I like this one. You guys do a great job of explaining how these parts go together and work.

[@joegriego9805]

Thank you so much for this amazing video. I installed the v4 head and cylinder kit, along with the Forcemaster 2, after ordering from Scooterwest. It turned out great, and your video made it super easy to install. It's the little tips and tricks (how to remove/install the rubber stud o-rings, how to remove/install the piston clips and rings, how to properly torque, how to disassemble/reassemble the auto-decompression system) that made this completely worthwhile. You guys are great, and thank you for this video!

How do you tell ifbthe piston rings are seated correctly?

Andy Roberts please somebody help me. Is the Polini camshaft compatible as a malossi kit?

[@AnnDee4444]

@@MrLaranjeira88 I have read that some people have used the Polini camshaft with the Malossi kit, although I am unsure if they also modified their piston for clearance. See: kzbin.info/www/bejne/h2HXd5enasydnZY & modernvespa.com/forum/post2288968?highlight=#2288968

[@ginoasci2876]

i bought a Yamaha Warrior 350cc ATV and rebuilt the whole thing, engine included. yes it was fun to ride, but had more fun rebuilding. the knocking that came from the crankshaft eventually went away, and that as a miracle because it was pretty loud, but never replaced the crankshaft, just the sleeves. it was as quiet as a church mouse after a short time of riding. if i’m ever out in california again, i’ll make sure to drop in and say hello. who knows, maybe i’ll buy a scooter. nice job guys

[@bhasselgren]

Very nice video - I got stuck watching this. Fun just to see how the cylinder & co. looks taken apart.

[@BBGBITW]

very informative video, I used for my Malossi cylinder kit install, many thanks!

[@modmel57]

I bought a new Vespa GTS 300 Super in November 22. It was delivered with only the test drive mileage on 8 mile . It was garaged over the winter months ( UK) kept on battery tender . Upon starting it a few week ago it just didn’t sound right , a clattering noise from the top end . I made a video of the problem and sent to my dealer who by the way is top notch having bought scooters from them over twenty year . After a week I was informed that the problem was the decompressor , a part of it had broken off and damaged the valves. So it needs a new top end apparently no other damage . As yet I’m still waiting for it to be repaired . The dealer informed me that in over seventeen year selling the GTS , they had never encountered this problem before . Just shows first time for everything, although I wasn’t expecting this on a brand new scooter .

[@andreszanotti12]

Really very didactic and precise, I installed the cylinder, cylinder head and force master Malossi and the truth is that the power is magnificent for a vespa 300

[@VespaMotorsport]

Awesome job! Glad you tackled the install with success. Thanks foe the support!

[@Gasrullen]

I have been tuning bikes, mostly extreme tuning on small twostroke scooters and some 4strokes since i was a kid, And i loved this video, can't belive it was almost 2 hours! Subscribed.

And i wonder what another exhaust and giving it a little more air to breathe would do+this kit, Hopefully i'll find one to do it on.

Hi Robot, great job with all the vídeos. I have a question for you. I have a 2014 european gts300ie with around 20 thousand miles. Lately I have problems to start it. As you know you can not turn the throttle while starting the bike since it will actually not start. Well the thing is that if i do the normal starting procedure (brake lever and start/ignition button) the bike will not start, actually there is not reaction/noise at all. After playing a bit with the throttle it will actually eventually start. Not sure if it really has anything to do with the problem. Any thoughts on the problem. Thank you in advace for your help. Best regards from the other part of the pond.....

I use the standard head so do I use the black thicker gasket if I just place the default head back on?

What size is the temperature coolant sensor bolt Also I have a GTS 300 engine 2012 fuel injected I wanted to use with new led display clocks from 2015 however the temperature sensor has 4 pins and my loom shows on two connection wires which I have conveyed to your standard aide to side 2 pin sensor my question is will it still work as on my display the temp gauge is same as immobilizer light and not sure why only works manually from relay to start instead of from the button but obvcourse I might have immobilizer chip issue but would a disconnected temp sensor stop the bike from turning over by the button as nothing happens and button tested and replaced

[@romansandner1596]

Hi, great Video series! I have done a complete engine overhall on my 125 gt l (2003) according to your tutorials. This was my first experience on a scooter and thanks to your instructioncs nearly everything went fine so far. On my 218ccm malossi in combination with the V4 head I had no chance (really no chance) to get those O-rings in, which came with the malossi gasket set 1113960B. Is this normal? Since I have forgot the lower chain guard before fastening the head, I had to reopen it. I hope the gasket has survived.

same problem i did nt put them in and it doe nt lose any water and yes i used the gasket again no problem
