I was just wondering if anybody had some tips on turning a Stock XL 600 into a bad @ss machine.. Please reply and let me know I just picked it up recently, and was hoping for some helpful hints.
Thanks

Step 1. Sell XL600

Step 2. Buy bad @ss machine.

I still own an 86 XL600. I rode it for the first time in quite a while last weekend before the Vikings race in Lucerne. Other than the super soft comfortable seat, it is an outdated, undersprung, slow revving, under-torqued, bad handling, low clearance, dirt-legal street-bike.

Don't throw money at that bike. Accept it for what it is. If you want something else....buy something else.

They really aren't that slow, Mine would run with a buddy's yz250 which was just rebuilt and had a few mods done to it. the thing is, my xl600 had burnt valves and carbs that needed overhauled and tuned. check out xrsonly.com for the high perf. parts that are available. aside from that there is not a lot of high performance parts available. I was looking for parts for mine and called a junk yard and the guy tried to buy it. when i asked why. he said he wanted it for a race engine. if it's good enough for that, it's good enough for me. just remember they develop their torque at low rpms, i like that because it gives me a good sense of control while climbing hills.

I GUESS that's possible, but highly unlikely.

Do you have a dyno sheet, or pics of your turbo/NOS/super charger/propane injection setup?

:D

Get an aftermarket cam, have the head ported, and perhaps go with a 101mm or 102mm over bore. The overbore will net between 600(101m bore) and 618cc(102mm) of displacement versus the stock 589cc. The XL600s actually had the highest factory power rating of the aircooled XL/XR line.

Everything HeadTrauma said PLUS free flowing exhaust, air filter and the biggie, JET THE CARBS! Even if you don't do anything else, richen up the jetting. Not only will you pick up some power but it will be easier to start as well. They are painfully lean from the factory. :D Bruce
