Did you modify said exhaust?

Hello . . . For what reason do you use the 20 hole atomiser please?

Was that Homer Simposon?

Good to know

Nice one

Nice movie Steve ! Always a pleasure to look at this.

Typing this as I watch.... It's hot here, too. Don't forget to hydrate! I'm going to try to go the garage early in the morning and leave early. I've got to strip the gearbox, I think my rear hub seal is blown. Hey, doesn't the clutch nut take a tabbed washer underneath? Or did I miss it? Geez, I never considered hot gearbox expansion. Thanks for doing this because I'm lax on checking stuff. Hahahahaha, Tino called!🤣🤣

Look like great covers. Do you sell them?

Hi steve great videos as always, am fitting an external condenser and was wondering were is the coolest place to put it under the panels on the lambretta if there is such a thing. 😆

Brilliant Steve

34c never mind Steve sure you'd prefer that than the f**king crap summer we're having in Yorkshire this year .

Ça tourne

Magnificent job done yet again Steve. Safety comes first, and great advice mate. Hope you enjoyed a nice cool one after that 👍🍺

Thanks Steve for taking us through the safety checks.

You'll need another locking tool as the vape tool doesn't fit Mmw big fin

They should Pay you 🎉

You are making avertaising to jack Jones 😅

Interesting as always Steve. I always open up the cowling aperture around the head as you mentioned here, it seemed an obvious thing to do! However, I do have a cooling question for you. I'm currently kitting an Italian GP with an RT195 (piston ported). I'd like to keep it's original cylinder head cowl which has the internal deflector / baffle (which seems to channel more air towards the exhaust manifold). So, my question is . . . do I leave the deflector / baffle in place or remove it? Your thoughts would be most welcome 8-).

"Black sabbeth " you mean ride like youv'e got the wind 😂💨

What’s the name of those temp guages and where to get ? Cheers

Nice video Steve !

Enjoyed that Steve but just a thought. Crankcase has oil splashing round and has a vent albeit small to dissipate pressure and therefore heat. Stator on the other side has neither and probably cant get to the stated “140°C so chances are in England shouldn’t be an issue. That said 100% agree with the cylinder head cooling. Think I’m gonna drill a few holes as you said but it’ll be after 1000 mile run to Aviemore and back starting on Thursday 😉

If your a real mechanical engineer then a Auto mechanic shit makes sense.

You little teaserl

While you do make valid commits . The big head when used with the Avanti barell is good at cooling the engine. As for the "fancy brackets for Cdi mounting mine are on lugs specially to allow air to circulate both sides to aid cooling andadeon alloy to act as a heat sink

What a great video to get you thinking, makes total sense, have cut my flywheel covers out previously but the holes in the cowling are gonna be next, keep em coming Steve , great work.

Those Scootronics stators are junk just cheap components on a fancy backplate be lucky if they last 1000 miles .

Avanti? 🇦🇺

Have put some of your tips into the race scoot 😉

Great video Stephen! I Never even thought about that air flow OVER the head!! My LI 150 used to heat seize when I was 16 (53 years ago) - I’m now thinking it was either bad cooling or the little hole was blocked in the petrol cap!! Fuel starvation? Alas, I will never know.

Fascinating explination on the theory of Air flow & over heating Steve, brilliant. Now enjoy a nice cold one 🍺👍

Had air cooled 2 stroke quit, only to start later when cooled a bit. Fuel vapor lock or electrics? Excess heat anyway

A IR temp gun could be used to measure surface temp, instead, right? On my current engine in my blue and orange GP225 TS1, cylinder head temperature on the motorway after four hours of riding on tour with short breaks and only one long lunch break, measured from the lower right cylinder stud, went up to 168 C on the day I holed the piston when I ran the tank dry of fuel! My next TS1 build for my other scooter is using a big, square MB cylinder head with a scoop to direct air to it, with the shroud cut away and directing air only around the cylinder. Would that work? I think the climate here in LA is about the same as you've got in Spain which is why I prefer to ride more in the Winter and Spring. Many edits to write this fully. Btw, I've bought a thermal barrier (plumbers' welding blanket) to protect the carb from heat. What's the best way to secure it?

SOMEONE UNSUBSCRIBED LOL IT MUST HAVE HIT THE RIGHT SPOT . 🤣🤣🤣🤣🤣🤣🤣🤣

Best episode of the year. Been looking into this for last two weeks. I cut the flywheel cowling centre out and i am going to cut the left hand side of the head cowl as you have described. A article has a stainless steel plate over the right hand side of the head to stop the air out of the exhaust manifold, it said the fuel kept that side of the head cool . I am going to put a shroud behind the manifold and tap out my flywheel dust cover to make it more pointy. What gasket sealant would you recommend?

Interesting video Steve, Honda had a issue with there V twins and fours due to the body work and location of electrics i.e. regulators even causing fires.

No mumbo jumbo. Facts that make sense. Keep on keepin' on!

I've always cut the centre of the flywheel cowling out since the mid eighties,and I've done the mod to the head cowling(holes along the cylinder head part)a few years ago and no problem as yet even on hot summer days on the M4.i found the coil part interesting and hadn't thought of that.intresting that the mammoth head was thought of by a racer,but you'd of thought they would of known better about cooling🤔nice video Steve very interesting indeed.👍

Top Work again , simple and straight forward, how has no one redone the head cowling ,everything makes complete sense

See it all the time from so called welders 😂there all over you tube

So bad , hope you were able to fix it properly. 😊

Looks like a piss poor job, bloody cowboys

Wow. We have come a bit further from the under kick start Frescos from the 80's. My hat goes off! 🎉🎉🎉

Hi steve, are these on the market yet, and wot exhausts are they for ,cheers

Hi Steve, Great channel keep it going. Can you explain how an engine runs in reverse? i rebuild an engine with a 195 kit (BGM) Set the timing to 19• BTDC with a 360° disc. i decided to have it checked by a friend with a buzz wangle and strobe light and it was out. On a few occasions the bike has reversed in first gear, please can you explain? Help!

Hi steve ,is there more info or a longer video, cheers

😮😮😮😮😮

Steve. What’s the exhaust on the RA 48secs in. Not seen one of those before

Where is that? Was wondering if it’s Majorca ?

Extraordinary
