whats a YZ490?? is it a 2 stroke?? or is it a yz426 with a big bore kit??

i wanna see pics of a lowered cr500 also

The 490 is an old yam. 2 stroke, am i right? Twin plugs in the head, foul one, swap the cap to the other..?

 

[Yunggunnazracing]

you are right on the Yam 2 stroke. Most of the 490's had one plug, they may have made a year with twin plugs. So what the times look like to you all??

 

[Hillclimber361]

The times look pretty fast to me. Last week the hill was 200 feet, and the top time on a 250 was 6.9 secs. The top 500 time was like a 5.8 or 5.9. This is with a breaker though and it was a slow day, a little wet. But those times seem to be cruising to me. How good did you do? Were you the one talking about the kx 500 a lil while ago? Also, why don't you climb ur bikes. It's just a verticle drag race.

 

[Yunggunnazracing]

Naw, cant mess with that LOL, give me a horizontal strip and i can do something. Yeah i was talking about the KX 500, we have a few 500's.

ok i need some info on this "YZ490" i was just talking to Big K last night about how of the big 4 yamaha was the only co. that didn't make a 500cc 2 stroke. well i guess i was wrong. anyway that might be cool in a banshee frame. i need any info you guys can get me. liquid cooled or air cooled??

 

[Yunggunnazracing]

The one i have is air cooled and putting down around 65-70 HP. My dad builds the motors. Any other questions about it, just ask.

 

[370banshee]

iof you have any extras i'd be interested in a trade for my suzi 750 triple

 

[Yunggunnazracing]

Any 490 Parts?? What Kind Of Extra's??? Let Me Know, i really want a triple.

 

[370banshee]

[Yunggunnazracing]

[370banshee]
