Best pass at the strip with my GS 1100

[nastyjones]

When you chop the throttle at 10,000 rpm the engine rpms drop fast. The big magnet and starter clutch try to keep spinning at 10,000 rpm even when your motor has dropped to 8,000 rpm. Not a good thing at all.

Just a side note, I pull the clutch in now as soon as I go through the traps & let the revs drop.

MPH on that pass does show up briefly at the end of the video. 113.11. I've since gone to a one tooth smaller sprocket so I can shift into fifth before the traps but everything seems to have slowed down. My et's, my 60's & my mph. I think I'll put the old sprocket back on. I'm racing this Sunday at Grand Bend Motorplex & will report back.

Cheers,
Paul

113 MPH is good. Around 108 with my GS.

Not had a whole lot of problems with the magnet. I use the engines oil pump to feed the turbos, so cutting off the oil supply at full boost may not be such a good idea in this case.

average fast street bikes needs to go through in 4 gears(topped out)right before the rev limiter(1/4 mile).
the reason i say 4 gears is because if it is a street bike this still leaves you enough gear to ride around without the engine revving really high.
gear it to go through in 5 and you will no longer have a real street bike...you will hate it unless it's just for around town use.
also you need to check water grains and altitude each day you race so you know what to do on gearing/jetting or you will be chasing your tail-scratching your head wondering why the bike slowed or picked up for no reason.

I used to just switch the counter shaft sprocket. It was a quick and easy change. Now on my bikes with the the adjustable wheel base I change the rear sprocket. I very seldom use the same gearing or wheel base on the street as I do on the drag strip. It takes me a little less than an hour to switch the bike from street to track. But for those who just mostly ride their bikes on the street and don't care about getting the quickest time possible more or less just want to see what she will run then I would say just run with the gearing you ride with normally.
