Congrats on being the only one of the 1000s of videos that understands it's the LINE underneath the 'T' that indicates TDC not the letter itself. Same with the 'F' for ignition timing, it's the line adjacent not the letter itself. Please tell all the other wannabe 'experts'. BTW that might well be my mum on that Lambretta. If that's the case it could be me in the sidecar. Thank you and goodnight.

[@kachiskid]

I greatly appreciate the compliment! You have a great night!

[@kricklasalty1464]

Yet he only showed the “T” fer 1/30 of a second, so the info was near useless!

[@carlkennedy2499]

You definitely did the tipping haha😂

[@kachiskid]

Yes sir.

[@lioguada3264]

Hello, your video is very good, thanks for sharing it, I have a gy6 with a high-flow filter and a little richer fuel, what size do you recommend for my valves? My idea was .004 intake and .006 exhaust. thank you

[@kachiskid]

.004 intake and .006 exhaust is perfect. No problem.

[@thelagmeister]

I believe I had the wrong valve clearance on my first kit and that's why it failed. So. I got me a 2017 tao tao 150 today. It looks oddly familiar...

[@kachiskid]

WHAT! Send pictures...now!

[@thelagmeister]

@@kachiskid I'll try to send some tomorrow and a pic of that thing I wanted to send you. You're gonna like it.

[@calvinmorris4188]

Ive seen so many different clearances on KZbin lol ive seen .004 for both and ive seen .004 for intake and .005 for exhaust and now .007 😂 what is right and what is wrong? Gopower sports says .004 on both somebody has to be wrong here.

[@kachiskid]

Who I learned from, taught me should be .002 between the two. .004-.006 is common. My engine ,and what I'm doing, isn't common.

[@daveb1803]

you abslolutly want an oil cooler thats the single best thing you can add to prolong the life of your motor. dont mess around with a small oil cooler get a big one those motors run hot to hot in my opinion. my runs 200 on the hottest day wide open throttle for 20 to 30 miles at a time.i have a 24 row cooler

[@kachiskid]

Send me a link to your cooler, I will take a look. My bike is not an everyday rider.

[@RubenMartinez-d9z]

Why didn’t I watch this video first 🤦🏽‍♂️

[@kachiskid]

So many options out there.

[@sandeepram8429]

Ciao, il mio scooter faceva rumore, ho fatto il gioco valvole ed era risolto, ma dopo due giorni è di nuovo come prima. Quali potrebbero essere le cause e come potrei risolvere?

[@kachiskid]

Ehi fratello, non sono sicuro che avresti bisogno di fare di nuovo un'autorizzazione così presto. Se si muovono sostituirei i bilancieri ed eventualmente la culla. Cosa stai stringendo anche i dadi della culla dei bilancieri? Specifiche della coppia?

[@GY6-SCOOTERS]

Your new engine for hope looks sweet bro and powerful good job cant wait till next video to see hope start back up and head down the road again ...👍

[@kachiskid]

Man, I'm getting excited now! I can't wait until I hear, smell, and feel this engine. Right now I don't know what to expect, but I seriously doubt I will be disappointed.

[@WeresheepLightbringer]

.005 - .007 is clanky on my GY6 125 that's why I always set .002-.003 as instructed by local motovloggers but I feel that it's too small. The also say that the factory tuning is .004-.007 which I'm finding very hard to believe since it's just too clanky when I go past .005. I'm tempted to try .003-.004 and see how it works. Also I always need to tune my air fuel mixture again every time I adjust valve latch.

[@kachiskid]

.003 -.004 is where it should feel pretty good.

[@pattayakamagra8325]

IN 0.8mm to 0.10mm EX 0.15mm to 0.20mm . This engine is build on metric system so use Metric measurement instead of Imperial . . more easy :)

[@WeresheepLightbringer]

​@@pattayakamagra8325 .8 mm is too huge, and it's bigger than .10 mm, maybe you're referring to .08 mm perhaps?, if you converted that to inches that would be .003 - .004 inches which I mentioned above. It's been doing fine ever since. Never needed another adjustment ever since. You EX recommendation though .15-mm.2 mm (.006-.007) is where I get the clanking sound. The widest I can set mine is only .005 in (.127mm)

[@andyproctor3588]

Starting to see where this is going looking very cool✌

[@kachiskid]

Yeah it seems to be coming together nicely, hopefully no trouble on the the horizon.

