I guess I am the new kid on the block here as I just joined. I live in Moose Jaw Sask the land of little snow and lots of cold.
So I have a 86 Indy Trail 488 fan that has seen better days body and seat wise but the engine still ran ok except for losing power and dying after abt 25 min. Wait 10 or 15 then go again.. Anyway I will get a new CDI for it and see if that cures it or will have to get a stator possibly. I have a chance to get a complete 86 Indy 600 that needs a rebuild according to the owner for $200.00 , I haven't seen the sled yet but was thinks if the body was decent that I would put my 488 in it. So the question is such.. Will a 488 fit in a 600 Indy sled or are they totally different beasts and if the 600 was decent would you do an engine rebuild versus the swap I just proposed or are the 600's not a good engine as I have heard that from a few people as well.
Well I went and looked at the sled last night and took a whole 30 seconds to decide 200 was a deal. The fiberglass is in nice shape and the 2 up seat looks almost new, the seat alone was worth the asking price. Track and everything is very good probably a 7 or 8 overall. The 600 triple is disassembled and in a box, the guy bought it that was to fix up for his kids but like most people has no time and when he saw my add looking for a parts sled decided it was time. I had a quick look at the pistons and cylinders and there is no obvious damage to anything so I will probably take it to the engine shop and have it hot tanked (yes I know it is aluninum and they have a special tank just for that stuff) Then I will decide on do a rebuild on it just for giggles and put it away. I will have to get a heat exchanger as it seems it is missing in action. Soo next stop is installing my 488 Fan in it (should be a direct drop in) and I will have a very nice 2 up sled for the wife and I.
If you are putting the 488 fan in it, why do you need a heat exchanger? Are you planning on reinstalling the 600 after you get it rebuilt? Just curious...
The liquid cooled 600 had three heat exchangers, two under the running boards, and a crossover at the rear of the tunnel. You can find a diagram of the system on the Polaris web site
Well after looking more at thing it looked easier to do a rebuild on the 600 so I got .040 over Weisco ultra light pistons (it had been bored onece before) and a full gasket set for $185.00cdn delivered. And will get it rebuilt at the local engine shop. I needed a CDI for the 488 that was going to cost $114.00 and the swap was going to require some reengineering of the engine mounts on closer examination so I will finish the 600 Indy up to use and keep puttering around getting the 488 trail done over the next couple years.
Thanks for the link to Polaris too. And the heat exchangers are there just didn't know what I was looking for.. Nubies Eh.
