I think you are talking about the small elbow on top by the serial #. If so that is just a vent for the gear case. Nothing was attatched to it from the factory. Make sure it is open to prevent preassure buildup in the case. You could run a vent line off of it like they do on a Mic carb but it really...

I can see that your cylinders have been sleeved. You need to check the depth of the o-ring groove that seals the head down at the cylinder. I have seen sleeved cylinders that have a deeper groove than what a stock chrome bore cylinder would have. The depth of the groove should be the same for both i...

No Bob I've never talked to Olaf on that. I'm sure it works though. I was being somewhat sarcastic in my last post (I have an issue there lol) but the basic premis is that bigger carbs will make an improvement on almost any engine if the work is done to allow it. On a stock 540 there is no need for ...

How about the 81 srx 440 with 44 and why did bender put 44 on his 540 s if there was no power gain. I am looking for a base line set up for a 81 440 with 40mm carbs and there specs for a Polaris wide belt overdrive setup Richards perfomance sold back in day I trying to set a 81 srx for speed runs o...

Cool!! Thanks fer posting.

I have one of those jackshafts and secondarys. Like to try it someday just never get the time. Something always seems to come up.

OK Bob. I hear ya. I'm not telling anyone what to do with their sleds on oil, mix, premix, stock, direct injection etc. All these methods of supplying oil to a two stroke work and whatever works best for an individual is fine by me. My only peeve is that many talk of this "lean oil" deal a...

Hi Bob, read your PM. Responding to it and your post here so others can see what's in me brain too. For starters I have made my thoughts on the "lean oil" theory clear on many different sites as this subject on Yammie injection methods come up often. I'm not trying to stir up trouble and d...

When looking at the carb from the airbox side the outlet (for fuel to the carb) for the PJ system is at about 9:30 (clock hand). The fuel transfer line from the bowl of the carb attaches to it. It is not in the main air flow line through the carb and without the airbox on there is not enough vacume ...

My thoughts. Offset domes? Dono, Yammie has done it on some and not on others. Fan and liquid cooled. Could have something to do with directing combustion to even heat dispersal. Turbulance in a combustion chamber happens and no two designs are the same. Air intake and exhaust causes flow and I can ...

The head on the right is stock. The one on the left has been cut and redomed. There are many reasons to do this including just repairing a head that has been damaged from a burn down. Raising intake/exhaust ports decreases the amount of compressable air space on the top of the piston so it can lower...

In you pics the head on the right has been cut. You can tell but the fact that the black area by the T-stat is gone. All factory uncut heads will be like the head on the left in that area. I wouldn't run the cut head on a stock engine without having it cleaned up and redomed to make sure it's right....

The pic isn't very clear but the engine looks like a 540 to me.

Nice looking sled. The seat is off a Vmax.

Good Luck, opsled

New 81 SRX seat cover. OEM Yamaha not a repro.
