Hey Vmax540 thanks for the kind words. compression check is the first thing on my list. What can I say, I fell in LOVE with the old VMAX the first time, I saw it :wink: I've won alot of races with the old boy. Yamaha should be proud, that a 26 year old sled is still competitive with the new technolo...
Hi SRX500F82 what yamaha has those pipes? I would like to gain 5-6 mph! The compression should be about 150psi or less? In 19 years, I have had it the motor has never been torn down.

Hey vmax-540 thanks for the info. I have to agree with crwdog, I hate to say but the 501- 600 multi class is getting very tough to compete in. The VMAX just isn't fast enough and doesn't have enough HP :roll: :roll: The Improve 501-600 multi class is running speeds of 113mph in 1000 ft! That's way t...

Bob Vehring trust me, I get teched hard I even get asked ,what I am running for fuel Also the tech shack '' Yup been their before and the tech found nothing BONE STOCK!
pre '92 600cc trail sled may be bumped up to pre'99 600cc trail sled. If that happens, maybe I need to sell off this rocket ship and look for a '98 SRX600 !crwdog, I love racing the old VMAX, but it's getting to the point like you said the old VMAX just doesn't have enough speed or hp to run in this...
chrisrider63 I hate to break the bad news,but your polaris clutch at a radar run put's you in the Improve class 501-600. The winning speed was 113.3 mph in that class :roll: :roll: ok. Im sure it wouldnt get destroyed the polaris clutches are a big improvement... Wear a full face helmet with a shiel...
