piston

Is there an alternative to Yamaha OEM for piston rings. Any options more affordable?

Will need painting. Brake pads are included. I got them with a set of forks I bought but I have 6 piston calipers I will be using and don't need these. Whoever had them before had globs of black paint on them that I cleaned off. See pics. $20 plus shipping Thanks,

So, I got some 6-pot Sumitomos for a smokin' deal. Problem is, the P.O. Had them powdercoated blue which, by itself, isn't a problem. The problem is that he/she removed the old pistons by grabbing the outside with pliers. This wrecked them pretty good. Parts for these calipers are...

I have recently been restoring a 1990 Vmax 1200 and decided to replace the pistons from the original size to 0.25mm oversized. I also purchased the oversized rings with the aim to improve the overall performance back to ‘new’. As I went through the process of taking measurements I found the...

Just wondering what could of caused one of my pistons to blow. I have an 04 vmax with 6000 miles on it. I'm the second owner and it's being serviced. Then while riding with my friend and his gsxr600 we were racing and cruising around 100+mph then on the way home "pop" there goes one piston and...

Hi Guys, On Friday my rear brake quit working. pedal would bottom out but no braking. On the bottom of the master cylinder there was some brake fluid leaking, just enough to get on my finger when I wiped it. Reservoir still had plenty of fluid. I'm picking up the Master cylinder rebuild kit on...

Hi, I am replacing the stock brake and clutch master cylinders with Nissin remote resivours. I am getting 14mm for the brake (match the R1 calipers) but I do not know what size clutch diameter to get. Can anyone help please?

Hi, Is it expensive to get the 1200cc vmax engine converted to 1500cc? Or basically a just a change of pistons? Does 1500 pistons fit the stock cylinders? Is there anything else to consider if your thinking about converting 1200cc to 1500cc? Thanks!

:oops: I was installing my new brake pads and taking the opportunity to can-o-air out all the brake dust and what not while I was at it. On the front left brake I noticed one piston was a lot more recessed than the other 3, and grabbed a 1x4 to slide into the middle to be sure the pistons...

Here we go again.... there is a wiseco +3mm big bore kit with a 10.5 compression that will yield a 1394 cc. Has anyone done it? what do you people think about it if I am going to use an older Royal star Block with Vmax heads. Any ideas? shave the block? shave the heads? nothing radical, but I...

I have removed and cleaned front brake caliper pistons because of pads dragging a bit on rotors. I still have one caliper that drags more than I would like it to. I used brake fluid as lubricant to reinstall pistons, I am wandering if I use some silicone gel type lubricant on this one piston...

How? Stretch it? Also that snap ring was a BITCH to get out! And I sprayed some WD-40 in there before I read to never never never use petroleum based stuff in there. I didn't get any on the new parts, can I just clean the thing out really good with brake cleaner?

O.K., it's time to consult the experts! I'm at the stage of my build where I need to check valve to piston clearance and I'm wonder what is the best method? Im running MTC 78mm, 13:1 pistons and Web cams grind#227-0.383 lift, [email protected] duration, 276 advertised duration so I want to make sure...

Looking for some input guys......just bought my first Max, a 94 with 35,000 miles. First thing I did was check compression and had apx 180-185 on all four cylinders. :eusa_dance: So I proceeded to fix her up. Pics are posted in the User Mods section under My New Max. Anyway, the other day I...

I was checking out a piston the other day and I noticed wear marks on either side of it as seen in the pictures... ...is this normal or dangerously expensive??? I haven't checked out the other pistons yet...they might have it too :(

I have a 92 Vmax with 4 piston shimoto brake calipers on front, I need to rebuild the left caliper, does anyone know where to find a rebuild kit for it? Any help would be greatly appreciated. Thanks, Ed

Here you go for you guys wondering. Advertised compression is the same for the vmax as it is for the first gen ventures. Sean

I am going to be getting my cylinder bored out to fit stock venture pistons in my bike and was wondering if anyone knew what the piston to cylinder space was supposed to be. Found a shop that will bore and deck my case for $300 , not bad I think. They use a cool CNC machine to do most of their...
