After reading a few threads, it seems like what i want is a 1990+ motor, correct?

it seems like the 89 is very similar, except the clutch is more narrow. Has that been a major issue?

I ask because an 89 popped up locally that i may be able to get for a decent price, BUT if the narrow clutch can be problematic, I will definitely keep looking.

I am definitely wanting maximum parts interchangeability, which seems to come from the 90-01 motors. I dont want to have an issue in 5 years finding parts for an older, less produced motor. If I go through the trouble to build one of these monsters, I dont want to shoot myself in the foot.

I think that 89 - 01 are the same except for the tranny 89 - 93 are close ratio trans and 94 - 01 are wider ratio.

Not according to these pics, provided by Roosty. The 89 seems to have a one-year only case, and a narrower clutch. I was mainly curious about the narrow clutch being a problem. But now that you mention the tranny, I will probably focus on finding a 94+ bike. I forgot about the trans differences.

Huh i thought they were the same but i guess not but i would definitely go 94+ so as bob says you can go faster then 48 miles per hour.

93 tranny is wide ratio? isnt it ? the early ones are too.

Im pretty sure it 94 and up but im wrong constantly in my daily life so this may be no different

93+ is wide(r) ratio

Don't feel too bad.
I'm right there with ya

People act like that HRC gearset ( Or the Mad Man Eng. copy) is the "Holy Grail"

Dropping high gear from .79 to .75 aint much.....

I have been running a 1992 Trans for years, it will still make your eyes water when its wide open, never had a problem keeping up with people.

I never had an issue with the clutch being a doisk shy in my '89 running in the sand with a paddle, it awaays was a runner too. if you're still looking at the '89, some of them have the mag side cover so beware of that.

Desert, dunes, and fire roads are the only place I can see a 500 at WOT for very long. My '92 is a close ratio and I'm seldom in high gear.
Wear goggles, your eyes are gonna water!
