Are the power valves the same on the 125/144?

XR in the background. I'd recognize that heat shield anywhere 😁

Fabuloso in water

What’s your opinion on maxima 927? I’ve been running it In my bikes and skis. Don’t seem to see much build up. And I know castor protects very well

@highlandcycles 2 года назад

I’ve never used it but I know it’s good.

@benselby6171 2 года назад

@@highlandcycles I’ve heard it can cause build up. I would think as long as the jetting is good it should be fine?

@bryancalvillo4169 Год назад

Do the bolts at 8:24 hold down the round part on powervalve tightly? Mine have a bit of play and I wonder if I need to shorten my bolts so it holds down snug.

@highlandcycles Год назад

It should be snug

@bryancalvillo4169 Год назад

@@highlandcycles thanks brotha it didn't seem right that it had a .5mm gap. I think I'll shave the bolts down a bit for a tight fit.

@joejones1330 3 года назад

What size flex hone do you use for your cylinders?

@highlandcycles 3 года назад

I honestly don’t know the size off the top of my head. I have a big selection and I just grab the one I need.

@joejones1330 3 года назад

@@highlandcycles I just looked at that video about the top end rebuild it’s on the two stroke for some reason I thought it was on a 250 four stroke . I think I’m going to go with the 3 1/4 inch for my 78 mm piston.

i have a yz 144 and need a head gasket do you know where i can find one ? or if the oem one will fit?

@highlandcycles 2 года назад

I would try Athena

Still wondering how to rebuild the xr 100

@highlandcycles 3 года назад

Me too. Actually, I found a part we need. Little gasket so no biggie but have to order it

The banshee does just fine without power valves..

@highlandcycles 2 года назад

It’s a twin and not built for what a dirt bike does

@geopioneergsxr5357 2 года назад

@@highlandcycles I'm aware of both and have both and have rebuilt both numerous times. I just know that the Banshee basically proves that power valves aren't that necessary for a powerful 2 stroke engine. Although, on the other hand, a 250cc 2 stroke dirtbike has way more hp than the 350 Banshee... So nvm..🤣

@highlandcycles 2 года назад

@@geopioneergsxr5357 I wasn’t meaning to be a jerk. Some people just don’t know what a power valve does. It definitely doesn’t make more power. Just a broader power band so they are easier to ride.

@msoto951 5 месяцев назад

Great video👍🏻 Question. I have a 2004 Yamaha yz125 I was told the are a few different size of pistons those bikes take how do you tell which one your bike takes? This would make a great video by the way..

@highlandcycles 5 месяцев назад

Originally its stamped on the cylinder. A B C or D. If that is worn off you have to measure but the reality is that the difference in size is almost negligible. I almost always use a B piston.

@msoto951 5 месяцев назад

@@highlandcycles thanks for the response. I measured the cylinder last night and mine is a 53.4 mm which is an A so that what I just ordered right before I read this. But I will keep it in mind the next time redo the top end
