I have a KLR650 jetkit, never been used jet kit for sale for R400. I purchased it, but never got to use it. PM me if you are interested.

Here is another suggestion. Most spare shops sell exhaust header warp. It is normally used to wrap around exhaust headers where it leaves the head to keep heat inside the exhaust pipe and less heat from getting to the engine compartment. You can try and wrap this stuff around the header...

You get a very high heat tolerant, copper based silicone sealer. Cannot remember the name right now, but comes in a blue and copper coloured tube. I use it when dyno tuning bikes and need to seal up the exhaust. Not all spare shops stock this stuff, but found some at a Midas near me not so long...

Hi there. Powercommanders does not necessarily add more power. They fix fuel problems. The more fuel problems you have the bigger the performance gains. The biggest gains, between 4 to 6 HP on an XT comes from the stage 2 or 3 filter, with a powercommander. Exhaust gains max 1 HP at peak...

Your choices are limited in Sa since you only get a few pipe sizes with the correct pre-made bends. Hadrly anyone here in Sa bends the pipe, and those that do tend to mess them up. Trust me, just use the standard 38mm pipes as a start and go from there. some guys use a picture of another well...

A supertrapp is not a real tuneable exhaust. Yes you can change the flow of the exhaust by changing the back pressure and sound output, but a true tuneable exhaust is one that you can change the length of the header pipes or maybe even the diameter to change the exhaust harmonics to promote...

Most stock exhaust systems these days are not half bad. The days where a simple silencer swap gives you a 10 to 20% gain in power is almost gone. On most superbikes, the gains you get from a full race system versus stock is like 2 to 4 % max. Most change it purely for a weight saving, no so...

There is no such thing as an engine that needs back pressure. People break engines and burns valves because they fit high flow exhaust systems and never bother to adjust the fuel delivery to the correct levels to compensate for the better exhaust flow. There is no such thing as the best...

38mm is normally the outside diameter of the pipe and they are normally 1.5mm thick. Inside diameter is around 35mm. Don't go bigger than 38mm, but also, make sure that the head can actually handle that size headers. You can contact Stealth Exhaust in Pretoria. They can fabricate any headers...

Where did you get your jetting information from? Be very careful about jetting info on the web. the needle clip position and main jet size depends on air pressure, mostly affected by altitude, air temperature and then the mods you run on your bike. You cannot use the jetting info from some...

Yea, as long as those before and after readings are on the same dyno!!! ;D " That statement is not ever true. Even if you use the same dyno, did you know that you can lower or increase Horsepower reading by simply changing tyre pressure? Some not so honest dyno operators will dyno the bike...

Hi guys. Your welcome to ask questions. If you dont ask, you will never learn. My dyno reads very low and like Kykdaar said, my dyno measures the rear wheel Horsepower applied to the road. Almost every other dyno in SA, especially the Hyperpower dynos most shops use is set to display predicted...

Glad you like the outcome. Was fun working on your bike. enjoy the upcoming trip.

Hi all. The dyno is fixed again after endless waiting.

In some cases a red exhaust at idle is normal on very thin exhaust header pipes, but if you are not running a stock engine, a red header pipe at idle normally mean the bike is running lean. Most guys fit aftermarket air filters, free flowing exhaust systems and not addressing the fuel delivery...

I am based in Centurion. Dynojet jet kits normally sells for around R500 to R600 at most bike shops. Other brands of jet kits like JD jets, sell for R750 to R1000 at most shops. With the kit you get a new performance needle, and a selection of main jets, to work with most setups. Some kits...

TFI, EFI, all the same thing.  https://www.techlusion.com/ Techlusion make the unit and different companies, like DMC put their name on it. Yes you have 5 settings, but a lot fo them are not much use. Setting 1 only adjust idle, nothing else. Setting 2 is for accelerator pump. IT;s a setting...

There is a massive difference between what a powercommander gives you versus a TFI. TFI, can only add fuel up to a max of 20% more. Powercommander can add AND remove fuel. 200% more and 100% less than stock can be changed with the powercommander. Why is that important? I have never tuned a bike...

Just a few things. DNA stage 3 filters are currently not available in SA. I have requested that the local importer get some, but not sure when they will arrive. currently, if you want one, you can order it on XT660.com's web site. Takes about a week to arrive via UPS. Most people who ordered...

We actually took the puig screen and cut it in half. It is about 3/4 of the hight of the stock screen. The puig screen also comes with a rubber edge which we used to round it off nicely. Looks like it was bought like that. The best if you are going to do this is to chop it off in stages until...
