Excellent jets

went to swap jets on my crf450r, main jet threads snapped off into the jet holder tube, I didn't over torque it. it's just weak material.luckily I was able to back the threads out, not worth risking a day of riding over.

many spares in kit

Upon recieving this product, I immediately noticed how jambled in the box they were in. Now this isn't the real issue for the two stars, but I have had jets damaged once before by this kind of packaging as the smashing around can beat up brass quite easily, just a suggestion.Upon buying, I was under the impression they fit my 19mm CVK carb. No size was specified, thus implying it would fit a CVK. So why doesn't it fit? thats because the main jets are not for my smaller carb. This should have been specified, $10 parts or not. Bad for business. This cost them 2 stars at the most because that's how you sell parts, specifying what parts you are selling. Or you should at the least know.They lost another star because two of the pilot jets STILL HAD METAL BURS IN THEM, one ready to fly. As in, the holes were not completely cleaned!! And it was facing upwards, able to be pulled INTO THE INTAKE. Last I checked, brass + valve seat = bad day. At least check the quality control of your product. Also, do be careful as the brass on these jets is very soft.All in all, I should have just bought a professional quality kit even though I was only going to use it once. I was a lucky minority to get a burred up jet I think. If you do buy them, the description is not accurate, these are not universal nor will they fit all of what is in the description. Importantly, will not fit 19mm CVK carbs.Giving two stars because it arrived somewhat on the delivery time, though it said they were supposed to arrive a lot earlier yesterday. Better than nothing at all! If you need them and have a bigger carb, get em. But don't be saddened if it does or doesnt fit.
