OK I've been visiting the forums for a few months after buying my 1989 LT500 last July. After the purchase I had the top end done. New 86.5mm Wiseco piston and my buddy did a bit of mild porting. Stock TM38mm carb rebuilt (new valve needle). Also did new steering wheel bushings and SB Designs lower bushing. New rear shock bearing kit. Went to a 13 tooth front sprocket from the 12 it had. New (used) fmf full exhaust removing the stock it had ($63 off ebay!). All fluids changed couple seals (clutch and kick). It had V2 reeds already.
I'm hoping to get a case saver (SBLT check your messages!).
I had this out in the Oklahoma dunes for a few days and it ran great. I ran a foam filter with a 22.5 slow and 350 main and the Plug looked good.
I just really hated the airbox.
So I bought one and put in the SB clamp on adapter kit (which I have NOT put in yet). I also ordered an AEM filter (One that fits in the airbox) along with a pre-filter and will run with the air box lid OFF. So as of right now I put in a 25 slow jet and a 420 main to start. I won't run it until I get to Glamis and will check the plug immediately (Cold and too much snow in WI). My only thought is if I should actually start fatter on the main. I'd love to hear from someone that has a pretty stock bike as to what their main is at with the lid off.
Taking it to our 4th annual Glamis trip in a couple weeks and it will be my 1st on a 2 stroke. Just looking for things to make the trip as break down free as possible. I would love feedback on things I'm missing or should try to do prior to the trip.
I've got a couple days lined up in a heated garage to get the airbox mod, nerf bars I got from Dennis Kirk (last pair they had), case saver and a TTO temperature gauge installed.
The airbox mod is simple and sano!
I bought a spare airbox and have it done - just got to get it in the bike now. Here is a picture of the AEM filter vs. a K&N
looks like you're about there. I need to get back out to Glamis. Was incredible fun!
a mostly stock 89 with a high-flo filter and an FMF pipe will prolly need about a 380 main but it's always good to start fat at you stated. 25 pilot sounds about right. You'll prolly need to adjust the air mixture screw a bit to get the idle perfect.
While you're at glamis, test your needle height as well (half throttle plug chops).
Have fun - seriously jealous here.
I better bring a dozen plugs!
I failed to mention that it passed a leak down test this week which passed
Add rear axle bearings as well as both fronts to the list..... $$$$
Don't forget the important part... Bring a spare quad. Can't seem to trust them darn Zillas anymore these days.
I look forward to meeting you there GL
Spare quad well that isnt going to happen. The group of 8 of us will have an extra.....hope Im not the one needing it
Seriously though - make sure every nut and bolt is tight. Too many times its something stupid that falls off or creates havoc. These thing buzz and vibrate so do a good inspection.
Yea that rack has been on my radar for some time (but what rack isn't!
)
But this trip has me taxed and I just can't afford another $200 (or should I say if UPS shows up again my wife my shoot them or me!)
Looks like a big Gatorade bottle in my backpack will have to work for spare gas!!!
