Default 1988 Indy, chore list ...

Hi All,


I'm new to hcs, just got a new-to-me 1988 Indy Trail, project sled for my 8-year-old son and I. She's already my sweetie, and has given me her best gasps, hopefully she and I and my son will have a lot of happy years together, she's a beautiful angel. I don't have the service manual yet, but I ordered it. So for now ...



1. Someone who didn't know the sled, put regular motor oil into the oil-bottle. I suspected right away when I noticed that there was about a quart of black stuff in the bottle. "Why so much? ... oh ..." I have to suck out as much as possible, then dissemble, clean out, add the burnable stuff.


2. Change fuel line, a patch was done with flow impedance. Drain fuel tank.



3. Clean out carbs. Lubricate throttle and brake cables.



4. Clean out clutches and belt.



5. Patch splintered fiberglass, replace noise barrier.



6. Sew a new seat cover, sand fiberglass, paint, redo body graphics, etc.. The boy has some specific things that he wants to do with the sled.



7. Replace spark plugs, check toolkits and supplement for field-repair kit


8. Register sled with State of Colorado, outfit gear.


I love the simplicity of that 488, it's a thing of abject beauty.

Maybe take smell test of the oil first before you drain it....does it smell like old used motor oil? If so they must do it different in colorado with sleds. You may be getting into more with this sled than wished for.

I pulled some out, it smells like motor oil, and has the viscosity of 40-weight. No big deal, she'll be fine when I get her cleaned out. I think it was the transitional owner who didn't know about oil injectors.

That 488 is a thing of beauty, so simple. I hope to learn a lot from you guys and gals over the next few months about these sleds, there is a lot to read here, much of it really valuable.

on ebay, they do have seat covers for sleds, no names on it but easy to install....take old cover off, place new one on, staple ( and glue) it down...For carbs, they have kits for the 488 to refresh both carbs. check chaincase and refresh the gear oil too.

While at it, have both clutch's inspected or replaced for excessive wear on all bushings, weights bearings and pins....both springs likey also. You can have the bearings on the driveshaft and jackshaft fail pretty common on those old indys if original or never greased, i'll ruin your day so its good they be checked or replaced to. Not to discourage you, but sometimes maintenance on these older sleds isn't as simple as just gas and go.

Those Fuji piston port motors were really good engines, and the 488 has proven the test of time. That's what I had in my 90 Trail, and it always started on the 2nd pull, always. It never had a great amount of power, but that engine never failed me.

Those 488's were pretty decent for guys that rode with us in quebec. I could remember only engine failure with the motor locking up from throwing a rod. Its all the bearings in the chassis that can crap out at anytime that these sleds whether a blower or liquid had.
