is faster than that...infact jimbo600 ran a trap speed on the flying quarter at about that on his k4 gsxr600

The bike had more in it, but not heaps more...the Gix would beat it.

If Jimbo set that kind of trap speed then the 216km/h or whatever I was reading that 2much's trap speed at the end of his 10.6 second quarter mile looks a bit sick in comparison.

One piece of info above has been slightly skewed (likely mistakenly)...and since I don't think I've ever seen a recorded trap speed in the 260 region for a 600 hundy, I'll vote for Jimbo's actual trap speed being much less.

The 'Blade actually storms to 240...but the acceleratin slows a bit after that. As above, I blame the lack of ram air, that shit really works.

flying quarter...not standing.... get massive run up and rev the shit outta it and hold iit between two timing markers...they run that and the standing drags in the wairarapa at times....havn't been yet....but alot of the welly crew have...

[jahrasti]

I am not to familiar with your exhaust valve, does it have an elec motor controlling it? The reason i ask is I fitted a Muzzys slipon and PC3 well it had a counterweight which replaced the stock powervalve.Problems was that there was not enough resistance on the counterweight which told the puter to not run correctly.A screw inserted on one side of the counterweight and it was fixed.The Pc was matched to the slipon and it ran fine on the program that it came with but I was advised to get a custom map fitted. I did and it did make an improvement.

[Goblin]

Hey Toast....I hope you dont mind me asking a question in your thread. I've bought 2much's end can off his old Triumph 600 & had it fitted yesterday. Now being a crappy old Honda with carbs etc....do I need to get it tuned for the can? After riding 2much's K3 Thou for a few hours,(Thanks Mark!) getting back on my bike was a step down but it had 91 petrol in it. I filled up with 98 when I got back and in about 10km it really improved. There's no backfiring and seems to be revving alot free-er. It sounds loud, deep & throaty. More like a thou than a 6 hundy. When I got home I checked it again and there's a leak around the flange. The motor makes a strange little noise at the start of a blip of the throttle. I'm sposed to be doing an east coast ride on Sunday & really dont want to blow my motor up. Will it be OK? I feel like I need an expert to check over it before I start to thrash it again. I've always thought that you shouldnt go fiddling if things are working. which is why Ive never changed the plugs or fiddled with it.

start a thread doll....see if you can find a member whos a mechanic or mechanically minded close by...you might get lucky eh?

[WINJA]

GOBLINif its just a leak where the flange meets the muffler you can usually seal it with a bit of roofing silicone on the sealing faces or in some cases ive just pulled the sealing ring out of an old oil filter and used that.
if its a swage your talking about you can also use roofing silicone in there.
make sure you use neutral cure silicone an the acetic cure can cause corrosion after time , leave over night to cure

[Goblin]

Thanks WINJA... Wouldn't roofing silicone be affected by the heat? I might go buy some propper gasket stuff when the shops open again.

Poos, I dont think its worth starting a new thread. I'll just take it easy on Sunday & hope for the best. :rolleyes:

[aff-man]

hmmmm totally different bike... but I got a full arrow system on mine... and due to it being a carby its gutless below 3000rpm...

That's fine with me though cause you really gotta make her scream to do anything.

Yep, there is a little motor just under the seat that was controlling the valve. The motor is still there so I'm guessing it's still turning around at lower revs when the throttle is applied, but I keep forgetting to have a look under when I'm near the bike.

Never heard of this counterweight thing. Is this on your 636? Where is the valve on one of these? Is it in the mid pipe?

I'm 75kg Toast but even with another 10kg on board I wouldn't expect to be able to make the forks bottom out if I tried. I think you're right, get the springs changed. Maybe some fat bugger before you ruined them. Good luck sorting the muffler, I'm no mechanic so can't offer any advice. I've got to say though that since I fitted the Micron to the 636 it's bloody fantastic. Top sound and just when I couldn't expect any better acceleration from a 636cc engine it's gone and raised the bar higher. Riding is bliss!
