    It's all here: http://www.largiader.com/slash5/

    Still gotta fix that cylinder head, and get a lighter exhaust, make a race seat, maybe hack the subframe, bump the compression, dual-plug it, install better gearing, and loads more.

    The bike had a persistent loss of power until I got home and adjusted the valves. But at the same time I adjusted the valves I got rid of that mix of OK and old gas - I live close enough to the on-ramp that there's an outside possibility that i didn't pull the bad gas into my carbs until about that same time.

    And I've never had head work done on the bike. It was down for a swing-arm issue. I never had the motor apart.

    Well I hope it all works out.

    Meanwhile, who are the smiley designers around here? I was looking for a "blow sunshine up his ass" smiley and couldn't find one. :rofl

    Ride more, worry less. The bike runs fine, thank the m/c gods, go have fun...spring is here :clap

    BTW while not recommended, 8K for a minute or so, will not kill your engine.

    I'd think if you bent a valve it would idle pretty rough. Since you didn't mention that, I'm assuming not. Explain what you mean by 'running poorly'. No power or acceleration could have been caused by both sides bending valves, I guess.

    You could do a compression test - that's an easy ten minute job. Doesn't everyone have a compression tester? If not, go to a used tool store and get one for a few bucks.

    That will tell you whether compression is good or not.

    Now might be a good time to find out how Burt Munro (worlds fastest Indian) straightened his when they got bent.

    It seems to be OK. I'm running it for 300 mi (1 tank of gas) and then I'm going to check the valves again. Depending on drift/direction I think i'll know. And I'm going to get a compression tester this weekend.
