As long as it's copper gasket spray I guess from a decent company, you should be good.

Thanks for the links. Can't open the link for the Facebook..

Must use copper gasket spray for the head gasket. That will stop and seal the head properly. If you're going in there constantly adjusting the gaskets because of the leaks, you got nothing to loose then to separate the gaskets and use single layer gasket, with copper spray on on sides of the gasket,...

My lithium shorai battery is still good at nearly 12 years after the purchase. The damage thing just doesn't want to die...

I'd be super keen to go 4 valve. My only draw back was 2 valves, I got as much as I could out of two valves, there is no more power. 4 valves would open it right up.

It will run rich on low throttle, half to 3/4 throttle should be around 14.7 and full throttle is at 13.2afr.

But that's on mine with takegawa fuel corrector.
Im not sure regarding your question on self correction. You need an afr meter and just watch what's it doing...

Thanks Hobbit112, that's a starting point...

no……………….. to me, they were worn out after using them for 15,000 km. i had to replace the sliders as the revs were getting higher than usual. Probably your belt was worn out, got skinnier hence your increased revs and would have less top speed. 15000 on a belt is great but performance suffers. Slid...

A question on throttle body and manifold size for the Yumanishi 150cc head. Which size would be best? I am seeing 30mm, 32mm, and 34mm throttle bodies and corresponding manifolds. I know the intake valve is 29mm and I do know that going too large can be a detriment. Insites? Suggestions? I haven't ...

Pcxdemon, you ever Dyno your set up? I did while ago. It had 31mm throttle body and ok transmition set up. Then again, had no base, stock pcx to test and compare first so I guess dyno calibration may have been incorrect. Anyway, it put out 15 something HP at the wheel. Once I installed 34mm Forza t...

Hello . why don't they mount the yuminashi turbine with more cooling blades? until seeing me it has worked Blades are orientated counter to stock. Orginal fan pulls air in thru the radiator, what is that one going to do? I tried that one on mine few years back, and my temperature gauge went up...so...

Radiator cap 1.6 bar. Injector 170 cc see Throttle Body 31mm. Collector, air filter and its pipe included. Camshaft and rocker arms with double springs. FI CON2 Takekawa (previously Takekawa 170cc kit, now Yuminashi 164cc). Candle NGK9. Yuminashi CVT and long gear 15/45. I decided to tighten the cy...

Do you have a Big bore? Thats almost half the time than the fastest 0-40 on here.

Yes, 170cc. Yuminashi chainsaw tread, look it up.

Installed Yuminashi full set of 164cc. I put a long gear 15/45. Started driving. In a few days I drove 180 km. Then the scooter started overheating. The red light came on. I pumped the water system many times, the result is deplorable. The steam is collected, the pressure in the radiator, the liqui...

Pm me and I'll give you a full detail of my transmition parts. I think as far as transmition is concerned, Iv egot it dialed in to a tee..

8 years on shorai lithium battery. Never had to charge it. It just lasts forever it seems. Was exy to buy like 200 vs 80-100 for original type but after all these years it's still going. I'm sure it paid it self off many times now.

So true conelite..
I guess, its hard economic times. People don't have spare cash hence no interest at modding.

Thanks white noise,
There is little interest, so no bother..

why have you put the same post on just about every section of the forum ????????? Hi Yorkie, Some people only stick to their sections for their bike. So, to reach all Honda scooter lovers more effectively that might be interested in this exercise it got posted in every bike section. Unfortunately, ...

0-40mph is pretty useless , there is not much data on that to compare with. Most people test and discuss 0-100kph or 0-60mph acceleration stats and figures. So let us know what is your best figures for that, flat road, no wind behind, and include your weight. From what I see on internet stock PCX h...
