I just picked up a used yz85. I put a new spark plug in it and rode it around for an hour and then took it out and this is what it looks like. Does it look lean? The insulator looks really white to me. It has stock jetting and the bike is completely stock so i would think that it should be...

So i did a plug chop with the stock 230 main jet, and then i did a plug,chop with the 250 main jet. When looking at the plugs, i thought the brown ring was supposed to be right on the bottom. But on both plugs, the color seems to be in the middle/upper area of the plug. How does my jetting look...

Okay so a few months ago i rebuilt my blaster top end. I had the cylinder bored to 67.5 and hones and chamfered. I put in a new wrist pin bearing, and a new piston kit from pro x. My bike has stock jetting and everything stock except it obviously is bored to 67.5, it has tors and parking brake...

Okay so I had another thread open but it started out as a different issue that I ended up fixing, and then I started talking about this problem but I figured I should start a new thread specifically about this problem. So recently I rebuild my blaster. I took the cylinder to a machine shop and...

I just rebuilt the top end on my blaster. It was running good. I have about 4 or 5 hours on it. Then all of the sudden in the middle of a ride, it started bogging real bad if you went past half throttle, to the point where it would actually shut off. The parking brake and tors is already...

I just rebuilt the top end on my blaster, it ran alright before the rebuild. Now it idles fine, but the second I hit the throttle it boggs down and dies. Theres slightly more smoke than normal too. I cleaned out the carb too so that shouldnt be the problem

On my blaster the kickstarter does not always catch and turn over the motor. Sometimes when i kick, it just goes all the way down with no resistance. I have looked inside the clutch cover and i couldnt see anything wrong. Also i noticed that the kickstart hits the clutch cover when it retracts.

My blaster did not come with a rear brake caliper or fluid reservoir. I found a new cheap caliper off ebay for 18 dollars and a res on ebay for 18 dollars. Heres the links. Anyone have any experience with these? Is it worth the purchase? The used calipers I found were up to 100 dollars and id...

You guys have helped me so much with my blaster, so I figured I would see if you could help me on this one. I have an old 2 stroke polaris xplorer 300 that i can't get running right. It used to run great a few weeks ago. Then the starter went bad, so it sat for a week until i got the new...

I cant make up my mind between the toomey and the shearer. Which one sounds better? Also is one louder than the other? Im leaning more towards the shearer because of the bottom end power, but I like the toomey sound in the videos. Does the shearer sound similar?

I have bought the vitos dual stage carbon fiber reeds for my blaster, should I keep the stock reed stoppers on or take em off?

Ok so I recently rebuilt the carb on my blaster and changed spark plug and it ran really good. After a few weeks, now it drives good, but then when i pull in the clutch to slow down, half of the time it will stay running perfect idling, and the other half of the time it quickly dies when pulling...

I noticed my stock blaster was running a little rich i think because it was bogging a little when i punched the throttle, so I cleaned the air filter and took apart the carb and cleaned it. When i put everything back together, now the bike starts and everything like normal. It no longer feels...

Ok so i have a 2005 blaster and one of the bolts that holds on my clutch plates came off and tore up some stuff inside the clutch cover. It messed up my kickstarter spring, but that's not really a big problem. What im concerned about is it put a hole a little to the left of the clutch assembly...

I just bought an 05 blaster and I think the cutch is starting to go bad. It feels like my low end power is not as good, and it revs high in 2nd gear pretty quick without as much speed as it used to in 2nd. How would I go about fixing the clutch? Im completely new to this and dont have any...

On my 2006 yamaha blaster, my tranny oil drain plug is stripped, so I cant drain the oil. The sight glass is conpletely dry though, even after running it for a minute and letting it all drain back doen in there. I thought that it had no tranny oil, so i went to put some in and if i just barely...
