Did you break in that piston and cylinder? Pretty important when you want to keep your compression over longer periods of time! Sounds damn awesome

[@blazexiytb]

Break in?

[@odragz8118]

@@blazexiytb I know I'm late, but yes. You need to break in a new engine. First 500 miles usually. Look it up, but every motorbike & new engine has to do it. Even if it's just been sat for a few months. You don't just get on it and max rev it. You need to let it run in slightly first, do an oil change (to remove gunk at the bottom from it sitting) and then you can ride like normal after a while.

[@speersyboy99]

Thanks for the video! Could the “average joe” do this? Or would it be better to have it done in a garage?

[@BaconMoto]

I'd say if you've ever had a dirtbike and did the maintenance yourself (timing, clutch, piston swap etc), go for it. But if you've never done anything on a bike regarding the engine, i'd recommend going to a friend that has the experience or a garage.

[@danwilliams2935]

Did you put it on the dyno with the dB killer? If you put the dB killer back in you will instantly get at least 0.5 extra HP due to back pressure but with your 180 kit I imagine you’d be looking more towards 1hp, these gains may sound pathetic but I imagine it might help abit if ur planning on going as fast as possible on these little machines (I know this is true on most WR’s as I’ve seen many dyno sheets using this method but every bike is different)

Thats great to hear 20hp tho is a good gain suppose thats down to how well its tuned yeah every engine is different definitely agreeable but should all be around the same being yamaha lol

[@bekeneel]

Cranckshaft is not same as camshaft? Cuz Malossi makes a camshaft too for this kit. I think that extra stress shouldn't be a problem, this kit has been installed many times on a WR so, but WR is already out of production for years and I don't like it very much cuz it's a heavy ass bike and it was really expensive too.

My WR125x has 31K km on it now always changed my oil and filters on time do you think that would matter if I upgraded to 180 with camshaft? also there is a giant price difference in the kit that you use and Malossi do you think it is the same quality or wil the one that you use last a bit shorter, because i think malossi is just overrated.

[@BaconMoto]

I chose for this one because it had good reviews and is way cheaper then the malossi kit and it had some good reviews to it. Also It's hard to say if your bike will or won't take the 180. Look around on what km's others changed the 125 to a 180. If some have changed it around 30k and still drive without any problems, why not? If not i would be careful installing it, without changing the bearings/ crank just to be safe.
