Means u have a 240cc big bore kit on it maybe even turbo charged.. j/K dude idk. Did I gas u up?? LOL
how did your DIY port job turn out ? lets see some pics of the finished product.
mabey its just a typo.... dont sweat it man, its not special, its not different. if its on a blaster then its just a plain ole blaster cylinder. if u are super worried about it post up some pics
I dont see how yamaha could mistake y-1 for y-2 ? I have another blaster that i bought on that same day and it says y-1 .....
Lol .... If it had a big bore kit or turbo in it i would hear a big difference in noise and have much more power , I have 2 blasters bought on the same day ( brand new and stock ) and one says y-1 and the other y-2 ? There on youtube btw ..... just type in Yfsblasterman i have a few vids up there
Shee Carbs are Blaster carbs! The left carb can be used on a blaster if you block off the cross over port but the right carb cannot! There great for internal parts the body is different and has no choke!
if i got this done at my mechanics shop how much does somebody think this will run me to get it dun?
had a go at my 240 cylinder, not perfect but alot smoother than before still waiting for my vitos piston, been 3 weeks now!
few marks in the second pic but didnt want to go much deeper as i was flush with the gasket at this point

sweet videos, need to find a dremel and try my hand at this. this would be find to do with stock everything else right?
I did and the difference was HUGE! I raised the exhaust slightly more than 1mm and widened it just a hare almost accidentally at the bore keeping things smooth. Matched the exhaust to the gasket, cleaned up the transfers, opened up the boost port and removed a LOT of metal from that whole area. Also, I cut the piston a bit to better match. Oh, I also shaved my head down a TON, gave it a nice dome and squish band. However, it was the toomey racing pipe that made the biggest difference I think
How much is the cutting wheel and carbon wheel. I work a lot with fab. Granite it should be easy for me
It most likely just identifies a newer or old casting and/or which foundry poured the cylinder. There is a similar thing like this with banshee heads.....early banshee heads say something like "GUY-1" and them were on like the first 2 yrs or so and then the casting number changed to "GUY-2". The early heads I know have approx 2cc more volume then the newer ones. I doubt there are any port changes or anything major on your "Y1" and "Y2" blaster cylinders. Basically don't sweat it.
I have a mikuni tm35mm carb for sale if interested. Everything works and there is nothing wrong w/it. Pm me w/an offer.

I did something very similar with the 1st jug I ported, raised windows, raised exhaust, cleaned transfer ports, cleaned up piston windows & slightly enlarged, also with a Toomey exhaust. Lil engine runs very impressive, working on the 2nd jug for it now, trying to learn more & further refine what I did the 1st time.
