Yeah I agree. I'm thinking that they were tack welded in a jig and then pushed down the assembly line to be fully welded with no support. Then once the welds cool it pulls all the bends out of line. I wasn't able to heat and bend the pipe like I hoped to either, it's going to take some welding to make them straight. I wish there was a better option for pipes in the US.

The whole stock exhaust is a goofy design. Probably had to meet strict noise regulations somewhere else in the world.

Tarazon is a reseller. Lots of cheap Chinese parts are floating around all over the place. Tarazon is some company with a warehouse that has figured out how to market and sell these parts on Amazon at a scale large enough to offset the import taxes. The pipes are crap. The parts are cheap. But nobody else sells pipes for this bike in the US. Many Chinese parts on Amazon from these unrecognizable brands are all the same thing that can often be found MUCH cheaper on Alibaba or aliexpress. Tarazon buys pallets of these from a direct supplier and then marks them up and sells them with prime shipping. These pipes are some kind of stainless so logic says they should last okay. I would expect your pipes would be from an entirely different manufacturer and factory, just sold by Tarazon. But if it's stainless it should last okay. Expect about the same quality I have, spotty.

Hopefully next weekend once this cold weather passes. I was planning on it last weekend when I found the flat front tire I fixed in my most recent video.

I was browsing Etsy for custom home made parts for this bike and did find one person who is welding intakes that adapt sideways so that you can mount a more traditional carburetor, but it would end up sticking out close to your knees depending on the carb and filter chosen

@@helloish12321 the Etsy ones don’t fit

@@Tonyjoanow thats a shame, saw some but cana remember where, not etsy

Yes. Until I rejetted the carb to compensate for the additional airflow the bike was backfiring as soon as you let off throttle and it was big loud pops. It still backfires after the rejet, but its that sort of subtle crackle backfiring when you downshift

I did but those listings tend to change. It's the first result when you search xv250 exhaust. They are also everywhere on eBay.

I think there used to be some kits available that went to 285cc. The problem is the bore of the case isn't wide enough for the piston skirt to travel all the way down so without boring out the case the kit can only get to 285

Yes you definitely have to. Right now I have only shimmed my needle up. I was actually going to film me putting new jets in today until I found a nail in my front tire 😁

I have seen an SR400 a few times and always have to stop and admire how many parts Yamaha was able to share between the two bikes. I love the look of the SR for sure and I would be easily convinced into buying one if I found one for sale. I didn't know that about the power though. My previous bike was a 250 single cylinder and I can tell you that while my last bike had more power there is something about having another cylinder that makes the engine more friendly and usable.

Yes! The mixture screw only really affects idle and very low throttle. Think of the difference in volume of air traveling at wide open throttle vs 1/8 throttle. If one small orifice could sufficiently meter fuel for such a variation of air flow then there would only need to be one jet and nothing else. The mixture screw is intended for quick adjustments to keep idle smooth at different temps and altitudes. The pilot jet adjusts fuel at lower throttle positions. The main jet determines the max gas flow (full throttle). And the needle determines how fast the rate of fuel increases as throttle increases up to the maximum determined by the main jet. All of them come together as a balance. It's the reason each one of these components is adjustable in the first place. Each bike is different, so I can't say yours will explode if you don't rejet but I felt like mine was very unhappy. Once I rejetted it ran cooler and was noticably faster. If you are going to put the pipes on why not go through the extra trouble to rejet and fully understand your machine.

@@helloish12321I have a 99 xv250 and after watching your videos I'm going to order a 122.5 main jet with a 22.5 pilot and 2 shims. Custom cold air intake (elbow with large pod filter) Iridium spark plugs (NGK) and the ebay $100 slash exhaust with silencers (2 inch). Universal 310 mm 12.5" rear gas/air shocks. I'm also debating on the sprockets so it's not constantly wound out in 5th. Any suggestions on sprockets size? 15 front/40 rear? Thanks for info!

I went up a tooth to 17 in the front and down 2 teeth to 43 in the rear. This dropped the revs about 10% on the highway and I can now stay at 70 all day without concern. I would order a selection of jets since every bike is different. In the end I found 20 idle and 120 main with 2 shims to work the best on mine. Once you have done it a few times changing jets is a breeze

If I was a writer I would write a novel about how quickly my hometown became ruined with money and commercialism. At the time I was determined to stay where I grew up. I have since moved to a much quieter town in a different state.

That's the oil capacity, 1.4L. I had the same confusion when I first bought the bike haha.

@@helloish12321 xD hahaha i thought its the oil capacity but why they put 1400 instead of 1.4, and even cm³ hahahahaha, watchin' video, wishing to buy this system but i live in serbia

But how much did it cost?

Was only the 3rd or so video I had made like this. I started doing a voice over afterwards
