1991 Polaris Indy 650
Hi all, so i took the carb adapters off the engine. The inner sides of the engine side look like they are peeling apart. Should these be changed?
Its a '91 indy 650. No carb adapters available from anyone. Polaris or after market. Apparently the '77 polaris TX 340 is the closest I will get to the original.Yes they can, Kimpex and others make them. Will find you the part numbers for this as well in a few minutes.
Remind me again what snowmobile this is? I know it is a 650 IIRC just not sure on the year.
The intake ports on the '91-'92 650 are bigger than any other year. Apparently that's why the adapters are no longer available because they wouldnt sell enough.You can find them. I replaced them on my '88 650 and they are only 34mm carbs iirc. Gimme a few minutes looking through other threads as well and then will work on this.
Polaris used the same cylinders as the rxl for '91-'92 indy, which had bigger intake ports than the previous carbed 650. If you look at the cylinder part numbers they are the same as the rxl but different than previous year carbed 650.Well I just learned something new...the 34mm and 38mm carbs use a lot of the same ones. Idk about the ports being bigger that seems odd to me, I never heard that working back at Polaris in the mid '90s but that was 25 years ago. Just started to look.
Th. Part# for the original adapter is 3084228. No longer available and I havent been able to find one after market either.Well this is odd...it really is. I looked at 2 places one says this will work on that snowmobile the other says no. MFG Supply says this is the carb boot that will work and dennis kirk says no.
I am going to keep looking as this is bothering me now. I may have to pull out one of the old books from the mid 2000s to get a part number.
I think I'll buy one and see if it matches up.So? OEM numbers change all the time, ESPECIALLY Polaris!! And yes I saw that number. I would try them. Multiple places say they will fit after looking some more. Do you have anything to lose over 25 bucks total?
