The Honda PCX / Forza / ADV150 / SH Forums

SH300 is awesome scoot. Handles like a motorbike, goes like one too straight out of the box.

Going back to exhaust, Takegawa makes nice pipes that deff do give better performance and almost stock exhaust noise. They're Mid priced too comparing to lot of others on webike.

I've got koso water meter installed, it's good having it especially on a modded motor. Stock motor comes with a single layer headgasket but Takegawa has triple layer. That's ok on a 125 head by once you fit 150 head the comp drops even more to 10.5 I think. I prefer to be in mid 11's to low 12's com...

Thanks Gil, I've been itching to get back in to the engine and do some more modding, so this gave me a perfect excuse to strip it down.. :lol: I want to split the triple layer headgasket and just use a single piece to raise the compression a bit. I've done it once before so I know it works and it's ...

I've ordered new pump and a o ring of partzilla last night. I'd hate to get that leak again if I'm far from home and can't get help out there. Should be fairly easy job to replace it (I hope!)

Sorry i got busy afterwards, I forgot. But thanks to other forum member it's on there now..

Found the leak ! Crack on the nipple that connects to the fuel line . It's a new fuel pump job. I've posted the video of it on to YouTube

Could be the fuel vent line leading to the charcoal canister. I would check that first. I only have leaks when I overfill the tank, lol. Gil Hi Gil, leak is coming from the top of the fuel pump where it's inserted in to the fuel tank, around its base. Maybe a main seal is shafted or the bracket hol...

Hey all, has anyone here had trouble with fuel leak from the top of the fuel tank when motor is running?! Mine just sprung a leak...

Plenty YouTube vids there on this topic.

:D I'm way past 13g roller and I'm sure I have vario options in stock to do what I need. I think perhaps going 140 and 120 may be too large considering loss of top end, perhaps slower acelaration too? I'd be inclined to try 120 rear and 100? at the front. Has anyone tried 120 rear? Mirrors are cool,...

How have you performance been affected by those large tires? Lost any acelaration? Gain much top speed? It's my exhaust that contacts the ground first with these shit stock shockies around the twisties so that's my primary reason for extra height. I'm going to Thailand tomorrow for a holiday so I'll...

Hey, let's revisit this topic. I'm in need to replace the tires again. I'll probably look at michelins. Has anyone that has upgraded to larger tires found any negative effects from upsizing? I'd like to gear mine up as my power to trans ratio is much too short now but I also want to gain some overal...

Thats also takegawas specified valve clearance with their cam.

Magic rpm number for cvt set up is 8000rpm. Best accelaration, unaffected top speed. On 125 that's 10g weights. What weight will do that on 150? Unless someone uses a tachometer we don't know if the weight is 12g or 13g...

10g is best balance for highest acelaration and unpeded top speed runs on 125cc model.

Hello, I'm new here and I would like you to tell me if someone has tried a few dr.pulley 13gr on the 125cc engine, really this weight is the one you have to have? I have seen a video on the internet where the bike on the easel takes 4km / h more. Forgive but I'm using google translate, I do not get...

Or just tighten up this one as obviously hasn't been tightened up properly.

They adjust fuel using dealer's scanner tool, Yamaha allows to adjust fueling +-15% as I know, so no any fuel piggyback ecu is needed. I asked one ebay bbk seller why you don't supply any fuel controller with the Yamaha big bore kit. He told me to use Yamaha diagnostic tool also. But, +15% is still...

Yamaha BWS 155cc dyno run!!
