lambretta cooling v anemometer

[@SCTALLN]

Thanks for these videos, it's eye opening stuff that small changes make quite a big difference, got to love science.

[@davidblagden7894]

Been waiting eagerly for another one of your vids & you haven't disappointed Steve 👍🏼 very informative & needs more testing as you said, short fin, long fin, lightened flywheel etc. Quite a significant difference from standard to your design so I know what I'll be doing over winter 😀 Cheers Ste & keep up the mint vids 👌👍🏼

[@TheSteelweasel]

yep now people will want to know how there set up works .... i want to test casa varitronic and af . there will be some sick puppies out there , maybe we can do a sweep stake ...... all bets on ha ha

[@Apitajam]

Since I saw your first videos about cooling, I remove the central part of the cover and the difference of temperature is huge in all my lambrettas.

[@CarlEves]

Love these videos. At last something I can do with my vast experience and mechanical skills. Cut the centre out of my flywheel cover 🤣. That’s my next project. Thanks for doing all the legwork and experimentation.

[@PaulSmith-ff4kf]

Very interesting Steve, can't wait for results on more tests, good work 👍😁

[@gordonduffy4016]

Thankfully I purchased the cowling set as I now definitely know that my scooter is going too be running alot cooler cheers Steve

[@midge225]

Nice one steve , glad i bought one of your covers now mate , proves your covers do the trick and help cool the motors better 👍🛵

[@TheSteelweasel]

gonna make more tests mate lets see how good i can get them test mod test mod ,,,,,,😜

Would you say it’s worth cutting out the webbing on a standard flywheel cover to let more airflow?

[@TheSteelweasel]

Yes absolutely

[@jasongreen3087]

Great vid as always would you still run the dust cap though have you tested this id be very interested with the results.

[@TheSteelweasel]

will be doing more tests

[@georgeyboyhowe1685]

nice one steve would a standard shroud with the centre removed work cheers atb

[@TheSteelweasel]

been cutting them out for years mate , yes it helps

[@Best2Strokes]

Very nice bro 😀👍

Flywheel from czech republic? what kind of electronic ignition are you using in that lambretta?

[@TheSteelweasel]

vape

[@adrianobonaldo8941]

@@TheSteelweasel oh thank's but is available in uk? If Yes could you please give me the indications of the website. Anyway how you feel with this electronics ignition?

[@TheSteelweasel]

@@adrianobonaldo8941 its the best ive had very good quality . two versions , static or race with advance . im using race version . you can get from SIP or scooter center

[@adrianobonaldo8941]

@@TheSteelweasel thank's a lot. In the past I had modified by home work the old stator with original spark ignition innocenti 6 volts now obsolete, using instead of it the bobin and pick up of electronics px. For flywheel, my old friend by machine work has modified the magnets making a cast in protuberance for pick up. Was working it was an esperiment but well done anyway.

[@philmarsh6655]

Top work Steve, looking forward to getting my set fitted when I eventually get back to the UK. All that extra cooling and a free Thai Duck Curry thrown in too? And all I had to do was allow your mad arsed dog to slobber all over me 👍🤣😎

[@TheSteelweasel]

any time mate your welcome

[@raphael3891]

I have the bgm electronic kit on mine too and i purchased the casa performance cooler kit which meant i had to machine the fins slightly of the bgm to fit the casing i wonder if it affects the cooling as i reduced the size of the fins

[@TheSteelweasel]

Yes I would think it will reduce flow ? Also clearance between fan and cover is very important it should be around 1 to 2 mm . Dont have a casa cooler to test unfortunately

[@ericwalker2172]

Hi Steve yet another good vid does this mean if you put a good kit on your scoot with all the bits to raise the performance in Britain we also have to sort the flywheel cowling out or we might seize the engine in the summer 🤔🤔🤔

[@TheSteelweasel]

summer or winter lambretta has the cooling of a BBQ mate the barrel and head is calculated for a 125 cc scooter in the 1940 s what do you think ?

[@ericwalker2172]

Thanks for the advice Steve👍👍

[@CarlEves]

I just looked at mine. Mines a Spanish cover without all the rings. I expect they found what you did and improved the design a bit. Thoughts.

[@TheSteelweasel]

best remove center and dome dust cover .

[@CarlEves]

@@TheSteelweasel yes I’m going to mate. Surprised about the dust cover. I would of thought it would help channel the air in. I know it doesn’t otherwise you wouldn’t say take it off. 👍🏻

[@TheSteelweasel]

@@CarlEves thats not what i said ? dust cover stays on ...........

[@TheSteelweasel]

Remover center of cowling not dust cover ... dust cover to be domed? Wait till next video if you dont understand bro

[@CarlEves]

@@TheSteelweasel got it. However I will wait for next video. They are my must watches. 👊🏻

[@graemelake8419]

But how much flow do you actually need?

[@TheSteelweasel]

more air flow removes more energy , unfortunately we dont have the correct surface area so we compensate with as much air as possible ...... more power = more heat ( energy) so as you can see its not possible to quote the amount needed as we all have different engines there for different heat range ? the original lambretta li 150 was 6.6 bhp and designed as a commuter , no motorways or fast roads . the fan and fin area was designed for this use ,we now sit on motorways with 25bhp + hope that explains why im doing this work . sorry i cant help you with the exact flow for your engine 👍

[@triplefanatic]

In the interests of good Science pls post a comparison of standard flywheel cowl with the central (grille) section removed - would make for a much more meaningful comparison as that grille restricts flow significantly.

[@TheSteelweasel]

thats in the previous i think ?

[@TheSteelweasel]

standards li set up is 4.4 ms with center out is 4.9 ms and if you dume the dust cover 6.1 ms