[@austinwright5307]

I bought a new scooter brand new from a dealership and my first ride I took it out and it ran for about 30 mins and it stopped when i was riding in and now it won’t start up

[@B2FixRepair]

You have any contact for some question? I have a maddog icebear 1 generation. Dont start, just I can hear the sound of the starter spining, when I remove the pipeline of the gas from the carburator, and try some few times to start, so than start, and I put the pipeline again and run, after some hours of run, start normally, but when I let the bike overnight (long time off) , the problem back. I already changes the spark, the starter, the clutch and still the same problem, tomorrow I will change the carburator

[@kachiskid]

Yes, [e-mail]. So the engine is turning over and starting? What pipeline are you speaking about? Can you send me a video of your problem?

[@edgufler1122]

Very good video on how to adjust the valves. I had to do mine at the end of September and it was no fun at all. I didn't have that specialty tool and it took me several tries to get the gap right. Thank you for this video.

[@kachiskid]

Thanks bro. I would have done it sooner but the market was flooded.

[@adrianscoggin7212]

​@@kachiskid got a standard 150cc and was told to do .004 on intake and exhaust valves.

[@kachiskid]

@@adrianscoggin7212 Wait? Make no separation between the 2, even by .001? First time I have ever heard that. I obviously learned at a different school. I think your bike should tell you, but try the .004 and keep me updated.

[@adrianscoggin7212]

@@kachiskid Yeah I was told by a dude who's been doing it for years that it was .004 for both intake and exhaust valves. I thought the same thing too that it was .004 on intake and .005 on exhaust. Apparently another dude from the KZbin channel rolling wrench said the same thing but that either .005 on both or .004 is fine.

Kachi's Kid I have a 2016 Sym HD 200 (171cc) with 19k miles. Have had the valves inspected once at 7k miles and they were ok. Now at 19k miles and I'm gonna do it myself because it looks just too easy. Question: Now at 19k miles of mellow easy use, should I still use the .005 intake and your suggested .007 exhaust numbers? Thanks Again Dean Seattle ,

[@kachiskid]

No problem. Yes, on your 171cc it would be fine at .005 -.007. Yes sir, adjusting your valves is very easy, just make sure that piston is at the top of the engine.

how about for gy6 scooter valve 23 28 with 7.0 cams 160 cc what should be my valve clearance sir should i go with 6.5 camms regrind instead for top speed? and acceleration

[@kachiskid]

Young man, I don't know everything... but i would set yours at 0.004/0.006 and see if there is any chatter. I haven't done a lot with cams, I did like my A14 for very quick acceleration, but fell off at the top end. I have an A11 (I think) in the 180cc engine now, and just haven't run it enough. Next summer throwing in my Taida cam, so I will see.

Hi, my scooter was making noise, I did the valve clearance and it was solved, but after two days it's like before again. What could be the causes and how could I resolve it?

[@kachiskid]

Hey bro, not sure that you would need to do a clearance so soon again. If they are moving, I would replace the rocker arms and possibly the cradle. What are you tigtening the rocker cradle nuts too? Torque specs?

@Kachi's Kid....when I do this, is there a gasket and should I replace it..? First opening her up, so I'd like to be prepared. She's a 2006, low original miles under 3000...Also, do you know factory valve size..? I may upgrade the valve, seats, & springs(if needed/I want to, lol) but I'm not big boring, just the stuff I mentioned in other post, so I dont wanna go crazy

[@kachiskid]

Yeah, you could check on the health of your gasket. If it is super flat you might want to replace. The valve sizes should be on your scooter.

If you are absolutely certain that you are getting no air leaks, I really would swap the carb. just to see if it will make a difference. What kind of filtering system is on this ATV? I imagine it is ridden in dirty or sandy conditions?
