Forum: Fuel and exhaust system

I've decided to balance the carbs myself and I was wondering if there is anyone in the wellington area who might be kind enough to loan me a vacum meter? I know it's a bit of an ask but I thought I'd check before I start making my own out of bits of hose!

Well my bike (GSX400F)has been acting up lately, not smoothly idling below 2500rpm and when warm will raise to 3000. Any attempt to lower the idle by using the idle screw results in dropping away from 3000 down to 750 then dieing. I thought the idle jets could be blocked since it worked fine at...

Ok I've just got some after market exhaust for my VTR1000 and when I start the engine I feel a leak comming out from where the mid pipe connects and you have that ring bolt thingy. Now I supect the pipe(tht came with the cans) may be slightly out of shape as the left hand side exhaust has no...

As my "big wheels" licence approaches, I've got my eye keenly on a new Bonneville SE. Now, one of the first jobs is gonna be to replace the mufflers. The Arrow jobs are 3K, which I reckon is a bit steep. Would appreciate any advice on an alternative product. And, any advice on impact of...

I have just bought a new GS1200ss muffler ($1.50 from TM :yes:). I am wondering if the guts of it can be rebuilt to give the benefits that can be got from an aftermarket (sound, power). It ought to be cheaper as the shell and pipe will fit without having to be built, saving materials and time....

So my mate has some heat wrapping left from working on his car (to stop the pipes cooking things, not some mythical performance gain) and I was thinking about using the leftovers on my NC35 to wrap up the two rear header from where they exit the motor up to where they end behind the heat shield (if...

Seems a bit too simple to me but I chanced accross a web page with some instructions and did some more research, turns out you can clean them with electrolosis, apparently! I've currently got 1 bowl sat in a bucket happily bubbling away as a test, just wondering if anyone else had tried this and...

I have been doing some light reading on the pros and cons of CV carbs. I have found that they are fantastic for smoothing out power delivery due to the equalizing of pressure etc yah de yah. What I have noticed however is that nowhere does it mention they are good for much else.. If I was so...

Quick question folks, just been taking the bike apart to have a look at stuff (first time I've been able to take a look since I purchased it) anyhow I noticed under the seat there was this thing that looked like there should be cables coming out of somewhere and going into it :(, himmm me thinks I...

Hi, I've been lucky in getting a NOS (new old stock) fuel tank for an early 70's Yamaha 2 stroke twin. Unfortunately after the fuel tanks first filling up of fuel I notice some light surface rust appearing :gob:(I am keeping the tank full when storing to prevent condensation build up - just...

Hey all, I have a 1990 CBR250RR with a bit of a prob........ it leaks gas out of the breather nipple(I think) at the top of the fuel tap located under the gas tank. Been doing this for a while now so I thought I might try for some insight here. Recently I changed the fuel tap when I first...

Is there anyone deals in 2 brothers exhaust..Am after one for gsx750f katana..

In your personal experience, was disconnecting the intake flapper on this bike worth doing, in regards to unleashing some power between 3000 and 6000 RPM. /edit: And yes, I'm aware of the ridiculousness of asking how to make a bike like this make more power on the street

Anyone thought of making an alloy fuel tank from scratch? Nothing too complicated, perhaps ; <img src="http://www.fahrtbier.de/wp-content/uploads/2009/02/horex-cafe-racer.jpg" width="480" height="320"> <img src="http://www.eurospares.com/graphics/carlyam3.jpg"> <img...

Hows it goin... I am looking at putting an aftermarket exhaust on my 04' GSX250 as it sounds like a sewing machine through earmuffs, seriously it does!! ... not a nice sound :wacko: I have seen a GSXR250 with a yoshi muffler and that looked good, I can't seem to find anything like this for a...

Can someone help with a sticking throttle problem I have with the Trophy. The throttle will hang on for about 10 seconds if rolled off, but if u snap it off or let it go it comes back to idle as normal. Cheers Dan

The only change I've made since it was running fine was that I've put Gull Force 10 (ethanol blend) in the tank. Is it possible for a bike to run fine on idle and then have one cylinder pack up under load due to contaminants in one of the carbs? Or should I be focusing my efforts on the ignition...

I recently got my ZXR250 so I'm not the proud owner of a project, hopefully just a little one to get me started :) So far I've removed all the stuff that gets in the way (farings, tank, radiator, air box) and got the carbs off. I'm in the middle of cleaning up the carbs and it's a bit of a...

My bike is a 08 CBR600RR. It has a Yoshi RS-5 slip-on only (stock headers and cat). It is due for a replacement air filter but the stock filters are on backorder from Japan and will take 2-4 weeks. They also cost a little bit more than an aftermarket K&N from bits4bikes. I'm not looking for...

have put a 1978 dr 370 into a 1986 dr250 frame, running it on the 250 carb as needed to clean up the 370 carb. spent hours cleaning up the 370 carb and upon fitting it is 12 mm higher and wont fit as the frame is to close, bugggar will the carb run on a 30 deg angle? can i drill out the...

I have a Rt 180 or Dt 175 almost same parts that fit. How far in the header pipe is the washer? Is it a pull out affair or do I have to cut it out? And Does anyone know any aftermarket parts or how to add more power, i noticed that the yamaha blaster has the same head would that be worth trying,...

Can anyone tell me where I can find carbon pipes for The Ducati? I smashed one , but these were one offs so need a new set. Any ideas greatfully appreciated:Oops:
