I used a set of calipers and the glixal cylinder measured 52.4mm. For the price it's done better than I expected. I think I was unlucky and got a bad cylinder head.
@@mrpartridge8765 ya but performance wise is there any difference between them I mean the longer the valves the more open they are and more air to exhaust I guess
@@Smodlee there is no difference in performance with the longer valves. They open and close the same amount with both sizes. The rocker arm assembly for 64mm valves will only work with those valves and vice versa. The only way to get more valve lift is a high lift cam like the a9. I hope this info was helpful.
Do you think the Glial 100cc head the valves springs are the same as a standard 50cc ones and can you break through the head where the valve springs bottom when porting as you can do with the 50cc 64mm ones thanks. Jeff in UK
I've pinched multiple sets of springs with my fingers and they all feel the same. I wouldn't do any porting under the valves with a 64mm valve head. As long as you widen the port and take some off the bottom there won't be any need to port under the valve.
@@mrpartridge8765 Thanks for that I put 150 cc springs on the 69mm heads so I will try a dummy fit and see how they fit. 150cc ones are stronger just got to run a feeler gauge through to make sure of no spring binding let you know. Jeff UK
The springs are the same as the 150cc the inlet valve is the same as the exhaust valve on the 150cc head porting head ok but valves leaking need a good cutting it's just time doing it.
The naraku is doing amazing. If you have the money and want peace of mind get the naraku. The glixal head seems good for the price but with the defect mine had I wouldn't use it. I think I just got unlucky and got a bad one.
@@mrpartridge8765 I heard it was risky using their performance variator so Im not surprised there was an issue with the top end kits I'm about to grab a naraku or taida cylinder head and body and a naraku cvt super trans kit for my ice bear mini max I'm topping out at 43 rn that's with a 50mm big bore kit a crappy stock 150 carb and a performance cam and different slider weights in the stock variator also just got a new performance header and slip on carbon fiber exhaust just haven't been able to test cuz of my battery and a bad kick start I'm sure I'll be close to my goal of 60mph after the kits and the nibbi 24mm pwk carb 😎
@@jrjr5683 I use the glixal variator with my cvt schwinn scooter project. I had some clean up to do with a Dremel but other than that it's been good. For the price I'm fine with doing a little work. It looks like a clone of the naraku variator same thing with the rear clutch assembly.
@@jrjr5683 with a stock 150cc carb my 90cc kit was doing 45 running lean. I'm still tuning but it's no longer lean with a 110 main and 38 pilot. I can't test right now because of the snow. I'll post a video of it when the weather is better.
@@mrpartridge8765 I absolutely hate these 24mm carbs on these motors hopefully a well tuned pwk will do the trick so I don't always have to carry a screwdriver for last minute adjustments lol do you ever plan on running any type of performance carb I was thinking of getting a pz to compare to the pwk. Also have you messed with your final drive gearing at all? I'm trying to decide what gearing to go with for higher top end while maintaining decent bottomed end toque on the bottom end but I'm looking to achieve the highest top end speed possible without robbing too much off the bottom. hoping the 52.4mm cylinder will give a decent bump in power do you have any tips on crank upgrades And are u running any cvt upgrades?
does anyone know if these glixal kits are available with a 10mm piston pen for peugoet?
Correct me if im wrong, but i believe naraku is the only 52.4mm available and the glixal is actually 52mm.

Is 52.4 compared to 52mm actaully a big bore
@@chancesmall7026 they are both big bore .. 39mm is stock
@@scooterarmy damn I’m trying look around for my Tao db14 big bore size but the biggest I found is 52.4 and I believe it’s 52 already
52.4mm cylinder head sizes ?
What’s the difference between an 64mm vs the 69mm head? Does the 64mm have more compression or something
@@Smodlee it's just the length of the valves.

Did you modify your engine case to fit the 52.4mm big bore kit?
nope it was a direct bolt on. no modifications required.

@@jeffmee763 I got a naraku head that had leaking valves. I had to lap them and then they were fine.
How is it holding up now ? If you had to choose this one or the naraku 52.4mm kit that xost more what would u get ?
