I had a similar problem with a Yamaha vxr. Would start and run great but then start bogging. I went through the carb and fuel system over and over. When I tested electrical the three coils at the...

The zxi is alive again!!! Just fired it up and she’s blowing smoke like she’s supposed to!! So here’s what happened: I spent a bunch of money gathering parts to build a 96/97 style motor to drop in...

I just solved a bogging issue on my vxr650. It was a bad ignition coil. I would however start with your fuel system, check hoses, tank vent, fuel filter and fuel selector. If all that checks out...

Put the new ignition coil in. Fired right up and revs like it should. Had to modify the coil a little to fit the box and modify the e-box by cutting the tube that holds the removable fuse down. Now...

That was my first idea, to jb weld the low spots and have the machinist clean it up to make it flat again, this way he’s not taking anything off the base of the cylinders and changing compression on...

I brought the newly bought cylinders to the machinist. He is concerned about the base surface of the cylinders. It looks like somebody used a pry at to remove the cylinders from the case and marred...

So I took a 3 hour ride from western ma down to northern New Jersey for some parts. I got a stock bore set of cylinders, a cylinder head, a set of cdkII carbs, an intake for cdkII (the non equalized...

Frustrated with this machine and playing with the carb I did a ton of research and found some really good info. Satisfied with my fuel system and carb I moved on to electrical testing. I tested all...

I put a new needle and hanger, as well as a new O ring around the seat. I didn’t replace the brass seat because I ordered the wrong size. I ordered a 2.0 and took mine out and it was a 1.5. But...

Ok so I took the air box off and removed the head. What I found was the no piston has huge hole in it(already knew that) but I found that all pistons were stamped 1.00 so they are bored out cylinders...

Ok I need a little info from someone who knows the differences between the di engines and the carb. Basically my question is this: can I get an 1100cc motor that is di and swap the head to a non di...

I’m located in western Massachusetts, and I ride the Connecticut River. I don’t mind a little porpoiseing since I like to hit the wakes and catch some air((really I’m just trying to throw her off so...

Didn’t pay that much for it. Got the ski and the trailer for 600 bucks. I could easily part it out for that but I’ve been looking for an 1100 or 1200. I got two 93 vxr 650s but I need something...

Needle valve and seat didn’t come in the kit, just different springs. I tried one that looked the closest to the old one. Ended up putting the old one back in. Got a little better but still bogging....

Ok so I was looking at the ski to buy it. I just got it home and no 1 piston has a hole in it. It was confirmed that it is a sbt engine installed by dealer two years ago and has about 15 hours on it....

Not sure what the engine is. All I know is it is all silver and not painted green like all the stock engines I see.

Hey guys, 03 Kawasaki zxi1100. Had a brand new engine installed two years ago by dealer. Has 15-20 hours on it tops. Now cylinder no 1 has no compression. Nothing. Any ideas what could cause this?...

I have two identical vxr650s both are 93’s. One runs like a champ. Hits about 35 and never lets me down. The other came to me in pieces. Long story short I bought a motor off eBay and installed it....

Wow 70+ views and not one reply...what a useless forum

New to forum and jet skis. So anyway I just picked up two Yamahas, both 1993 vxr 650. Not to mention the piece of scrap metal they came on I was told was a trailer lol. Anyway one started with a jump...
