Bought one last year, in Sweden. Go for it!

@@greyriddance64 I Bought one a week ago. Love it, just need to change to a more comfortable handle bar.

Hi! All of our parts can be purchased from Modeliko Cafe Racers and you can check with them which countries they ship to. Thanks! modelikocaferacers.com/gb/281-jadus-motorcycles

Hi! Great you managed to remove them. You will most likely not need to adjust your main jets but you should definitely adjust your air/fuel screw setting to allow more fuel at low rpms. It should be adjusted to between 3-4 turns out.

Yes, the kit comes with a range of jets that suit several different exhaust set ups, including straight pipes :)

Could be. If so, it would be quite a sever one!

If you have the stock intake, you most likely will not need to adjust the main jets. But you should definitely adjust the air/fuel screw so that it is between 3-4 turns out. This is so you allow more fuel to flow at lower rpms. If you have a modified intake you should adjust the main jets as well.

@mcrand7887 Thanks for your concern, but in this case, the plastic parts need to be removed to be able to install this particular replacement diaphragm. There are other kits that have different designs, but we do not have any experience with them. We have the same response to your inquiry about the lower plastic ring. And you are incorrect on your third assumption about the lower ring needing to be there to form a seal and to keep fuel away from the diaphragm. This replacement becomes the new seal and maintains the original dimensions of the original diaphragm, just with one part instead of a three part design. The rubber of these diaphragms is also extremely durable and tolerant of fuel, so if they get fuel on them it is not a concern at all. All the best!

Yes ☺

Hi Jo, most likely not. Most hubs have different spoke hole spacing's and diameters so the spoke lengths would be different.

@@JadusMotorcycleParts Thanks Jake.

The batteries are listed here: www.jadusmotorcycleparts.com/product-page/sr250-frame-triangle-tidy-kit

Thanks! This is a cheap WD-40 equivalent :)

Hi! I am not sure what you mean… Do you mean the oil filler cap? The stock one is plastic and the one I have installed here is a metal one with an oil temperature guage in it!

It depends... old bikes in general leak oil in some places due to different reasons. It could be just a simple thing like a tired hardened oring that isn't forming a seal any more... or it could be leaking from around the cam chain tunnel... those things are no big deal. As long as you keep an eye on the oil level until you decide to replace orings and gaskets etc. It is worse if the head is leaking oil through the valve seals, then the engine performance is affected. It is also more difficult to replace those seals - it is often a head-off job.

@@JadusMotorcycleParts life saver. Thank you 😘

Different models and years have different stock main jets. We send a range of jets in the kit with a jetting guide so that customers can match jetting to their exhaust system. This also allows for carb adjustments down the road if you want to install a different exhaust system :)

Sure did! We're taking our time making a video about it ☺

Great idea!

Unfortunately not (that we know know of). We called our first pipe 'Low Slung' because we had intensions of doing a high pipe. But sadly it never happened... I wonder how much interest there would be in such a pipe?

Yamaha engineers spent a lot of time optimising the original system, so the flow of the primary pipes to the collector is not very restricted. Then the silencer has a lot of volume, so there is not a huge restriction there either. This aftermarket system may have better flow in the primary pipes, but the silencers are a terrible 'interference' design which reduces noise yes, but also kills gas flow. As mentioned in the video, the aftermarket system is nice from a cosmetic standpoint (yes, stainless, very nice) but not from a performance standpoint.

@@JadusMotorcycleParts I see. What are your views on the new improved version which they specify has been "Upgraded in 2022 to unleash your Virago to its highest potential" and have "Improved gas flow with deeper tone." Quotes taken from their website. The silencers are removable in the new version, but I suppose they used similar marketing for the version you tested which showed it in fact did not improve gas flow or unleash your Virago to its highest potential. If the silencers are the problem and they are removable on the new version do you think there is hope for it?

@@brian100pd Good question. I could speculate here but I won't because I see no reason why they could not just do a dyno test and back their statements up with numbers. You could reach out to them and ask them!

@@JadusMotorcycleParts I have actually contacted them already with a much more simple query and they weren't able to give any useful information, so as much as id like some information on their exhaust systems and not just empty statements saying "its great", i'm certain there's no point in asking them for it. If the development of the system involved anything more than "make a pipe that fits the bike" then like you, I cant see why they wouldn't share some of that info in their advertising to boost sales. Maybe the fact that your dyno testing showed it to be worse than the original answers that.

@@brian100pd Most likely! Dyno testing is time consuming and expensive, and doesn't always show the results you want/were hoping for! On another note, their drag pipes work quite well, but maybe that was a fluke ;) At least we at Jadus did some testing with it!

The manual states 7.2ft-lb for the long oil filter cover bolts and for the crank case cover bolts it specifies 5.1ft-lb. But these settings are so low, we usually just do these up by feeling - tight enough but not too tight!

The fuel in the float bowl must be going somewhere and emptying it. You should not need to use the PRI (prime) position every time you start the bike. It is only needed if the bike has been sitting for a long time and the fuel in the float bowl has evaporated, or you have just rebuilt the carb and need to fill the float bowl again. My best advise is to rebuild the petcock (fuel tap). It sounds like you problem is there. But it is always good advice to rebuild the carb on old bikes as well because I still suspect your float valve is not working correctly.

@@JadusMotorcycleParts Thank you very much. I will also be replacing the intake manifold as I have noticed a few small air bubbles when spraying petroleum jelly while the bike is running. One question: In addition to its "paper" seal, should a high-temperature sealing paste also be applied?

Hi! That is unfortunate! Yes, you float valve is probably worn and not seating properly, therefore leaking. There are rebuild kits available and it is pretty easy to replace :) Just make sure that no fuel got into the engine/engine oil.

@@JadusMotorcycleParts Hello again, thanks for the reply. Sorry if I bore you, but I need your opinion and your help. Two days ago, after having cleaned the carburettor well, I started the SR250 after years of standstill. As I already wrote to you, in the PRI position for about 1 minute, gasoline flowed out of the air filter exhaust pipe. When I put the fuel cock to ON, the fuel stopped coming out, and the bike started easily even using full choke. Today, when I went to turn it on, inserting only the whole choke, the bike started up, after a while it went out and didn't want to start again, as if no petrol was arriving. Not even when pushed downhill did it start. I then put the petcock back to the PRI position, and after nearly a minute in this position, petrol was NOT flowing out of the air cleaner drain pipe like it did two days ago. I put it back ON, tried to turn it on and this time the bike started. What did you understand? Why do you think this happens, where is the problem? I think it is incorrect that after two days, you need to put the tap on PRI to start it. I repeat, I had the sensation that no petrol was arriving to be able to light. Help me understand where I need to intervene. Thank you very much.

In other words, can I avoid to empty the oil motor if I remove the right crankcase cover?

@@ivandepasquale2717 Hi Ivan, not if the bike is level. But if you lean it to the left side you can!

@@JadusMotorcycleParts First of all, many thanks. In your opinion, could be enough to lean the bike on the left side stand?

Hi Hampus, the kit comes with a selection of jets so that you can install the ones that suit your exhaust :)
