89 phazer carb jetting w/DG pipe - Snowmobile Forum: Your #1 Snowmobile Forum

New to site and would appreciate some help. I have an 89 Yamaha phazer, .20 over with a DG pipe. Need to know what the carbs need jetted at for the pipe. I live and ride in Northern Indiana so high altitude is not a concern.
Thanks

Go up at least 2 sizes and check plug color. Should be a nice tan/coffee color.

Thank you for the reply, the problem is I don't know what the stock size was. The sled was bought with the pipe on it and was re-jetted but is slow off the line. I also have a stock 87 Exciter, I would think the Phazer with a pipe and correct jetting should be somewhat comparable to my exciter. The phazer is for my Wife and hauling the kids on the sled but its not doing me any good running doggy and I don't want to do any engine damage.

stock jetting is 143.8 for the main and 95 for the pilot. with a pipe run around 145 to 100. herd these numbers on another forum.

If the plug color is good, the problem is either reeds or clutching.
I am leaning towards clutching since most people will not recalibrate after making pipe changes. The set up needs to be changed to accommodate the different power band characteristics.
