【CBR250R⑤】良い音出る マフラー完成！100Vノンガス半自動溶接でマフラーを改造してみたら予想以上の出来栄えでした（半自動溶接）

#YouthBike #RacerReplica #CBR250R I bought a 1988 CBR250R (MC19) on Yahoo! Auctions (not Ni-dabo, it's Ni-hari!) I want to enjoy the roar of the 18,000 rpm super high-revving engine even more! So I'm going to modify the muffler. I cut the standard muffler in half with a band saw and welded a general-purpose silencer to it! I got the sound I wanted - yay! Success!! Welding is really fun. 0:00 This time it's welding! I'm going to modify the CBR250R muffler 0:58 Suddenly a problem occurs! I'll try using "Mag Earth" 1:39 First of all, spot welding 2:28 Now it's time for the real welding! 3:55 Muffler is finished~~ 5:35 Start the engine! What kind of sound will the muffler make?! 6:03 Comparing exhaust sounds (This item) ・Star Electric Manufacturing (SUZUKID) MagEarth 200 P-740 　https://amzn.to/33FgK78 ・Star Electric Manufacturing (SUZUKID) Liquid crystal automatic darkening welding mask Eyeborg αII - Blue filter - EB-200A2B 　https://amzn.to/3bd1X7C ・[Star Electric Manufacturing (SUZUKID)] Inverter non-gas semi-automatic welding machine Buddy SBD-80 (¥32,800) 　https://amzn.to/3lMsMSz ・Carbon spatter sheet (bonfire sheet) 　https://amzn.to/33EDV1a ・(¥4,260) Jinmu slip-on muffler motorcycle silencer universal 38mm-50.8mm https://amzn.to/39tn0AG? ※We use the Amazon Associates Program.
